In some embodiments, if a sole is included, the footwear may be configured to make contact with the ground at the front of the outsole and the heel.

[0011] In some embodiments, the footwear may include a midsole between the bottom of the footwear body and the outsole.

[0012] In some embodiments, the footwear may be a high heel. The high heel may comprise a footwear body and a heel. The footwear body is the part that the wearer puts on their foot. In some embodiments, the footwear body may comprise a sole that covers the bottom of the wearer's foot from below and an upper that covers at least a portion of the top of the wearer's foot. In some embodiments, the heel may protrude downward from the bottom of the rear of the footwear body. In some embodiments, the high heel may be configured to make contact with the ground at the front of the sole and the heel. The heel height is not limited in any way, and the term "high heel" as used herein is not limited to so-called high heels, but includes low heels, pumps, etc.

[0013] Such a footwear body may be formed using one kind or a combination of two or more kinds among natural leather, synthetic leather, cloth made of natural fibers, cloth made of synthetic fibers, and the like. The outsole, midsole, and sole may be formed using one kind or a combination of two or more kinds among natural leather, synthetic leather, wood-based materials, resin-based materials, metal-based materials, and the like. The footwear body and the outsole, midsole, and sole may be individual members or integral members. When the footwear body and the outsole, midsole, and sole are integral members, the footwear body and the outsole, midsole, and sole may be formed of a single material or may be formed by integrally joining or molding those formed of different materials.

[0014] In some embodiments, the footwear may be socks. Socks are something that a user wears. In some embodiments, the socks have at least a part that covers the user's sole from below and a part that covers the user's instep integrally. The length of the socks may be a length down to below the user's ankle, a length up to above the user's ankle portion, a length up to the user's calf (or shin), a length up to above the user's knee, etc. when the user is wearing them. In some embodiments, the socks are not limited to so-called socks and may be stockings, tights, or the like.

[0015] The footwear may be a foot supporter. The foot supporter is something that a user wears. The supporter covers at least a part of the user's foot. The foot supporter may be formed to cover the user's sole and instep. The foot supporter may be formed to cover around the user's ankle.

[0016] When the footwear is socks or a foot supporter, the footwear may be formed from natural fibers, synthetic fibers, rubber-based materials, or the like. The footwear may be formed from a material having elasticity.

[0017] As used herein, the term “front” generally refers to the front of the user’s body while the user is wearing footwear. As used herein, the term “rear” generally refers to the rear of the user’s body while the user is wearing footwear.

[0018] As used herein, the term "width direction" generally refers to the left-right direction of the user's body while wearing the footwear. As used herein, the term "inner width direction" refers to the side of the body that is towards the center of the body in the left-right direction for the user wearing the footwear. As used herein, the term "outer width direction" refers to the side of the body that is away from the center of the body in the left-right direction for the user wearing the footwear.

[0019] In some embodiments, the footwear may include a heel support. The heel support may be configured to support the wearer's heel. The heel support may be raised upward from the bottom to support the wearer's sole. In some embodiments, the heel support may be provided in the insole of the footwear. The heel support may be attached to the insole by bonding means such as adhesive. The heel support may be formed integrally with the insole. In some embodiments, the heel support may be formed such that, when viewed from the side, the front and rear are lower than the center in the anterior-posterior direction. The heel support may include a front bulge. The front bulge is the wearer's heel Medial process of bony tori, and heel It may be formed anterior to the lateral process of the bony prominence. Such anterior prominence allows the user heel Medial process of bony tori, and heel The anterior movement of the lateral process of the bony tori is suppressed.

[0020] The heel support may have an lateral ridge. The lateral ridge is for the user heel It may be formed laterally in the width direction relative to the lateral process of the bony tuberosity. Such a lateral tuberosity can guide the supinated calcaneus to a neutral position. Alternatively, the user heel Lateral movement of the lateral process of the bony tori is suppressed.

[0021] The heel support may have an internal ridge. The internal ridge is for the user heel It may be formed medially in the width direction relative to the medial process of the bony tuberosity. Such a medial tuberosity can guide the pronated calcaneus to a neutral position. Alternatively, the user heel The medial movement of the bony tori in the width direction is suppressed. The medial tori may be formed higher than the lateral tori. This allows the user heel The medial movement of the bony tuberosity in the width direction is more effectively suppressed. Therefore, it is possible to prevent the wearer's calcaneus from tilting inward in the width direction.

