Description

Technical Field

[0001] This utility model relates to the field of shoe technology, specifically to a shoe sole and a shoe. Background Technology

[0002] Sports involve frequent, rapid, and varied movements, requiring shoe sole tread patterns to coordinate with these movements to enhance athletic performance. During the contact between the shoe sole and the ground, different areas of the sole come into contact with the ground depending on the movement. To improve performance, different areas of the sole need different tread patterns designed for different movements to enhance grip, braking, and propulsion. Current shoe sole tread patterns are sometimes limited to a single design, failing to meet the requirements of different movements in different areas of the sole; others, while featuring different tread patterns, fail to adequately consider the specific needs of different areas of the sole for various movements, severely impacting athletic performance. Utility Model Content

[0003] The purpose of this invention is to overcome the above-mentioned defects or problems in the prior art and to provide a sole and shoe that improves grip, braking and propulsion.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A shoe sole is characterized by comprising a plurality of continuously bent ridges protruding from the bottom surface of the sole, wherein the ridges form openings at the bends; the ridges include a first ridge, the first ridge extending in an inward and outward direction and the opening direction being a forward and backward direction; the bottom surface of the sole includes a first region, the first region being located at a position corresponding to the front side of the metatarsophalangeal joint; the first ridge is disposed in the first region along the forward and backward direction, and the height of the first ridge protruding from the bottom surface of the sole gradually decreases along the forward and backward direction.

[0006] Furthermore, the first region sequentially includes a second region and a third region along the inner and outer directions, and the first protrusion includes a second protrusion and a third protrusion; the second protrusion is disposed in the second region, the third protrusion is disposed in the third region, and the distance between adjacent second protrusions is smaller than the distance between adjacent third protrusions.

[0007] Furthermore, the sole surface includes a fourth region located at the corresponding position of the first and second proximal phalanges, and the ridge includes a fourth ridge; the fourth region includes a circular ring protruding from the sole surface and the fourth ridge disposed within the circular ring, and the spacing between adjacent fourth ridges is greater than the width of the fourth ridge.

[0008] Furthermore, the inner side of the forefoot portion of the sole includes a fifth region; the ridge includes a fifth ridge, the fifth ridge extending in the inward and outward direction and opening in the forward and backward direction, the fifth ridge being disposed in the fifth region along the forward and backward direction.

[0009] Furthermore, the sole surface includes a sixth region, which is at least partially located at the corresponding positions of the fourth and fifth metatarsal bones; the ridge includes a sixth ridge, which extends in a front-to-back direction and opens in an inward-outward direction; the sixth ridge is disposed in the sixth region along the inward-outward direction, and the spacing between adjacent sixth ridges is equal to the width of the sixth ridge.

[0010] Furthermore, the inner side of the heel portion of the sole includes a seventh region, and the convex strip includes a seventh convex strip. The extension direction of the seventh convex strip is in the inward and outward direction, and the opening direction is in the forward and backward direction. The seventh convex strip is disposed in the seventh region along the forward and backward direction, and the distance between adjacent seventh convex strips is less than the width of the seventh convex strip.

[0011] Furthermore, the outer side of the heel portion of the sole includes an eighth region, and the ridge includes an eighth ridge. The extension direction of the eighth ridge is the front-to-back direction, and the opening direction is the inward-outward direction. The eighth ridge is disposed in the eighth region along the inward-outward direction, and the spacing between adjacent eighth ridges is greater than the width of the eighth ridge.

[0012] Furthermore, the convex strip includes several elongated protrusions, with adjacent protrusions extending in different directions to form continuous bends and openings; the width of the protrusions of the first convex strip gradually decreases along the front-back direction.

[0013] Furthermore, the length of the protrusion of the first protrusion and the opening angle formed by adjacent protrusions gradually decrease in the front-rear direction.

[0014] A shoe characterized by comprising an upper and a sole as described in any of the preceding claims.

