ABSTRACT:
A semi-flexible molded polyurethane boot closed at the rear and sides and open at the front surrounds a breathable open pore foam inner liner which covers the lower leg, ankle and foot and which forms a principal element of an improved immobilization brace. The boot is fixed to a walking sole having a minimal rocker effect, and is of minimal thickness. A boot portion of the boot has a rounded heel counter and a contoured footbed. A shock absorbing foam insole within a boot portion recess pads the plantar surface of the sole. The dorsum of the boot and the boot upper are provided with ventilation ports to ventilate the leg, ankle and foot of the user through the porous open foam liner. The dorsum of the boot portion of the boot and the boot upper are provided with spaced adjustable, leverage type closures to provide adjustable general compression and focal compression to assure a proper fit of the brace and to reduce edema induced swelling throughout the leg, ankle and foot. The boot upper and boot portion may be formed of two parts hinged together, but locked to prevent fore and aft rotation of the boot upper relative to the boot portion fixed to the sole.
