Abstract

The utility model discloses a corrosion resistant apparatus for shoe soles, which comprises a surface layer made of soft TR material, a corrosion resistant layer made of EVA material, a pad layer and a bottom layer from top to bottom. Upward convexities are arranged at the upper surface of the corrosion resistant layer. Cavities with downward openings are arranged inside the convexities. The lower surface of the surface layer is equipped with pits matching with the convexities arranged at the upper surface of the corrosion resistant layer. The surface layer is closely adhered to the corrosion resistant layer. When the sole with the above corrosion resistant apparatus touches the ground, hollow "EVA convexities" start to be compressed. In the compression process, the contact stress area of the EVA convexities increases with the compression degree thereof as well as the reaction force, thus is comfortable in wearing. The sporting performance of the sole is also increased. The hardness of the sole is adjusted by arranging the shape and density of the EVA convexities, thereby satisfying the requirements of various sports according to the stress requirements of different foot regions.
