1. A prosthetic liner adapted to provide an interface between a residual limb and a prosthetic socket, the prosthetic liner comprising:
a body portion having an elongate and generally conical shape and formed from an elastomeric material, the body portion defining an inner surface, an outer surface forming a liner profile between a closed distal end and an open proximal end, and an axis extending between the distal end and the proximal end;
wherein the body portion includes a seal element region having at least one seal element formed by the prosthetic liner and the elastomeric material of the body portion, said at least one seal element variably protruding radially outward relative to the axis about a circumference of the body portion such that the at least one seal element at least defines a first seal height and a second seal height at first and second circumferential positions, respectively, about the circumference of the body portion;
wherein the first and second seal heights are defined by a distance between the outer surface of the liner profile adjacent to the first and second seal heights and a radially outward end of the at least one seal element measured normal to the liner profile, the first seal height being different from the second seal height.