[0022] In some embodiments, the outer and inner ridges may be integrally formed extending posteriorly from the anterior ridge.

[0023] In some embodiments, the footwear may further include a rear support. The rear support supports the user's heel from behind. In some embodiments, the rear support may rise upward from the bottom of the footwear body and be configured to support the entire user's heel from behind. In some embodiments, the rear support may rise upward from the bottom of the footwear body and be configured to support a portion of the lower part of the user's heel in the vertical direction from behind. In some embodiments, the rear support may be a belt-like extension from the upper of the footwear body that covers the user's instep from above. Such a rear support prevents the user's heel from moving backward. By providing a rear support in addition to a heel support, the user's calcaneus is supported more stably.

[0024] In some embodiments, the footwear may include a band provided on the footwear body. The band may be configured to plantarflex or externally rotate the base of the user's fifth metatarsal bone. The band may be configured to function to pull the corresponding portion of the user's fifth metatarsal bone downward and medially in the width direction.

[0025] The band may have a first end fixed to the footwear body. In some embodiments, the first end may be fixed to the footwear body in a portion that covers the instep of the user's foot. In some embodiments, the first end may be fixed to the footwear body in a portion other than the portion that covers the instep of the user's foot. In some embodiments, the first end may be fixed to the footwear body in a portion that is on the widthwise outer side of the instep of the user's foot.

[0026] In some embodiments, the first end may be fixed to the footwear body on the inside of the footwear body. In some embodiments, if the footwear body has a tongue on the inside of the upper, the first end may be fixed to the tongue on the inside of the footwear body. In some embodiments, the width dimension of the band of the first end may be formed to be wider as it approaches the tongue than in the middle. In some embodiments, the width dimension of the band of the first end may be constant.

[0027] The first end may be fixed to the footwear body by joining it to the footwear body by sewing, adhesive, or other means. The first end may also be integrally molded with the footwear body.

[0028] The band may have a second end configured to be secured to the footwear body. The second end may be configured to be secured to the footwear body at a corresponding location near the user's ankle. In some embodiments, the second end may be configured to lock into a position corresponding to the user's lateral malleolus. In some embodiments, the second end may be configured to extend from the widthwise inner side of the footwear body outward along the upper side of the user's foot and be secured to the footwear body. In some embodiments, the second end may be configured to wrap around a portion covering the user's ankle and be secured to the footwear body.

[0029] In some embodiments, the second end may be detachably secured to the footwear body. The second end may be detachably secured to the footwear body using a buckle, hook-and-loop fastener, or other detachable fastening component.

[0030] The band may have an intermediate section that passes from the lateral aspect of the corresponding area of ​​the user's fifth metatarsal bone to the lateral aspect of the corresponding area of ​​the first metatarsal bone. The intermediate section refers to the portion of the band between the first and second ends. In some embodiments, the band may be tightened to bring the user's fifth and first metatarsal bones closer together in the lateral direction. In some embodiments, the intermediate section of the band may be provided to pass through the corresponding area of ​​at least one of the user's navicular and cuneiform bones.

[0031] This band tightens the fifth and first metatarsals of the user's foot, bringing them closer together in the width direction. This induces plantar flexion of the base of the fifth metatarsal, maintains the medial arch, and / or guides the midfoot and beyond from abduction to adduction relative to the hindfoot. Guiding the base of the fifth metatarsal toward the sole of the foot stabilizes the lateral arch (lateral radii). Securing the belt to the ipsilateral lateral malleolus through the navicular / cuneiform bones (midfoot) stabilizes the medial arch (medial radii). Therefore, the abducted midfoot and forefoot relative to the hindfoot (calcaneus and talus) can be further guided toward adduction. Alternatively, the midfoot in the width direction is deformed to flex upward between the lateral and medial sides of the foot, thereby correcting the user's foot so that the arch is lifted upward. As a result, the user's foot is in a more ideal state during sports, walking, various tasks, exercises, rehabilitation, etc.

[0032] In some embodiments, the band may be positioned along the inner circumferential surface of the footwear body. In some embodiments, the band may be positioned along the outer circumferential surface of the footwear body.

[0033] In some embodiments, the band may be configured such that a first portion at the first end is positioned along the inner circumferential surface of the footwear body, and a second portion at the second end is positioned along the outer circumferential surface of the footwear body.

