Referring to fig. 1 and 2, fig. 1 is a schematic view of an athletic shoe according to the present utility model, and fig. 2 is a longitudinal sectional view of the athletic shoe shown in fig. 1.

As shown in fig. 1 and 2, the sports shoe provided by the utility model comprises a sole 10 and a vamp 20, wherein the edge of the vamp 20 is fixed with the edge of the sole 10.

Referring again to fig. 2-7, the sole of the present utility model includes a midsole 11, a support stabilizer 12, and an outsole 13, with the support stabilizer 12 being interposed between the midsole 11 and the outsole 13.

The upper surface of the middle waist part of the midsole 11 is provided with a soft protuberance 14 which is attached to the foot bow, the bottom surface is provided with a downward convex arc protuberance 15, the soft protuberance 14 protrudes upwards, and the arc protuberance 15 protrudes downwards. In this embodiment, the arc-shaped protrusion 15 protruding downward is a hemispherical protrusion.

As shown in fig. 3, the supporting stabilization plate 12 is in a sheet structure, and the center of the supporting stabilization plate is raised upwards to form a raised portion, the raised portion is provided with a hollowed portion 16 penetrating through the raised portion, and the hollowed portion 16 is matched with the root edge of the arc-shaped protrusion 15, so that the supporting stabilization plate 12 can be sleeved on the root of the arc-shaped protrusion 15. The supporting stabilizer plate 12 has four bar-shaped extending portions, the outer edges of the bar-shaped extending portions are arc-shaped, and the four bar-shaped extending portions are respectively arranged on two sides of the supporting stabilizer plate 12 in the length direction and are symmetrically arranged in pairs. The two strip-shaped extending parts at one side are a first extending part 121 and a second extending part 122 respectively, the first extending part 121 faces the inner side direction of the sole, the second extending part 122 faces the outer side direction of the sole, and the length of the first extending part 121 is smaller than that of the second extending part 122. Thus, when the midsole, the bearing stabilizer plate and the outsole are integrally formed, the four strip-shaped extension parts can be reliably fixed in the midsole and the outsole, and materials are saved.

The top surface of the outsole 13 is provided with a concave part 17 at the position corresponding to the arc-shaped protrusion 15, a gap is arranged between the concave part 17 and the outer surface of the arc-shaped protrusion 15, a space is reserved for the up-and-down movement of the arc-shaped protrusion of the lower bulge on the midsole, the shock absorption performance is improved, and the comfort is improved.
