Abstract
A method of making a shoe comprises sewing a rear stitching margin of a rear section of an upper to a midsole, gluing and attaching a rear section of an outsole to the midsole and the rear stitching margin, and stitching a front stitching margin of a front section of the upper directly to a front section of the outsole. The method is simple since it dispenses with use of a heel lasting machine which requires complicated processing steps. The method provides a shoe with good flexibility at a front section of the shoe and sufficient support at a rear section of the shoe.
