Prosthetic liner formed of a molded silicone elastomer material including an inner wall, a circular outer wall having radii of curvature centered along a first longitudinal axis of external symmetry extending longitudinally centrally within the liner, the inner wall including a circular curved inside anterior wall portion extending along a liner length and having first radii of curvature centered on a second longitudinal axis of anterior curvature extending longitudinally along the liner length and a circular curved inside posterior wall portion having a second radii of curvature centered on a third longitudinal axis of posterior curvature extending along said liner length. The first, second and third longitudinal axes lie in a common longitudinally and transversely extending plane bisecting the anterior and posterior wall portions, and the second and third axes are spaced apart a predetermined offset distance on opposed sides of the first axis to thereby define an anterior wall portion that is thicker along the liner length than the posterior portion.
