Abstract: A pair of skis suitable for both slalom and giant slalom ski racing. This is achieved by providing a pair of skis so that corresponding inside edges have the same sidecut. Each of the outside edges of the skis may have the same sidecut as the other, but different from the sidecut of the inside edges. When the skis are reversed, the outside edges become the inside edges, and the inside edges become the outside edges, either changing the skis' suitability from giant slalom or slalom, or from slalom to giant slalom. Stiffening plates can be attached to the skis to provide rigidity and stability required by the skis for giant slalom racing and removed for slalom racing.
