Abstract
A motorcycle boot includes a lower vamp shell having a front tongue and rear tapering flaps which extend into an upper shell assembly formed by a hinged front door and a rear cuff. The door, of impact resistant plastic to protect the wearer's shin, interleaves with the cuff and is closed by overlying flexible straps. A closure system includes wire bales, longitudinally adjustable within holes spaced along the straps, and received with toothed latched receivers. The side legs of each wire bale snap-fits under locking flanges when the bale is closed over center. A connector hinge assembly includes a slotted plate, attached to the vamp shell, through which extends a freely movable pivot pin journalled in the upper shell to allow forward and rearward motion, rockable sideways motion, and lateral twisting of the shells. A replaceable sole insert, formed by a resilient pad molded to a carrier plate, is mechanically locked within a base recess on the bottom of the shell. An inner liner extends through the upper shell and is sealed to the lower vamp. A replaceable bootie extends into the vamp shell and is fastened to the inner liner.
