Therefore, they should not be construed as limitations on this utility model. Example

[0033] Reference Figure 1 and Figure 2A support plate 10 for shoe soles, the support plate 10 being a rigid TPU plate, nylon plate, or carbon plate, comprising a base 108, a first support portion 101, a second support portion 102, and a support platform 103; the base 108 is positioned corresponding to the midfoot position, with the side corresponding to the outer side of the foot being the outer side and the side corresponding to the inner side of the foot being the inner side; the first support portion 101 is disposed on the inner side of the base 108 and extends toward the inner side of the foot; the second support portion 102 is erected on the upper surface of the first support portion 101, and the connection between the second support portion 102 and the first support portion 101 is located on or inside the edge of the first support portion 101 near the base 108; the support platform 103 is at least a part of the first support portion 101, connected to the wall of the second support portion 102 near the inner side of the foot and extending toward the inner side of the foot.

[0034] Specifically, when the connection between the second support portion 102 and the first support portion 101 is located on the edge of the first support portion 101 near the base 108 (e.g.) Figure 1 As shown, the support platform 103 coincides with the first support part 101, or the support platform 103 is the same as the first support part 101; when the connection between the second support part 102 and the first support part 101 is located on the inner side of the edge of the first support part 101 near the base 108, the support platform 103 is part of the first support part 101. By setting the support platform 103 on one side of the second support part 101, the support area is increased, and the horizontal and three-dimensional supports are coordinated, thereby enhancing the torsional resistance and support performance of the midfoot.

[0035] Further, the support plate 10 includes a first extension 104, a second extension 105, a third extension 106, and a fourth extension 107. The first extension 104 is connected to the base 108 along the inner side near the base 108 and extends toward the forefoot. The second extension 105 is connected to the base 108 along the outer side near the base 108 and extends toward the forefoot. The third extension 106 is connected to the base 108 along the inner side near the base 108 and extends toward the hindfoot. The fourth extension 107 is connected to the base 108 along the outer side near the base 108 and extends toward the hindfoot. The base 108, the first support 101, the second support 102, the first extension 104, the second extension 105, the third extension 106, and the fourth extension 107 are integrally formed and are generally "X" shaped.

[0036] The first extension 104 is longer than the second extension 105. The first extension 104 extends to the big toe, where the big toe and its vicinity bear more force, which can enhance support. The second extension 105 is short, which can prevent the second extension 105 from hitting the metatarsal head of the little toe when the forefoot lands during exercise, thus avoiding discomfort.

[0037] Reference Figure 3 The front end of the first extension 104 is raised, and the rear ends of the third extension 106 and the fourth extension 107 are raised, which can provide instantaneous cushioning and assistance. The base 108 can also be configured to extend upward in an arc shape from the middle to both the inner and outer sides, which can further increase the rebound force of the support plate and better provide assistance. During movement, based on the lever principle, when the forefoot of the support plate 10 is pressed down, the hindfoot of the support plate 10 is lifted forward and upward, and under the rebound force of the support plate 10 itself, it drives the hindfoot of the human body upward, forming an instantaneous cushioning and significant assistance to the hindfoot of the human body; similarly, when the hindfoot of the support plate 10 is pressed down, the forefoot of the support plate 10 is lifted backward and upward, and under the rebound force of the support plate 10 itself, it drives the forefoot of the human body upward, forming an instantaneous cushioning and significant assistance to the forefoot of the human body.

[0038] Furthermore, several reinforcing ribs are evenly distributed on the upper surface of the support plate 10, as shown in the reference. Figure 1 The reinforcing ribs include a first reinforcing rib 109, a second reinforcing rib 110, and a third reinforcing rib 111. The first reinforcing rib 109 extends from the first extension 104 to the third extension 106. The second reinforcing rib 110 is V-shaped, with its two sides extending from the first extension 104 and the second extension 105 respectively to the base 108 where they converge. The third reinforcing rib 111 is disposed on the upper surface near the outer side of the base 108. By providing reinforcing ribs, torsional resistance can be further enhanced, and a better supporting function can be provided. Example

[0039] Reference Figures 4-7 A shoe sole includes a midsole 20 and a rubber outsole 30. The midsole comprises an upper midsole 201 and a lower midsole 202. A support plate 10 is located between the upper midsole 201 and the lower midsole 202. The bottom surface of the upper midsole 201 has a groove 2011 that matches the shape of the support plate 10. The upper midsole 201 is less hard than the lower midsole 202. In the market, the upper midsole 201 is often made of soft, high-density material, while the lower midsole 202 is often made of harder MD (medium-density) outsole.

[0040] The lower insole 202 has a hollowed-out portion 2021 corresponding to the forefoot, and the rubber outsole 30 at least covers the hollowed-out portion 2021, and the rubber outsole 30 plays a role in anti-slip and stability.

[0041] The lower midsole 202 has an upwardly extending TPU reinforcement sheet 40 on the outer side of the midfoot and / or forefoot, which can stabilize the human foot during strenuous exercise and thus avoid foot injury.

[0042] It should be understood that the above are only preferred embodiments of the present utility model, and the protection scope of the present utility model is not limited to the above embodiments. All technical solutions that fall within the scope of the present utility model are protected by the present utility model.
