ABSTRACT:
A temperature-proof shoe formed by adhering a hollowed shape forming guide plate, which is circumferentially larger than an insole board that is the same size as the bottom surface of a form block, to the underside of a closed cell polyurethane foam layer at the sole portion of a shoe, and tucking in a leather facing in a manner to wrap up the forming guide plate with it. Also, by a roll-in outstitching applied to the leather facing and the outer circumference of the forming guide plate protruding to the outside from the leather facing of the instep portion, the temperature-proof shoes are free from the intrusion of water, satisfactory in heat-retaining property and excellent in design.
