Incidentally, in recent years, it has been desired that even inexpensive footwear such as flip-flops have health-promoting functions. In particular, in order to make the bow legs less noticeable when wearing a swimsuit such as at the beach, it is desired that flip-flops have a function to correct bow legs.

The present invention aims to meet such demands and provide footwear having a function of correcting bowlegs.

In order to achieve the above object, the present invention includes the configuration described below.

(1) A thong (e.g., thong 20) consisting of a thong (for example, thong 21) that is sandwiched between the big toe and the index finger, and a lateral thong (for example, lateral 22) that goes over the top of the foot. , a footstool (e.g., footstool 10) on which the thong is attached and the foot is placed (e.g., footstool 10);
The footrest has a heel part on which the user's heel is placed, and a missing part (for example, a missing part 10c) that is missing a part on the little finger side with respect to the forefoot part and on the toe side with respect to the heel part. Footwear characterized by having:

(2) A thong (e.g., thong 20) consisting of a thong (for example, thong 21) that is sandwiched between the big toe and the index finger, and a lateral thong (for example, lateral 22) that goes over the top of the foot; , a footstool (e.g., footstool 10) on which the thong is attached and the foot is placed (e.g., footstool 10);
The footrest includes a heel part on which the user's heel is placed, and a thinner part (for example, the footrest 15) that is thinner at a heel part on which the user's heel is placed, and a part on the little finger side with respect to the forefoot part and on the toe side with respect to the heel part. A piece of footwear characterized by having a missing portion 16a (part of the missing part 16a).

According to (1) and (2), when a user walks wearing the footwear of the present invention, the toe side and outer part of the sole of the foot is separated from the ground, so the user's weight is Concentrate on the medial side of the sole of the foot.

FIG. 1 is a perspective view showing the appearance of footwear 1 according to a first embodiment of the present invention. FIG. 2 is a front view of FIG. 1; It is a perspective view showing the appearance of footwear 2 in a modification of the first embodiment of the present invention. FIG. 3 is a perspective view showing the appearance of footwear 3 according to a second embodiment of the present invention. 5 is a front view of FIG. 4. FIG. It is a perspective view showing the appearance of footwear 3 in a modification of the second embodiment of the present invention.

Embodiments of the present invention will be described in detail below with reference to the drawings.

[First embodiment]
FIG. 1 is a perspective view showing the appearance of footwear 1 according to the first embodiment of the present invention. FIG. 2 is a front view of FIG. 1. The footwear 1 is a so-called beach sandal, and includes a footrest 10 and a thong 20. Note that FIGS. 1 and 2 show footwear 1 worn on the user's left foot, and since the footwear 1 worn on the right foot is bilaterally symmetrical with respect to the footwear 1 worn on the left foot, the footwear 1 worn on the right foot is A detailed explanation of 1 will be omitted. Also,

The footrest 10 is a flat plate-like member made of rubber material, EVA urethane material, etc. and shaped like the outer circumference of the foot, and includes a heel part 10a on which the user's heel is placed, and a toe part 10a on which the user's toes are placed. A portion 10b is provided.

The thong 20 is made of cloth or synthetic resin, and includes a front thong part 21 and a lateral thong part 22. The front part 21 is a part that extends upward from the plate surface of the footrest 10 and is held between the user's big toe and index finger, and is disposed at the toe part 10b of the footrest 10. The horizontal cord part 22 is constituted by a string-like or band-like member made of cloth or synthetic resin, and is a side part on the thumb side of the footrest 10 (hereinafter referred to as the inner side part) with the front cord part 21 as the base end. It is divided into two parts: an inner transverse part 22a extending towards the little finger side and an outer transverse part 22b extending towards the little finger side (hereinafter referred to as the outer side part). The terminal ends of the inner horizontal cord part 22a and the outer horizontal cord part 22b are respectively fixed to both sides of the non-stepping area of the footrest 10.

The footrest 10 further includes a missing part 10c on the little finger side with respect to the front part 21. The missing part 10c is made by making a cut along the longitudinal direction of the footrest 10 from the end of the footrest 10 on the toe side, passing through a part slightly closer to the little finger with respect to the frontal part 21, and ending at the end of the outer lateral part 22b. It is formed by cutting in a gentle arc shape to the outer side of the footrest 10 through a portion slightly closer to the toe.

Next, a state in which the user wears the footwear 1 will be described.

The footwear 1 configured in this manner can be worn by a user passing his or her feet through the thong 20 and pinching the thong part 21 between the user's big toe and index finger. At this time, the inner lateral part 22a passes through the base of the user's big toe, and the outer lateral part 22b passes through the instep of the user's foot, making it difficult for the footwear 1 to come off the user's foot.

When the user is wearing the footwear 1, the user's middle finger, ring finger, little finger and their bases, and the lateral head of the adductor hallucis muscle located closer to the heel with respect to the bases; The missing portion 10c faces the lateral part of the arch of the flexor digitorum brevis muscle. In other words, if the sole of the foot is divided into two parts near the arch of the foot, into the toe side and the heel side, and the toe side is further divided into the big toe side (inside) and the little finger side (outside), the outer half of the toe side is generally opposed to the missing portion 10c.

