Footwear fastening system

Cross Reference to Related Applications

Priority of U.S. provisional application serial No. 62/657,267, filed on 13/4/2018, the contents of which are incorporated herein by reference in their entirety.

Technical Field

The present teachings generally include footwear having an upper and a fastening system configured to facilitate foot insertion and tightening.

Background

Footwear may include a sole structure configured to be positioned under a foot of a wearer to space the foot from a ground surface. An upper attached to the sole structure receives the foot. The fit of the upper to the foot may be adjusted by the fastening system so that the upper is loose enough to receive the foot, but may tighten around the foot to secure the foot relative to the sole structure. For example, a closure system, such as a lacing system, may include laces that are tied once the foot is received within the upper. Traditionally, placing footwear on the foot typically requires the use of one or both hands to stretch the ankle opening of the upper and to retain the rear portion during insertion into the foot. The fit of the upper is then adjusted after the foot is inserted, for example by tying a lace.

Detailed Description

An article of footwear is disclosed that facilitates relatively easy foot insertion and removal and secure adjustment. The article of footwear includes a sole structure, an upper secured to the sole structure, and a plurality of tensioning cables having proximal ends secured to at least one of the upper or the sole structure. A plurality of tensioning cables extend out of the upper. The proximal end of the strap is connected to the distal end of the tensioning cable. The strap also has a distal end releasably secured to the upper to tension the tensioning cable. The webbed spacer is secured to the plurality of tensioning cables. The webbed spacer extends between adjacent ones of the plurality of tensioning cables, and adjacent ones of the plurality of tensioning cables are spaced from one another by the webbed spacer.

In one or more embodiments, the webbed spacer is a flexible polymer material. The webbed spacer may be disposed against the outer surface of the upper on the first side of the upper when the distal end of the strap is secured to the upper. The webbed spacer may be relatively thin and flat, allowing it to conform to the shape of the outer surface of the upper against which it is resting. Because the webbed spacer abuts the first side of the upper when the strap is secured to the upper, the webbed spacer may help prevent wear of the tensioning cable under the force against the first side, particularly as compared to a tensioning cable disposed on the first side but not coupled to the webbed spacer.

In one or more embodiments, the webbed spacer tapers from the proximal edge to the distal edge, and the spacing between adjacent ones of the plurality of tensioning cables decreases along the webbed spacer toward the band. The width of the band may be narrower than the distance from the foremost tensioning cable to the last tensioning cable at the proximal ends of the plurality of tensioning cables. The spacing between adjacent tensioning cables of the plurality of tensioning cables decreases from the proximal ends thereof to the distal ends thereof.

In one or more embodiments, a plurality of looped cables are secured to at least one of the upper or the sole structure and extend out of the upper. The plurality of tensioning cables extend through the plurality of annular cables between the proximal ends of the tensioning cables and the webbed spacer. For example, a plurality of tensioning cables can extend upwardly from proximal ends of the plurality of tensioning cables along a first side of the upper, and a plurality of looped cables can extend upwardly from a second side of the upper. When the distal end of the strap is secured to the upper, the webbed spacer abuts the outside of the upper and the plurality of tensioning cables turn at the plurality of looped cables.

The strap is secured to the upper by a single pull of the strap around the rear portion and pressing the distal end of the strap against the front portion of the upper. The article of footwear may be useful for quick donning as well as for persons with limited dexterity because no lacing or tying laces are required. To further increase the ease of foot insertion and removal, a fastening system including a strap, a plurality of tensioning cables, and a webbed spacer may be used with an upper having a hinged rear portion to facilitate foot insertion and removal. For example, in one or more embodiments, the upper includes a front portion and a rear portion. The forward portion is secured to a forefoot region of the sole structure. The rear portion is operatively secured to the sole structure at least partially rearward of the front portion. The rear portion is hinged between an access position and a use position. The foot-receiving chamber is more exposed (i.e., more open) in a heel area of the article of footwear when the rear portion is in the entry position than when the rear portion is in the use position, and the rear portion partially encloses the heel area in the use position. The strap is configured to wrap around the rear of the rear portion from a first side of the front portion to a second side of the front portion and to be secured to the second side of the front portion when the rear portion is in the use position.

The strap and the upper may have fastener portions that cooperate to help retain the rear portion in the use position when the strap is releasably secured to the upper. For example, the first fastener portion may be secured to the strap at a distal end of the strap, and the second fastener portion may be secured to a second side of the front portion of the upper. The first fastener portion is configured to be secured to the second fastener portion.

In one or more embodiments, the strap has a plurality of fastener portions spaced along an inner side of the strap, and the upper has a first side and a second side secured to the front portion and in some embodiments a plurality of fastener portions secured to the rear portion. The fastener portion of the strap is configured to be secured to the fastener portion of the upper. Spacing the fastener portions along the strap allows the strap to stretch between adjacent fastening portions if the material of the strap is more elastic than the fastener portions and enables variable positioning of the strap on the upper in a secured state.

In one or more embodiments, the rear medial edge of the forefoot portion interfaces with the rear portion at a medial interface and the rear lateral edge of the forefoot portion interfaces with the rear portion at a lateral interface, and the plurality of fastener portions of the upper includes a forefoot medial fastener portion and a rear medial fastener portion, both of which abut the medial interface. The fastener portion of the upper includes a front lateral fastener portion and a rear lateral fastener portion, both of which are adjacent the lateral interface. When the rear portion is in the use position, the strap passes over the medial abutment and the lateral abutment and the plurality of fastener portions of the strap are secured to the forward medial fastener portion, the rear medial fastener portion, the forward lateral fastener portion, and the rear lateral fastener portion. In another embodiment, a single fastener portion extends rearward from the medial side to the lateral side.

Additional features may be included to assist in hinging the rear portion to the use position and/or to maintain the rear portion in the use position. In one or more embodiments, a magnetic coupling may be used. More specifically, the article of footwear may further include a medial set of magnetic elements and a lateral set of magnetic elements. The inboard group of magnetic elements includes at least one front inboard magnetic element secured to the inboard front portion and at least one rear inboard magnetic element secured to the inboard rear portion. The outboard group of magnetic elements includes at least one front outboard magnetic element secured to the front outboard, and at least one rear outboard magnetic element secured to the rear outboard. In the use position, the back portion is secured to the front portion at least in part by magnetic coupling of the at least one front inner magnetic element to the at least one back inner magnetic element across the inner interface and by magnetic coupling of the at least one front outer magnetic element to the at least one back outer magnetic element across the outer interface.

Alternatively, in one or more embodiments, the rear portion may be hinged by folding, such as from the use position to the access position by folding back, instead of or in addition to the magnetic element. In such an embodiment, the front inner side edge of the rear portion is closer to the rear inner side edge of the front portion when the rear portion is in the use position than when the rear portion is in the access position; the anterior-lateral edge of the posterior portion is closer to the posterior-lateral edge of the anterior portion when the posterior portion is in the use position than when the posterior portion is in the access position. Depending on the girth of the ankle when the foot is inserted into the foot-receiving chamber, the use position of the rear part may be slightly more forward or more rearward relative to the front part, but in all cases more forward than the entry position. For example, for an ankle with a smaller girth, the anterior medial edge of the posterior portion is anterior and medial to the posterior medial edge of the anterior portion when the posterior portion is in the use position, and the anterior lateral edge of the posterior portion is anterior and medial to the posterior lateral edge of the anterior portion when the posterior portion is in the use position. In other words, the rear portion is folded slightly inward of the front portion, relative to the medial and lateral sides of the upper. For an ankle with a greater girth, the front medial edge of the rear portion is adjacent to but slightly rearward of the rear medial edge of the front portion when the rear portion is in the use position, and the front lateral edge of the rear portion is adjacent to but slightly rearward of the rear lateral edge of the front portion when the rear portion is in the use position.

