ABSTRACT:
A ski has at least two downwardly-extending projections (10, 16, 16B), at least one on each side of the longitudinal axis of the ski, these being integral with the remainder of the ski separate members, in the form of an inverted channel member (7), the base (7A) of the channel, on the upper side of the channel member (7), lying above and being secured to the tail (1) of the ski, which extends between the side walls (7B) of the channel member (7). When the ski is placed on a flat horizontal surface, with the running face (3) of the ski lowermost, the tips (10A, 16A) of the projections (10, 16, 16B), at the lowermost extremities of the projections, will be separated only by an air gap from the surface.
