Abstract
Abstract A snow ski training device comprising a pair of straps, one connected to each of a skier's legs just above the knee, and a releasable connection therebetween. The device provides a sensation, such as a popping noise, when the skier's knees are moved apart. The connection may take the form of a ball connected to or integral with one strap, and a cooperating socket connected to or integral with the other strap. The connection members may be made of silicone rubber to retain desired resilient properties even in very cold weather.