Therefore, when a user walks wearing footwear 1, the outer half of the sole of the foot on the toe side is separated from the ground, so the user's weight is concentrated on the inner side of the sole of the user's foot. . In addition, the user becomes conscious of not touching the outer part of the sole of the foot, which is opposite to the missing part 10c, on the ground when standing upright or walking. This makes it possible to correct the center of gravity of the user's legs inward, and if the user has bow legs, it becomes possible to narrow the distance between the user's knees.

According to this embodiment configured in this way, when the user wears the shoes, the user's weight is concentrated on the inner side of the sole, so it is possible to correct the center of gravity of the user's legs inward. This makes it possible to narrow the distance between the user's knees. This allows the user to walk without worrying too much about bow legs when changing into a swimsuit at the beach. According to the present embodiment, when Spiel plaster is applied to corns formed on the outside of the sole of the foot, the area to which Spiel plaster is applied can be separated from the ground by wearing the footwear 1. It can also be expected to have the effect of reducing the slippage and peeling of Spiel plaster when walking.

[Modification of the first embodiment]
FIG. 3 is a perspective view showing the appearance of footwear 2 according to a modification of the first embodiment of the present invention. Footwear 2 according to a modification of the first embodiment is obtained by further forming a missing portion 10d in which the heel portion is missing in the footrest 10 of the footwear 1 according to the first embodiment shown in FIG. This missing portion 10d can be called a heel missing portion.

According to the modified example of the first embodiment configured in this way, the footwear 2 has the missing portion 10d, so that the user looks like he or she is walking on tiptoe, and by walking while wearing the footwear 2, This allows you to naturally train the muscles from the backs of your calves and thighs to your buttocks. Furthermore, since the footwear 2 has the missing portion 10c, it is possible to correct the center of gravity of the user's legs inward as described above, and if the user has bow legs, the gap between the user's knees can be narrowed. It becomes possible to do so.

[Second embodiment]
FIG. 4 is a perspective view showing the appearance of footwear 3 according to the second embodiment of the present invention. FIG. 5 is a front view of FIG. 1. Note that the same reference numerals are omitted for the same members or members having the same function as the members in the footwear 1 shown in FIGS. 1 and 2, and detailed description thereof will be omitted.

The footwear 3 includes a footrest 15 and a thong 20. The footwear 3 differs from the footwear 1 in the first embodiment in that the footrest 10 in the first embodiment is a footrest 15.

The footrest 15 has a two-layer structure including a first layer 16 and a second layer 17. The first layer 16 has a missing portion 16a. Moreover, the first layer 16 has the same shape or a different thickness except that the corner of the toe of the footrest 10 according to the footwear 1 in the first embodiment is chamfered, and the missing part 16a is It is formed at the same location as the missing portion 10c of the footrest 10 according to the above.

The second layer 17 has a shape that resembles the outer periphery of a foot, with no missing portion 16a formed in the first layer 16. The footrest 15 is constructed by bonding the lower surface of the first layer 16 and the upper surface of the second layer 17, and a step is formed at the portion of the missing portion 16a.

The footwear 3 is completed by attaching the thong 20 to the footrest 15 in the same way as the footwear 1 in the first embodiment.

When the user wears the footwear 3, the outer part of the sole of the user's foot on the toe side faces the upper surface of the second layer 17 with a distance corresponding to the step created by the missing portion 16a.

Therefore, like the footwear 1 in the first embodiment, the footwear 3 in the second embodiment, when the user wears the footwear 1 and stands upright, the weight of the user is transferred to the inside of the sole of the user's foot. Concentrate on the sides. This makes it possible to correct the center of gravity of the user's legs inward, and if the user has bow legs, it becomes possible to narrow the distance between the user's knees. Furthermore, since the lower part of the missing portion 16a is covered by the second layer 17, when the footwear 3 is used on a sandy beach, the soles of the feet do not come into direct contact with the sand of the beach.

[Modification of second embodiment]
In the footwear 3 of the second embodiment, the first layer 16 and the second layer 17 of the footrest 15 may be reversed so that the second layer 17 is the upper layer and the first layer 16 is the lower layer.

The modified example of the second embodiment configured in this manner also provides the same effects as the footwear 3 of the second embodiment.

Also, in the footwear 3 of the second embodiment, the heel portion of the footrest 15 may be omitted, similarly to the footwear 2 of the modification of the first embodiment. This allows the user to walk on their tiptoes, allowing them to naturally train their calves and muscles from the backs of their thighs to their buttocks. Further, in the example shown in FIG. 3, the heel portion is missing in an arc shape, but it may be missing on a straight line as shown in FIG.

Further, as shown in FIGS. 3 and 6, the second layer 17 of the footwear 3 of the second embodiment is adhered to the lower surface of the footwear in which the heel part is missing in an arc shape, so that the second layer 17 is configured into two layers. Good too. This prevents the heels from coming into direct contact with the sand on the beach.

In addition, in the second embodiment and its modifications, the footrest 15 is formed in two layers, but a thin plate is formed in the part of the footrest that faces the outer side of the sole of the user's foot. It may be a single layer (single plate) as long as it has a section formed thereon.

Although the embodiments of the present invention have been described above, the embodiments of the present invention are not limited to the above-described embodiments. For example, although the above-described embodiment has been described using flip-flops as an example, it can also be applied to sandals. Further, the foot plate is made of a rubber material, an EVA urethane material, or the like, but the material of the foot plate is not limited thereto. For example, it may be made of wood.
