Abstract: A boot for a ski or an in-line roller skate has a flexible upper and a sole allowing the foot to flex during walking. Its sole has a rigid part in the rear region of the boot, over about one half of the length of the sole, this rigid part being designed so as to form an interface between the heel and a binding of the ski or in-line roller skate. The interface may be standard, that is to say independent of the boot size.

Abstract: A board for gliding for downhill skiing, of “shell” type construction having, at lest in an underfoot zone a lower gliding surface composed of a sole plate bordered by metal edges and a topsheet substantially parallel to the lower gliding surface, on either side of the center longitudinal plane of the board. The underfoot zone further includes lateral faces extending between the metal edges and the topsheet, the lateral faces having recesses located below the plane of the topsheet and opening out in the latter.

Abstract: A gliding board has a raised platform which is intended to accommodate the toe piece and the heel piece of a safety binding on its upper part and which rests on the board via its central part. The platform has its front and rear ends overhanging relative to the upper surface of the board and not resting on the board. The platform has a torsional stiffness such that the maximum angular deformation of a free end under the effect of a twisting moment of four newton-meters exerted at four hundred and sixty millimeters from an engagement zone is less than one and a half degrees.
