said pad having a base layer;
said pad having a plurality of molded substantially hollow structures to provide differing levels of cushioning support for the wearer of the orthopaedic support at different areas of the pad, at least some of said structures having a different dimension than others of said structures; and
said hollow structures extending substantially perpendicular from said base layer;
said hollow structures being integrally molded with said base layer;
wherein said molded structures comprise walls, said walls providing cushioning support for the ankle and having a self supporting free standing construction even without inflating or otherwise filling said molded structures with air, liquid, or gel.

Abstract
An ankle support (100) is constructed using a molded pad (110) and a rigid shell (112). The pad (110) and the shell (112) may be sealed together to form a bladder-pad cushion for comfort. The internal structure of the pad (110) is molded to include geometrically shaped cells of various size, shape and thickness to provide differing levels of localized comfort to the user of the ankle support (100). The pad may be made from a thermoplastic elastomer (TPE) which is spring-like and resists compression sets. The pad may include integrally-molded fingers extending to the shell. The fingers may have different lengths in one or more regions, in order to increase the cushioning effect in a particular region. The pad/shell combination may form a sealed bladder, and a pneumatic pump may be provided in conjunction with the shell so that the user can inflate the bladder.
