ABSTRACT:
An apparatus for shifting the body weight of a skier from a skier's legs to the skis for enhancing the skier's performance and minimizing leg strain comprises a spring assembly including a loop of elastic rod-shaped material stretchable during crouching movement of a skier's legs between a standing position and a fully crouched position of the skier. A housing defining an elongated channel for enclosing a portion of the loop supports the stretchable material and parallel rod-shaped branches terminating in a base bend. The base bend is secured within one end of the housing. The housing also includes a socket for receiving rigid poles therein and supporting the poles in vertical positions above the skis. The top ends of the poles have pulleys therein over which a cord is fed extending from a top bend of the loop or elastic material to straps disposed about the thigh or thighs of the skier's legs. The housing is secured to the back of the boots of the skier so that the skier's weight transferred to the rigid poles is in turn transferred to the skis.