[0034] In some embodiments, the footwear body may have a slit. The slit allows a band to be inserted between a first and a second portion, thereby leading the band from the inside to the outside of the footwear body.

[0035] In some embodiments, the slit may be formed in the upper of the footwear body. In some embodiments, the slit may be formed near the boundary between the bottom and upper of the footwear body. In some embodiments, the slit may be formed in the bottom of the footwear body. In some embodiments, if an outsole is attached to the underside of the footwear body, the slit may be formed in the bottom of the footwear body. In this case, the band is led out of the slit and passes between the outsole and the bottom of the footwear body. In some embodiments, if the band passes from the slit between the outsole and the bottom of the footwear body, a groove for accommodating the band may be formed in the outsole. Also, if a midsole is provided between the body of the footwear body and the outsole, the band may pass between the outsole and the midsole or through the inside of the midsole.

[0036] As used herein, "band" generally refers to a flexible, pliable, strip-shaped or strap-shaped member. The band may be bendable in directions other than its longitudinal and widthwise directions (in the thinness direction). In some embodiments, the band may be made of various materials, including natural fibers, various synthetic fibers, and rubber-based materials. The band may be elastic or stretchable in at least part of it. The band may be elastic or stretchable in its entirety. This can, for example, improve the tightening effect on the wearer's leg. The band may not be elastic or stretchable.

[0037] In some embodiments, the footwear may include at least one of a heel support and a band. The footwear may include only a heel support from the heel support and the band. The footwear may include only a band from the heel support and the band. The footwear may include both a heel support and a band.

[0038] The footwear may be used for training, exercise, rehabilitation, and / or care. The footwear may be used for purposes other than training, exercise, rehabilitation, and / or care. The footwear may be used, for example, for purposes such as commuting, going to school, working, and daily life.

[0039] The terms "training", "exercise", "rehabilitation", and "care" will be described below using examples. The terms "training", "exercise", "rehabilitation", and "care" may be used with different meanings from each other. In some embodiments, those terms may be used with at least partially the same meaning and interchangeable meanings with each other.

[0040] The term "training" as used in this specification generally refers to physical training or physical exercise. Training may be training to improve flexibility or mobility (e.g., stretching), aerobic training (e.g., cycling, walking, jogging, swimming), anaerobic training (e.g., weight training, strength training), etc. The above classification of training is illustrative, and other classifications may be used.

[0041] The term "exercise" as used in this specification generally refers to physical movement aimed at maintaining, strengthening, recovering, improving, etc., physical ability or health. In Japanese, it is also called "運動". "Exercise" may be a sport. The sport may be various sports.

[0042] As used herein, the term “rehabilitation” generally refers to a form of musculoskeletal therapy or exercise aimed at restoring or improving a medical or therapeutic condition. Rehabilitation includes therapeutic exercise therapy, physical therapy, and movement training. Rehabilitation may, for example, be medical rehabilitation. Rehabilitation may, for example, be physical therapy. Physical therapy may, for example, be exercise therapy. Exercise therapy generally refers to therapy aimed at reducing symptoms or restoring function by moving the whole or part of the body. Exercise therapy may also be called therapeutic exercises, functional training, etc.

[0043] In some embodiments, the band may be provided with an anti-slip member on at least a portion of the side that contacts the user's foot or footwear to prevent slippage between the band and the foot. In some embodiments, the anti-slip member may be made of a rubber-based material, a silicone-based material, or the like. In some embodiments, the anti-slip member may be formed on the band in the form of points, lines, or surfaces.

[0044] Figures 1 to 9 show footwear 1A according to one embodiment. The footwear 1A shown in Figures 1 to 9 is a shoe. More specifically, footwear 1A is a sneaker. As shown in Figures 1 to 3, footwear 1A comprises a footwear body 11, an outsole 17, a band 20A, and a heel support 30A (see Figures 2 and 3).

[0045] The footwear body 11 is the part that the user puts on their foot 100. The footwear body 11 comprises a sole 12, an upper 13, a rear support 14, and a tongue 15. The sole 12 covers the sole of the user's foot from below. The sole 12 forms the bottom of the footwear body 11. The upper 13 covers the top of the user's foot 100 from above.

