Description

The present disclosure relates to shoes.

Conventionally, shoes such as Patent Document 1 have been proposed as shoes that can recognize the strength of pressure transmitted to various parts of the sole for each part.

Patent Document 1 describes a sole that supports the entire sole of the wearer, a plurality of lower convex portions that project downward from the lower part of the sole toward the road surface side, and are arranged at intervals from each other, and an upper portion of the sole. Disclosed is a shoe comprising a plurality of upper convex portions, each of which projects upward toward the sole side of the wearer and is arranged at a position overlapping each lower convex portion on the upper side of the sole. The plurality of lower protrusions and the plurality of upper protrusions are arranged over the entire sole in bottom view and plan view.

JP-A-2019-63491

In the shoes of Patent Document 1, the reaction force received from the road surface is transmitted to a plurality of lower convex portions, and the reaction force is directly transmitted from each lower convex portion through each upper convex portion to the sole of the wearer. Is transmitted to. As a result, the wearer can recognize the strength of the pressure transmitted to each part of the sole for each part of the sole.

By the way, when the wearer starts to move and performs an action such as turning back, a load is likely to be applied to a position corresponding to the forefoot portion of the wearer's foot on the sole of the shoe. Therefore, when the above operation is performed, it is important to concentrate the pressure transmitted from the lower convex portion and the upper convex portion on the forefoot portion of the wearer's foot.

However, in the shoe of Patent Document 1, since the plurality of lower convex portions and the plurality of upper convex portions are arranged over the entire area of the sole, the pressure transmitted from the plurality of lower convex portions and the plurality of upper convex portions is transmitted. , Disperses over the entire sole of the wearer. That is, in the above shoes, it is difficult to concentrate the pressure on the forefoot portion of the wearer's foot.

The present disclosure has been made in view of these points, and an object thereof is to relatively increase the feeling of pressure on the forefoot portion of the wearer's foot.

To achieve the above objectives, the first disclosure relates to a shoe, the shoe being provided on the sole, an upper provided on the sole and covering the wearer's foot, and at least one provided on the upper. It has a support. The sole is located on the sole at least corresponding to the forefoot of the wearer's foot, with a plurality of lower protrusions, each protruding downwards of the sole, and at least the forefoot of the wearer's foot on the sole. It has a plurality of upper convex portions, each of which projects toward the upper side of the sole and is paired up and down so as to overlap each of the plurality of lower convex portions in a cross-sectional view. The support is arranged in an internal space surrounded by the upper, and includes a sole mounting portion that extends from the inner instep side to the outer instep side of the wearer's foot with respect to the upper in the foot width direction. The sole mounting portion is configured to mount the sole located near the metatarsal base of the wearer's foot, and the metatarsal base of the wearer's foot is above the sole. It is characterized in that it is configured to be lifted toward.

In the first disclosure, each lower convex portion and each upper convex portion are paired up and down so as to overlap each other in a cross-sectional view. According to this configuration, the reaction force received from the road surface is transmitted to the plurality of lower convex portions, and the reaction force is directly transmitted from each lower convex portion to the sole of the wearer via each upper convex portion. Be transmitted. As a result, the wearer can recognize the strength of the pressure transmitted to each part of the sole of the foot for each part. The sole mounting portion of the support is configured to lift the metatarsal base of the wearer's foot upward with respect to the sole. According to this configuration, an upward force acts on the base of the metatarsal bone of the wearer's foot so that the wearer's foot floats upward from the sole. As a result, it becomes difficult for pressure to be transmitted to the base of the metatarsal bone of the wearer's foot. On the other hand, in the forefoot portion of the wearer's foot, a reaction force with respect to the above-mentioned action of the sole mounting portion is generated. That is, a downward (gravitational direction) force is generated on the forefoot portion of the wearer's foot as the reaction force. This makes it easier for the wearer's weight to be applied to the forefoot portion of the wearer's foot. As a result, pressure tends to be concentrated on the sole of the forefoot of the wearer's foot. In particular, the sole of the forefoot portion of the wearer's foot is susceptible to pressure from the lower convex portion and the upper convex portion. Therefore, when an action such as starting to move and / or turning back is performed, the pressure transmitted from the lower convex portion and the upper convex portion to the forefoot portion of the wearer's foot is applied to a portion other than the forefoot portion of the wearer's foot. It is possible to increase more than. Therefore, in the first disclosure, the feeling of pressure on the forefoot portion of the wearer's foot can be relatively enhanced.

