Abstract

The shoe bottom (FIG. 2) is made of a thermoplastic material and is profiled, in such a way that the upper surface thereof A shows, at its rear part, a depression A1 for the heel of the foot, that connects with the front of the shoe bottom by means of the curved lengths A2 and A3, to terminate with an ample area A4 for the sole of the foot. The lower surface B of the shoe bottom is correspondingly shaped and shows, at the rear part thereof, a flat notch B1 for the heel of the shoe and successively, an arch-shaped profile B.sub.2 and B.sub.3, the radiuses of curvature of which increase from the heel toward the sole. As a consequence, the thickness of the shoe bottom decreases gradually from the heel toward the toe. The lower surface of the shoe bottom shows, in front, a notch B.sub.4 to house an element resistant to wear, made of leather or of another appropriate material.
