Abstract: A device for retaining a boot on a sports apparatus. The device includes a covering portion, which itself includes a longitudinal reinforcement and a shock-absorbing pad. The hardness of the shock absorbing-pad increases from an inner end toward an outer end of the reinforcement.

Abstract: Ski shaped like an elongated beam, comprising a lower slide face bounded laterally by two lower edges, an upper face bounded laterally by two upper edges, and two lateral faces, the ski being constituted by a central part extended toward the front by a front part ending, at its front end, by the tip and extended toward the rear by a rear part ending, at its rear end, in the heel-piece. The front part is constituted by a front section connected to the central part by a front intermediate connection section, while this rear part is formed by a rear section connected to the central part by a rear intermediate connection section. The two upper edges of the upper surface are parallel in the central part, while one of the two front or rear section is such that, in this area, first, the lateral faces are inclined so as to converge upward, and second, the upper surface is narrower than it is in the central part and has a uniform width.
