Abstract: A waterproof shoe includes an upper having a bottom open end which has an outer surface and an inner surface, an outer welt extending along the outer surface of the bottom open end, and an inner welt extending along the inner surface. The bottom open end is sewn to the outer and inner welts, thus forming a stitch seam. An outsole has a top side connected integrally to the bottom open end and the outer and inner welts, a bottom side, and a peripheral face connected between the top and bottom sides. The top side penetrates through the stitch seam and clearances present between the bottom open end and the outer and inner welts. The outsole is produced by forming a molding material immediately below the upper and by causing the molding material to flow into the clearances during the forming of the molding material.