The anterior portion may be configured to help avoid the tendency of the anterior portion to collapse during foot insertion under forces that slightly misalign the foot with the foot-receiving chamber. For example, in one or more embodiments, the medial and lateral abutments are substantially vertical in that the posterior medial and lateral edges of the front are substantially vertical and entirely in the heel portion of the footwear. This arrangement may provide greater resistance to collapse and collapse of the anterior portion during misleading foot insertion than the anteriorly angled posterior medial and lateral edges. In addition, in embodiments having a lateral set of magnetic elements adjacent to the interface and a medial set of magnetic elements, the magnetic elements and any receptacle for the magnetic elements may help provide greater lateral support when the rear portion is in a use position, particularly in a rear use position, particularly when the medial and lateral interfaces are substantially vertical and entirely in the heel portion of the shoe.

In one or more embodiments, an article of footwear includes a sole structure and an upper that includes a front portion and a rear portion. The forward portion is secured to a forefoot region of the sole structure and partially defines a foot-receiving chamber on the sole structure. The rear portion is operatively secured to the sole structure at least partially rearward of the front portion and is hinged between an entry position and a use position. The foot-receiving chamber is exposed at a heel region of the article of footwear when the rear portion is in the entry position, and the rear portion partially encloses the heel region when the rear portion is in the use position. A plurality of tensioning cables extend upwardly along the front portion from a proximal end secured to at least one of the upper and the front portion of the sole structure. The proximal end of the strap is connected to the distal end of the tensioning cable. The strap is configured to wrap around the rear portion from a first side of the upper to a second side of the upper. The fastener is configured to secure the distal end of the strap to the second side of the upper. A webbed spacer is adjacent the proximal end of the band and is secured to the plurality of tension cables. The webbed spacer extends between adjacent ones of the plurality of tensioning cables, and adjacent ones of the plurality of tensioning cables are spaced from one another by the webbed spacer.

In one or more embodiments, an article of footwear includes a sole structure, an upper secured to the sole structure, and a medial flap secured to a medial sidewall of the sole structure and extending upward in a midfoot region of the article of footwear. The article of footwear includes a plurality of tensioning cables, a plurality of looped cables, and a strap. The tensioning cable extends upwardly along the lateral side of the upper. The looped cable is secured to at least one of the upper or the medial flap. The proximal end of the strap is connected to the distal end of the tensioning cable. The distal end of the strap is releasably secured to the upper to tighten the tensioning cable. A tensioning cable extends through the looped cable between a proximal end of the tensioning cable and the band.

In one or more embodiments, the article of footwear may include a webbed spacer secured to the plurality of tensioning cables, the webbed spacer extending between adjacent ones of the plurality of tensioning cables, the adjacent ones of the plurality of tensioning cables and the webbed spacer being spaced apart from one another. The inner flap may be secured to the proximal end of the webbed spacer. When securing the strap to the upper, the medial flap may be placed against an outer surface of the upper and cover at least some of the plurality of looped cables. Both the plurality of tensioning cables and the plurality of looped cables can extend through the upper.

In one or more embodiments, the medial flap is configured to have a first portion extending rearwardly and upwardly from the sole structure and to have a second portion extending forwardly and upwardly from the sole structure. The second portion is at least partially rearward of the first portion at the sole structure.

In one or more embodiments, the medial flap is an outer medial flap, and the inner medial flap is secured to a medial side of the upper and is disposed between the upper and the outer medial flap. The looped cable extends from the inner flap to the outer inner flap.

In one or more embodiments, the medial flap is an outer medial flap, the inner medial flap being disposed between the upper and the outer medial flap. The interior medial flap is secured to the foot-facing surface of the sole structure inward of the medial perimeter of the foot-facing surface. The looped cable extends from the inner flap to the outer inner flap.

In one or more embodiments, the lateral flap is secured to a lateral side of the sole structure and extends upward along a lateral side of the upper in a midfoot region of the article of footwear. Each of the plurality of tensioning cables may be secured to the outer flap and may extend from a free edge of the outer flap.

In one or more embodiments, the outer flap has an inner layer and an outer layer. The outer layer has an opening, and at least one of the plurality of tensioning cables extends through and is exposed at the opening.

In one or more embodiments, the webbed spacer is secured to the plurality of tension cables between the ring cable and the band. A webbed spacer extends between adjacent ones of the plurality of tensioning cables such that adjacent ones of the plurality of tensioning cables are spaced apart from one another by the webbed spacer. When securing the distal end of the strap to the upper, the webbed spacer may abut against the outside of the upper with the plurality of tensioning cables turned at the plurality of looped cables.

In one or more embodiments, the first fastener portion is secured to the strap at a distal end of the strap, and the second fastener portion is secured to the upper. The first fastener portion is configured to be secured to the second fastener portion.

In one or more embodiments, the upper includes a front portion and a rear portion that form a foot-receiving chamber. The forward portion is secured to at least a forefoot region of the sole structure.

The above features and advantages and other features and advantages of the present teachings are readily apparent from the following detailed description of the modes for carrying out the present teachings when taken in connection with the accompanying drawings.

To facilitate and clarify the subsequent description of the various embodiments, various terms are defined herein. The following definitions apply throughout the specification (including claims) unless otherwise indicated.

"articles of footwear," "articles of footwear," and "footwear" may be viewed as machines and articles of manufacture. Articles of footwear that are ready for wear (e.g., shoes, sandals, boots, etc.) and discrete components of the articles of footwear (e.g., midsoles, outsoles, upper assemblies, etc.) prior to final assembly into a ready-to-wear article of footwear prior to final assembly are considered herein and may alternatively be referred to as "articles of footwear" in the singular or plural.

The terms "a", "an", "the", "at least one" and "one or more" are used interchangeably to mean that at least one item is present. There may be a plurality of such items, unless the context clearly dictates otherwise. Unless otherwise indicated by the context clearly or clearly, including the appended claims, the numerical values of all parameters (e.g., quantities or conditions) in this specification are to be understood as modified in all instances by the term "about", whether or not "about" actually appears before the numerical value. "about" means that the numerical value allows some slight imprecision (with some approach to exactness in the value; approximately or reasonably close to the value; close). If the imprecision provided by "about" is not otherwise understood in the art with this ordinary meaning, then "about" as used herein denotes at least variations that may result from ordinary methods of measuring and using such parameters. Additionally, disclosure of ranges should be understood to specifically disclose all values within the range and further divided ranges. All references cited are incorporated herein in their entirety.

The terms "comprises," "comprising," and "having" are inclusive and therefore specify the presence of stated features, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, steps, operations, elements, or components. The order of the steps, processes, and operations may be altered, where possible, and other or alternative steps may be employed. As used in this specification, the term "or" includes any and all combinations of the associated listed items. The term "any" should be understood to include any possible combination of referenced items, including "any one" of a referenced item. The term "any" should be understood to include any possible combination of the claims recited in the appended claims, including "any one" of the recited claims.

