Description

Shoes

This disclosure relates to shoes.

Hallux valgus is a condition in which the base of the big toe (MP joint) protrudes and the tip bends towards the little toe, and is seen in approximately 30% of adults. When people with hallux valgus wear shoes, the base of the big toe is pressed down by the upper of the shoe, which can cause pain.

Various shoes have been proposed for people with hallux valgus. For example, Patent Document 1 proposes an orthopedic shoe intended to be worn by people suffering from conditions such as hallux valgus. The shoe has a relief area formed in the upper for the deformed area of the toes. This relief area is made of a material that is more elastic and has a lower friction coefficient than the other materials in the upper, and is configured to be stretchable.

EP1800555A1

The shoes disclosed in the above-mentioned Patent Document 1 have an extended relief area to alleviate the stress on the base of the big toe that is caused by hallux valgus.

The shoes disclosed in the above-mentioned Patent Document 1 have the relief area of the upper and other areas constructed from different materials. However, in shoes suitable for exercise (e.g., running), the upper is usually made of the same material and is required to be breathable. The above-mentioned shoes have uppers constructed from different materials and no consideration is given to breathability, so they cannot fulfill the functions required of shoes suitable for exercise (e.g., running).

As mentioned above, conventional shoes worn by people with hallux valgus are not suitable for exercise (e.g., running), and there is a demand for shoes that people with hallux valgus can wear comfortably and use while exercising.

The present disclosure has been made in consideration of the above problems, and aims to provide shoes suitable for exercise (e.g., running) that take measures against hallux valgus.

The inventors have investigated the stress caused by the base of the big toe protruding due to hallux valgus while satisfying the demands of the exercise itself (for example, running). After extensive research, the inventors have come up with the following configuration.

A shoe according to one embodiment of the present disclosure is a shoe comprising a sole and an upper provided above the sole and configured to accommodate a wearer's foot, the forefoot region of the upper covering at least the forefoot of the wearer being formed from a single continuous piece of knitted or woven fabric, the forefoot region having a first region corresponding to the medial side of the foot including the base of the wearer's big toe, a second region corresponding to the front end of the upper, and a third region located at least between the toe side of the first region and the second region, the elasticity of the first region being higher than that of the second region, and the elasticity of the third region being lower than that of the second region.

In the following description, numerous specific examples are provided to provide a thorough understanding of the present disclosure. However, it will be apparent to one skilled in the art that the present invention may be practiced without these specific examples.

The following disclosure should therefore be considered as illustrative of the present disclosure and is not intended to limit the present disclosure to the specific embodiments illustrated in the drawings or description below.

According to one embodiment of the present disclosure, the forefoot region of the upper covering at least the wearer's forefoot is formed from a single continuous piece of knitted or woven fabric, and the first region corresponding to the medial side of the foot including the base of the wearer's big toe is configured to be more elastic than the other regions, so that the first region corresponding to the protruding part of the base of the big toe deforms outward. This reduces the pressure that the wearer puts on the base of the big toe, relieving stress and reducing discomfort caused by pain for people with hallux valgus. Furthermore, because the forefoot region is formed from a single continuous piece of knitted fabric, it is possible to obtain the wearing sensation of a shoe for exercise (e.g., running).

FIG. 1 is a plan view that illustrates a schematic diagram of a foot skeletal model superimposed on a shoe according to a first embodiment of the present disclosure. FIG. 2 is a development view showing an upper body of the shoe according to the first embodiment of the present disclosure. FIG. 3 is a top view of a shoe according to the first embodiment of the present disclosure. FIG. 4 is a side view of the outer side of the shoe according to the first embodiment of the present disclosure. FIG. 5 is a side view of the medial side of the shoe according to the first embodiment of the present disclosure. FIG. 6 is a plan view of the inner surface side of the front end of the shoe according to the first embodiment of the present disclosure. FIG. 7 is a top view of the shoe according to the first embodiment of the present disclosure when worn by a wearer with hallux valgus. FIG. 8 is a plan view that illustrates a skeleton model of a foot with hallux valgus superimposed on the shoe according to the first embodiment of the present disclosure. FIG. 9 is a development view showing an upper body of a shoe according to a modified example of the first embodiment of the present disclosure.