The second disclosure is characterized in that, in the first disclosure, the sole mounting portion is configured so that the sole portion is maintained in a state of being separated upward from the sole when not worn. do.

In this second disclosure, pressure is less likely to be transmitted to the sole of the metatarsal bone of the wearer's foot, while pressure is more likely to be concentrated on the sole of the forefoot of the wearer's foot. Therefore, the feeling of pressure on the forefoot portion of the wearer's foot can be further enhanced.

The third disclosure, in the first or second disclosure, is characterized in that the sole resting portion is made of an elastically deformable material.

In this third disclosure, the sole resting portion can be elastically deformed so that the metatarsal bone sole portion of the wearer's foot floats upward from the sole. This makes it difficult for pressure to be transmitted to the sole of the metatarsal bone of the wearer's foot, while making it easier to concentrate the pressure on the sole of the forefoot of the wearer's foot. As a result, it is possible to enhance the feeling of pressure on the forefoot portion of the wearer's foot.

The fourth disclosure is characterized in that, in any one of the first to third disclosures, the sole mounting portion is made of a material having a thickness of 3.0 mm or less.

In this fourth disclosure, the feeling of foreign matter on the wearer's foot with respect to the sole mounting portion is reduced. Therefore, it is possible to prevent the wearer from being aware of the existence of the sole mounting portion. As a result, it is possible to prevent the forefoot portion of the wearer's foot from interfering with the feeling of pressure transmitted from the lower convex portion and the upper convex portion.

The fifth disclosure is characterized in that, in any one of the first to fourth disclosures, the sole mounting portion is arranged at a position corresponding to the metatarsal bone base of the wearer's foot on the sole. do.

In this fifth disclosure, it is possible to apply an upward force by the sole mounting portion directly to the metatarsal bone base of the wearer's foot. This makes it difficult for pressure to be transmitted to the sole of the metatarsal bone of the wearer's foot, while making it easier to concentrate the pressure on the sole of the forefoot of the wearer's foot. Therefore, the feeling of pressure on the forefoot portion of the wearer's foot can be further enhanced.

In the sixth disclosure, in any one of the first to fourth disclosures, a plurality of supports are provided. The plurality of supports are characterized in that each sole mounting portion is arranged so as to straddle the position corresponding to the metatarsal bone sole of the wearer's foot in the foot length direction on the sole.

In this sixth disclosure, each sole mounting portion of the plurality of supports allows the metatarsal sole of the wearer's foot to be lifted upward with respect to the sole. As a result, an upward force acts on the base of the metatarsal bone of the wearer's foot. This allows the bottom of the metatarsal bone of the wearer's foot to float upward from the sole. As a result, the feeling of pressure on the forefoot portion of the wearer's foot can be relatively increased.

The seventh disclosure further includes an adjustment unit provided on the upper in any one of the first to sixth disclosures. The support further includes a pair of connecting portions provided at both ends of the sole mounting portion. The pair of connecting portions is characterized in that at least one of them is connected to the adjusting portion.

In the seventh disclosure, by appropriately adjusting the fastening state of the shoelaces, it becomes easy to stabilize the position of the sole mounting portion at a predetermined position in the internal space surrounded by the upper. As a result, the pressure generated by the lower convex portion and the upper convex portion can be appropriately transmitted to the forefoot portion of the wearer's foot.

Eighth disclosure, in any one of the first to sixth disclosures, the support further includes a pair of connecting portions provided at both ends of the sole mounting portion. Each of the pair of connections is configured to intersect or anchor to each of the inner and outer instep sides of the upper. The intersection position or the fixing position between the pair of connecting portions and the upper is characterized in that it is separated upward by 10 mm or more from the bottommost portion of the upper surface of the sole.

In this eighth disclosure, the sole corresponding to the position of the metatarsal sole of the wearer's foot is raised above the sole by the sole mount, regardless of the height of the arch of the wearer's foot. It will be possible to lift it toward you. As a result, the pressure generated by the lower convex portion and the upper convex portion can be appropriately transmitted to the forefoot portion of the wearer's foot.

As described above, according to the present disclosure, it is possible to relatively increase the feeling of pressure on the forefoot portion of the wearer's foot.

