Abstract
Description
Technical Field
[0001] This utility model relates to the field of footwear technology, and in particular to an insole with a bionic double-toe pad. Background Technology
[0002] Currently, the trail running field generally adopts the following two mainstream insole designs. One is a one-piece EVA cushioning insole, which is made of a single hardness EVA foam material from the forefoot to the heel, with a thickness of 3-5mm and a diamond or wave anti-slip texture pressed on the surface. It can provide basic cushioning and breathability and is suitable for flat and hard surfaces. The other is a single metatarsal support insole, which is made of silicone or soft TPU material, with a single raised pad at the position corresponding to the 1st to 3rd metatarsal bones in the forefoot. It can distribute the pressure on the metatarsal heads and relieve forefoot pain during long-distance walking.
[0003] However, although the above solutions can meet basic off-road requirements, they have the following common problems, especially in complex mountainous environments. Traditional designs do not specifically reinforce the push-off zones of the big toe and second toe, resulting in insufficient forefoot grip when going uphill or downhill. Utility Model Content
[0004] The purpose of this invention is to provide an insole with a biomimetic double-toe pad, which improves the insole's adaptability to complex terrain by mimicking the independent gripping mechanism of the double toes of a goat's hoof in nature, thereby improving the stability of the insole when going up or down slopes.
[0005] In a first aspect, this utility model provides an insole with a bionic double-toe pad, comprising:
[0006] The insole body includes a toe portion, a metatarsal portion, and a heel portion integrally formed in sequence. The metatarsal portion is provided with a first mounting groove and a second mounting groove, which are distributed side by side between the toe portion and the heel portion.
[0007] A first toe pad is disposed in the first mounting groove, and the first toe pad protrudes from the toe bone portion;
[0008] The second toe pad is disposed in the second mounting groove and protrudes from the toe bone portion.
[0009] This invention provides an insole with biomimetic double-toe pads. The first and second toe pads, arranged side-by-side, directly correspond to the push-off force zones of the big toe and second toe, significantly improving forefoot grip during uphill and downhill runs and addressing the shortcomings of traditional insoles in this area. The independently protruding double-toe pads form a dual-point anchoring structure, mimicking the independent gripping mechanism of a goat's hoof, providing more reliable lateral support in complex mountainous environments (such as gravel and slopes) and reducing the risk of lateral slippage. Simultaneously, the distributed support of the double-toe pads helps reduce localized high pressure on the metatarsal heads, effectively alleviating common problems in long-distance trail running such as forefoot pain, corns, and calluses, while maintaining natural toe force exertion space. Furthermore, the inclusion of first and second mounting slots not only provides precise positioning for the first and second toe pads, facilitating installation, but also accommodates thicker toe pad structures, thus significantly improving cushioning performance and grip height without affecting the shoe's internal space, enhancing traversal capabilities on complex terrain.
[0010] Furthermore, the first toe pad has a plurality of first anti-slip ridges on the side facing away from the toe bone. The first anti-slip ridges are arranged in a closed ring shape, and the plurality of first anti-slip ridges form a multi-ring nested anti-slip structure from the center of the first toe pad outward.
[0011] Using the above technical solution, the multi-ring nested first toe pad reduces pressure gradually from the center outwards, avoiding localized high pressure concentration caused by single-ring bumps, and significantly reducing the risk of forefoot pain and calluses during long-distance trail running.
[0012] Furthermore, the second toe pad has a plurality of second anti-slip ridges on the side facing away from the toe bone. The second anti-slip ridges are arranged in a closed ring shape, and the plurality of second anti-slip ridges form a multi-ring nested anti-slip structure from the center of the second toe pad outward.
[0013] Using the above technical solution, the multi-ring nested second toe pads reduce pressure gradually from the center outwards, avoiding localized high pressure concentration caused by single-ring bumps, and significantly reducing the risk of forefoot pain and calluses during long-distance trail running.
[0014] Furthermore, the first toe pad is located on the inner side of the phalanx portion, and the first toe pad is hexagonal in shape.
[0015] Furthermore, the second toe pad is located on the outer side of the toe bone portion, and the second toe pad is quadrilateral in shape.
[0016] Furthermore, the front end of the toe portion is provided with a third anti-slip ridge around the outer edge, and the third anti-slip ridge has an opening on the side facing the toe bone portion.
