Description

Technical Field

[0001] This invention relates to a shoe accessory and a shoe, and more particularly to an anti-fading sole and a running shoe. Background Technology

[0002] The support and stability of running shoes directly affect a user's running performance. However, running shoes are usually required to have a certain degree of rebound performance to help users conserve energy, which is especially important for long-distance or high-speed running.

[0003] To achieve the aforementioned performance, many running shoes on the market now feature support plates embedded in the midsole. These shoes encourage forefoot strikes, as the body's center of gravity shifts to the forefoot, generating an upward force that propels the torso forward. This results in more efficient propulsion with each stride, reducing contact time between the shoe and the ground and thus increasing cadence and pace. However, prolonged forefoot strikes place high demands on the runner's calf and ankle strength. In the later stages of marathons and other long-distance runs, the efficiency of the metatarsophalangeal and ankle joints inevitably decreases significantly, potentially leading to calf muscle cramps or strains. Due to the body's protective mechanisms, runners may unconsciously shift their foot strike point backward after prolonged running, landing on the midfoot or heel. This causes the propulsion assistance of the support plate-embedded shoes to gradually diminish, making it difficult to further increase cadence and pace, impacting long-distance running performance, and potentially causing sports injuries.

[0004] In view of this, the applicant has conducted in-depth research on the above-mentioned issues, which led to this case. Summary of the Invention

[0005] The purpose of this invention is to provide an anti-aging sole and running shoes that help improve the user's long-distance running performance and reduce sports injuries.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An anti-deterioration sole includes a midsole and a support plate embedded in the midsole. The support plate includes a heel support, an arch support, and a forefoot support that are integrally connected in sequence. An upper extension piece is integrally connected to each side of the heel support in the width direction. A lower extension piece is integrally connected to the end of the upper extension piece that is not connected to the heel support. The lower extension piece is located below the upper extension piece, and elastic filler is sandwiched between the upper extension pieces. The lower surface of the midsole is an arc surface.

[0008] As an improvement of the present invention, the upper extension piece is arranged to gradually tilt downward from back to front, and the lower extension piece is arranged to gradually tilt downward from front to back.

[0009] As an improvement of the present invention, the midsole of the shoe has a hollow area formed at a position below the heel support.

[0010] As an improvement of the present invention, the heel support includes a main body section and a rear extension section integrally connected to the rear end of the main body section. The rear extension section is arranged to gradually slope upward from front to back, and each of the upper extension pieces is connected to the front end of the main body section.

[0011] As an improvement of the present invention, the distance between the rear end of the arch support and the rear end of the midsole is 30%-35% of the length of the midsole, the distance between the front end of the arch support and the rear end of the midsole is 55%-60% of the length of the midsole, the distance between the front end of the arch support and the bottom surface of the midsole is 10-15mm, and the distance between the rear end of the arch support and the bottom surface of the midsole is 30-3.5mm.

[0012] As an improvement of the present invention, the arch support portion is in the shape of an upwardly convex arc.

[0013] As an improvement of the present invention, the shoe midsole is a foamed midsole, the support plate is a carbon plate, and the elastic filler is a foamed material.

[0014] As an improvement of the present invention, the forefoot support portion is provided with a partition groove, the partition groove being located at a position corresponding to the gap between the first and second toes of the human foot, and the partition groove communicating with the outside at the front end of the forefoot support portion.

[0015] As an improvement of the present invention, side support plates are integrally connected to both sides of the forefoot support portion in the width direction. The front end of the side support plate is connected to the forefoot support portion, and the rear end is separated from the forefoot support portion. The side support plate is located on the upper side of the forefoot support portion.

[0016] A running shoe comprising the aforementioned anti-age sole.

[0017] By adopting the above solution, the present invention has the following beneficial effects:

[0018] 1. By making the lower surface of the midsole of the shoe rounded and setting the upper and lower extension plates in the rear half of the support plate, it can still provide relatively stable support and better propulsion assistance after the runner's push-off efficiency decreases and the foot's landing point shifts from the forefoot to the midfoot or heel. This helps to improve the user's long-distance running performance and reduce sports injuries.

[0019] 2. By filling the space between the upper and lower extension plates with elastic filler, excessive deformation or breakage of the extension plates is avoided. At the same time, more stable support and more sensitive rebound capability (rebound response speed) can be provided without increasing the thickness or hardness of the support plate.

[0020] 3. Because the midsole has a hollowed-out area located below the heel support, it can not only reduce the weight of the running shoe and save running energy, but also help improve push-off efficiency, maintain arch stability, and reduce sports injuries.

[0021] 4. Utilizing the arch support to create a slope difference can provide more support for the midsection and heel, reduce ground contact time, and improve push-off efficiency; at the same time, it reduces the torsion and deformation of the arch during running, which helps to improve stability during long-distance running and reduce the risk of injury.

[0035] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0036] Example 1

[0037] like Figure 1 and Figure 2 As shown, this embodiment provides a running shoe, which includes an upper 10 and a sole 20 connected to the upper. The sole 20 is an anti-ageing sole and can be sold separately. That is, this embodiment also provides an anti-ageing sole. The specific connection structure between the upper 10 and the sole 20 is a conventional structure and is not the focus of this embodiment, so it will not be described in detail here.

