[0002] There are many racing shoes in life, and the styles of the soles of the male and female racing shoes are usually consistent, and the heel structures of the soles are also usually consistent. However, the body functions of the female and male racers are not the same, for example, the calf muscles of the female are far less developed than those of the male, and the female cannot run for a long time by using the forefoot, and when the middle and rear feet land, the female sole usually needs stronger support compared with the male, and similarly, the female racing shoe also needs better shock absorption, so that the heel landing is less tired.
[0003] On the market, due to the lack of heel wrapping performance, the support, comfort and shock absorption performance of the shoe need to be further improved.

PREFERRED EMBODIMENT
[0037] The front, rear, upper and lower directions of the utility model are referenced to the directions in the normal use state of the shoes.
[0038] This utility model relates to a women's racing shoe, comprising an upper and a sole connected together. The sole of this utility model, as shown... Figure 1 and Figure 3 As shown, the invention includes a shoe support plate 1, a foamed sole 2, and an anti-slip sole 3. The shoe support plate 1 covers the interior of the foamed sole 2. During processing, the shoe support plate 1 is placed at a predetermined position in the foaming mold of the foamed sole 2, and then the foaming operation of the foamed sole 2 is performed. In this invention, the position of the shoe support plate 1 relative to the interior of the foamed sole 2 can be set according to actual needs. In this embodiment, the shoe support plate 1 is located in the middle layer position in the thickness direction of the foamed sole 2. The anti-slip sole 3 is fixed to the bottom surface of the foamed sole 2.
[0039] In this invention, the front and rear keel drop of the women's racing shoe is 8-10mm. Compared with the conventional keel drop of about 5mm, the increased keel drop of this invention makes the transition smoother and the running more efficient during the high-frequency repeated bending of the forefoot (foot lifting and falling).
[0040] In this invention, the shoe support plate 1 is a rigid plate. A rigid plate is a plate that increases the rigidity of the shoe sole. The shoe support plate 1 is typically harder than the foamed sole 2. The shoe support plate 1 can be made of carbon fiber, nylon, or TPU, etc., as long as it effectively increases the rigidity of the shoe sole.
[0041] In this embodiment, a carbon fiber plate is used as an example to illustrate the shoe support plate 1. Figure 2 As shown, the shoe support plate 1 includes a forefoot portion 11, an arch portion 12, and a heel portion 13. The forefoot portion 11 corresponds to the forefoot of the human foot, the arch portion 12 corresponds to the arch of the human foot, and the heel portion 13 corresponds to the heel of the human foot. The arch portion 12 is located between the forefoot portion 11 and the heel portion 13.
[0042] The heel portion 13 has a three-dimensional split structure, which includes a downward-folding elastic support strip 131, and a first support strip 132 and a second support strip 133 located on both sides of the downward-folding elastic support strip 131. A first groove 134 is formed between the first support strip 132 and the downward-folding elastic support strip 131, and a second groove 135 is formed between the second support strip 133 and the downward-folding elastic support strip 131. The ends of the downward-folding elastic support strip 131, the first support strip 132, and the second support strip 133 are all free ends. The downward-folding elastic support strip 131 is folded down, and the free end of the downward-folding elastic support strip 131 is located below the support surface of the shoe support plate 1. The downward-folding elastic support strip 131 and the support surface of the shoe support plate 1 form an acute angle. The downward-folding elastic support strip 131 is set corresponding to the middle of the human heel. The first support strip 132 and the second support strip 133 are arranged in an inverted V-shape to form a support wrapping surface that fits the structure of the human calcaneus.
[0043] The first support bar 132 is located at the outer side, and the second support bar 133 is located at the inner side; the inclination angle of the first support bar 132 with the horizontal plane is greater than the inclination angle of the second support bar 133 with the horizontal plane. Preferably, the free end of the downwardly-inclined elastic support bar 131 is formed with a flat section 1311, so that the rebound and the like can be more smoothly achieved, and the repeated force stepping can be facilitated.
