The mounting groove 11 is provided with an elastic plate 30, and the front end of the elastic plate 30 is disposed corresponding to the front end of the metatarsal bones of the foot, and the rear end of the elastic plate 30 extends to the rear end of the half sole portion 101, specifically, to a position near the arch portion 102. The elastic plate 30 is provided with a cover plate 20, the cover plate 20 is embedded in the mounting groove 11, the lower surface of the cover plate 20 is pressed against the upper surface of the elastic plate 30, and the upper surface of the cover plate 20 is flush with the upper surface of the midsole 10. In the present invention, the cover sheet 20 may be further adhered to the mounting groove 11 by an adhesive, thereby confining the elastic plate 30 to the mounting groove 11. In the present invention, the hardness of the elastic plate 30 is greater than that of the midsole 10, and the hardness of the elastic plate 30 is greater than that of the cover plate 20. The cover plate 20 and the midsole 10 have smaller hardness, more comfortable touch feeling, and the elastic plate 30 has larger hardness, and can provide stronger resilience force when bending, thereby assisting the athlete to realize the ground stepping action more forcefully and improving the long jump performance.

As a preferred mode of the present invention, the upper surface of the elastic plate 30 forms a first arch-shaped protrusion 31 and a second arch-shaped protrusion 32, the lower surface of the elastic plate 30 forms a first bar-shaped groove 33 corresponding to the first arch-shaped protrusion 31, the lower surface of the elastic plate 30 forms a second bar-shaped groove 34 corresponding to the second arch-shaped protrusion 32, the first arch-shaped protrusion 31 and the second arch-shaped protrusion 32 each extend from the front end to the rear end of the elastic plate 30, the first arch-shaped protrusion 31 and the second arch-shaped protrusion 32 divide the elastic plate 30 into a first region 35, a second region 36 and a third region 37 which are arranged along the direction of the outer side 105 of the inner side 104, the first region 35 is arranged corresponding to the first metatarsal bone, the second region 36 is arranged corresponding to the second metatarsal bone and the third metatarsal bone, and the third region 37 is arranged corresponding to the fourth metatarsal bone and the fifth metatarsal bone. By adopting the structure, when the elastic plate 30 is pressed, the first arch-shaped bulge 31 and the second arch-shaped bulge 32 respectively displace towards the first strip-shaped groove 33 and the second strip-shaped groove 34, so that the elastic plate 30 also has certain deformation in the direction of the outer side 105 of the inner side 104, and when the elastic plate rebounds, the elastic plate can drive the inner side 104 and the outer side 105 of the sole body to shrink towards the position between the inner side 104 and the outer side 105, so that the sole body is more attached to the foot, the accumulated force is assisted to be tightened by the foot, and the force is better exerted. In addition, the first arch-shaped protrusions 31 and the second arch-shaped protrusions 32 extend in the front-rear direction, play a role similar to that of reinforcing ribs, the strength of the elastic plate 30 is better, and resilience force can be increased after bending, so that a player can more forcefully step on the ground to leave the ground.
As a preferable mode of the present invention, the cover 20 is provided with a first receiving groove 21 corresponding to the first arch-shaped protrusion 31, the cover 20 is provided with a second receiving groove 22 corresponding to the second arch-shaped protrusion 32, the mounting groove 11 penetrates to the end surface of the inner side 104 of the midsole 10 and forms a notch 12 on the midsole 10, and the elastic plate 30 forms an extension supporting part 38 extending into the notch 12 corresponding to the notch 12. Preferably, the midsole 10 is provided with a first positioning protrusion 13 and a second positioning protrusion 14 corresponding to the first positioning protrusion 33 and the second positioning protrusion 34 in the mounting groove 11, and the first positioning protrusion 13 and the second positioning protrusion 14 are respectively embedded in the first positioning protrusion 33 and the second positioning protrusion 34, and by setting the first positioning protrusion 13, the second positioning protrusion 14, the first storage groove 21 and the second storage groove 22, the sliding of the elastic plate 30 in the direction of the outer side 105 of the inner side 104 can be limited, so that the elastic plate 30 can apply the elastic force to the foot more accurately.
As a preferred mode of the present invention, the elastic plate 30 is a carbon fiber plate, a nylon plate or a TPU plate, and the thickness of the elastic plate 30 is 1mm to 3mm.
As a preferred mode of the present invention, the shore D hardness of the elastic plate 30 is 65 to 75, the shore C hardness of the midsole 10 is 45 to 55, the shore C hardness of the cover 20 is 45 to 55, and the shore a hardness of the outsole 40 is 55 to 64.
In a preferred embodiment of the present invention, the midsole 10 and the cover 20 are made of the same material, the midsole 10 is made of EVA or ETPU, and the outsole 40 is made of rubber.