For consistency and convenience, directional adjectives have been employed throughout the detailed description corresponding to the illustrated embodiments. Those of ordinary skill in the art will recognize that terms such as "above," "below," "upward," "downward," "top," "bottom," and the like can be used descriptively with respect to the figures, and do not represent limitations on the scope of the invention, as defined by the claims.

The term "longitudinal" as used throughout this detailed description and in the claims refers to a direction extending the length of a component. For example, a longitudinal direction of the footwear extends between a forefoot region and a heel region of the footwear. The terms "forward" or "front" are used to refer to a general direction from the heel region to the forefoot region, and the terms "rearward" or "rear" are used to refer to the opposite direction, i.e., from the forefoot region toward the heel region. In some cases, a component may be identified with a longitudinal axis and a front-to-back longitudinal direction along the axis. The longitudinal direction or axis may also be referred to as a front-to-back direction or axis.

The term "transverse" as used throughout this detailed description and in the claims refers to a direction extending the width of the component. For example, the lateral direction of the shoe extends between the lateral side and the medial side of the shoe. A transverse direction or axis may also be referred to as a lateral direction or axis or a medial-lateral direction or axis.

The term "vertical" as used throughout this detailed description and in the claims refers to a direction that is substantially perpendicular to the lateral and longitudinal directions. For example, in the case where the sole is placed flat on the ground, the vertical direction may extend upward from the ground. It will be understood that each of these directional adjectives may be applied to various components of a sole. The terms "upward" or "upwardly" refer to a vertical direction pointing toward the top of the component, which may include the instep, tightening area, and/or throat of the upper. The terms "downward" or "downwardly" refer to a vertical direction opposite the upward direction, which is toward the bottom of the component and may generally be directed toward the bottom of the sole structure of the article of footwear.

The "interior" of an article of footwear, such as a shoe, refers to the portion of the space occupied by the wearer's foot when the shoe is worn. The "interior side" of a component refers to the side or surface that faces (or is to face) toward the interior of the component or article of footwear in the assembled article of footwear. The "outer side" or "exterior" of a component refers to the side or surface of the component that is (or will be) oriented away from the interior of the shoe in the assembled shoe). In some cases, other components may be between the interior side of the component and the interior in the assembled article of footwear. Similarly, other components may be between the exterior side of the component and the space outside the assembled article of footwear. Further, the terms "inward" and "inwardly" refer to a direction toward the interior of an article of footwear or component, such as a shoe, and the terms "outward" and "outwardly" refer to a direction toward the exterior of an article of footwear or component, such as a shoe. Additionally, the term "proximal" refers to a direction that is closer to the center of the footwear component or closer toward the foot when the user inserts the foot into the article of footwear while wearing the shoe. Likewise, the term "distal" refers to a relative position that is farther away from the center of the footwear component or farther away from the foot when the user inserts the foot into the article of footwear while wearing the shoe. Thus, the terms proximal and distal may be understood to provide generally opposite terms to describe relative spatial locations.

Referring to the drawings, wherein like reference numbers refer to like components throughout the several views, various embodiments of footwear are disclosed that have the functionality of enabling a foot to be inserted and secured quickly and relatively easily, and with less manual dexterity required, relative to footwear that requires manual stretching of the throat area to enlarge the foot opening and requires securing by tightening and tying a lace. More specifically, referring to fig. 1, an article of footwear 10 has a sole structure 12 and an upper 16 secured to the sole structure 12. The upper 16 forms a foot-receiving chamber 18, and the foot-receiving chamber 18 is configured to receive a foot 20 (shown in phantom in FIG. 4) without manually stretching the upper to enlarge an opening of the foot-receiving chamber 18. Upper 16 is secured and secured about foot 20 by a fastening system 22, which fastening system 22 does not require any lace adjustment or lacing.

Footwear 10 as depicted herein is depicted as an athletic shoe configured for athletic activities such as basketball, but footwear 10 and fastening system 22 are not limited to basketball shoes or other athletic shoes. The fastening system 22 and other features of the article of footwear 10 may also be used in footwear for various other activities such as, but not limited to, running, tennis, soccer, etc. The fastening system 22 and other features of the article of footwear may also be included in an article of footwear that is a casual shoe, a dress shoe, a work shoe, a sandal, a slipper, a boot, or any other type of footwear.

As shown in fig. 1, footwear 10 may be divided into forefoot, midfoot and ankle regions 24, 26, 28, 31, respectively, of sole structure 12 and upper 16, with ankle region 31 being defined by upper 16. Forefoot region 24 generally includes portions of article of footwear 10 corresponding with the toes and the joints connecting the metatarsals with the phalanges. Midfoot region 26 generally includes portions of article of footwear 10 corresponding with the arch and instep areas of the foot, while heel region 28 corresponds with rear portions of the foot, including the calcaneus bone. Ankle region 31 corresponds with an ankle. Forefoot region 24, midfoot region 26, heel region 28, and ankle region 31 are not intended to demarcate precise areas of footwear 10, but are intended to represent general areas of footwear 10 to aid in the following discussion.

Sole structure 12 includes a midsole 32 and an outsole 34. Midsole 32 may be formed from a compressible polymer foam element (e.g., polyurethane or ethylvinylacetate foam) that attenuates ground reaction forces (i.e., provides cushioning) as it is compressed between foot 20 and the ground during walking, running, or other ambulatory activities. In further configurations, midsole 32 may incorporate fluid-filled chambers, plates, retarders, or other elements that further attenuate forces, enhance stability, or affect the motion of foot 20. Midsole 32 may be a single, one-piece midsole, or may be multiple components integrated into a single unit. In some embodiments, midsole 32 may be integrated with outsole 34 as a single sole. Outsole 34 may be one-piece, or may be several outsole components, and may be formed of a wear-resistant rubber material that may be textured to impart traction and/or may include traction elements, such as cleats, secured to midsole 32.

The upper 16 includes a front portion 16A and a separate rear portion 16B. In the embodiment of fig. 1-4, the portions 16A, 16B are configured to cooperate such that the rear portion 16B is movable from an entry position (fig. 4) to a use position (fig. 1) upon entry of the foot. This movement may be accomplished in a non-manual manner or a manual manner. For example, the other foot of the wearer may be used to move the rear portion 16B to the use position. As discussed herein, these and other features of article of footwear 10 enable the entry location to provide easy, hands-free foot entry into article of footwear 10. The use position is maintained by a strap 40 of the fastening system 22, which secures the rear portion 16B to the front portion 16A.

When foot 20 is positioned within foot-receiving chamber 18 of footwear 10, it is supported on the foot-facing surface of midsole 32. The foot-facing surface of midsole 32 may be covered by a lasting (not shown) that is secured to a lower region of upper 16. Moreover, in embodiments without a lasting, an insole (not shown) may rest on the lasting or directly on sole structure 12, in which case foot 20 is supported by both sole structure 12 and the insole.

Footwear 10 has a lateral side 42 (shown in fig. 2), also referred to as a first side; and an inner side 44 (shown in fig. 1), also referred to as a second side. Lateral side 42 and medial side 44 extend through each of forefoot region 24, midfoot region 26, heel region 28, and ankle region 31, and correspond with opposite sides of article of footwear 10, each falling on opposite sides of a longitudinal midline of article of footwear 10, as understood by those skilled in the art. Medial side 44 is therefore considered to be opposite lateral side 42.

