A boot especially adapted to sports that require movement of the foot, or to gliding sports, including an upper provided with a rear stiffener surrounding the heel and an external sole. According to the invention, the stiffener is rigid and substantially non-flexible, and extends along at least one side of the boot, up to the so-called metatarsophalangeal bending zone. According to a second aspect of the invention, the stiffener is rigid and substantially non-flexible, and surrounds the heel and essentially the rear portion of the base of the foot, in the manner of a shell. This construction also allows for a better transmission of the forces, while maintaining a flexibility of the boot in the metatarsophalangeal zone, due to the reinforcement of the rear portion of the boot. These constructions permit a better control of the ski through the heel retention and, at the same time, a general gain of energy by eliminating the parasitic deformations of the sole and of the boot.
