DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

An example of a shoe (100) in the first embodiment is shown in FIGS. 1-3. The shoe (100) has a sole (110) including a lateral edge (115) between a toe end (110A) and a heel end (110B). A first fold line (125A) is located between lateral edge (115) and medial edge (120) and spans sole (110), allowing sole (110) to fold along first fold line (125A). the

In the described solution, the sole (110) also has a second fold line (125B) between the lateral edge (115) and the medial edge (120) and across the sole. The sole (110) can be folded along the second folding line (125B). As shown in Figure 1, the first and second fold lines (125A, 125B) are inclined toward each other. the

The second fold line (125B) is located between the first fold line (125A) and the heel end (110B). Therefore, the sole (110) is divided into three parts, namely the toe part (130) formed between the first fold line (125A) and the toe end (110A), the first fold line (125A) and the second A mid portion (132) formed between the first fold line (125B) and a heel portion (135) formed between the second fold line (125B) and the heel end (HOB). The placement of the first and second folding lines (125A, 125B) should ensure that the middle portion (132) is generally located below the arch of the user's foot. the

The first and second fold lines (125A, 125B) are arranged so that the sole (110) (110) in its normally flat or wearable state (as shown in Figures 1-3) can be folded along the first and second fold lines The fold lines (125A, 125B) are folded, and the folded (as shown in Figs. 4 and 5) toe section, mid section and heel section (130, 132, 135) lie on top of each other. the

In the embodiments described above, the first and second fold lines (125A, 125B) intersect at least approximately at an apex (140), thereby giving the intermediate portion (132) a generally triangular shape. In the embodiments described above, the apex (140) is located at or near the outer edge (115). The middle part (132) forms a point at the vertex (140), but in some cases the first and second fold lines (125A, 125B) cannot meet exactly at the vertex (140), then the middle part ( 132) will have a certain width distance on the outside edge (115). the

The first angle formed between the first fold line (125A) and the tangent to the adjacent outer edge (115) at the apex (140) is the angle α, which is acute and usually between 55° and 85° between, in the first embodiment about 75°. The second angle formed between the first folding line (125A) and the second folding line (125B) is β angle, which is also an acute angle, usually between 50° and 80°, in the first implementation About 63° in the scheme. Typically, angle α is equal to or greater than angle β. In the most typical scheme, the angle α is greater than the angle β by less than 30°. Make sure that the angle α is equal to or greater than the angle β so that when the sole (110) is folded along the first fold line (125A), the second fold line (125B) will follow the toe cap formed by the outer edge (115) The circumferential area of portion (130) is extended or inboard such that mid portion (132) lies within the circumference of toe portion (130) without overhanging. As shown below and in Figures 4 and 5, when the sole (110) is folded again along the second fold line (125B), the heel portion (135) will be drawn from the outer edge (115) of the toe portion (135). Beginning proximately across toe portion (130) and extending toward medial edge (125) proximate toe end (110A). In said state, the heel part (135) will not exceed the circumference of the toe part (130) to cause an overhang phenomenon, so that the shoe (100) in the folded state appears to have a compact structure. the

As shown in Figure 2, the sole (110) comprises a bottom layer (156), a flexible middle layer (155) and a top layer (157). A flexible middle layer (155) is formed between the top layer (157) and the bottom layer (156) and extends continuously between the toe end (110A) and the heel end (110B). The middle layer (155) may be made of a durable and tear resistant flexible material such as a molded plastic material, such suitable plastic materials include polypropylene, polyurethane, nylon or other similar materials. The middle layer can also be made of elastic materials (such as thermoplastic rubber TPR). The bottom layer (156) will typically be made of a hard, wear-resistant elastic material such as rubber or thermoplastic rubber TPR, while the top layer (157) will be made of a cushioning material such as foam cushioning material, vinyl acetate (EVA) or other similar material) so as to support the user's feet and make the shoes (100) more comfortable to wear. The layers of the shoe (100) are preferably made from materials deemed suitable. The bottom layer (156), middle layer (155) and top layer (157) will be bonded together to form a multilayer structure. the