[0044] The front palm part 11 has a wave-shaped support part 4 arranged at the middle palm position of the front palm part 11, and the wave-shaped support part 4 is arranged in a concave-convex manner along the length direction of the shoe support plate 1, and has a wave shape. Figure 1 As shown in the drawings, the shoe support plate 1 is formed with a first concave-convex curved surface 41 on the top surface of the wave-shaped support part 4, and the first concave-convex curved surface 41 is part of the top surface of the shoe support plate 1; the shoe support plate 1 is formed with a second concave-convex curved surface 42 on the bottom surface of the wave-shaped support part 4, and the second concave-convex curved surface 42 is part of the bottom surface of the shoe support plate 1, the convex surface of the first concave-convex curved surface 41 corresponds to the convex surface of the second concave-convex curved surface 42, and the concave surface of the first concave-convex curved surface 41 corresponds to the concave surface of the second concave-convex curved surface 42. The spacing between the first concave-convex curved surface 41 and the second concave-convex curved surface 42 is uniform. The thickness between the first concave-convex curved surface 41 and the second concave-convex curved surface 42 is the thickness of the shoe support plate 1. The thickness of each part of the shoe support plate 1 is uniform. The highest point of the convex surface of the second concave-convex curved surface 42 is higher than the height of the overall support surface of the shoe support plate 1, and the lowest point of the concave surface of the first concave-convex curved surface 41 is lower than the height of the overall support surface of the shoe support plate 1. In this embodiment, the wave transverse direction of the wave-shaped support part 4 is consistent with the arrangement direction of the toe bones. Compared with the width direction of the shoe sole, the arrangement direction of the metatarsal bones is inclined, and the force line of the front palm is also inclined when the front palm is bent. By setting the wave transverse direction of the wave-shaped support part 4 to be consistent with the arrangement direction of the toe bones, the force line of the human body during running is more matched, and the force transmission is more smooth.
[0045] In the utility model, the wave-shaped support part 4 can also extend from the middle palm position of the front palm part 11 to the middle front palm position. The setting position of the wave-shaped support part 4 can be set according to actual conditions.
[0046] This invention relates to a shoe support plate 1, which uses a wave-shaped carbon fiber plate. When subjected to downward pressure from the foot, the wave-shaped support part 4, based on the force distribution of its wavy surface, not only propels forward but also extends and deforms longitudinally (along the length of the shoe) when the foot pushes off. Upon lifting the foot, the deformed wave-shaped support part 4 rebounds, generating an upward rebound force. Thus, the wave-shaped support part 4 creates a dual force structure, providing a good forward and upward thrust to the foot. The shoe support plate 1 not only offers good support but also generates a good thrust during use, making exercise more effortless and comfortable. Simultaneously, the concave and convex surfaces of the wave-shaped support part 4 provide an indirect massage effect on the foot, making exercise more comfortable and minimizing foot soreness.
[0047] As a preferred embodiment, such as Figure 1 As shown, the forefoot portion 11 includes a wave-shaped support portion 4 and a forefoot support portion 112 located at the front end of the wave-shaped support portion 4. The forefoot support portion 112 curves forward. Specifically, the front end of the wave-shaped support portion 4 is a wave-shaped concave portion, that is, the front end of the wave-shaped support portion 4 is concave downward, forming an upwardly and forwardly curved front edge 43. The forefoot support portion 112 and the front edge 43 of the wave-shaped support portion 4 are smoothly connected. The upward angle of the forefoot support portion 112 and the upward angle of the front edge 43 of the wave-shaped support portion 4 are smoothly transitioned. The forefoot portion 11 has a higher upward angle than conventional shoes on the market. In this way, a continuous rolling thrust is generated during exercise. Compared with the traditional running method that relies on strides to generate force, the rolling thrust of this invention makes running more energy-efficient and more comfortable.
