Abstract
Abstract Rolling skating shoe with injection molded sole in which receptacles are provided that support the wheel hangers and wheels. The sole shown has a structural beam "T" profile, the flange of which supports the foot and the lower rib of which has an irregular lower edge forming a series of apertured angled bosses to receive the wheel hanger structure. Receptacles in the form of embedded threaded connectors enable bolting of the wheel hangers directly to the injected sole. The method for forming this shoe includes placing the threaded connectors into the mold and then injection molding the sole of semi-rigid plastic directly against a string lasted upper held in place by a last.
