A ski boot of the kind comprising a substantially rigid outer shell and a cuff articulated to the shell is provided and further includes a locking device which can be switched between a first configuration, in which the rotation of the cuff relative to the shell is allowed, and a second configuration, in which the rotation of the cuff relative to the shell is prevented. The locking device of the ski boot also includes deadlocking means which prevents the locking device from being accidentally moved from the configuration in which it is, specifically when it is in the second configuration.

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.

An example sport boot includes at least one terminator provided in a cavity formed in a base of the sport boot. A first cable having a first end terminating in a first receptacle of the at least one terminator extends out of a first side of the base of the sport boot, around a foot portion of the sport boot and into a second side of the base of the sport boot. A second end of the first cable terminates in a second receptacle of the at least one terminator. A second cable having a first end terminating in a third receptacle of the at least one terminator extends out of a rear side of the base of the sport boot and is attached to a handle mounted on the rear (cuff) portion of the sport boot.