[0048] As a preferred embodiment, such as Figure 2 and Figure 3 As shown, a perforation 111 is provided in the middle of the forefoot portion 11, and a U-shaped structure is formed around the perforation 111. This U-shaped structure still provides good support for the forefoot, while the perforation 111 distributes pressure. It also appropriately reduces the rigidity of the carbon plate, facilitating propulsion based on the shoe's rolling motion. This makes the carbon plate structure more flexible, avoiding rigidity and further improving comfort.
[0049] Specifically, such as Figure 2As shown, the wave-shaped support portion 41 is formed with a first wave-shaped support portion 41 and a second wave-shaped support portion 42 on both sides of the hollow hole 111. The first wave-shaped support portion 41 and the second wave-shaped support portion 42 are respectively a part of the above-mentioned U-shaped structure. The first wave-shaped support portion 41, the hollow hole 111 and the second wave-shaped support portion 42 are sequentially arranged along the width direction of the shoe support plate 1. In this way, the hollow hole 111 can cut off the force transmission of the first wave-shaped support portion 41 and the second wave-shaped support portion 42 in the width direction of the sole support plate 1. The first wave-shaped support portion 41 and the second wave-shaped support portion 42 can respectively independently react, better disperse the weight applied by the foot, and reduce the pressure point. The ergonomic design, the partitioned independent design of the first wave-shaped support portion 41 and the second wave-shaped support portion 42 can self-adaptively uniformly support each part of the foot, and relax the muscles of the foot. At the same time, the U-shaped structure can also ensure the overall supportability of the forefoot 1, and to a certain extent, the force can be transmitted in the width direction and in the length direction.
[0050] Further, as shown in Figure 2 and Figure 3 , the forefoot 11 is provided with a support tongue 113 inside the hollow hole 111. The rear end of the support tongue 113 is connected to the arch 12, and the front end is a free end. The setting of the support tongue 113 can further improve the support rigidity and rolling transmission of the wave-shaped support portion 4. It is helpful for the rolling force of the sole, the rolling feeling is stronger, and the running is more labor-saving, comfortable and comfortable.
[0051] As a preferred embodiment, the arch 12 is provided with an inner reinforcing rib 121 and an outer reinforcing rib 122. The inner reinforcing rib 121 is arranged corresponding to the direction of the medial longitudinal arch of the human body, and the inner reinforcing rib is arranged protruding downward on the bottom surface of the arch 12; the outer reinforcing rib 122 is arranged corresponding to the direction of the lateral longitudinal arch of the human body, and the outer reinforcing rib 122 is arranged protruding downward on the bottom surface of the arch 12. In this way, better arch support can be provided.
[0052] Further, the inner side of the arch 12 extends along the width direction of the sole to form an inner arch support portion 123, which is matched with the medial longitudinal arch of the human body, so as to strengthen the medial arch support, and further make the whole arch realize stable support.
[0053] The utility model discloses a female special speed -race shoes sets up the support board 1 of shoe, improves the rigidity of shoe sole, and the shock attenuation is better, improves the heel difference (keel drop) of shoe sole, makes the transition of shoes better, opens the hollow hole 111, and the rigidity of carbon plate is properly reduced, and then combines the wave type support part 4, and the design of the forefoot is upturned, all are favorable to the shoe rolling power and push forward, make the comfort of shoes better when moving.
[0054] Table 1 is the comparative test data of the sole of the female special speed -race shoes of the utility model
[0055]
[0056] From table 1, the peak acceleration (average) of the forefoot and heel of the sole of the utility model is obviously superior to the speed -race shoes on the market, and the resilience is better.
[0057] The peak acceleration of the heel of the utility model can be as low as 8.3g.
[0058] It should be noted that the shoe support plate of the utility model can be provided with a hollow area in the non-stress area to reduce the weight, and the specific hollow position can be set according to actual needs, such as being provided between each toe or the periphery of the toe.
