A prosthetic ski leg designed to be attached to a stump of a wearer which has a pair of conventionally shaped binding mounts for stepping into ski bindings. The prosthetic ski leg includes several structural members having resilient properties for storing and releasing energy. The ankle portion functions as a primary bending load member and may be formed to control the inherent stiffness. A secondary stiffness member may be provided to contribute a level of stiffness or to limit the range of motion. An air bag having a pressure adjustment may be disposed between the secondary stiffness member and the ankle portion to increase or decrease the amount of contribution of the secondary stiffness member. A shock cord may also be provided to adjust the stiffness of the ski leg by varying the elasticity and length of the shock cord.