[0015] As can be seen from the above description of the present invention, compared with the prior art, the present invention has the following beneficial effects:

[0016] The first technical solution involves a sole comprising several continuously bent ridges protruding from the bottom surface of the sole, with openings formed at the bends. Compared to straight ridges, continuously bent ridges improve grip in all directions, preventing insufficient grip in any particular direction. The bottom surface of the sole includes a first region located at the area corresponding to the front of the metatarsophalangeal joint. During forward sprinting and jumping, the metatarsophalangeal joint bends to generate force, and the area in front of the metatarsophalangeal joint contacts the ground. The ridges include a first ridge, which extends inward and outward and opens inward and backward. During forward sprinting and jumping, the relative motion of the first region with the ground is in the same direction as the opening of the first ridge, causing the first ridge to wedge into the ground. The deformation of the first ridge better conforms to the ground, improving sole grip and better transferring force to the ground and receiving ground reaction forces.

[0017] The first convex strip is positioned along the front-to-back direction in the first area, and the height of the first convex strip protruding from the bottom surface of the sole gradually decreases along the front-to-back direction. The height of the first convex strip located at the front of the first area is greater than that of the first convex strip located at the rear. During the forward sprint and take-off movements, in the early stage of the movement, the rear of the first area contacts the ground. The smaller height of the first convex strip at this position results in less deformation, allowing the force used for the forward sprint and take-off to be quickly transferred to the ground, increasing the starting speed. In the later stage of the movement, the front of the first area contacts the ground. The larger height of the first convex strip at this position results in greater deformation, better contact between the first convex strip and the ground, and more of the first convex strip wedged into the ground, improving grip and stable support. This increases friction and the ground reaction force received, thereby improving the performance of the forward sprint and take-off movements.

[0018] The second technical solution involves a first region sequentially comprising a second region and a third region along an inward-outward direction. The second region is located on the inner side, and the third region is located on the outer side. During a forward sprint, the primary force exertion point of the foot is located in the area between the big toe and the second finger, corresponding to the inner side of the sole. The first convex strip includes a second convex strip and a third convex strip. The second convex strip is located in the second region, and the third convex strip is located in the third region. The distance between adjacent second convex strips is smaller than the distance between adjacent third convex strips, meaning that the number of convex strips in the sole area corresponding to the big toe and the second finger is higher, further improving grip and enabling better, faster acceleration during a forward sprint.

[0019] The third technical solution involves a fourth region on the sole surface, located at the position corresponding to the first and second proximal phalanges. During turning, this region primarily involves the area corresponding to the first and second proximal phalanges in contact with the ground. The fourth region includes a circular ring protruding from the sole surface and a fourth raised strip within the circular ring. The distance between adjacent fourth raised strips is greater than the width of the fourth raised strip, and the area of ​​the fourth raised strip within the circular ring is smaller than the distance between the fourth raised strips. This reduces the contact area between the fourth region and the ground, decreasing friction at this location during rotational movements and allowing for more flexible turning of the forefoot.

[0020] The fourth technical solution involves a fifth region on the inner forefoot side of the sole, with a fifth raised rib. The fifth raised rib extends in an inward-outward direction and opens in a forward-backward direction. The fifth raised rib is positioned within the fifth region along the forward-backward direction, meaning the distance between adjacent fifth raised ribs extends in an inward-outward direction. The inner forefoot side is close to the metatarsophalangeal joint, which frequently flexes during movement. The fifth raised rib improves the grip on the inner side of the sole, while the distance between adjacent fifth raised ribs provides space for forefoot flexion, enhancing the flexibility of the metatarsophalangeal joint.

[0021] The fifth technical solution involves a sixth region on the sole, at least partially located at the positions corresponding to the fourth and fifth metatarsal bones. During lateral movement and sudden lateral stops, primarily the outer portion of the sole contacts the ground, with the sole moving in an inward-outward direction relative to the ground. The fourth and fifth metatarsal bones correspond to the outer portions of the sole. The sixth ridge extends in a forward-backward direction and opens in an inward-outward direction, positioned within the sixth region along this direction. The inward-outward openings wedge into the ground during lateral movement, enhancing grip. The width of the sixth ridge in the sixth region is the same as the spacing between adjacent ridges, ensuring balanced grip in the sixth region and improving braking and propulsion in various movement states, including lateral movement and sudden lateral stops.

