said grid of resilient sections comprising substantially all of said inner sole and extending over substantially all of said sole area;
wherein said resilient sections have a height, a width and a depth, said height being substantially equal to or greater than said width and depth;
each said section being independently removable from said footgear;
said sections being less than ¾
inch in transverse extent;
said elements or sections being moldable to retain the configuration of the patient'"'"'s foot, with the heights of the sections being deformed to retain different heights in accordance with the pressure applied to the sections of the insole by the patient'"'"'s foot; and
said sections as defined above including means for permitting swaying of each section involving swaying movement of the upper surface of each section, with the lower surface of each section remaining fixed;
whereby the resilience of the sections at normal ambient temperatures below 200°

Abstract
An orthopaedic shoe has an outsole and a special insole including an array of independently vertically movable sections or elements which are heat moldable to retain the contour of the users foot and which serve to reduce or avoid peak pressures and evenly distribute pressure during walking. The resilient sections preferably have a height which is substantially equal to or greater than the lateral extent of the sections, to permit swaying action and to reduce shear forces on the users feet.