As shown in FIGS. 2 and 6, the upper 10 is provided with an insertion hole 17 for inserting each connecting portion 21 of the support 20 described later. Each insertion hole 17 is formed so as to penetrate the upper 10 in a substantially elliptical shape in a side view. Each insertion hole 17 is arranged on the inner instep side and the outer instep side in the upper 10. Each insertion hole 17 is arranged in the vicinity of the position corresponding to the wearer's metatarsal base MTa in the upper 10 in a lateral view.

(Support)
As shown in FIGS. 1 to 6, the shoe 1 includes a support 20 provided on the upper 10. The support 20 is arranged above the sole 2. The support 20 is arranged substantially at the center of the upper 10 in the foot length direction. Specifically, the support 20 is arranged in the vicinity of the position corresponding to the wearer's metatarsal base MTa in the upper 10. The support 20 includes a pair of connecting portions 21 and 21 and a sole mounting portion 22. In FIG. 6, in order to distinguish the sole mounting portion 22 from each connecting portion 21, dot hatching is provided only on the sole mounting portion 22.

Each connecting portion 21 is formed in a substantially band shape, for example. Each connecting portion 21 is provided at each end of the sole mounting portion 22. The connecting portions 21 and 21 are integrally formed with the sole mounting portion 22. Examples of the material of each connecting portion 21 include knitted fabric, woven fabric, non-woven fabric, synthetic leather, artificial leather, and natural leather.

In this embodiment, each connecting portion 21 is configured to intersect the upper 10. Specifically, each connecting portion 21 can be inserted into the insertion holes 17 located on the inner instep side and the outer instep side (see FIGS. 2 and 6). The position where each connecting portion 21 and the upper 10 intersect (that is, the position of the insertion hole 17) is preferably set so as to be separated from the bottommost portion of the upper surface of the sole 2 by 10 mm or more. The bottommost portion of the upper surface of the sole 2 referred to here means the apex portion of the lowest upper convex portion 8 among the plurality of upper convex portions 8, 8, ... Formed on the upper surface of the sole 2.

The end of each connecting portion 21 can be connected to the shoelace 16 (adjusting portion). For example, a substantially circular hole 23 is formed on the end side of each connecting portion 21, and each connecting portion 21 is connected to the shoelace 16 with the shoelace 16 inserted through the hole 23. (See FIGS. 1, 2, and 6).

Next, as shown in FIGS. 2 to 6, the sole mounting portion 22 is formed in a substantially band shape. The sole mounting portion 22 is preferably formed so as to be as thin as possible. Specifically, the sole mounting portion 22 is made of a material having a thickness of 3.0 mm or less. In this embodiment, examples of the material of the sole mounting portion 22 include materials that do not elastically deform, such as knitted fabric, woven fabric, non-woven fabric, synthetic leather, artificial leather, and natural leather.

The sole mounting portion 22 of the present embodiment is arranged at a position corresponding to the wearer's metatarsal sole MTa on the sole 2. The sole mounting portion 22 is in a state of being bridged to the upper 10 from the inner instep side to the outer instep side in the foot width direction by the connecting portions 21 and 21 (see FIG. 6). In such a state, the sole mounting portion 22 can mount the sole located in the vicinity of the wearer's metatarsal base MTa. The sole mounting portion 22 is configured to lift the wearer's metatarsal base MTa upward with respect to the sole 2.

The sole mounting portion 22 of the present embodiment is maintained in a state of being separated upward from the sole 2 when the wearer is not wearing the shoe 1 (hereinafter referred to as “when not worn”). Specifically, when the support 20 is not worn, the entire sole mounting portion 22 floats upward with respect to the sole 2 with two fulcrums at the intersections of the connecting portions 21 and the upper 10. It is configured in.

[Action and effect of the first embodiment]
In the shoe 1 according to the first embodiment, each lower convex portion 7 and each upper convex portion 8 are paired up and down so as to overlap each other in a cross-sectional view. According to this configuration, the reaction force received from the road surface is transmitted to the lower convex portions 7, 7, ..., And the reaction force is directly transmitted from each lower convex portion 7 through each upper convex portion 8. It is transmitted to the sole of f. As a result, the wearer can recognize the strength of the pressure transmitted to each part of the sole of the foot for each part.