[0022] The sixth technical solution involves a seventh region on the inner side of the heel area of ​​the sole, with a seventh ridge extending inwards and outwards, and opening in the forward-backward direction. This seventh ridge is positioned within the seventh region along the forward-backward direction. During rearward movement, as the body moves towards the back, the rear side of the sole becomes the primary contact area. The forward-backward opening wedges into the ground, improving grip and thus enhancing braking performance during rearward movements. The spacing between adjacent seventh ridges is less than the width of the seventh ridge, increasing the contact area between the seventh region and the ground, further enhancing grip.

[0023] The seventh technical solution involves an eighth region on the outer heel area of ​​the sole, containing an eighth raised strip. The eighth raised strip extends in a front-to-back direction and opens in an inward-outward direction, positioned within the eighth region along these directions. The direction of the eighth raised strip differs from that of the seventh raised strip, enhancing grip in all directions during rearward movement. The spacing between adjacent eighth raised strips is greater than the width of the eighth raised strip, resulting in fewer raised strips per unit area. This allows for easier deformation under stress and energy absorption during deformation, reducing injury to the knees and feet.

[0024] The eighth technical solution includes a raised strip comprising several elongated protrusions. The raised strip is composed of these protrusions, with adjacent protrusions extending in different directions to form continuous bends and openings. The width of the protrusions in the first raised strip of the first region gradually decreases along the front-to-back direction. During forward sprinting and take-off movements, the front of the first region contacts the ground in the later stages of the movement. The protrusions of the first raised strip at this position are wider, increasing the contact area between the sole of the first region and the ground. More of the first raised strips wedge into the sole surface, providing grip and stability. This increases friction while also increasing the ground reaction force received, thereby improving the performance of forward sprinting and take-off movements.

[0025] The ninth technical solution involves a first convex strip whose length and the opening angle formed by adjacent protrusions gradually decrease along the front-back direction. During the forward sprint and take-off movements, in the early stage of the movement, the rear of the first region contacts the ground. In this region, the length of the first convex strip is small, and the opening angle formed by adjacent protrusions is small, resulting in more continuous bending and further improving the grip of the first convex strip in all directions during the early stage of the movement, allowing it to quickly and stably enter the starting state. In the later stage of the movement, the front of the first region contacts the ground. When the opening direction of the first convex strip is front-back, the length of the protrusion and the opening angle formed by adjacent protrusions increase, allowing the ground reaction force received by the first convex strip to better propel the forward sprint and take-off.

[0026] The tenth technical solution is a shoe comprising an upper and any of the aforementioned soles, the shoe being able to provide adaptive grip, propulsion, and braking for different movement states during exercise. Attached Figure Description

[0036] See Figure 1 , Figure 2 , Figure 1 A schematic diagram of the sole surface is shown. Figure 2 A schematic diagram of the shoe sole and foot is shown.

[0037] A shoe includes an upper and a sole. The sole of this application features a continuous, bent ridge 20 protruding from the bottom surface, with openings formed at the bends. Compared to straight ridges 20, the continuous bent ridges 20 improve grip in all directions, preventing insufficient grip in any particular direction. Furthermore, the continuous ridges 20 distribute the force generated during relative movement between the sole and the ground across more ridges, preventing force concentration in one area and avoiding severe deformation that could affect grip. When the openings at the bends are in the same direction as the movement, the first ridge 21 wedges into the ground, allowing for better conformity between the first ridge 21 and the ground, improving sole grip and better transferring force to and receiving ground reaction forces.

[0038] Based on the different contact points between the sole and the ground under different sports conditions, the sole is divided into the first area 11, the fourth area 14, the fifth area 15, the sixth area 16, the seventh area 17, and the eighth area 18.

