[0013] The utility model also provides a sole, aiming to improve the problem that the sole structure of existing shoes has little or no benefit in running sports.

[0014] To achieve the above purpose, the utility model adopts the following technical solution: a sole, comprising:

[0015] A carbon plate, which is the above-mentioned carbon plate for shoes; and

[0016] The shoe midsole comprises an upper midsole and a lower midsole, and a contour groove for placing the carbon plate is arranged on the joint surface of the upper midsole or the lower midsole.

The medial support area can provide good support performance to ensure the structural stability of the sole. The lateral support area has a shock-absorbing effect, which allows the runner to transfer the force from the outside of the forefoot to the inside, forming a running posture that conforms to human functional science and avoids sprains. The design of the lateral support area can effectively cushion the pedaling action. The middle ejection area in the middle position can provide elasticity, help runners exert force, provide benefits for running, and has good practicality.

[0023] 2. By independently designing the medial support area, the lateral support area and the middle ejection area, the corresponding functions can be designed respectively, and the influence between them is small or no influence, which can improve their respective performance and improve the performance of the carbon plate for shoes.

[0024] 3. In order to adapt to the action of professional runners when running, the outer side of the forefoot touches the ground first, then the inner side of the forefoot and the middle waist and heel. The forefoot of the sole is designed to be raised to match the structural design of the forefoot of the shoe carbon plate, so as to achieve the required running action, improve the efficiency of exercise, and protect the knee joints.

[0025] 4. The design of the first window and the second window disperses the force to both sides when running, providing a high shock-absorbing effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] Embodiment 1

[0044] Please refer to Figure 1 and Figure 2 As shown, the present embodiment provides a carbon plate for shoes, including a rear sole portion 10 and a forefoot portion 20, wherein the forefoot portion 20 is provided with an inner support area 201, an outer support area 202 and a middle ejection area 203 located between the inner support area 201 and the outer support area 202, and a fracture 204 is formed between the inner support area 201 and the outer support area 202; a curved portion 205 for the toe area to be tilted is provided on the forefoot portion 20, and the curvature of the curved portion 205 of the middle ejection area 203 is greater than the curvature of the curved portion 205 of the inner support area 201 or the side support area.

[0045] Specifically, the carbon plate for shoes is independently designed on the forefoot part 20, that is, a "U"-shaped hole with an opening facing the heel direction is designed on the forefoot part 20, and a break 204 is designed between the outer area and the toe area, so that the carbon plate of the forefoot part 20 is divided into an inner support area 201, an outer support area 202 and a middle ejection area 203. The separate and independent designs can optimize or improve their respective functions and improve the performance of the structure. For example, the curvature of the curved portion 205 of the middle ejection area 203 can be increased, so that a higher elastic force can be provided to help the runner's movement. The inner support area 201 can be designed to be relatively flat, and connected to the toe support area 2021 as a whole, and a flatter and larger area structure can provide good support performance. The outer support area 202 corresponds to the outer side of the sole, and the strip-like structure cooperates with the outer side of the foot design, which has good elastic buffering and support effects, which helps the runner's movement.

[0046] Furthermore, in this embodiment, the inner support area 201 or the outer support area 202 is provided with a toe support area 2021, and the inner support area 201 is provided with the toe support area 2021 as an example. When a runner is running, the outer side of the forefoot touches the ground first and then touches the inner side of the forefoot and the mid-waist heel, so the elasticity of the outer support area 202 needs to be relatively good, while the support performance of the inner support area 201 is relatively good, so that the posture required by the runner during exercise can be adapted to form a matching effect, which is beneficial to the running exercise.

[0047] If the outer support area 202 has a toe support area 2021, it can be a casual shoe with more balanced performance and comfortable wearing. The forefoot part 20 can provide good support and has elasticity for walking, thereby improving practicality.

[0048] like Figure 1 and Figure 2 As shown, in this embodiment, the inner side edge of the foot of the medial support area 201 is provided with a curved and extended first edging area 206, and the outer side edge of the foot of the lateral support area 202 is provided with a curved and extended second edging area 207. The first edging area 206 and the second edging area 207 are convex structures on the edge of the forefoot 20, so that when the shoe carbon plate is assembled and fitted, a corresponding side edging fixing effect can be formed. Specifically, the edge of the shoe carbon plate 1 is exposed to the midsole and bent upward, which greatly avoids the phenomenon of sprains or sprains that are easy to occur to runners during exercise. At the same time, the irregular appearance of carbon fiber can reduce the weight of carbon fiber, thereby controlling the weight of the finished shoe.

[0049] Furthermore, if Figure 1 and Figure 2As shown, in this embodiment, a third edge region 101 is provided on at least one side of the arch region between the rear sole portion 10 and the forefoot. The design of the third edge region 101 can form a stable positioning installation, and the edge of the shoe carbon plate is exposed on the midsole and bent upward, which greatly avoids the occurrence of sprains or sprains that are easy to occur to runners during exercise.

