Abstract
Abstract A ski binding adapted to release under predetermined conditions, and wherein the binding will release in a forward fall, or a twisting fall or any combination of the forward fall or twisting fall. The ski binding releases by rotation on or near the ball of the foot, and wherein the contact points of the heel and toe may be on rollers or hinges to reduce friction, and wherein there is provided a turntable for the ski boot. The binding is so constructed that in a forward twisting fall, the heel will release before any pressure is applied between the sole of the boot and the ski at the toe thereof.