[0039] The first region 11 is located at the area corresponding to the front of the metatarsophalangeal joint. The raised strip 20 includes a first raised strip 21, which extends in an inward / outward direction and opens in a forward / backward direction. The first raised strip 21 is positioned in the first region 11 along the forward / backward direction, and the height of the first raised strip 21 protruding from the bottom surface of the sole gradually decreases along the forward / backward direction. In this application, the forward / backward direction is from the forefoot to the heel, and the inward / outward direction is from the thumb to the little finger. During forward sprinting and jumping, the area where the bottom surface of the sole contacts the ground is mainly located at the area corresponding to the metatarsophalangeal joint.

[0040] During the forward sprint and take-off, the relative movement direction of the first area 11 with the ground is forward-backward, the same as the opening direction of the first protrusion 21. This allows the first protrusion 21 to wedge into the ground, and its deformation to better conform to the ground, improving the sole's grip and better transmitting force to the ground and receiving the ground's reaction force. The first protrusion 21 is positioned along the forward-backward direction in the first area 11, and the height of the first protrusion 21 protruding from the bottom surface of the sole gradually decreases along the forward-backward direction. The height of the first protrusion 21 located in front of the first area 11 is greater than that of the first protrusion 21 located behind. During the forward sprint and take-off, in the early stage of the movement, the rear of the first area 11 contacts the ground. The first protrusion 21 at this position has a smaller height and generates less deformation, allowing the force used for the forward sprint and take-off to be quickly transmitted to the ground, increasing the starting speed. In the later stage of the movement, the front of the first area 11 contacts the ground. The first protrusion 21 located at this position has a large height and generates a large deformation. The first protrusion 21 fits the ground better, and more of the first protrusion 21 wedges into the ground, improving grip and stable support. While increasing friction, it also increases the ground reaction force received, improving the performance of forward sprinting and take-off.

[0041] The convex strip 20 includes an elongated protrusion 30, with adjacent protrusions 30 extending in different directions to form continuous bends and openings. In this embodiment, the length, width, and opening angle formed by adjacent protrusions 30 of the first convex strip 21 gradually decrease along the front-rear direction. During the forward sprint and take-off movements, the front of the first region 11 contacts the ground in the later stage of the movement. The protrusions 30 of the first convex strip 21 located at this position are wider, increasing the contact area between the sole of the first region 11 and the ground, and more first convex strips 21 wedge into the bottom surface, providing grip and stability. This increases friction and the ground reaction force received, improving the performance of forward sprints and take-off movements. During the forward sprint and take-off movements, the rear of the first region 11 contacts the ground in the early stage of the movement. The length of the first convex strip 21 in this region is small, and the opening angle formed by adjacent protrusions 30 is small, resulting in more continuous bends. This further improves the grip of the first convex strip 21 in all directions in the early stage of the movement, allowing it to quickly and stably enter the starting state. In the later stages of the movement, the front of the first region 11 contacts the ground. When the opening direction of the first protrusion 21 is in the front-back direction, the length of the protrusion 30 of the first protrusion 21 and the opening angle formed by the adjacent protrusions 30 increase, so that the ground reaction force received by the first protrusion 21 can better propel the forward sprint and push off the ground to jump.

[0042] The first region 11 includes a second region 12 and a third region 13 sequentially along the inward and outward directions. The first protrusion 21 includes a second protrusion 22 and a third protrusion 23. The second protrusion 22 is located in the second region 12, and the third protrusion 23 is located in the third region 13. The spacing between adjacent second protrusions 22 is smaller than the spacing between adjacent third protrusions 23. The number of protrusions 20 on the inner side of the sole surface corresponding to the thumb and second toe is greater than that on the outer side. During forward sprinting, more protrusions 20 wedge into the ground, providing better energy transfer and increasing starting speed.

[0043] The fourth region 14 is located on the sole surface corresponding to the first and second proximal phalanges, and the ridge 20 includes a fourth ridge 24. The fourth region 14 includes a circular ring 34 protruding from the sole surface and a fourth ridge 24 disposed within the circular ring 34. In this embodiment, the fourth ridge 24 extends in a front-to-back direction and opens in an inward-outward direction, and is disposed in the fourth region 14 along the inward-outward direction. The distance between adjacent fourth ridges 24 is greater than the width of the fourth ridge 24. The fourth region 14 is the area where the sole surface contacts the ground when the human body turns. To maintain turning flexibility, the friction between this area and the ground cannot be too high. The distance between adjacent fourth ridges 24 in the fourth region 14 is greater than the width of the fourth ridge 24, reducing the contact area with the ground, reducing friction, and improving turning flexibility.