[0017] Using the above technical solution, the third anti-slip ridge with the opening facing the toe bone forms a "semi-encircling" structure during the push-off phase, generating an inward wrapping force on the front of the toe, effectively suppressing the forward thrust of the toe during high-speed downhill or sudden stops, and reducing the risk of toenail damage.
[0018] Furthermore, the number of the third anti-slip ridges is at least two, and the at least two third anti-slip ridges are spaced apart from the outer edge of the toe portion to the inner part of the metatarsal portion.
[0019] Using the above technical solution, at least two third anti-slip ridges are spaced apart along the outer edge of the toes to the inside of the metatarsal bone, forming a gradient anti-slip band from front to back. During the push-off phase, the toes successively contact the ridges at different heights, generating continuous "stepped" friction locking, which is suitable for off-road scenarios with rapid gear changes.
[0020] Furthermore, it also includes a support plate and a heel pad, the support plate being disposed on the heel portion, the support portion having a third mounting groove, and the heel pad being disposed within the third mounting groove.
[0021] The above technical solution utilizes a three-tiered cushioning system consisting of a support plate (rigid base), a heel pad (elastic cushioning), and toe pads to create a continuous force transmission path from the heel to the forefoot. The rigid support plate provides stable support, the elastic pad absorbs impact, and the toe pads provide propulsion; the three work together to achieve a dynamic balance between cushioning and support.
[0022] Furthermore, the support plate is provided with a fourth anti-slip ridge on the side facing the toe bone.
[0023] By adopting the above technical solution, a fourth anti-slip ridge is set to form a physical barrier, preventing the heel from sliding forward during the push-off phase and improving the stability of propulsion on slopes.
[0024] Furthermore, the support piece is provided with a fifth anti-slip ridge around the third mounting groove.
[0025] By adopting the above technical solution, an annular friction band is formed around the closed protrusion of the mounting groove, which suppresses lateral slippage of the heel and improves stability when cutting across slopes or making sharp turns.
[0026] As can be seen from the above, the insole with biomimetic double-toe pads provided by this utility model, through the side-by-side arrangement of the first and second toe pads, directly corresponds to the push-off force zone of the human big toe and second toe, significantly improving forefoot grip during uphill and downhill runs and solving the defect of insufficient grip in this area of traditional insoles. The independent protruding design of the double-toe pads forms a dual-point anchoring structure, mimicking the independent gripping mechanism of a goat's hoof, providing more reliable lateral support in complex mountainous environments (such as gravel and slopes) and reducing the risk of lateral slippage. At the same time, the distributed support of the double-toe pads helps reduce local high pressure on the metatarsal heads, effectively alleviating common problems in long-distance trail running such as forefoot pain, corns, and calluses, while maintaining natural force exertion space for the toes. In addition, by setting the first and second mounting slots, not only can the installation of the first and second toe pads be precisely positioned for convenient installation, but it can also accommodate a thicker toe pad structure, thereby significantly improving cushioning performance and grip height without affecting the internal space of the shoe, and enhancing the passability of complex terrain.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0031] The following disclosure provides many different embodiments or examples for implementing various structures of the present invention. To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or reference letters may be repeated in different examples; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.
[0032] The present invention discloses an insole with a biomimetic double-toe pad, which is mainly used in off-road scenarios. By imitating the independent gripping mechanism of the double toes of a goat's hoof in nature, the insole improves its terrain adaptability in complex terrain, thereby improving stability when going uphill or downhill.
[0033] Reference Appendix Figure 1 In one embodiment, the insole with bionic double-toe pads includes an insole body 100, a first toe pad 200, and a second toe pad 300. The insole body 100 includes a toe portion 110, a metatarsal portion 120, and a heel portion 130 integrally formed in sequence. The metatarsal portion 120 is provided with a first mounting groove 121 and a second mounting groove 122, which are arranged side by side between the toe portion 110 and the heel portion 130. The first toe pad 200 is disposed in the first mounting groove 121 and protrudes from the metatarsal portion 120. The second toe pad 300 is disposed in the second mounting groove 122 and protrudes from the metatarsal portion 120.
[0034] Specifically, the first toe pad 200 is used to provide support for the first metatarsal bone, and the second toe pad 300 is used to provide support for the fifth metatarsal bone.
