ABSTRACT:
A heel support for supporting an person's extremity includes an inflatable air bag having three panels, a middle panel and two side panels. An upper surface of the middle panel has a smaller radius of curvature than upper surfaces of the side panels. The panels are connected together in a manner which allows the two side panels to collapse inwardly toward the bottom panel. The side panels fold inwardly toward one another and are secured by an attachment means, preferably hook-and-loop strips.
