Abstract
A prosthetic liner includes a convex exterior surface, a concave interior surface and a rim portion connecting the interior surface and the exterior surface. The liner includes a plurality of recesses and a plurality of fingers. Each of the plurality of recesses is formed in the exterior surface of the liner without extending to the interior surface of the liner. The plurality of fingers is positioned in the plurality of recesses and each of the plurality of fingers is connected to the exterior surface and extends toward the rim portion. The plurality of fingers may be resiliently moveable in the plurality of recesses. The plurality of fingers may be integral with the exterior surface of the liner. The rim portion may define a plane into which at least one of the plurality of fingers extends.