The sole mounting portion 22 of the support 20 is configured to lift the wearer's metatarsal base MTa upward with respect to the sole 2. According to such a configuration, an upward force (see the upward arrow shown in FIGS. 4 and 5) acts on the metatarsal base MTa so that the metatarsal bone bottom MTa floats upward from the sole 2. As a result, it becomes difficult for pressure to be transmitted to the metatarsal base MTa. On the other hand, in the forefoot portion F of the wearer, a reaction force with respect to the action of the sole mounting portion 22 described above is generated. That is, a downward (gravitational direction) force is generated on the wearer's forefoot F as the reaction force (see the downward arrows shown in FIGS. 4 and 5). This makes it easier for the wearer's weight to be applied to the wearer's forefoot F. As a result, pressure tends to be concentrated on the sole of the wearer's forefoot F. In particular, the sole of the forefoot portion F of the wearer is susceptible to pressure from the lower convex portions 7, 7, ... And the upper convex portions 8, 8, .... Therefore, for example, when movements such as starting and / or turning back are performed, the pressure transmitted from the lower convex portions 7, 7, ... And the upper convex portions 8, 8, ... To the wearer's forefoot portion F is applied to the forefoot. It is possible to increase the height more than the parts other than the part F. Therefore, in the shoe 1 according to the first embodiment, the wearer can relatively increase the feeling of pressure on the forefoot portion F.

Further, in the shoe 1 according to the first embodiment, when not worn, the entire sole mounting portion 22 is maintained in a state of being separated upward from the sole 2. This makes it difficult for the pressure to be transmitted to the wearer's metatarsal bone base MTa, while making it easier to concentrate the pressure on the sole of the wearer's forefoot F. Therefore, the wearer's feeling of pressure on the forefoot F can be further enhanced.

The sole mounting portion 22 is made of a material having a thickness of 3.0 mm or less. As a result, the feeling of foreign matter on the wearer's foot f with respect to the sole mounting portion 22 is reduced. Therefore, it is possible to prevent the wearer from being aware of the presence of the sole mounting portion 22. As a result, it is possible to prevent the wearer's forefoot portion F from interfering with the feeling of pressure transmitted from the lower convex portions 7, 7, ... And the upper convex portions 8, 8, ....

Further, since the sole mounting portion 22 is arranged at a position corresponding to the wearer's metatarsal bone bottom MTa on the sole 2, the force upward by the sole mounting portion 22 is applied to the wearer's metatarsal foot. It is possible to act directly on the bone base MTa. This makes it difficult for the pressure to be transmitted to the wearer's metatarsal bone base MTa, while making it easier to concentrate the pressure on the sole of the wearer's forefoot F. Therefore, the wearer's feeling of pressure on the forefoot F can be further enhanced.

Further, the connecting portion 21 of the support 20 can be connected to the shoelace 16 (adjusting portion). Therefore, by appropriately adjusting the fastening state of the shoelace 16, the position of the sole mounting portion 22 can be easily stabilized at a predetermined position in the internal space surrounded by the upper 10. As a result, the pressure generated by the lower convex portions 7, 7, ... And the upper convex portions 8, 8, ... Can be appropriately transmitted to the wearer's forefoot portion F.

Further, the intersection position of the connecting portion 21 and the upper 10 is separated from the bottommost portion of the upper surface of the sole 2 by 10 mm or more upward. Therefore, the sole corresponding to the position of the metatarsal bottom MTa of the wearer can be lifted upward with respect to the sole 2 by the sole mounting portion 22 regardless of the height of the arch portion of the wearer. It will be possible. As a result, the pressure generated by the lower convex portions 7, 7, ... And the upper convex portions 8, 8, ... Can be appropriately transmitted to the wearer's forefoot portion F.

[Second Embodiment]
7 to 11 show shoes 1 according to the second embodiment of the present disclosure. In the second embodiment, the quantity and position of the support 20 are different from those in the first embodiment. The other configuration of the shoe 1 according to the second embodiment is the same as the configuration of the shoe 1 according to the first embodiment. Therefore, in the following description, the same parts as those in FIGS. 1 to 6 are designated by the same reference numerals, and detailed description thereof will be omitted.

As shown in FIGS. 7 to 11, the shoe 1 according to this embodiment includes a plurality of (two in the illustrated example) supports 20 and 20. The supports 20 and 20 are arranged so that the sole mounting portions 22 straddle the position of the sole 2 corresponding to the wearer's metatarsal base MTa in the foot length direction.

Specifically, the sole mounting portion 22 located on the anterior side in the foot length direction is arranged on the sole 2 so as to correspond to the anterior side of the metatarsal bone base MTa of the wearer's foot f. On the other hand, the sole mounting portion 22 located on the posterior side in the foot length direction is arranged on the sole 2 so as to mainly correspond to the scaphoid bone NB and the cuboid bone CB of the wearer's foot f.