[0046] As shown in Figures 1 and 2, in this embodiment, the upper 13 of the footwear 1A, which is a sneaker, comprises an outside quarter 13a and an inside quarter 13b, which are divided into left and right halves in the width direction Dw. The outside quarter 13a and the inside quarter 13b are formed with a gap between them in the width direction Dw. The outside quarter 13a and the inside quarter 13b extend diagonally upward and backward from the toe portion 13t of the upper 13. The outside quarter 13a and the inside quarter 13b are connected by shoelaces (not shown).

[0047] As shown in Figures 1 to 3, the rear support 14 covers the user's heel from behind. The rear support 14 supports the user's heel from behind. The rear support 14 rises upward from the bottom 12 of the footwear body 11. As shown in Figures 1 and 2, the rear support 14 is formed continuously behind the outside quarter 13a and inside quarter 13b. The rear support 14 prevents the user's heel from moving backward.

[0048] The tongue 15 extends diagonally upward and backward from the toe portion 13t between the outside quarter 13a and the inside quarter 13b. The tongue 15 extends wider on both sides in the width direction Dw than the gap between the outside quarter 13a and the inside quarter 13b.

[0049] Furthermore, as shown in Figures 2 and 3, an insole 16 is provided inside the footwear body 11. The insole 16 is provided along the upper surface of the bottom 12. The insole 16 is in contact with the sole of the user's foot.

[0050] As shown in Figures 1 and 3, the outsole 17 is located on the underside of the footwear body 11. The outsole 17 is attached to the underside of the bottom 12 of the footwear body 11 using adhesive or the like. The outsole 17 forms the entire contact surface of the footwear 1A (sneaker, shoe).

[0051] As shown in Figures 1 to 3, the band 20A is attached to the footwear body 11. As shown in Figure 2, the band 20A is configured to pull the corresponding portion of the user's fifth metatarsal bone 125 downward and medially in the width direction Dw2. The band 20A comprises a first end 210a, a second end 210b, and an intermediate portion 210c.

[0052] The first end 210a is fixed to the footwear body 11. The first end 210a is fixed to the footwear body 11 in the area that covers the top of the user's foot 100. The first end 210a is fixed to the footwear body 11 on the top of the user's foot 100 in the area of ​​the outer width direction Dw1. As shown in Figure 4, the first end 210a is fixed to the tongue 15 on the inside of the footwear body 11. The first end 210a is joined to the outer width direction Dw1 end 15e of the tongue 15. As shown in Figures 1 and 2, the inner width direction Dw2 end 15f of the tongue 15 is fixed to the inside quarter 13b in the inner width direction Dw2. As a result, when the band 20A is pulled from the first end 210a to the second end 210b, the tension of the band 20A is transmitted via the tan 15 to the inside quarter 13b on the widthwise inner side Dw2.

[0053] As shown in Figures 2 and 4, the first end 210a is provided with a widened section 20d in which the width dimension of the band 20A gradually increases as it approaches the tongue 15 from the intermediate section 210c. The band 20A is connected to the tongue 15 via the widened section 20d. The widened section 20d is formed of, for example, flat rubber. In the widened section 20d, a viscoelastic rubber material is applied to the part that comes into contact with the instep of the foot 100 as an anti-slip measure. By increasing the area of ​​the part of the widened section 20d that comes into contact with the instep of the foot 100, the tightening force of the band 20A is efficiently transmitted to the instep of the user's foot 100.

[0054] As shown in Figures 1 to 3, the intermediate portion 210c of band 20A is formed between the first end 210a and the second end 210b of band 20A. As shown in Figure 2, the intermediate portion 210c is provided so as to pass from the lateral Dw1 in the width direction of the corresponding area of ​​the user's fifth metatarsal bone 125, through the underside of the sole of the foot, and through the medial Dw2 in the width direction of the corresponding area of ​​the first metatarsal bone 121. As shown in Figure 3, the intermediate portion 210c passes through the corresponding area near the posterior end of the fifth metatarsal bone 125 on the lateral Dw1 in the width direction. The intermediate portion 210c passes through the corresponding area of ​​at least one of the user's navicular bone 127 and cuneiform bone 129 on the medial Dw2 in the width direction.

