ABSTRACT:
A ski boot upper is accurately produced by injection molding to form thereon a pair of trunnion elements properly positioned relative to the malleoli of the human anatomy. A leg component of the ski boot made conventionally has openings which pivotally receive neck portions of the trunnion elements, whereby proper articulation of the leg and upper are assured to enhance the comfort, convenience and mobility of the wearer.