The upper 16 may be a variety of materials such as leather, textiles, polymers, cotton, foam, composites, and the like. The front portion 16A may include a main body 30 of a material having greater elasticity, greater breathability, or both greater elasticity and greater breathability than the material or materials of the rear portion 16B to aid in foot insertion and comfort. The posterior portion 16B may be one or more materials that are stiffer than the body 30 of the anterior portion 16A to provide stability in the heel region 28. For example, the front portion 16A may be a polymeric material capable of providing elasticity, and may be a braided structure, a knitted (e.g., warp-knitted) structure, or a woven structure.

The fastening system 22 includes a strap 40 and cables and fasteners, as described herein. Strap 40 has a distal end 52 that is releasably secured to medial side 44 of front portion 16A of upper 16 via fastener 54 with a single pressing motion of distal end 52 toward front portion 16A, and is released from medial side 44 of front portion 16A via a single peeling motion away from upper 16. When the rear portion 16B is in the entry position, the fastening system 22 provides an adjustable, secure fit to tighten the body 30 of the front portion 16A around the foot 20, thereby securing the foot 20 relative to the sole structure 12 beneath the upper 16. As shown in fig. 4 and 9, when strap 40 is held outward from upper 16, distal end 52 of strap is farther from upper 16 than proximal end 72 of strap 40. As used herein, an "end" of a component is not limited to a terminal edge of the component, but also includes a portion of the component near the terminal end.

Referring to fig. 2-4, the tightening system 22 also includes a first plurality of tensioning cables 56. The tensioning cable 56 has a proximal end 58, the proximal end 58 being secured to at least one of the front portion 16A or the sole structure 12 on the lateral side 42 near the bite line 50. The tensioning cables 56 are either disposed within the body 30 of the front portion 16A near the proximal end 58, or at least within the outer surface 60 of the front portion 16A, until they emerge from the upper portion 16 at the aperture 62 of the front portion 16A, with the tensioning cables 56 extending out of the front portion 16A. For example, the tensioning cables 56 may be disposed between inner and outer layers of the front portion 16A, may extend through, or may be disposed in a channel integrally woven into the front portion 16A or secured to the front portion 16A. The fixation of the proximal ends 58 and the spacing of the holes 62 ensure that the portions of the tensioning cables 56 between the proximal ends 58 and the holes 62 of adjacent tensioning cables do not overlap and are spaced apart from each other.

The fastening system 22 also includes a plurality of looped cables 64, best shown in fig. 1 and 3. The looped cable 64 has a proximal end 66, and the proximal end 66 is secured to at least one of the front portion 16A of the upper 16 or the sole structure 12 on the medial side 44 near the bite line 50. A plurality of tensioning cables 56 extend upwardly from the proximal end 58 along the side 42 of the front portion 16A, and a plurality of looped cables 64 extend upwardly from the proximal end 66 on the inner side 44 of the front portion 16A.

Similar to the tensioning cables 56, the looped cables 64 are disposed within the anterior portion 16A near the proximal end 66, or at least inside the outer surface 60 of the anterior portion 16A, until they emerge from the aperture 68 in the upper portion 16, with the looped ends 70 of the looped cables 64 extending out of the anterior portion 16A, as best shown in FIG. 3. The looped cable 64 can be disposed between the inner and outer layers of the body 30 of the front portion 16A, or can be disposed in a channel integrally woven or otherwise secured into the front portion 16A. The fixation of the proximal end 66 and the spacing of the holes 68 ensure that the portions of adjacent ones of the looped cables 64 between the proximal end 66 and the holes 68 do not overlap and are spaced apart from each other. The looped end 70 may be a continuous loop of looped cable 64 with both cable terminations at the proximal end 66. Alternatively, the looped end 70 may be implemented by stitching or tying two portions of the cable 64 to one another to form a loop, or by any other manner of forming a hole in the end of the cable 64.

As used herein, a "cable" such as any of the tensioning cables 56 or the looped-cables 64 is a flexible, elongated tensile element, and is a structure capable of withstanding tensile loads, and includes, but is not limited to, laces, strands, wires, cords, strings, or the like. The cables 56, 64 may be positioned to (a) resist stretching of the upper 16 in a particular direction or position, (b) limit excessive movement of the foot relative to the sole structure 12 and the upper 16, (c) ensure that the foot remains properly positioned relative to the sole structure 12 and the upper 16, and/or (d) reinforce the location of force concentrations. By way of non-limiting example, suitable materials for the cables 56, 64 include various filaments, fibers, yarns, threads, or cords formed from rayon, polyamide, polyester, polyacrylate, silk, cotton, carbon, glass, aramid fibers (e.g., para-aramid fibers and meta-aramid fibers), ultra-high molecular weight polyethylene, liquid crystal polymers, copper, aluminum, or steel.

With continued reference to fig. 3, the plurality of tensioning cables 56 extend through the plurality of looped cables 64 between the proximal ends 58 of the plurality of tensioning cables 56 and the distal ends 71 (shown in fig. 2 and 4) of the cables 56 secured to the proximal end 72 of the band 40. As shown in FIG. 1, when securing the distal end 52 of the band 40 to the anterior portion 16A, the plurality of tensioning cables 56 turn at the plurality of looped cables 64, doubling toward the lateral side 42 from which they originate.

Multiple tensioning cables 56 may be passed together from their proximal ends 58 through the same hole 62 and then through the same looped cable 64. For example, as best shown in FIG. 3, two tensioning cables 56, shown as 56A, 56B in FIG. 3, extend in parallel from the proximal end 58 to the bore 62 and contact each other and then extend out of the bore 62. In other words, a pair of tensioning cables 56 extend from each hole 62, and as described herein, the pair of cables are routed together. By providing a pair in each bore 62, greater tension can be applied and any friction or wear that may occur as the cable 56 slides over the looped cable 64 during adjustment is distributed over the surfaces of both cables 56 of the pair. As used herein, an "adjacent" one of the tensioning cables 56 is a tensioning cable 56 extending from an adjacent aperture 62, or a looped cable 64 extending from an adjacent aperture 68, rather than a cable extending from the same aperture. For example, two or more tensioning cables 56 may extend out of each aperture 62. Similarly, two or more looped cables 64 may extend from each aperture 68, with the tensioning cable 56 (or a pair of tensioning cables exiting the same aperture 62) extending through each such looped cable 64 extending from the same aperture 68.

The band 40 has a proximal end 72 connected to the distal ends 71 of the plurality of tensioning cables 56. The webbed spacer 80 is secured to the plurality of tensioning cables 56 between the band 40 and the looped cable 64. The plurality of tensioning cables 56 extend through the plurality of annular cables 64 between the proximal ends 58 of the plurality of tensioning cables 56 and the webbed spacer 80. The webbed spacer 80 includes a ribbon 82 extending between adjacent ones of the plurality of tensioning cables 56, and adjacent ones of the plurality of tensioning cables 56 are spaced from one another by the ribbon 82 of the webbed spacer 80. Thus, the webbed spacer 80 helps to keep even the exposed portions of adjacent ones of the tensioning cables 56 separated from each other between the looped cable 64 and the band 40, at least when the band 40 is in the secured position of FIG. 1. The webbed spacer 80 also helps prevent tangling of the tensioning cables 56 by separating adjacent ones of the tensioning cables 56 from one another. The placement of the hole 62 and the looped cable 64 and the webbed spacer 80 work together to separate adjacent ones of the tensioning cables 56 between the hole 62 and the band 40. In addition to preventing adjacent tensioning cables 56 from tangling, this helps to maintain the resulting uniform tension distribution on the cables 56, and uniform pressure distribution on the foot, such as the instep, that tightens the body 30 in the area of the cables 56, 64.

