ABSTRACT:
A ski having a lower sliding surface and a pair of opposite lower edge portions; an upper surface; a central zone, a front contact zone and a rear contact zone; a pair of lateral surfaces on opposed sides of the ski, each of the pair of lateral surfaces extending between the upper surface and a respective one of the pair of opposite lower edge portions of the lower sliding surface; at least one of the pair of lateral surfaces being disposed, with respect to the lower sliding surface, to form an angle, in transverse cross-section, between a line representative of the at least one of the pair of lateral surfaces and a line extending between the pair of opposite lower edge portions, the angle decreasing continuously between said central zone and at least one of the front contact zone and the rear contact zone. The body of the ski can include a core which extends substantially the length of the body and a casing substantially surrounding the core for establishing the mechanical resistance properties of the ski. The outer profile of the ski, or the outer profile of the casing, is constructed and arranged such that the mechanical resistance properties of the ski at each location along the length of the ski is a function of such location.