[0038] The shoe sole 20 provided in this embodiment includes a midsole 21, a support plate 22 embedded in the midsole 21, and an outsole 23 covering the lower surface of the midsole 21. The midsole 21 is preferably a foamed midsole, the support plate 22 is preferably a carbon plate, and the outsole 23 is preferably a rubber outsole. The specific structure of the rubber outsole can be designed according to actual needs, and will not be described in detail here.

[0039] For ease of explanation, in this embodiment, the side of the running shoe facing its toe is the front side of each component, and the corresponding other side is the rear side. The side of the running shoe facing the ground when placed on a horizontal surface is the bottom side of each component, and the corresponding other side is the top side.

[0040] The support plate 22 includes a heel support 31, an arch support 32, and a forefoot support 33, which are integrally connected in sequence. The distance between the rear end of the arch support 32 and the rear end of the midsole 21 is 30%-35% of the length of the midsole 21. The distance between the front end of the arch support 32 and the rear end of the midsole 21 is 55%-60% of the length of the midsole 21. The distance between the front end of the arch support 32 and the bottom surface of the midsole 21 is 10-15mm. The distance between the rear end of the arch support 32 and the bottom surface of the midsole 21 is 30-3.5mm. This allows the support plate 22 to form a slope difference at the arch, providing more support for the midsection and heel, reducing ground contact time, improving push-off efficiency, and reducing torsion and deformation of the arch during running. This helps improve stability during long-distance running and reduces the risk of injury. It should be noted that the heel support 31, arch support 32, forefoot support 33, and the other pieces mentioned below are smoothly transitioned without any obvious dividing lines.

[0041] Preferably, the arch support part 32 is an upwardly convex arc shape, which provides better support.

[0042] The upper extension piece 34 is integrally connected to both sides of the heel support part 33 in the width direction. The end of the upper extension piece 34 that is not connected to the heel support part 33 (i.e. the end away from the heel support part 33) is integrally connected to the lower extension piece 35. The lower extension piece 35 is located below the upper extension piece 34. The upper extension piece 34 is arranged to gradually slope downward from back to front, and the lower extension piece 35 is arranged to gradually slope downward from front to back. Together, they form a V-shaped structure, which can form a disc spring-like effect. This ensures that even after the user runs for a long time and the foot's point of contact shifts from the forefoot to the midfoot or heel, it can still provide good assistance, avoid the gradual loss of propulsion assistance, and at the same time, avoid the loss of elasticity of the sole, thus improving the service life.

[0043] An elastic filler 36 is sandwiched between the upper extension pieces 34 and 35, providing more stable support. Furthermore, due to the different elastic moduli of the elastic filler 36 and the extension pieces, it can better respond to different forces. The specific material and elastic moduli of the elastic filler can be selected according to actual needs, such as selecting elastic rubber with a specific hardness. In this embodiment, the elastic filler 36 is a foamed material, meaning that the elastic filler 36 is made of the same material as the shoe midsole 21, and the two are integrally connected. This allows the elastic filler 36 to be filled between the upper extension pieces 34 and 35 during the foaming process to form the shoe midsole 21.

[0044] Preferably, in this embodiment, the heel support 31 includes a main body segment 41 and a rear extension segment 42 integrally connected to the rear end of the main body segment 41. The main body segment 41 is arranged horizontally or slightly inclined upward from back to front, while the rear extension segment 42 is gradually inclined upward from front to back. This allows it to cooperate with the shoe upper, enabling the shoe upper to better cover the heel and providing better support stability. Each upper extension piece 34 is connected to the front end of the main body segment 41, and both the upper extension pieces 34 and 35 are formed by cutting and bending carbon fiber blanks. Specifically, when producing the support plate 22, carbon fiber layup is first used to form a blank, and then the blank is cut and bent to form the upper extension pieces 34 and 35. Finally, the cut and bent blanks are heat-set to obtain the support plate 22.

[0045] The lower surface of the midsole 21 is rounded to facilitate better rolling during running and to work synergistically with the support plate 22 to help improve running performance in the later stages of long-distance runs. Furthermore, the midsole 21 has a hollowed-out area located below the heel support 21, exposing the lower surface of the heel support 21. This reduces the weight of the heel and helps the user maintain the point of impact on the forefoot for as long as possible during running.

[0046] Example 2

[0047] like Figure 3As shown, this embodiment provides an anti-age sole and running shoe, which differs from Embodiment 1 mainly in the structure of the forefoot support portion 21. In this embodiment, the forefoot support portion 21 has a dividing groove 37, which is located at a position corresponding to the gap between the first and second toes of the human foot. The dividing groove 37 is connected to the outside at the front end of the forefoot support portion 21, which helps to make the rebound effect respond faster and improve the assistance during the push-off phase.

[0048] Example 3

[0049] like Figure 4 As shown, this embodiment provides an anti-ageing sole and running shoe, which differs from Embodiment 1 mainly in the structure of the forefoot support portion 21. In this embodiment, side support plates 38 are integrally connected to both sides of the forefoot support portion 21 in the width direction. The front end of the side support plate 38 is connected to the forefoot support portion 21, and the rear end is separated from the forefoot support portion 21. The two side support plates 38 are located on the upper sides of the forefoot support portion 21, which improves the rebound response speed and also helps to relieve foot fatigue after long-term running.

[0050] The present invention has been described in detail above with reference to the accompanying drawings. However, the embodiments of the present invention are not limited to the above embodiments. Those skilled in the art can make various modifications to the present invention based on the prior art, and these modifications all fall within the protection scope of the present invention.
