[0006] Preferably, the top end of the shoe tip is concave to form a plurality of grooves, and each of the grooves is wavy.

[0007] Preferably, a plurality of anti-slip blocks are provided at the bottom end of the shoe tip, anti-slip grooves are provided between the plurality of anti-slip blocks, and blind holes are provided at the bottom ends of the anti-slip blocks near the center of the shoe tip.

[0008] Preferably, the round cover is in the shape of a hollow hemisphere, and the top end of the round cover extends beyond the upper end surface of the heel.

[0009] Preferably, the support column is a jujube-shaped structure with a hollow interior, and the top and bottom ends of the support column are both arranged to be flat.

[0010] Preferably, the reinforcing ribs are arranged in a spiral shape from top to bottom.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0012] 1. The utility model provides a cavity, vertical plates, a rebound cavity and a buffer mechanism. The rebound cavity formed between the vertical plates in the cavity is engaged with the buffer mechanism, and the round cover is supported by the cylinder and the support column in the round cover, so that the overall buffering performance of the heel is increased, the rebound performance is improved, and the wearing is more comfortable.

[0013] 2. The utility model provides a support column, a reinforcement plate and reinforcement ribs. The reinforcement plate at the lower section of the outer edge of the support column ensures that the support column is always placed in the center of the circular cover, thereby avoiding the phenomenon of displacement after long-term use. The reinforcement ribs inside the support column can increase the rebound performance of the support column and improve the service life of the sole. BRIEF DESCRIPTION OF THE DRAWINGS