Next, a specific description will be given based on a shoe according to an embodiment of the present disclosure. Note that the shoe according to the present disclosure is not limited to the embodiment shown below, and can be appropriately modified without departing from the gist of the present disclosure.
In the embodiments and modified examples of the present disclosure, the same or equivalent components and members are given the same reference numerals, and duplicated explanations are omitted as appropriate.

In addition, some of the members that are not important for explaining the embodiments are omitted in each drawing.

　In addition, terms including ordinal numbers such as first and second are used to describe various components, but these terms are used only for the purpose of distinguishing one component from other components, and do not limit the components.

[Embodiment]
FIG. 1 is a plan view showing a state where a foot skeleton model is superimposed on the shoe 1 according to the first embodiment of the present disclosure, FIG. 2 is a development view showing an upper body 20 of the shoe 1 according to the first embodiment of the present disclosure, FIG. 3 is a top view of the shoe 1 according to the first embodiment of the present disclosure, FIG. 4 is a side view of the outer foot side of the shoe 1 according to the first embodiment of the present disclosure, and FIG. 5 is a side view of the inner foot side of the shoe 1 according to the first embodiment of the present disclosure. Each of the drawings including FIG. 1 shows only the shoe 1 for the left foot. Since the shoe 1 for the left foot and the shoe 1 for the right foot have a symmetrical structure, the shoe 1 for the left foot will be described in this embodiment, and the description of the shoe 1 for the right foot will be omitted. In the following description, the direction in which the shoe center axis C, which is a perpendicular line passing through the center of the shoe 1 when viewed in a plane, extends is referred to as the front-rear direction, and the direction perpendicular to the front-rear direction when viewed in a plane is referred to as the foot width direction.

In addition, in the front-to-back direction, the direction from the heel to the toe of the shoe 1 is referred to as the front, and in the front-to-back direction, the direction from the toe to the heel of the shoe 1 is referred to as the rear. In the up-down direction, the direction toward the ground of the shoe 1 placed on a flat surface such as the ground is referred to as the down, and the direction away from the ground is referred to as the up.

The side of the foot that is in the anatomical orthogonal position is called the medial side of the foot, and the side opposite the median side of the foot that is in the anatomical orthogonal position is called the lateral side of the foot. In other words, the side closer to the midline in the anatomical orthogonal position is called the medial side of the foot, and the side farthest from the midline in the anatomical orthogonal position is called the lateral side of the foot.

As shown in Figure 1, the human foot is mainly composed of the cuneiform bone Ba, cuboid bone Bb, navicular bone Bc, talus Bd, calcaneus Be, metatarsal bone Bf, proximal phalangeal bone Bg, middle phalangeal bone Bh, and distal phalangeal bone Bi. The joints of the foot include the distal interphalangeal joint DIP joint Ja, the proximal interphalangeal joint PIP joint Jb, the metatarsophalangeal joint MP joint Jc, the Lisfranc joint Jd, and the Chopart joint Je.

The human foot is divided into the forefoot LF, midfoot LM, and hindfoot LR by the Lisfranc joint Jd and Chopart joint Je. The forefoot LF refers to the part of the foot located forward of the Lisfranc joint Jd. The midfoot LM refers to the part between the Lisfranc joint Jd and the Chopart joint Je. The hindfoot LR refers to the part of the foot located behind the Chopart joint Je.

As shown in Figures 1 and 2, the upper 2 comprises an upper forefoot region 20F that covers the forefoot LF of a wearer with a standard build, an upper midfoot region 20M that covers the midfoot LM of a wearer with a standard build, and an upper rearfoot region 20R that covers the rearfoot LR of a wearer with a standard build. The upper forefoot region 20F, upper midfoot region 20M, and upper rearfoot region 20R are connected in this order in the front-to-back direction of the upper 2.

The first boundary line S1 is a line along the foot width direction that passes roughly along the Lisfranc joint Jd of a wearer with a standard build, and the second boundary line S2 is a line along the foot width direction that passes roughly along the Chopart joint Je of a wearer with a standard build. The upper forefoot region 20F is the portion located forward of the first boundary line S1. The upper midfoot region 20M is the portion located between the first boundary line S1 and the second boundary line S2. The upper rearfoot region 20R is the portion located behind the second boundary line S2.

