A method of assembling a boot is provided. The method comprises forming a first layer of insulation material of the boot covering a toe region, a saddle region, and a heel region of the boot; forming a second layer of insulation material of the boot that covers the saddle region and the toe region and does not cover the heel region of the boot; forming a third layer of insulation material that covers the toe region and does not cover the heel region and the saddle region of the boot; and attaching the first, the second, and the third layers of insulation material to an outsole of the boot.

A one-piece rubber boot shell is created by a process comprising the steps of disposing rubber pieces within a cavity of a molding machine, the molding machine having an upper mold, a lower mold, and a last suspended between the upper mold and the lower mold. The process includes closing the molding machine by moving at least one of the upper mold, the lower mold, and the last toward each other so that they are adjacent each other, heating the rubber pieces to flow within the cavity and around the last to form a one-piece rubber boot shell, and opening the molding machine by moving at least one of the upper mold, the lower mold, and the last away from each other so that they are spaced apart from each. The one-piece rubber boot shell is then removed from the last.

A heel protector (100) includes a leg engaging section (101) and a foot engaging section (102) intersecting at a heel receiver (103). The leg engaging section (101) and the foot engaging section (102) define a leg insertion aperture (104). The leg engaging section (101) defines at least one aperture (203) disposed in an ankle region (205) to permit a connection tube (1002) extending from an inflatable bladder (901) of a compression device (800) to pass therethrough. The heel protector (100) and compression device (800) work together as a rehabilitation system (1300).

A shoe comprises a sole having an upper surface and a lower surface, and a top member having an outer surface and an inner surface and mounted on the sole. The top member and sole to together define a space for receiving a foot, and the top member further comprises an opening. A fastener is provided in the top member and extends from the opening and continues over the top member such that a portion of the top member is movable between a first position in which the space is substantially closed and a second position in which a portion of the top member is folded back from the sole to provide access to the space, and further comprising areas with controllable expansion to accommodate an ankle or foot brace.
