Claim:
A method for manufacturing casual shoes comprising the steps of: preparing an upper and an outsole, the upper having an upper portion conforming to the shape of a foot, a lower portion and an upper seal portion formed at its lower portion with the outsole having a lower bottom portion and an outsole seal portion extending a predetermined height above the lower bottom portion such that said outsole seal portion forms an upstanding self supporting peripheral rim; applying an adhesive agent to an outer surface of the upper seal portion formed at the lower portion of the upper and to an inner surface of the upstanding self supporting peripheral rim of the outsole seal portion; inserting the lower portion of the upper into the outsole seal portion of the outsole such that said upper seal portion faces and overlaps the upstanding self supporting peripheral rim of the outsole seal portion without any folding over of the lower portion of the upper on the lower bottom portion of said outsole; stitching the upper seal portion of the upper to the upstanding self supporting peripheral rim of said outsole along said overlap with said applied adhesive disposed therebetween so as to seal the outsole to the upper without incorporating an insole in the sealing operation; mounting a conventional insole upon the lower bottom portion of the outsole for structural support and comfort; activating the adhesive agent by applying heat to the stitched seal portion; and molding the upper and the outsole using a compression molding machine.