The shoe 1 according to the first embodiment will be described with reference to Figures 3 to 5.

Shoe 1 is a shoe suitable for running and other sports, and is used, for example, as a running shoe or other sports shoe. Shoe 1 includes a sole 3 and an upper 2 that is provided above the sole 3 and is configured to accommodate the wearer's foot.

The upper 2 comprises an upper body 20, a tongue 21, and shoelaces 22.

The upper body 20 covers the part of the instep of the foot. At the top of the upper body 20, there is an opening 20a for inserting the wearer's foot, and an opening 20b that opens and communicates with the opening 20a. The opening 20b is closed with a tongue piece 21. Eyelet parts 20c (20c1) that are spaced apart from each other in the front-to-rear direction are provided on both side edges of the opening 20b in the foot width direction.

The eyelet portion 20c (20c1) is not particularly limited in its configuration as long as it is possible to pass the shoelace 22 through it, but in this embodiment 1, it is a through hole that passes through the upper body 20 in the vertical direction.

The tongue 21 is a member for protecting the instep of the wearer's foot. The tongue 21 covers the opening 20b inside the upper body 20. The tongue 21 is fixed to the upper body 20 by sewing, welding, adhesion, or a combination of these.

The upper body 20 and the tongue 21 may be made of a material such as knitted fabric in which threads are rolled into a chain shape and the chain-shaped parts are hooked together to form a cloth, woven fabric in which warp and weft threads are crossed at a certain angle to form a cloth, or braided fabric in which three or more braided threads are crossed and run diagonally to form a cloth. In particular, for shoes 1 that require breathability and light weight, knitted fabric woven with woven polyester threads is used for the upper body 20 and the tongue 21. Note that the materials for the upper body 20 and the tongue 21 are not limited to the materials given as examples.

The shoelace 22 is a string-like member that is threaded alternately through the eyelet portion 20c provided on the side edge of the opening 20b on the inner foot side 200 in the foot width direction and the eyelet portion 20c provided on the side edge of the opening 20b on the outer foot side 210 in the foot width direction. The shoelace 22 is removably attached to the upper body 20.

In this embodiment 1, the upper 2 including the tongue 21 and shoelaces 22 is described as an example, but the upper 2 may have a monosock structure in which the portion corresponding to the tongue 21 is integrated with the ankle portion of the upper body 20. Also, the upper body 20 may have a structure in which a hook-and-loop fastener is used instead of the shoelaces 22 to fit the upper body 20 to the foot. When the hook-and-loop fastener is used to fit the upper body 20 to the foot, the eyelet portion 20c is not formed in the upper body 20.

The sole 3 is located below the upper 2. The sole 3 covers the sole of the foot. The sole 3 includes an outsole 30 and a midsole 31. The sole 3 is fixed to the upper body 20 by sewing, welding, adhesion, or a combination of these. The lower surface of the outsole 30 becomes the contact surface 30a that is placed on the ground. The midsole 31 is located on the upper surface of the outsole 30 and has cushioning properties. The outsole 30 may be integrated with the midsole 31. The outsole 30 integrated with the midsole 31 is also called a "unisole."

In this embodiment 1, as shown in FIG. 5, the medial side 200 of the midsole 31 of the sole 3 includes a first support portion 31a and a second support portion 32a which is the area of the midsole 31 other than the first support portion 31a. The first support portion 31a supports at least the midfoot portion LM of the wearer's medial side 200. The hardness of the first support portion 31a is configured to be higher than the hardness of the second support portion 32a. By setting the respective hardnesses in this way, the midfoot portion LM of the wearer's medial side 200 is prevented from collapsing toward the medial side.

The configuration of the upper forefoot region 20F of the upper body 20 will be described in detail with reference to Figures 2 to 5. As shown in the development view of Figure 2, the upper body 20 of this embodiment 1 is composed of the upper forefoot region 20F, the upper midfoot region 20M, and the upper rear foot region 20R, which are connected in this order in the front-to-rear direction of the upper 2. The upper body 20 is formed from a single continuous piece of knitted or woven fabric. In this embodiment 1, it is formed from a single piece of knitted fabric, for example, mesh fabric, ensuring breathability and light weight.

