Improvement of the midsole structure of the shoe

Abstract

This invention discloses an improvement to the midsole structure of a shoe, suitable for high-heeled shoes. It is integrated into the upper surface of the shoe body to accommodate an additional insole. The front and rear ends of the midsole surface have front and rear receiving grooves, respectively, for the separate insertion of the front and rear cushioning pads. Corresponding receiving grooves are formed on the front and rear ends of the insole bottom surface for the insertion of the corresponding front and rear cushioning pads. The thickness of the aforementioned front and rear cushioning pads is greater than the depth of each receiving groove, so that the cushioning pads of the midsole and the insole protrude towards each other and press against each other. Through geometric interference and space filling effect, the shear force generated during walking is effectively offset, preventing the insole from sliding horizontally relative to the midsole, thereby improving the stability and comfort of the foot when wearing the shoe.
