Abstract This is a method for coating or adhesively bonding surface, particularly for bonding tread members to shoe uppers, in which urethane polymeric material containing reactive -NCO groups and having crystalline segments in the polymer molecule is applied in fluid condition for wetting engagement with a surface and is converted through reaction to tough solid but still heat softenable condition. The coated surface in heat softened condition may be pressed against a surface to which it is to be bonded to form an adhesive joint, and the joint cooled to give a strong adhesive union between the surfaces.