The upper forefoot region 20F, which covers the wearer's forefoot LF, has a first region 25 that corresponds to the side of the medial side 200 of the foot, including the MP joint Jc, which is the base of the big toe B1 (distal phalange Bi, proximal phalange Bg) (see Figure 1), a second region 26 that corresponds to the front end 20d of the upper body 20, and a third region 27 that is located at least between the toe side of the first region 25 and the second region 26.

In this embodiment 1, the upper forefoot region 20F has a fifth region 28 that includes the shoe center axis C of the upper forefoot region 20F and is located between the front end of the opening 20b and the toe guard 24, and a sixth region 29 that is located on the outer foot side 210 from the fifth region 28. Between the second region 26 and the fifth region 28, and between the fifth region 28 and the sixth region 29, regions with the same configuration as the third region 27 are located.

In this embodiment 1, the first region 25, the second region 26, the fifth region 28, and the sixth region 29 are hatched to facilitate understanding.

As shown in Figures 2 and 5, the first region 25 is formed in an area covering the side of the inner foot 200 corresponding to the position from the front end to the upper part of the rear end of the ball of the big toe, with the part corresponding to the MP joint at the base of the big toe B1 (see Figure 1) as its center. The first region 25 in this embodiment 1 is formed so that it is wide on the sole 3 side and narrows in the front-to-rear direction from the sole 3 upward. In other words, it is formed in a mountain shape extending upward from the sole 3, with the position corresponding to the MP joint as its apex.

In the present embodiment 1, the first region 25 is formed in a mountain shape, but it is not limited to this shape and may be an elliptical or rectangular shape, as long as it covers the area including the MP joint, which is the base of the first toe B1 (see Figure 1).

In this embodiment 1, the elasticity of the first region 25, the second region 26, and the third region 27 are set as follows. The elasticity of the first region 25 is higher than that of the second region 26, and the elasticity of the third region 27 is lower than that of the second region 26. In other words, the elasticity of the first region 25 is the highest, the elasticity of the second region 26 is set next higher than that of the third region 27, and the elasticity of the third region 27 is the lowest.

The fifth region 28 and sixth region 29 are also configured to have the same elasticity as the second region 26. The second region 26, fifth region 28, and sixth region 29 extend in the foot width direction and are configured to fit the wearer's foot. Furthermore, the second region 26, fifth region 28, and sixth region 29 are also configured to have good breathability.

In the present embodiment 1, the upper midfoot region 20M and the upper rearfoot region 20R are configured with the same elasticity as the third region 27, but the elasticity of the upper midfoot region 20M and the upper rearfoot region 20R is not particularly limited.

In this embodiment 1, the upper body 20 is made of a knitted mesh fabric. The mesh fabric used has a larger mesh size in the first region 25 than in the second region 26, and a smaller mesh size in the third region 27 than in the second region 26.

By constructing the upper forefoot region 20F of the upper body 20 (upper 2) from a single continuous piece of mesh fabric, it is possible to ensure breathability in the upper forefoot region 20F. In addition, by controlling the mesh opening of the mesh fabric, it is possible to make the first region 25, which corresponds to the side of the inner foot 200 including the base of the wearer's big toe B1 (MP joint), more stretchable than other regions.

As described above, the upper forefoot region 20F of the upper body 20 (upper 2), which covers at least the wearer's forefoot LF, is formed from a single continuous piece of knitted fabric, and the first region 25, which corresponds to the medial side of the foot including the base (MP joint) of the wearer's big toe B1, is configured to be more elastic than other regions. As shown in FIG. 8, hallux valgus is a state in which the base (MP joint) of the big toe B1 protrudes and the tip is bent toward the little toe. As shown in FIG. 7, when a person with hallux valgus wears shoes 1, the base (MP joint) of the big toe B1 abuts against the first region 25 of the upper body 20 of the shoe 1. In the shoe 1 of this embodiment 1, the first region 25 corresponding to the protruding part of the base of the big toe B1 deforms outward. This relieves stress on the base of the big toe B1, and reduces discomfort caused by pain, etc., in people with hallux valgus. Furthermore, the upper forefoot region 20F is made from a single continuous piece of knit fabric, providing a comfortable fit for an athletic (e.g. running) shoe.