[0035] As can be seen from the above, the insole with biomimetic double-toe pads provided by this utility model, through the side-by-side arrangement of the first toe pad 200 and the second toe pad 300, directly corresponds to the push-off force zone of the human big toe and second toe, significantly improving forefoot grip during uphill and downhill runs and solving the defect of insufficient grip in this area of traditional insoles. The independently protruding design of the double-toe pads forms a dual-point anchoring structure, mimicking the independent gripping mechanism of a goat's hoof, providing more reliable lateral support in complex mountain environments (such as gravel and slopes) and reducing the risk of lateral slippage. At the same time, the distributed support of the double-toe pads helps reduce local high pressure on the metatarsal heads, effectively alleviating common problems such as forefoot pain, corns, and calluses in long-distance trail running, while maintaining natural force exertion space for the toes. Furthermore, by setting the first mounting groove 121 and the second mounting groove 122, not only can the installation of the first toe pad 200 and the second toe pad 300 be precisely positioned for convenient installation, but it can also accommodate a toe pad structure with greater thickness. Thus, without affecting the space inside the shoe, the cushioning performance and grip height are significantly improved, and the passability of complex terrain is enhanced.
[0036] In one embodiment, the first toe pad 200 is provided with a plurality of first anti-slip ridges 210 on the side facing away from the toe bone portion 120. The first anti-slip ridges 210 are arranged in a closed ring shape, and the plurality of first anti-slip ridges 210 form a multi-ring nested anti-slip structure from the center of the first toe pad 200 outward.
[0037] Using the above technical solution, the multi-ring nested first toe pad 200 reduces pressure gradually from the center outwards, avoiding local high pressure concentration caused by single-ring bumps, and significantly reducing the risk of forefoot pain and calluses during long-distance trail running.
[0038] In one embodiment, the second toe pad 300 is provided with a plurality of second anti-slip ridges 310 on the side opposite to the metatarsal portion 120. The second anti-slip ridges 310 are arranged in a closed ring shape, and the plurality of second anti-slip ridges 310 form a multi-ring nested anti-slip structure from the center of the first toe pad 200 outward.
[0039] Using the above technical solution, the multi-ring nested second toe pad 300 reduces pressure gradually from the center outwards, avoiding local high pressure concentration caused by single-ring bumps, and significantly reducing the risk of forefoot pain and calluses during long-distance trail running.
[0040] In one embodiment, a first toe pad 200 is disposed on the inner side of the phalanx portion 120, and the first toe pad 200 is hexagonal in shape.

[0043] Using the above technical solution, the third anti-slip ridge 111 with the opening 112 facing the toe bone 120 forms a "semi-encircling" structure during the push-off phase, generating an inward wrapping force on the front of the toe, effectively suppressing the forward rushing of the toe during high-speed downhill or sudden stop, and reducing the risk of toenail damage.
[0044] In one embodiment, the number of third anti-slip ridges 111 is at least two, and the at least two third anti-slip ridges 111 are spaced apart from the outer edge of the toe portion 110 to the inner part of the metatarsal portion 120.
[0045] Using the above technical solution, at least two third anti-slip ridges 111 are spaced apart along the outer edge of the toe portion 110 to the inside of the metatarsal portion 120, forming a gradient anti-slip band from front to back. During the push-off phase, the toes successively contact the ridges of different heights, generating continuous "stepped" friction locking, which is suitable for off-road scenarios with rapid gear changes.
[0046] In one embodiment, the system also includes a support plate 400 and a heel pad 500. The support plate 400 is disposed on the heel portion 130 and has a third mounting groove 410. The heel pad 500 is disposed within the third mounting groove 410.
[0047] By employing the above technical solution, a continuous force transmission path is formed from the heel to the forefoot through a three-level cushioning system consisting of a support plate 400 (rigid base), a heel pad 500 (elastic cushioning), and toe pads. The rigid support plate 400 provides stable support, the elastic pad absorbs impact, and the toe pads are responsible for propulsion; the three work together to achieve a dynamic balance between cushioning and support.
[0048] In one embodiment, the support piece 400 is further provided with a fourth anti-slip protrusion 420 on the side facing the metatarsal portion 120.
[0049] By adopting the above technical solution, a fourth anti-slip protrusion 420 is set to form a physical barrier, preventing the heel from sliding forward during the push-off phase and improving the stability of propulsion on slopes.
[0050] In one embodiment, the support piece 400 is further provided with a fifth anti-slip protrusion 430 around the third mounting groove 410.
[0051] By adopting the above technical solution, an annular friction band is formed around the closed protrusion of the mounting groove, which suppresses lateral slippage of the heel and improves stability when cutting across slopes or making sharp turns.
