Abstract

Shoes made by fastening the layers of the upper on to a suitable former with their lower edges temporarily held in place while a sole is moulded directly against the underside of the former to become bonded to the edges of the layers of the upper. The uppers may be secured by stitches, pins, adhesives, suction, by magnetic attraction generated between the former and a coating on the inside of the upper materials, or by laces. The outer surfaces of the edges of the upper materials may be coated with something to promote adhesion with the injected sole materials or may be perforated to provide anchorages within the sole matrix. Pref. fastenings are used and disengaged in a manner concealed by the finished shoe. Claims shoes with foamed polyurethane soles. The use of a prefabricated inner sole fixed to the uppers is avoided.
