ABSTRACT:
A ski or ski-like device with an improved edging feature to assist skiers in edging during icy conditions. The edging feature includes a structure and method that provides a lateral edge on the inside of the ski that can extend into the snow surface beneath the bottom surface of the ski. When the ski is turned (i.e., rotated about its longitudinal axis) the extended inside edge of the downhill ski digs into the snow surface to provide improved gripping and control. The edge adapted to extend beneath the bottom surface of the ski is provided either by attaching an edge that extends below the bottom surface of the ski, or by providing a bottom surface of the ski in the region adjacent to the extended edge that is arranged to yield under pressure, to expose the extended edge when vertical force is applied to the bottom surface of the ski during a turn.