[0044] The fifth region 15 is located on the inner side of the forefoot area of ​​the sole. The raised strip 20 includes a fifth raised strip 25, which extends inwards and outwards and opens inwards and backwards. The fifth raised strip 25 is positioned along the forward-backward direction within the fifth region 15. The spacing between adjacent fifth raised strips 25 is greater than the width of each strip. During forward sprints and jumps, the metatarsophalangeal joint frequently flexes. The fifth raised strip 25 in the fifth region 15 reduces the flexing intensity in this area, preventing the sole from being too stiff and restricting movement. The fifth raised strip 25 also enhances the grip on the inner side of the sole.

[0045] The sixth region 16 is located on the sole surface of the shoe, corresponding to the fifth, fourth, fifth, fourth, third, and second metatarsal bones. The ridge 20 includes a sixth ridge 26, which extends in a front-to-back direction and opens in an inward-outward direction. The sixth ridge 26 is positioned in the sixth region 16 along the inward-outward direction, and the distance between adjacent ridges 26 is equal to the width of the sixth ridge 26. During lateral stops and rapid changes of direction, the parts in contact with the ground are mainly the areas corresponding to the fifth, fourth, fifth, fourth, third, and second metatarsal bones. Furthermore, during lateral stops, the sole moves in an inward-outward direction relative to the ground. Since the opening of the sixth ridge 26 is in an inward-outward direction, it can better wedge into the ground during deformation, increasing grip and achieving rapid and stable braking. The spacing between adjacent sixth protrusions 26 is the same as the width of the sixth protrusion 26. This ratio improves the overall stability of the sole and enhances the lateral emergency braking performance, enabling accurate stopping during rapid changes of direction and improving the accuracy and safety of movement.

[0046] The seventh region 17 is located on the inner side of the heel area of ​​the sole. The raised strip 20 includes a seventh raised strip 27, which extends inwards and outwards and opens inwards and backwards. The seventh raised strip 27 is positioned along the forward-backward direction within the seventh region 17. The spacing between adjacent seventh raised strips 27 is less than the width of each seventh raised strip 27. This increases the number of raised strips 20 within a single surface area, increasing the contact area with the ground and improving the friction for backward braking.

[0047] The eighth region 18 is located on the outer side of the heel area of ​​the sole. The raised strip 20 includes an eighth raised strip 28, which extends in a front-to-back direction and opens in an inward-outward direction. The eighth raised strip 28 is positioned in the eighth region 18 along the inward-outward direction, and the distance between adjacent eighth raised strips 28 is greater than the width of the eighth raised strip 28. This region has a small number of eighth raised strips 28, making them more susceptible to deformation under the high pressure of contact with the ground. This deformation absorbs some energy, reducing the force on the foot during exercise and minimizing foot injury.

[0048] This application provides a shoe sole and shoe, in which different continuously bent ridges 20 are provided in different areas of the sole surface according to the different contact parts of the sole surface with the ground under different sports states. By setting the extension direction, opening direction, spacing between adjacent ridges 20, layout direction of ridges 20, length and width of protrusions 30, and opening angle formed by adjacent protrusions 30, the needs of different parts of the sole surface under different sports states are met, thereby improving grip, stability, braking and propulsion during sports.

[0049] The foregoing description of the specifications and embodiments is intended to explain the scope of protection of this utility model, but does not constitute a limitation on the scope of protection of this utility model. Modifications, equivalent substitutions, or other improvements to the embodiments of this utility model or a portion thereof that can be obtained by those skilled in the art through logical analysis, reasoning, or limited experimentation, based on the teachings of this utility model or the foregoing embodiments, should all be included within the scope of protection of this utility model.
