Ski boot comprising a rigid shell which is shaped so as to accommodate the foot of the user, and has a lower part structured to couple with a ski binding device; a rigid cuff which is shaped so as to surround the lower part of the leg of the user, and is pivotally jointed to the shell thus to be able to pivot about a rotation axis substantially perpendicular to the midplane of the boot, and shell closing means adapted to selectively tighten the shell on the foot of the user; the shell comprising a substantially basin-shaped casing which is superiorly provided with a main opening from which the leg of the user comes out, and with a longitudinal slit that branches from said main opening and extends along the casing towards the front tip of the shell; the shell closing means being placed at the longitudinal fissure.

A buckle includes a base and a grip lug. The base underside can be placed against and fastened to a boot shell. The base upper side has at least one first receiving extension. In an engagement position a swivel element on the lug is latched at least in certain regions in the first receiving extension to form a swivelable first latching connection, to permit swiveling the lug in the engagement position from an open into a closed engagement position by the swivel element. At least one first latching extension is on the base upper side, and the lug has at least one latching element corresponding thereto. In the closed position, the latching element is latched at least in certain regions on the first latching extension to form a releasable second latching connection, to secure the lug against leaving the engagement position and against swiveling into the open position.

Ski boot comprising: substantially rigid foot-casing, which is adapted to accommodate the foot of the user; a substantially rigid cuff, which is adapted to surround the lower part of the leg of the user, and is hinged on the foot-casing so as to be able to swing about a transversal rotation axis, which is substantially perpendicular to the boot midplane; an oblong-shaped tongue, which is arranged longitudinally to close the upper part of the foot-casing; and a foot-casing closing assembly, which is adapted to close/tighten the upper part of the foot-casing on the foot of the user and comprises: a first fairlead member, which is located on the hinge that connects the cuff to the foot-casing; a plurality of second fairlead members, which are arranged along a first major longitudinal edge of the tongue, in part integral with the foot-casing and in part integral with the tongue; and a cable winding winch, which is located on the cuff or on the tongue and is provided with a flexible cable, which comes out from the cable winding winch itself, engages in freely slidable manner and in succession said first and said second fairlead members, and has the distal end fastened to the tongue or to the foot-casing.
