Modular sole structure

Abstract

The present invention provides a modular sole structure, including a sole and at least one convex arranged on the sole. An anti-wear block, which is removable and matches with the convex, is mounted at the bottom of the convex near the ground, The modular sole structure provided by the invention can form a modular sole structure by mounting a removable anti-wear block to the sole. When the anti-wear block is worn out, a new anti-wear block can be replaced. In this way, the user can fine adjust his walking posture, and thus reduce the wearing-out of the sole structure. Because of this, the life-span of the shoes is prolonged, and the undesirable walking posture caused by the wearing-out of the sole can be avoided; by replacing the removable anti-wear block, the user will not have to frequently replace new shoes and economic loss is avoided.
