Abstract
A ski comprising an upper protective plate, a lower low-friction sole plate and a core of a synthetic-resin material molded between the plates and reinforced with steel filaments or wires extending the full length of the ski. Except at the spoon or toe of the ski and at the heel thereof, the steel filaments are bonded directly (without give or play) to the synthetic-resin core while at the heel and toe portions of the ski the steel filaments are bonded to the synthetic-resin core by an elastic pliable material (i.e. with give or play).
