Abstract
Abstract A hinged sport boot having an upper boot portion with hinge openings in its sides and a lower boot portion with integral, headed, hinge pins projecting from its sides. The heads of hinge pins are slightly larger in size than the openings so that the pins must be forced through the openings to hingedly connect the upper and lower portions together. A locating depression is provided on the central outer surface of the head of each pin to properly locate a connecting tool used to connect the boot portions together. The invention is also directed toward a method for connecting the boot portions together.
