ABSTRACT:
A ski with a non-rectangular cross section has a filling core, for example made of polyurethane foam, a shell forming the upper face and at least a part of the lateral faces of the ski, a lower face equipped with longitudinal metal edges and with a central sliding sole. The ski includes two longitudinal reinforcement elements which extend at least in the binding mounting area of the ski and are arranged on either side of the core, each reinforcement element has a lower face which extends to a great extent over the width of an edge so as to afford it an effective support, and extends over at least a part of the height of the ski, the reinforcement elements not being covered laterally by the shell and thus forming the narrow sides of the ski, at least in the binding mounting area of the ski.