As described above, in the second embodiment, the sole mounting portion 22 of the two supports 20 and 20 can lift the wearer's metatarsal base MTa upward with respect to the sole 2. It becomes. As a result, an upward force acts on the metatarsal base MTa (see the upward arrows shown in FIGS. 10 and 11). As a result, the metatarsal sole MTa floats upward from the sole 2. Therefore, even in the shoe 1 according to the second embodiment, the feeling of pressure on the forefoot portion F of the wearer can be relatively enhanced as in the first embodiment.

[Modification 1]
In each of the above embodiments, the sole mounting portion 22 is maintained in a state of being separated upward from the sole 2, but the present invention is not limited to this embodiment. For example, as in the modified example 1 shown in FIG. 12, a part of the sole mounting portion 22 may be fixed to the sole 2. Specifically, in this modified example, only the substantially central portion of the sole mounting portion 22 in the foot width direction is fixed to the insole 10a of the upper 10. That is, in the sole mounting portion 22, the inner instep side and the outer instep side end side are not fixed to the insole 10a.

Even in this modified example, by adjusting the fastening state of the shoelace 16 (adjustment portion), for example, both ends of the sole mounting portion 22 in the foot width direction are attached to the sole 2 via the respective connecting portions 21. On the other hand, it is possible to maintain the state of being separated upward. This makes it difficult for the pressure to be transmitted to the wearer's metatarsal bone base MTa, while making it possible to concentrate the pressure on the sole of the wearer's forefoot F. Therefore, even in the shoe 1 according to the modified example 1, the wearer can feel the pressure on the forefoot portion F.

[Modification 2]
In each of the above embodiments, as the material of the sole mounting portion 22, a material that does not elastically deform such as knitted fabric, woven fabric, non-woven fabric, synthetic leather, artificial leather, and natural leather is shown, but the material is not limited to such a material. For example, as in the modified example 2 shown in FIG. 13, the sole mounting portion 22 may be made of a material that can be elastically deformed. Examples of the elastically deformable material include a thermosetting polyurethane, a thermoplastic polyurethane (TPU), a resin material such as a styrene elastomer, a rubber material, and a textile material having elasticity.

In this modification, the sole mounting portion 22 can be elastically deformed so that the wearer's metatarsal base MTa floats upward from the sole 2. This makes it difficult for the pressure to be transmitted to the metatarsal bone base MTa, while making it easier to concentrate the pressure on the sole of the wearer's forefoot F. Therefore, even in the shoe 1 according to the second modification, the wearer can feel the pressure on the forefoot F, as in the first embodiment.

[Modification 3]

For example, as in the modified example 3 shown in FIG. 14, the end portions of the connecting portions 21 located on the inner instep side and the outer instep side may be fixed to the inner side surface of the upper 10. That is, in the shoe 1 according to this modification, the end portion of each connecting portion 21 is not connected to the shoelace 16 (adjusting portion). Even in this modified example, it is possible to stabilize the position of the sole mounting portion 22 in the internal space surrounded by the upper 10. As a result, pressure is properly transmitted to the wearer's forefoot F.

Further, it is preferable that the fixing position between each connecting portion 21 and the upper 10 is 10 mm or more upward from the sole 2. As a result, the sole corresponding to the position of the metatarsal bottom MTa of the wearer can be lifted upward with respect to the sole 2 by the sole mounting portion 22 regardless of the height of the arch portion of the wearer. It will be possible.

[Modification example 4]
Further, in each of the above-described embodiments and the above-mentioned modification 2, each connecting portion 21 is crossed with respect to the upper 10 and the end portion of each connecting portion 21 is connected to the shoelace 16 (adjusting portion). , Not limited to this form. For example, as in the modified example 4 shown in FIG. 15, only the end portion of one connecting portion 21 (the connecting portion 21 located on the inner instep side in the illustrated example) may be fixed to the inner side surface of the upper 10. That is, in the support 20 of this modified example, the entire sole mounting portion 22 has the intersection position of the connecting portion 21 and the upper 10 on the outer instep side and the fixing position of the connecting portion 21 and the upper 10 on the inner instep side. It is configured to float upward with respect to the sole 2 with these two points as fulcrums. Even with such a configuration, it is possible to stabilize the position of the sole mounting portion 22 in the internal space surrounded by the upper 10. As a result, pressure is properly transmitted to the wearer's forefoot F.