As shown in Figures 2 and 3, the top layer (157) is intermittently spaced between the toe section (130) and the middle section (132) to form a first upward indentation at the first fold line (125A) The slots (160) are also intermittent between the mid portion (132) and the heel portion (135) and form a second upper groove (161) at the second fold line (125B). The top layer ( 157 ) is thus formed from three separate modules, corresponding to the toe section ( 130 ), the middle section ( 132 ) and the heel section ( 135 ). Likewise, the bottom layer (156) is intermittently distributed between the toe portion (130) and the middle portion (132), thereby forming the first lower groove (162) at the first fold line (125A), while also A second lower groove (161) is formed intermittently between the mid portion (132) and the heel portion (135) and at the second fold line (125B). The bottom layer (156) is thus composed of three modules, corresponding to the toe part (130), middle part (132) and heel part (135). In this way, the intermediate layer (155) forms a first fold line (125A) between the first upper groove (160) and the first lower groove (162), and a second upper groove A second fold line (125B) is formed between the groove (161) and the second lower groove (163). The discontinuous distribution of the top and bottom layers (157, 156) at the first and second fold lines (125A, 125B), together with the middle layer (155) of flexible material, allows the sole (110) to conform to The three parts of the toe, the middle and the heel (130, 132, 136) are folded. The width of each depression (160, 161, 162, 163) is substantially at least twice the respective depth, which depends on the thickness of the top layer (157) or bottom layer (156) as the case may be. Thus, there will be sufficient space in the groove for the sole (110) to be folded at 180° along the radii at the first and second folding lines (125A, 125B). In the particular case where the top and bottom layers (157, 156) are both about 1.5mm thick and thus form grooves of 1.5mm depth, each groove width should be at least 3mm. the

The shoes (100) shown in Figures 1-3 are sandals or flip-flops, the upper part of which is formed by one or more shoelaces (150). These laces extend from the sole (110) and fasten the shoe (100) to the user's foot in a conventional manner. the

As shown in Figures 4 and 5, the shoe (100) in a flat or wearable state is refolded into a folded/contracted state. the

The sole (110) can be folded from a flat state to a folded state in any manner. As shown in Figure 4, the toe portion (130) is folded down along the first fold line (125A), causing the bottom layer (156) to fold over the toe portion (130) and the other bottom layer areas of the mid portion (132) . The heel portion (135) is folded upwards along the second fold line (125B) so that the top layer (157) is folded into the area of the top layer (157) between the middle portion (132) and the heel portion (135). The middle part (132) at this time becomes the intermediate layer between the toe part (130) and the heel part (135). In the fully folded state, the top layer (157) on the toe portion (130) forms one of the outer surfaces on the sole (110), while the bottom layer (156) on the heel portion (1354) forms the facing surface. The arrangement of the first and second folding lines (125A, 125B) should ensure that in the folded state, the middle part (132) and the heel part (135) respectively cover and fold with the toe part (130), and are located at Within the circumference range of the toe part (130), that is, the circumference range of the entire folded sole (110) is within the circumference range of the toe part (130) without the middle part (132) or the heel part (135) Overhang phenomenon occurs. Due to the orientation of the first and second fold lines (125A, 125B), in the folded state, the second fold line (125B) will run against the lateral edge (115) of the toe portion (130). The heel portion (135) extends toward the medial edge (125) near the toe end (110A). Through this folding method, the shoes appear compact and can be easily inserted into a shoe bag with relatively small space as shown in FIG. 10 and FIG. 11 . The shoe bag (200) includes a sealing device (210) such as a zipper or the like for closing or opening the shoe bag (200) and sealing the shoes (100) inside the shoe bag (200). The shoe bag containing the folded shoes can be placed in another small bag, handbag or similar bag so that it can be carried around and taken out for use when needed. the

As shown in Figure 5, another method of folding the sole (110) is provided, that is, the toe part (130) is folded up along the fold line (125A), and the heel part (135) is folded along the second fold line (125B). ) to fold down. In this folded state, although the bottom layer (156) at the toe portion (130) and the top layer (157) at the heel portion (135) form two opposing surfaces of the sole in the folded state, the middle portion ( 132) remains sandwiched between the toe portion (130) and the heel portion (135). The sole (110) can also have another folding method, that is, the toe part (130) and the heel part (135) are folded along the first and second folding lines (125A, 125B) and in the same direction. the

Figures 6 and 7 show another embodiment of the shoe (100'), and Figure 7 shows an exploded view of the shoe (100). The shoe (100') is substantially the same as the shoe (100) of the first embodiment, except that the middle layer (155') and the bottom layer (156') are combined (in this embodiment thermoplastic rubber TPR or polyurethane material molding), formed into an integral molded part, namely the sole body (170). The middle layer (155') portion in the sole body (170) is molded to form the upper surface, thereby forming a Upright edges (171, 172, 173). These edges enable easy and precise positioning of the three parts forming the top layer (157)

point. The shoe (100') can also be like the shoe (100) of the first embodiment described above, with first and second fold lines (125A and 125B) and associated grooves (160, 161, 162, 163) form. The same goes for the laces (150), while the sole (110') can also be formed as a molded unit from the top, middle and bottom layers.

Figures 8 and 9 show a shoe (100'') in a third embodiment. In the third embodiment, the sole (110'') of the shoe (100'') is substantially the same as the sole portion of the shoe (100'') in the first and second embodiments, but the shoe (100'' ') with close-toed shoes, in this case ballet flats or slippers, the second angle formed between the first and second fold lines (125A'' and 125B'') is approximately 73° . The upper part (152) of the shoe is usually made of a flexible fabric that extends outward around the circumference of the sole (110'') to wrap around the foot of the user wearing the shoe (100''). Shoes can also take a variety of other commonly used forms. the