The webbed spacer 80 may be a flexible polymer material. For example, the webbed spacer 80 may be an elastic (i.e., stretchable) inner and outer film layer 80A, 80B, which may be referred to as a skin. Non-limiting examples of materials for the webbed spacer 80 include stretchable thermoplastic polyurethane, or relatively thin orTextile materials, or composites comprising these materials, or others comprising stretchable synthetic materialsA relatively thin, flexible material. This material makes the webbed spacer 80 relatively thin and flat and able to conform to the shape of the outer surface 60 of the main body 30 of the front portion 16A against which it abuts when the distal end 52 of the band 40 is secured to the front portion 16A as shown in FIGS. 1 and 2.

The inner layer 80A is shown in fig. 4, while the outer layer 80B is shown in fig. 2. To attach the webbed spacer 80 to the tensioning cables 56, the tensioning cables 56 are placed between the inner and outer layers 80A, 80B depending on the desired spacing of adjacent tensioning cables 56. A hot melt film or other adhesive is also placed between the layers 80A, 80B and the inner and outer layers 80A, 80B are then bonded together by a flat hot pressing process. Thus, the portion of the tensioning cable 56 at the webbed spacer 80 is completely covered by the layers 80A, 80B, is secured to the layers 80A, 80B and sandwiched between the layers 80A, 80B, and is secured relative to the webbed spacer 80 so that they do not slide within the webbed spacer 80.

As best shown in fig. 2 and 4, the webbed spacer 80 is quadrilateral in shape and may have rounded or angled corners. None of the four sides of the webbed spacer 80 are parallel to each other. The distal edge 83 of the webbed spacer 80 is shorter than the proximal edge 85 of the webbed spacer 80. The width of the webbed spacer 80 tapers from the proximal edge 85 to the distal edge 83. In accordance with the tapering of the band spacer 80, the respective spacing between each respective adjacent pair of tensioning cables 56, and the respective bands 82 between each such pair, decreases along the band spacer 80 toward the band 40 (i.e., from the proximal edge 85 to the distal edge 83). As shown in FIG. 3, the proximal edge 85 has a width that is narrower than the distance from the last of the looped cables 64 to the forward-most of the looped cables 64. Thus, the webbed spacer 80 is tapered to help gradually bring adjacent tensioning cables 56 closer to each other and route the tensioning cables 56 from the more widely spaced looped cables 64 to the distal ends 71 at the narrower bands 40.

When securing the distal end 52 of the band 40 to the inner side 44 of the front portion 16A (as shown in FIG. 3), the webbed spacer 80 is disposed and rests against the outer side 42 of the front portion 16A, with the plurality of tensioning cables 56 turned at the plurality of looped cables 64. Because the webbed spacer 80 rests against the outer side 42 of the front portion 16A when the band 40 is secured in this manner, the webbed spacer 80 may help prevent the tensioning cable 56 from wearing under the force against the outer side 42, relative to embodiments without a webbed spacer.

As discussed further herein, fasteners 54 are provided on strap 40 and on upper 16 to provide a desired combination of support on both medial side 44 and lateral side 42 of front portion 16A, while still enabling adjustment of the tightness and position of strap 40. More specifically, fastener 54 includes fastening portions 54A, 54A1 on strap 40 and fastening portions 54B1, 54B2 on upper 16 that cooperate to help releasably secure strap 40 to front portion 16A so that strap 40 can hold back portion 16B in the use position. For example, as shown in FIG. 4, first fastener portion 54A1 is secured to interior side 96 of strap 40 at distal end 52 of strap 40. Second fastener portion 54B1 is secured to medial side 44 of front portion 16A and second fastener portion 54B2 is secured to lateral side 42 of front portion 16A. First fastener portion 54A is configured to be secured to second fastener portion 54B 1. In the illustrated embodiment, the fasteners 54 are hook and loop fasteners, the first fastener portions 54A, 54A1 are hooks, and the second fastener portions 54B1, 54B2 are loops. Alternatively, first fastener portions 54A, 54A1 may be loops, second fastener portions 54B1, 54B2 may be hooks, some of first fastener portions 54A, 54A1 may be hooks, some may be loops, and some of second fastener portions 54B1, 54B2 may be hooks, others may be loops, or one or more of first fastener portions 54A, 54A1 may be a combination of hooks and loops, and one or more of second fastener portions 54B1, 54B2 may be a combination of hooks and loops. Still further, other types of fasteners may be used, such as snaps, buttons, and the like.

As best shown in FIG. 4, strap 40 has a plurality of first fastener portions 54A spaced along an interior side 86 of strap 40, which provides for greater variation in the positioning of strap 40 on upper 16 in the secured state of strap 40. Spacing a plurality of first fastener portions 54A along strip 40 may allow greater stretch of strip 40 between adjacent fastener portions 54A if the material of strip 40 has greater elasticity than the material of fastener portions 54A. In other words, the portion of strap 40 between adjacent fastener portions 54A or 54A1 may stretch when pulled under tension, while the portion of strap 40 that secures less elastic fastener portion 54A or 54A1 will have less stretch capability.

The front portion 16A of the upper 16 has a second fastener portion 54B2 secured to the lateral side 42 of the front portion 16A, and another second fastener portion 54B1 secured to the medial side 44 of the front portion 16A. Although not shown, one or more additional second fastener portions may be secured to the outer surface of the rear portion 16B. The strap 40 is configured to wrap around the rear of the rear portion 16B from the outer side 42 of the front portion 16A to the inner side 44 of the front portion 16A and to be secured to the second fastener portion 54B1 on the inner side 44 of the front portion 16A when the rear portion 16B is in the use position, as shown in FIGS. 1 and 2. Some of fastener portions 54A will be secured to second fastener portion 54B 2.

The rear portion 16B is movable relative to the front portion 16A between an access position (fig. 4) and a use position (fig. 1-3). As used herein, "movable" between an access position and a use position means that the rear portion 16B can be moved from one position to another. As shown in fig. 4, the rear portion 16B is at least partially rearward of the front portion 16A in both the access position and the use position. The rear portion 16B is folded downwardly and rearwardly at fold region 46 relative to the front portion 16A to an entry position to open the foot-receiving chamber 18 from the rear to enable insertion of the foot 20 in the fore-aft direction indicated by arrow A. The fold region 46 is spaced from the sole structure 12, as best shown in figure 4. Alternatively, the rear portion 16B may be folded closer to the sole structure 12 than the front portion 16A, such as at a bite line 50 between the sole structure 12 and the upper 16, to provide a greater passage from the rear portion to the foot-receiving chamber 18. When rear portion 16B is in the entry position, foot-receiving chamber 18 is exposed in a heel region of footwear 10, and when rear portion 16B is in the use position, rear portion 16B partially encloses heel region 28. The foot 20 itself may further separate the lateral and medial sides 42, 44 of the anterior segment 16A from one another along the lateral axis (i.e., in an outward direction, perpendicular to the longitudinal midline) during foot insertion, as desired, to accommodate the girth of the foot 20 and ankle.

As shown in fig. 1-2, when the posterior portion 16B is in the use position, the posterior medial edge 93 of the anterior portion 16A interfaces with the posterior portion 16B at the medial interface 84, and the posterior lateral edge 95 of the anterior portion 16A interfaces with the posterior portion 16B at the lateral interface 86. Fastener portions 54B1, 54B2 on medial side 44 and lateral side 42 of front portion 16A abut medial abutment 84 and lateral abutment 86, respectively. When rearward portion 16B is in the use position, strap 40 passes over medial abutment 84 and lateral abutment 86, and the plurality of fastener portions 54A, 54A1 of strap 40 are secured to medial fastener portion 54B1 (FIG. 1) and lateral fastener portion 54B2 (FIG. 2).

