4. The foot cushioning device as claimed in claim 3, wherein the adjusting piece located in the first support region contacts the first position near the head of the first metatarsal bone to provide the head of the first metatarsal bone to move in a direction away from the ground, and the thickness distribution of the adjusting piece gradually increases from the first position toward the head of the first metatarsal bone to conform to the angle between the first metatarsal bone and the horizontal to form a slope.
5. The foot cushioning device as described in claim 1, wherein the cushioning body has a rear foot portion, the material of the rear foot portion having a first compressive strength, and a compressive strength reduction structure is provided on an inner side of the rear foot portion, wherein the compressive strength reduction structure made of the same material has a second compressive strength less than the first compressive strength, the second compressive strength preventing the user from experiencing a foreign body sensation at the location of the compressive strength reduction structure when standing statically, but allowing for more flexible deformation when the user walks, thus finely adjusting and correcting an excessively hyper-twisted foot twisting pattern to an appropriate foot twisting pattern.
6. The foot cushioning device as claimed in claim 5, wherein the structure for reducing compressive deformation includes a groove structure and at least one sidewall and a bottom around the groove structure, the sidewall and the bottom being made of the same material as the hindfoot portion, the long side of the groove structure being substantially parallel to the direction of extension of the transverse arch of the user's foot, and the short side of the groove structure being substantially parallel to the direction of extension of the longitudinal arch of the user's foot, and the depth of the groove structure gradually decreasing along the direction of extension of its long side, such that the depth of the groove structure in the edge region of the cushioning body is greater than the depth of the groove structure in the central region of the cushioning body.
7. A foot cushioning device, characterized in that it is disposed between a user's foot and the ground, the device comprising at least a cushioning body located between the user's foot and the ground, the cushioning body having a forefoot portion, the forefoot portion including a first support region and a second support region, wherein the position of the first support region corresponds to a first metatarsal bone of the user's foot, the position of the second support region corresponds to the remaining region of the forefoot portion, the first support region having a support structure for applying force to the foot at a first position near a head of the first metatarsal bone, causing the head of the first metatarsal bone to move away from the ground, the support structure having a hollow structure, the position of the hollow structure corresponding to the first position.
8. The foot cushioning device as described in claim 7, wherein the cushioning body has a rear foot portion, the material of the rear foot portion having a first compressive strength, and a compressive strength reduction structure is provided on an inner side of the rear foot portion, wherein the compressive strength reduction structure made of the same material has a second compressive strength that is less than the first compressive strength, the second compressive strength ensuring that the user does not experience a foreign body sensation at the location of the compressive strength reduction structure when standing statically, but when the user walks, it can be more easily deformed to finely adjust and correct the hyper-twist foot twisting pattern to an appropriate foot twisting pattern.
9. The foot cushioning device as claimed in claim 8, wherein the structure for reducing compressive deformation includes a groove structure and at least one sidewall and a bottom around the groove structure, the sidewall and the bottom being made of the same material as the hindfoot portion, the long side of the groove structure being substantially parallel to the transverse arch of the user's foot, and the short side of the groove structure being substantially parallel to the longitudinal arch of the user's foot, the depth of the groove structure gradually decreasing along the direction of its long side, such that the depth of the groove structure in the edge region of the cushioning body is greater than the depth of the groove structure in the central region of the cushioning body.
10. A foot cushioning device, characterized in that it is disposed between a user's foot and the ground, the device comprising at least a cushioning body located between the user's foot and the ground, the cushioning body having a forefoot portion, the forefoot portion including a first support region and a second support region, wherein the position of the first support region corresponds to a first metatarsal bone of the user's foot, the position of the second support region corresponds to the remaining region of the forefoot portion, and a recess in the first support region is close to a first position of a head of the first metatarsal bone, for providing the head of the first metatarsal bone to move toward the ground.
11. The foot cushioning device as claimed in claim 10, wherein the cushioning body is an insole, the insole is integrally molded, wherein the first support area and the second support area of the forefoot portion are made of the same process and the same material as other parts of the insole, and the minimum total thickness of the first support area is smaller than the minimum total thickness of the second support area.
12. The foot cushioning device as claimed in claim 10, wherein the cushioning body is an insole, the insole comprising a plurality of adjustment tabs located in the first support region and the second support region, such that the minimum total thickness in the first support region is smaller than the minimum total thickness in the second support region, and the total thickness distribution of the second support region gradually decreases from the outer edge of the sole to the inner edge of the sole, thereby assisting in lifting the outer edge of the foot supported by the second support region and slightly rotating it towards the first support region to form an elastic arch shape, thereby finely adjusting and correcting the torsional state of the foot to an appropriate torsional state.
13. The foot cushioning device as claimed in claim 12, wherein the adjustment piece located in the first support region has the recess at the first position adjacent to the head of the first metatarsal bone, for providing the head of the first metatarsal bone to move toward the ground, the depth distribution of the recess gradually decreasing from the first position toward the head of the first metatarsal bone, for providing the head of the first metatarsal bone to move toward the ground.
14. The foot cushioning device as claimed in claim 10, wherein the cushioning body includes a rear foot portion and a gait guidance structure, wherein the material of the rear foot portion has a first compressive strength, the gait guidance structure is disposed on the rear foot portion, located between the cushioning body and the ground, the hardness of the gait guidance structure material is in the range of 40 to 70 on the Shore C hardness index, and the second compressive strength of the gait guidance structure material is greater than the first compressive strength, and the gait guidance structure includes a first surface, a second surface, and a groove structure, wherein the angle between a first side of the groove structure and the direction of extension of the transverse arch of the user's foot is less than 30°, and the angle between a second side of the groove structure and the direction of extension of the longitudinal arch of the user's foot is... The angle is less than 30°. The depth of the groove structure gradually decreases with the extension direction of the first side. The depth of the groove structure located in the edge area of the buffer body is greater than the depth of the groove structure located in the central area of the buffer body. The thickness of the gait guidance structure gradually decreases with the extension direction of the first side to form a slope. The slope makes a first thickness between the first surface and the second surface on the inner side of the hind foot part greater than a second thickness between the first surface and the second surface on the outer side of the hind foot part. When the user walks, the slope is used to guide the user to be in a relatively twisted state after the user's hind foot fully touches the ground. Then, due to the more easily deformable groove structure, the hind foot is guided, thereby achieving the fine adjustment and correction of the foot twist pattern to an appropriate foot twist pattern.
15. The foot cushioning device as claimed in claim 14, wherein the cushioning body is an insole placed in the shoe, and the gait guidance structure is located between the shoe and the insole.
16. The foot cushioning device as claimed in claim 15, wherein the insole is a foam material comprising one of ethylene-vinyl acetate copolymer, polyurethane, and slow-rebound sponge.