[0055] As shown in Figures 1 to 3, the second end 210b of the band 20A is detachably fixed to the footwear body 11. The second end 210b is detachably fixed to the footwear body 11 using a buckle, hook-and-loop fastener, or other detachable fastening component. The second end 210b is configured to be fixed to the footwear body 11 at a corresponding area near the user's ankle. The second end 210b extends from the inner width direction Dw2 of the footwear body 11 to the outer width direction Dw1 along the upper side of the user's foot 100, and is configured to be fixed to the footwear body 11 near the user's ankle bone (lateral malleolus).

[0056] As shown in Figure 5, the band 20A is configured such that the first portion 20P on the first end 210a side is positioned along the inner circumferential surface of the footwear body 11, and the second portion 20Q on the second end 210b side is positioned along the outer circumferential surface of the footwear body 11. The footwear body 11 has a slit 18 that extends long in the front-to-back direction at its bottom 12. The slit 18 is formed to penetrate the bottom 12 of the footwear body 11 vertically. The band 20A is inserted between the first portion 20P and the second portion 20Q of the slit 18, thereby leading the band 20A from the inside to the outside of the footwear body 11. Preferably, the slit 18 is formed at a position approximately 0.2W from the outer width direction Dw1 of the bottom 12 in the portion where the slit 18 is provided, where W is the width direction Dw of the bottom 12. This prevents the foot 100 from being biased inward in the width direction Dw2 by the band 20A. It is preferable that the length of the slit 18 in the front-to-back direction be greater than the width dimension of the band 20A.

[0057] The band 20A, which is led out from the slit 18 to the underside of the bottom 12, passes between the outsole 17 and the bottom 12 of the footwear body 11 and is guided inward in the width direction Dw2. If the band 20A passes from the slit 18 between the outsole 17 and the bottom 12 of the footwear body 11, a groove may be formed in the outsole 17 to accommodate the band 20A.

[0058] After the user puts the footwear body 11 on their foot 100, they pull the band 20A toward the second end 210b and fix the second end 210b to the outer surface of the footwear body 11. This tightens the band 20A so that the user's fifth metatarsal bone 125 and first metatarsal bone 121 are brought closer together in the width direction Dw. This induces plantar flexion of the base of the fifth metatarsal bone, secures the medial arch, and / or guides the midfoot and forefoot relative to the hindfoot from abduction to adduction. By guiding the base of the fifth metatarsal bone toward the sole, the lateral arch (lateral radii) can be stabilized. By securing the belt 20A to the ipsilateral lateral malleolus through the navicular bone 127 / cuneiform bone portion 129 (midfoot), the medial arch (medial radii) can be stabilized. Therefore, the abducted midfoot and forefoot relative to the hindfoot (calcaneus and talus) can be further guided toward adduction. Alternatively, the middle portion 100c of the user's foot 100 is deformed to bend upward between the outer width Dw1 and the inner width Dw2 of the foot 100. This corrects the user's foot 100 so that the arch of the foot is lifted upward.

[0059] As shown in Figures 2, 3 and 6-9, the heel support 30A is provided on the insole 16 of the footwear 1A. The heel support 30A is attached to the insole 16 by bonding means such as adhesive. The heel support 30A is configured to support the user's heel. As shown in Figures 6-8, the heel support 30A integrally includes a frontal ridge 31, a lateral ridge 32 (see Figures 6 and 7), and a medial ridge 33. As shown in Figure 3, the heel support 30A rises upward from the bottom 12 that supports the sole of the user's foot. As shown in Figure 8, when viewed from the side, the heel support 30A is formed such that the central part 30c in the anterior-posterior direction Da is raised overall, while the front 30f and rear 30r are lower in comparison.

[0060] As shown in Figures 7A to 7C, the outer ridges 32 and inner ridges 33 rise upward from the upper surface of the insole 16. The height of the outer ridge 32 is formed to gradually increase toward the outer side Dw1 in the width direction. The height of the inner ridge 33 is formed to gradually increase toward the inner side Dw2 in the width direction. As shown in Figure 6, the outer ridges 32 and inner ridges 33 extend to protrude forward and backward relative to the anterior ridge 31, respectively. As a result, the heel support 30A has a rear recess 34 and a front recess 35. The rear recess 34 is formed behind the anterior ridge 31, between the outer ridges 32 and inner ridges 33 on both sides in the width direction Dw. The rear recess 34 is formed as a recess in front of the outer ridge 32 and inner ridges 33, between the outer ridges 32 and inner ridges 33 on both sides in the width direction Dw.