The rear portion 16B is hinged from the use position to the access position by folding back. In such embodiments, the front inner side edge 97 of the rear portion 16B is closer to the rear inner side edge 93 of the front portion 16A when the rear portion 16B is in the use position than when the rear portion 16B is in the entry position; the front lateral edge 99 of the rear portion 16A is closer to the rear lateral edge 95 of the front portion 16A when the rear portion 16B is in the use position than when the rear portion 16B is in the entry position. Depending on the girth of the foot 20 and ankle when the foot 20 is inserted into the foot-receiving chamber 18, the use position of the rear portion 16B may be slightly more forward or more rearward relative to the front portion 16A, but in all cases it is more forward than the entry position. For example, for an ankle with a shorter girth, the anterior medial edge 97 of the posterior portion 16B is anterior and medial to the posterior medial edge 93 of the anterior portion 16A when the posterior portion 16B is in the use position, and the anterior lateral edge 99 of the posterior portion 16B is anterior and medial to the posterior lateral edge 95 of the anterior portion 16A when the posterior portion 16B is in the use position. In other words, the rear portion 16B is folded slightly more forward and inward relative to the medial and lateral sides of the upper than the front portion 16A shown in FIG. 1. Conversely, for a foot 20 and ankle with greater girth, the anterior medial edge 97 of the posterior portion 16B is further posterior than the posterior medial edge 93 of the anterior portion 16A when the posterior portion 16B is in the use position, and the anterior lateral edge 99 of the posterior portion 16B is slightly posterior than the posterior lateral edge 95 of the anterior portion 16A shown in FIG. 1 when the posterior portion 16B is in the use position. In each case, the rear portion 16B is still held in the use position by the strap 40.

The anterior and posterior portions 16A, 16B may be configured to help avoid the tendency of the anterior portion 16A to collapse during insertion into the foot under forces that slightly misalign the foot with the foot-receiving chamber 18. For example, rear medial edge 93 and rear lateral edge 95 are substantially vertical and entirely in heel region 28 of footwear 10. This arrangement may provide greater resistance to crushing and collapsing of the front portion 16A than the forwardly angled rear inboard and outboard edges.

Fig. 5-12 illustrate alternative embodiments of an article of footwear 110 within the scope of the present teachings. Article of footwear 110 has many of the same features as article of footwear 10, with the configuration and function of these features being as described with respect to article of footwear 10 and being identified with the same reference numerals. Article of footwear 110 has a different arrangement of second fastener portion 154B, has a slightly different front portion 116A and a different hinged rear portion 116B, and has multiple sets of magnetic elements that provide magnetic coupling of rear portion 116B with front portion 16A when rear portion 116B is in the use position.

Article of footwear 110 has a forward portion 116A configured as a muller shoe (mule) because it includes a muller shoe portion 116C that extends around a rear portion of heel region 28 from lateral side 42 to medial side 44, as best shown in fig. 9, 11, and 12. Tether 140 couples rear portion 116B to front portion 116A. For example, tether 140 may be sewn or otherwise secured to front portion 116A at one end of tether 140 and to rear portion 116B at the other end of tether 140. The tether 140 is a flexible, elongated structure capable of withstanding tensile loads. The tether 140 may be, for example, a material such as a braided polymer. The tether 140 may include any one or more or any combination of two or more selected from the group consisting of: tapes, ropes, filaments, strands, bands, tubes, braids, strips, cables, laces, belts, twines, threads, ropes, filaments and nets. The tether 140 is inelastic or has sufficiently low elasticity such that any increase in the length of the tether 140 when under tension (i.e., stretching of the tether 140) is minimal.

The fastener portions 154B are specifically placed on the front and rear portions 116A, 116B to help retain the rear portion 116B in the use position. As best shown in fig. 5 and 6, in the use position, the rear inboard edge 93 of the forward portion 116A interfaces with the front inboard edge 97 of the rearward portion 116B at the inboard interface 84, and the rear outboard edge 95 of the forward portion 116A interfaces with the front outboard edge 99 of the rearward portion 116B at the outboard interface 86. However, the front inboard edge 97 and the front outboard edge 99 of the rear portion 116B are spaced apart from the rear inboard edge 93 and the rear outboard edge 95 of the front portion 116A in the entry position, as best shown in fig. 9.

The plurality of fastener portions 154B of the upper include: a forward medial fastener portion 154B1 and a rearward medial fastener portion 154B2, both of which abut the medial abutment 84 (see FIG. 5) when the rearward portion 116B is in the use position; and further includes a forward lateral fastener portion 154B3 and a rearward lateral fastener portion 154B4, both of which are contiguous with the lateral abutment 86 (see fig. 6) when the rear portion 116B is in the use position. When rear portion 116B is in the use position, strap 40 passes over medial abutment 84 and lateral abutment 86, and a plurality of fastener portions 54A (best shown in FIG. 9) of strap 40 are secured to forward medial fastener portion 154B1, rear medial fastener portion 154B2, forward lateral fastener portion 154B3, and rear lateral fastener portion 154B 4. Additional fastener portions 154B5 and 154B6 are further forward on front portion 116A, and fastener portion 54A is also secured to these portions.

In addition to the strap 40 mechanically coupling the rear portion 116B to the front portion 116A in the use position, the rear portion 116B is also magnetically coupled to the front portion 116A when in the use position. More specifically, article of footwear 110 includes a front medial group of magnetic elements 90A (see FIG. 10) secured in front portion 116A near rear medial edge 93 at medial side 44 of front portion 116A and a rear medial group of magnetic elements 90B (see FIG. 9) secured in rear portion 116B near front medial edge 97 at the medial side of rear portion 116B. The anterolateral group of magnetic elements 92A is secured within the anterior portion 116A near the posterior lateral edge 95 at the lateral side 42 of the anterior portion 116A (see fig. 10), and the posterolateral group of magnetic elements 92B is secured within the posterior portion 116B near the anterior lateral edge 99 at the lateral side of the posterior portion 116B. The magnetic elements may be stitched or otherwise secured within the respective portions 116A, 116B. Although four magnetic elements are shown within each group 90A, 90B, 92A, 92B, each group may have only one magnet, or may have any different number of magnetic elements. The magnetic elements 90A, 92A, 90B, 92B have or are attracted to magnetic energy (i.e., are of ferrous material or of magnetic material in any combination) such that the magnetic element 90A is attracted to the magnetic element 90B and the magnetic element 92A is attracted to the magnetic element 92B.

In the use position, the rear portion 116B is secured to the front portion 116A at least in part by magnetic coupling of the front inboard group of magnetic elements 90A to the rear inboard group of magnetic elements 90B across the inboard interface 84 and by magnetic coupling of the front outboard group of magnetic elements 92A to the rear outboard group of magnetic elements 92B across the outboard interface 86. Each set of magnetic elements 90A, 90B, 92A, 92B may be disposed within a receptacle inserted into a respective portion 116A, 116B of upper 116, or may be inserted without a receptacle. Each set of magnetic elements 90A, 90B, 92A, 92B, and any receptacle for each set of magnetic elements, may help provide greater support to the foot in heel region 28 at medial and lateral sides 44, 42 when rear portion 116B is in the use position, particularly when medial and lateral abutments 84, 86 are substantially vertical and completely in heel region 28 of article of footwear 110, as shown in fig. 5-6. As discussed with respect to article of footwear 10, the substantially vertical orientation of rear medial edge 93 and rear lateral edge 95 of front portion 116A may help prevent collapse of front portion 116A when foot 20 is misaligned with foot-receiving chamber 18 during foot insertion. The sets of magnetic elements 90A, 92A and any receptacle in which they may reside because they are disposed near edges 93, 95, which will also help to maintain edges 93, 95 in a vertical orientation during foot insertion to help maintain the foot-receiving chamber 18 open at the heel region 28 during foot insertion.

