Abstract: A ski boot consisting essentially of a comfort liner (8), a lower shell (1) and a cuff (2) articulated to the lower shell. The cuff is provided with a strap (62) in its upper part and a lower-leg band (61) made of a material which is more rigid than the material of the cuff, these being rigidly connected to one another on the side of the boot corresponding to the inside of the foot.

Abstract: Buckle, comprising a tensioning lever (4) which is articulated onto a base (1) and has a longitudinal notch (6) in which a link rod (7), connected to a fastening member (10), is articulated. The notch (6) and the link rod (7) are laterally offset relative to the longitudinal mid-axis of the tensioning lever toward the side of the buckle which is intended to be arranged toward the rear of the boot, while the other side of the tensioning lever has a decreasing height forming a ramp (16, 16a) over which the slalom poles which the boot encounters can slide without risk of catching or opening the buckle.

Abstract: The boot, made of plastic material, comprises a shell of variable volume (1) having two longitudinal flaps (2, 3) which overlap on at least one part of the foot, and a shaft in the form of a collar (7) articulated on the shell. Only the flap (3) of the internal side of the boot extends at the same time over and at least in part above the instep. The missing part of the other flap (2) is replaced by an auxiliary piece (6) which is integral with a covering piece (5) which envelops the metatarso-phalangeal zone. Putting the boot on is facilitated by this, while a good transmission of the forces from the leg on the internal side of the boot for the edge grip is ensured.