In this embodiment 1, the first medial side eyelet portion 20c1, which is located at the frontmost position in the foot length direction of the medial side edge of the eyelet portion 20c, is configured to be located rearward in the foot length direction from the portion of the first region 25 that corresponds to the base of the first toe B1 (MP joint).

The first medial eyelet portion 20c1, which is located at the forefront, is located behind the base of the big toe in the first region 25 in the foot length direction, so that even if the shoelace 22 is tightened, stress on the big toe is suppressed.

In this embodiment 1, as shown in Figure 2, the opening 20b further has a front end lace-through portion 20e in the center of the front end, and the front end lace-through portion 20e is positioned forward in the foot length direction from the position of the first inner foot side eyelet portion 20c1. With this configuration, the force that pulls the part of the upper 2 corresponding to the big toe B1 inward in the foot width direction when the shoelace 22 is tightened is distributed by the first inner foot side eyelet portion 20c1 and the front end lace-through portion 20e, thereby preventing stress from being applied to the big toe.

As shown in FIG. 6, the upper 2 has an inner surface 20j that faces the wearer's foot and an outer surface 20h that is exposed to the outside. A reinforcing member 20k is provided that extends to the inner and outer sides of the foot, including the center of the inner front end 20n of the forefoot region 20F of the inner surface 20j in the foot width direction.

By providing the reinforcing member 20k, damage to the upper 2 caused by the toe of the big toe thrusting upward can be suppressed.

Furthermore, the reinforcing member 20k has a protruding portion 20m that protrudes rearward in the foot length direction from the center in the foot width direction.

By having the tip of the big toe of a person with hallux valgus, which is tilted toward the center of the foot width direction, received by the protrusion 20m, damage to the upper 2 can be further suppressed.

[Modification]
A modified example of the present disclosure is shown in Fig. 9. In this modified example, a fourth region 40 having lower elasticity than the third region 27 is provided on the side of the third region 27 adjacent to the first region 25. For ease of understanding, the fourth region 40 is painted black in Fig. 7.

By providing a fourth region 40 that is less stretchy than the third region 27 on the side adjacent to the first region 25 of the third region 27, the hold on the wearer's feet can be improved.

Similarly, fourth regions 40, which are less elastic than the third region 27, are provided between the third region 27 and the fifth region 28, between the fifth region 28 and the sixth region 29, and between the third region 27, the fifth region 28, and the sixth region 29 and the toes.

[Modification 2]
In the above embodiment, the upper body 20 is made of a mesh fabric, but the present disclosure is not limited to the mesh fabric. The upper body 20 (upper 2) may be made of a fabric having an inner surface facing the wearer's foot and an outer surface exposed to the outside. At least the first region 25 and the second region 26 are provided with a plurality of recesses recessed from the outer surface 20h toward the inner surface 20j. The total area of the plurality of recesses provided in the first region 25 may be larger than the total area of the plurality of recesses provided in the second region 26.

In this way, by configuring the total area of the multiple recesses provided in the first region 25 to be larger than the total area of the multiple recesses provided in the second region 26, the first region 25, which corresponds to the side of the inner foot 200 including the base of the wearer's big toe B1 (MP joint), can be made more elastic than the other regions.

[Modification 3]
In the above embodiment, the upper forefoot region 20F is a portion located forward of the Lisfranc joint Jd, but the upper forefoot region 20F is not limited thereto and may be located forward of the foot width direction along the upper portion of the rear end of the ball of the big toe. In other words, the upper forefoot region 20F only needs to include at least a region corresponding to the medial side of the foot including the base of the wearer's big toe B1.

The above-mentioned modified examples have the same functions and effects as the above-mentioned embodiments.

Any combination of the above-described embodiments and modifications is also useful as an embodiment of the present invention. The new embodiment resulting from the combination has the combined effects of each of the combined embodiments and modifications.
