[0042] Reference Figures 1-6 A light racing shoe sole, comprising a big sole 1, the big sole 1 has a mounting cavity 11, a midsole plate 2 is mounted in the mounting cavity 11, the midsole plate 2 is provided with a ball area 21, an arch area 22 and a heel area 23 corresponding to the positions of the ball part, the arch part and the heel part of the foot, by dividing the midsole plate 2 into three different areas, the condition of the sole can be adjusted, a plurality of convex strips 24 extending around are arranged in the ball area 21, the arch area 22 and the heel area 23, the convex strips 24 can be made of any one of polyurethane, thermoplastic elastomer and rubber material with buffering and elastic recovery ability, the convex strips 24 are closed at both ends to form a grid part with a groove, a plurality of convex strips 24 form a honeycomb pattern on the midsole plate 2, the honeycomb pattern not only can provide sufficient support but also can reduce the overall weight of the sole, thereby realizing light design;

[0043] The elastic supporting component 4 is arranged on the middle bottom plate 2, and the elastic supporting component 4 can improve the buffering effect. The elastic supporting component 4 is arranged in a plurality of and spaced distribution in the groove. The elastic supporting component 4 comprises a bearing seat 41, the bearing seat 41 is provided with a containing groove 411, and the containing groove 411 is connected with an elastic element 42. The elastic element 42 is deformed in the containing groove 411, absorbs and disperses the impact force, thereby effectively reducing the impact on the foot. The other end of the elastic element 42 is connected with a buffer pad 43. The elastic element 42 is a pressure spring or a elastic spring in the prior art. The buffer pad 43 can be made of any one of polyurethane, thermoplastic elastomer and rubber material which has buffering and elastic recovery ability.

[0044] The inner layer plate 3 is connected with the buffer pad 43, and the inner layer plate 3 is located on the side close to the foot.

[0045] The large bottom 1 is provided with a hollow part 13 on the side facing the ground, which is used to reduce the weight and increase the flexibility, improve the light weight degree of the whole sole, and the hollow structure increases the deformation space of the sole, so that the sole can better adapt to the dynamic change of the foot when being stressed. The large bottom 1 is also provided with anti-skid lines 14 on the side facing the ground, which are located on one side of the hollow part 13 and are used to provide the gripping force and anti-skid performance. The anti-skid lines 14 are located at the front end of the sole, which can effectively increase the friction between the sole and the ground and prevent slipping.

[0046] Based on the above structure, the middle bottom plate 2 is installed on the large bottom 1, so that the side with the convex strip 24 is located on the side of the middle bottom plate 2 away from the large bottom 1, and the elastic supporting component 4 on the middle bottom plate 2 is connected with the inner layer plate 3. When the inner layer plate 3 is displaced due to impact, it will abut against the top end of the convex strip 24, so that the middle bottom plate 2 can be supported by the plurality of convex strips 24, and the weight of the whole sole can be reduced while providing the supporting effect, thereby realizing the light weight of the sole. Since the middle bottom plate 2 and the inner layer plate 3 are connected by the elastic supporting component 4, when the foot is impacted by the ground, the impact force is first transmitted to the inner layer plate 3. Since the inner layer plate 3 is connected with the buffer pad 43, the buffer pad 43 will extrude the elastic element 42 under the action of the impact force, so that the elastic element 42 is deformed in the containing groove 411, absorbs and disperses the impact force, thereby effectively reducing the impact on the foot. The bearing seat 41 provides a stable supporting basis for the elastic element 42, so that the elastic element 42 will not be excessively deviated when bearing the pressure, thereby improving the stability and supportability. Through the cooperation of the convex strip 24 with the honeycomb pattern on the middle bottom plate 2 and the elastic supporting component 4, the weight of the sole can be reduced, and the comfort and sports performance of the sole can be improved, thereby solving the problem of single performance of the traditional sole.

[0047] In one embodiment, referring to Figure 1 , Figure 2、 Figure 3 and Figure 6 The arch area 22 is located between the sole area 21 and the heel area 23, the honeycomb cells in the arch area 22 gradually increase in size, providing better stability and transition performance, the area of the mesh part located in the arch area 22 is larger than that of the mesh part located in the sole area 21, the honeycomb cells in the sole area 21 are smaller and denser, providing stronger support and better rebound performance, the area of the mesh part located in the arch area 22 is smaller than that of the mesh part located in the heel area 23, the honeycomb cells in the heel area 23 are the largest and are distributed sparsely, providing better shock absorption;

[0048] The propulsion phase of running mainly relies on the forefoot. Smaller and denser honeycomb cells can provide more concentrated support, so setting smaller cells in the sole area 21 can have more support points in a unit area, effectively resisting the reaction force from the ground and reducing fatigue;

[0049] The arch area 22 plays a transitional role in the process of walking or running, and the larger cells have more deformation space when subjected to pressure, which can better adapt to the natural twisting and bending actions of the foot during the transition from the heel to the forefoot;

[0050] The heel area 23 produces a large impact force when the heel hits the ground during walking or running, and better shock absorption is needed to protect the foot and joints. The largest and sparsely distributed honeycomb cells can provide more buffer space, and when the heel hits the ground, the larger honeycomb cells can be fully compressed to absorb and disperse the impact force.

When the midsole plate 2 is installed in the mounting cavity 11, the bottom end face of the midsole plate 2 abuts against the air cushion part 121. The multiple air cushion parts 121 jointly act on the midsole plate 2, providing more uniform and comprehensive support for the midsole plate 2. When the midsole plate 2 abuts against the air cushion part 121, the air cushion part 121 can exert an upward supporting force on the midsole plate 2 at different positions, so that the midsole plate 2 is not easily deformed when subjected to foot pressure. When standing or walking, it can help maintain the normal physiological structure and posture of the foot, provide good support for the foot, reduce foot fatigue, and the impact force when landing during exercise can be dispersed and absorbed by multiple air cushion parts 121, effectively reducing the impact force on the foot, knee and joints, and reducing the risk of sports injuries.