While the magnetic element is selected to have sufficient magnetic strength to help pull the rear portion 116B to the use position when moving the rear portion 116B to the use position and to hold the rear portion 116B in the use position during some activities, the magnetic force is also low enough to enable the rear portion 116B to return to the entry position without excessive force when the rear portion 116B needs to be pulled rearwardly to remove the footwear 110 by hand or using the opposing foot to apply a downward and rearward force on top of the rear portion 116B.

Fig. 13 illustrates an alternative embodiment of an article of footwear 210 that is similar in all respects to the article of footwear 10 of fig. 1, except that the fastener portion 54C extends along the entire outer surface of the rear portion 16B from the medial edge to the lateral edge, and extends upward from the sole structure 12 along all or substantially all of the rear portion 16B along its height. This allows for greater variation in placement of the strap 40 and/or increased securement of the strap 40 to the rear portion 16B.

Similarly, fig. 14 and 15 show an article of footwear 310 that is similar in all respects to article of footwear 110 of fig. 5, except that rear medial fastener portion 154B2 and rear lateral fastener portion 154B4 are replaced by rear fastener portion 154B7, with rear fastener portion 154B7 extending along the entire outer surface of rear portion 116B from the front medial edge 97 to the front lateral edge 99 of rear portion 116B, and along all or substantially all of rear portion 116B along its height from its lower edge 301 to its upper edge 302, and over tether 140.

Fig. 16-20 show an article of footwear 410 that is similar in all respects to article of footwear 210, except that article of footwear 410 also includes a medial flap 443 secured to medial sidewall 45 of sole structure 12 and extending upward along medial side 44 of upper 16 in midfoot region 26 of article of footwear 410. Alternatively, the medial flap 443 can be secured between the upper 16 and the sole structure 12 at the bite line 50. In either example, the inboard tab 443 is secured at the inboard sidewall 45. The medial flap 443 is thicker and less resilient than the body 30, although it is flexible enough to generally conform to the outer contour of the foot within the foot-receiving cavity 18. By anchoring the medial flap 443 to the sidewall 45, the foot in the foot-receiving chamber 18 may be more securely held in place relative to the sole structure 12 under lateral forces, such as during a cutting motion.

As previously discussed, the looped cable 64 extends through the body 30 of the upper 16 and out through the aperture 68. The tensioning cable 56 extends through the upper 16, 30 on the lateral side 42 and out the aperture 62, as previously described. The webbed spacer 480 is secured to the tension cable between the looped cable 64 and the distal end 71 secured to the band 40. The webbed spacer 480 is slightly larger than the webbed spacer 80 of fig. 2, but otherwise has some of the same functions and features. The inner fin 443 may be secured to the proximal end of the webbed spacer 480. A webbed spacer 480 extends between adjacent ones of the plurality of tensioning cables 56 such that adjacent ones of the plurality of tensioning cables 56 are spaced apart from one another by the webbed spacer 480. As shown in FIGS. 16 and 17, when the distal end 52 of the strap 40 is secured to the upper 16, the webbed spacer 480 abuts the lateral side 42 of the front portion 16A of the upper 16.

When securing the strap 40 to the upper 16, the medial flap 443 is placed against the outer surface 60 of the upper 16 and covers at least some of the plurality of looped cables 64. In fig. 20, the inboard tab 443 is shown slightly spaced from the outer surface 60 so as to show that it is not secured to the outer surface 60 or the body 30. In addition, the strap 40 is shown raised to better depict the components. However, when the strap 40 is secured as shown in fig. 16, the inner flap 443 rests against the outer surface 60. As discussed above, the stiffer, less elastic nature of the medial flap 443 provides support to the medial side of the foot, particularly at the arch, when the strap 40 is tightened and secured to the upper 16.

As best shown in fig. 16, medial flap 443 is configured with a first portion 443A that extends rearward and upward from sole structure 12 and a second portion 443B that extends forward and upward from sole structure 12 and is at least partially rearward of first portion 443A at the sole structure.

Fig. 21-23 show another embodiment of an article of footwear 510 having many of the same features that function in the same manner as the article of footwear 10, including the webbed spacer 80, the band 40, the tensioning cable 56, and the looped cable 64. The upper 516 is depicted as being unitary, rather than having a front portion and a hinged rear portion. The heel portion of the upper 516 includes one or more fastener portions 554 to which the fastener portions 54A, 54A1 of the strap 40 are secured. Fastener portion 554 shown in FIG. 21 may extend around the rear of upper 516 to lateral side 42. In alternative embodiments, upper 16 may be used in article of footwear 510.

A two-piece medial flap 553 is included in article of footwear 510. For example, the inner flap 553 includes an outer inner flap 553A through which the circumferential cable 64 extends. In other words, looped cable 64 extends through outer medial flap 553A rather than through upper 516. Outer medial flap 553A is secured to medial sidewall 45 of sole structure 12 and extends upward along medial side 44 of upper 516 in midfoot region 26 of article of footwear 510. Alternatively, medial flap 553A may be secured between upper 516 and sole structure 12 at bite line 50. In either example, inboard tab 553A is referred to as being secured at inboard sidewall 45. The inner flap 553 further includes an inner flap 553B, the inner flap 553B being secured to the inner side 44 of the upper 516 and disposed between the upper 516 and the outer inner flap 553A. The inner flap 553A extends downward along only a portion of the inner side 44 and cannot move relative to the inner side 44 when the strap 40 is tensioned as does the outer inner flap 553A.

Neither the inner flap 553B nor the outer inner flap 553B is secured to the proximal end of the webbed spacer 480. The tension of the tensioning cable 56 pulls the medial side 44 of the upper 516 up and against the foot in the foot-receiving chamber 18 due to the inner medial flap 553A. Outer and inner medial flaps 553A, 553B are thicker and less resilient than the body of upper 516, although flexible enough to generally conform to the outer contour of the foot within foot-receiving chamber 18.

The annular cable 64 extends from the inner inboard flap 553B to the outer inboard flap 553A. As best shown in fig. 23, the looped cable 64 is disposed between the inner and outer layers of each of the outer inner flap 553A and the inner flap 553B or may extend through or be disposed in a channel integrally woven or otherwise secured to the outer inner flap 553A and the inner flap 553B.