[0050] The hardness of the middle ejection area 203 in this embodiment is greater than the hardness of the inner support area 201 or the outer support area 202, so that the middle ejection area 203 has good elastic properties. For example, the hardness of the middle ejection area 203 may be 92D, while the hardness of the inner support area 201 or the outer support area 202 may be 86D, forming a difference of 6D to optimize their respective performances.

[0051] like Figure 1 and Figure 2 As shown, in this embodiment, a bending notch 102 is provided between the third edging area 101 and the first edging area 206 or between the third edging area 101 and the second edging area. The bending notch 102 is designed at the position where the carbon plate for shoes bends when the human foot walks, so as to facilitate the bending of the forefoot. At the same time, the carbon plate for shoes provides corresponding elastic force, which facilitates movement and improves practicality.

[0052] Embodiment 2

[0053] like Figure 3 , Figure 4 and Figure 5 As shown, this embodiment provides a sole, including a carbon plate 1 and a shoe midsole 2, the carbon plate 1 is the shoe carbon plate 1 described in the first embodiment; the shoe midsole 2 includes an upper midsole 21 and a lower midsole 22, and a contour groove 221 for placing the carbon plate 1 is provided on the joint surface of the upper midsole 21 or the lower midsole 22. A wear-resistant outsole can be designed on the bottom surface of the lower midsole 22, that is, a layer of outsole (rubber sole or silicone sole, etc.) can be attached, or the bottom surface of the lower midsole 22 can be designed as a wear-resistant structure, for example, the density is increased, anti-slip patterns are designed, etc., to form a shoe bottom layer structure.

[0054] Specifically, the shoe midsole 2 is designed by clamping the carbon plate 1 by the upper midsole 21 and the lower midsole 22, and the shoe midsole 2 can be made of nylon elastomer foam, which has good comfort and resilience. The corresponding contour groove 221 can be designed on the upper midsole 21 or the lower midsole 22 according to the contour of the carbon plate 1, so that the carbon plate 1 can be fitted and attached to the shoe midsole 2 to achieve the purpose of fixed installation. In this way, the edge of the carbon plate 1 is exposed to the midsole and bent upward, which greatly avoids the phenomenon of sprains and sprains that are easy to occur to runners during exercise. At the same time, the irregular appearance of carbon fiber can reduce the weight of carbon fiber, thereby controlling the weight of the finished shoe.

[0055] Furthermore, if Figure 4As shown, in this embodiment, a first window 222 is provided at the forefoot of the lower midsole 22, and a second window 223 is provided at the rear foot of the lower midsole 22. The first window 222 is asymmetrically designed at the forefoot, so that the structural design of the first window 222 can be better matched. Specifically, a connection point is designed at the arch between the first window 222 and the second window 223, and the first window 222 is designed in the middle to avoid the bending portion 205 of the forefoot, and the design of the carbon plate 1 is matched, so that the middle ejection area 203 is located on the first window 222, and the medial support area 201 and the lateral support area 202 are correspondingly located on both sides, so that a support area from the forefoot to the rear foot is formed for the lateral support area 202, which is beneficial to the support force and buffering effect of the entire lateral side.

[0056] Similarly, the second window 223 is located at the rear sole and the arch of the foot, so that an inwardly collapsed buffer can be formed, making the landing force more stable and reducing the recoil or rebound to the foot, which is very helpful for running.

[0057] like Figure 3 As shown, in this embodiment, a contour edging 224 covering the bottom of the upper midsole 21 is provided at the rear sole of the lower midsole 22; the design of the contour edging 224 can cover and connect the rear heel of the upper midsole 21, thereby improving the structural stability between the upper midsole 21 and the lower midsole 22.

[0058] Furthermore, if Figure 3 As shown, a buffer hole 23 is provided between the arch area of ​​the upper midsole 21 and the lower midsole 22, that is, a hollow buffer structure is formed in the arch area. The design of the buffer hole 23 can provide good buffering performance, which helps runners to exercise.

[0059] Furthermore, if Figure 3 As shown, the hardness of the lower midsole 22 is greater than that of the upper midsole 21; the forefoot portion 20 of the lower midsole 22 is provided with a raised arc 225. The upper midsole 21 and the lower midsole 22 are nylon elastomer foams, and the hardness of the upper midsole 21 can be 43C, which can provide wearing comfort and high rebound effects; the hardness of the lower midsole 22 is 45C, which can provide high compression and high shock absorption effects, and the density of the nylon elastomer foam can be 0.13g / cm3 (if it is a lightweight midsole, the density can be: 0.16g / cm3). Therefore, with the hardness difference of the forefoot portion 20 of the carbon plate 1, the force on the midsole and the force-generating habits of the runner in the three states of landing, exerting force and starting can be well matched, and good benefits can be provided to the runner.

[0060] like Figure 3 and Figure 4As shown, in this embodiment, the contour groove 221 is arranged on the joint surface of the upper midsole 21, and the forefoot area of ​​the lower midsole 22 is provided with a limiting groove 226 for placing the middle ejection area 203 of the carbon plate 1. Through the design of the limiting groove 226, the upper midsole 21 and the lower midsole 22 can be clamped and limited to ensure the bending force of the middle elastic area and provide a stable elastic force.

[0061] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