As shown in fig. 21-22, the article of footwear 510 also includes a lateral flap 555 secured to the lateral side 42 of the sole structure 12 and extending upward along the lateral side 42 of the upper 516 in the midfoot region 26 of the article of footwear 510. Doll minor side flap 555 is shown secured to lateral sidewall 47 of sole structure 12, but may alternatively be secured between upper 516 and sole structure 12 at bite line 50. In either case, the outboard flap 555 is said to be secured at the outboard sidewall 47. Each of a plurality of tensioning cables can be secured to the outer flap 555 and extend outwardly from the free edge 561 of the outer flap 555. As best shown in fig. 22, the tensioning cables 56 extend through the outer flap 555 in any of the same manners as the looped cables 64 extend through the outer inner flap 553A. Strap 40 is pulled to tension tensioning cable 56, thereby pulling outside flap 555 against upper 516 and inside flap 553B against upper 516. Lateral flap 555 is secured to lateral sidewall 47, but does not secure upper 516, and is shown slightly displaced from upper 516 in FIG. 22. However, when the tensioning cable 56 is pulled tight, the outer flap 555 abuts the outer surface 60 of the upper 516.

Fig. 24-26 illustrate another embodiment of an article of footwear 610 that has many of the same features as article of footwear 10. Article of footwear 610 includes an upper 616 secured to sole structure 12. Upper 616 has a forward portion 616A and a rear portion 616B, forward portion 616A being secured to at least a forefoot portion of sole structure 12, and rear portion 616B being operatively secured to sole structure 12 at least partially rearward of forward portion 616A and articulated from an entry position (fig. 25) to a use position (fig. 24). When rear portion 616B is in the entry position, foot-receiving chamber 18 is exposed at heel region 28 of footwear 610, and when rear portion 616B is in the use position, rear portion 616B partially encloses heel region 28. As shown in FIG. 24, the belt 40 is configured to wrap behind the rear portion 616B from the outer side 42 of the front portion 616A to the inner side 44 of the front portion 616A. As best shown in fig. 24, the rear portion 616B is of sufficient size to wrap outside the front portion 616A when in the use position. The rear portion 616B has fastener portions 654D on the inner and outer sides of an inner surface 662 (also referred to as the interior side) of the rear portion 616B that are configured to be secured to the fastener portions 654E on the inner and outer sides of the outer surface 60 of the front portion 616A when the rear portion 616B is moved to the use position. Although only partially shown in the drawings, fastener portions 654E and 654D are symmetrically disposed on the medial and lateral sides of footwear 610. Fastener portions 54, 54A on strap 40 are secured to fastener portion 654F disposed on the outer surface of rear portion 616B.

The article of footwear 610 includes a medial flap 653 having an outer medial flap 653A and an inner medial flap 653B. The outer medial flap 653A is secured to the medial sidewall 45 of the sole structure 12 and extends upward in the midfoot region 26 of the article of footwear 610. Alternatively, the outer medial flap 653A can be secured between the upper 616 and the sole structure 12 at the bite line 50. In either example, the outer inner flap 653A is made to be secured at the inner sidewall 45. Inner medial flap 653B is disposed between upper 616 and outer medial flap 653A. Interior medial flap 653B is secured to foot-facing surface 17 of sole structure 12 inward of medial perimeter 12A of foot-facing surface 17. As used herein, if the inner medial flap 653B is secured directly to the foot-facing surface 17, or if it is secured indirectly to the foot-facing surface 17, the inner medial flap 653B is considered to be secured to the foot-facing surface 17, such as by being secured to a lasting covering the foot-facing surface 17 and other components that are not movable relative to the foot-facing surface 17. In the illustrated embodiment, inner flap 653B is stitched to midsole 32 at stitch 621 at foot-facing surface 17. The stitch 621 may also extend through the front portion 616A. Although the front portion 616A is shown as having an inner perimeter 616C and an outer perimeter 616D, the front portion 616A may be configured as a sock at the location where the cross-section is taken.

The inner medial flap 653B is secured to the foot-facing surface 17 between the medial and lateral perimeters 12A and 12B, but not at the medial perimeter 12A. In other words, the inner medial flap 653B is secured to the foot-facing surface 17 inside the medial perimeter 12A. The position at which the inner medial flap 653B is secured to the foot-facing surface 17 can be customized based on foot pressure data to correspond to the configuration of the wearer's arch (i.e., high arch, low arch, etc.). Alternatively, in an off-the-shelf version, the inner medial flap 653B may be positioned to correspond with the arch structure of the average wearer. In a non-limiting example, the interior medial flap 653B can be secured to the foot-facing surface 17 at a location that is at least 30% of the lateral width W2 of the sole structure 12 from the medial perimeter 12A toward the lateral perimeter 12B. Thus, the distance W1 from the inner perimeter 12A to the seam 621 is at least thirty percent of the total width W2 from the inner perimeter 12A to the outer perimeter 12B.

The inner inside flap 653B is secured to the front portion 616A only at the seam 621. In the figures, the inner flap 653B is slightly spaced from the front portion 616A to indicate that it is not otherwise fixed to the front portion 616A and can move relative to the front portion 616A. In use, the foot is in the foot-receiving cavity 18 and when the strap 40 is tightened as shown in fig. 24, the inner medial flap 653B bears against the outer surface 60 of the front portion 16A, lifting and supporting the arch of the foot.

Similar to the article of footwear 510, the looped cable 64 extends up the medial side 44 of the footwear 610 and extends from the inner medial flap 653B to the outer medial flap 653A and connects the inner medial flap 653B to the outer medial flap 653A at the free ends of the flaps 653A, 653B.

Article of footwear 610 also includes lateral flap 655 secured to lateral sidewall 47 of sole structure 12 and extending upward along lateral side 42 of the upper in midfoot region 26 of article of footwear 610. In fig. 26, outboard flap 655 is spaced slightly from front portion 616A to indicate that it is not secured to front portion 616A and is movable relative to front portion 616A. In use, the foot is in foot-receiving cavity 18 and lateral flap 655 abuts outer surface 60 of front portion 16A.

As best shown in fig. 26, the outboard flap 655 has an inner layer 655B and an outer layer 655A, and the tensioning cables 56 extend between the layers 655A, 655B. The outer and inner layers 655A, 655B are secured to each other such that the tensioning cables 56 are secured to the outer flap 655. For example, the outer layer 655A and the inner layer 655B may be adhered to one another or stitched. Thus, the portion of the tensioning cable 56 sandwiched between the outer layer 655A and the inner layer 655B does not move relative to the tab 655. Pulling the strap 40 to tension the tensioning cable 56 will thus pull the outboard flap 655 against the front portion 616A and the inboard flap 653B against the front portion 616A. In FIG. 26, the belt 40 is shown raised from the front portion 616A for clarity. The article of footwear 610 does not include a webbed spacer that overlies and is secured to the tensioning cable 56 between the upper 616 and the strap 40, but may include a webbed spacer in alternative embodiments.

As shown in fig. 25, the outer layer 655A has openings 657, which may also be referred to as windows. As best shown in fig. 24-25, at least one of the plurality of tensioning cables 56 extends across the opening 657 and is exposed at the opening 657. Each of the plurality of tensioning cables 56 may extend from a free edge 661 of outboard flap 655. The outer inner flap 653A also has a window 658, but the looped cable 64 is not shown extending across the window 658 and may terminate above the window, as shown in fig. 26.

The plurality of tensioning cables 56 extend through the plurality of looped cables 64 between the proximal ends 58 of the plurality of tensioning cables 56 and the band 40. As best shown in FIG. 26, the proximal end 72 of the strap 40 is connected to the distal ends 71 of the plurality of tensioning cables 56. The distal end 52 of the band 40 is releasably secured to the rear portion 616B, which in turn is releasably secured to the front portion 616A, as shown in fig. 24. More specifically, first fastener portion 54A is secured to fastener portion 654F on rear portion 616B. Fastener portion 654F may be referred to as a second fastener portion.
