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 ski boot (1) includes a base frame (2) for receiving a foot of a skier; a rigid sole (3) connected to the base frame (2); a shaft (4) for receiving a lower leg part of the skier, the shaft (4) being angularly variably connected to the base frame (2); and a traction element (12). The traction element is attached to the sole (3) and/or in a toe area of the base frame (2) and extends from there to a heel area of the sole (3). In the heel area, the traction element (12) is deflected towards the shaft (4) and is then attached to the shaft (4). By inclining the shaft (4) towards a toe region, the traction element (12) can be tensioned and, in particular, traction can be exerted on the sole (3) and/or the toe region.

A ski boot, comprising a ski boot shell and a ski boot sole, wherein the ski boot sole comprises a front end of the ski boot sole, a rear end of the ski boot sole, a lower side of the sole and a free upper side of the sole via which the ski boot sole protrudes forwards, backwards and/or laterally beyond the ski boot shell, wherein the lower side of the sole comprises a first bearing region for placing upright on a bearing plate of a ski binding, and a second bearing region for walking without skis, wherein a width of the ski boot sole in the second bearing region is larger than a width of the ski boot sole in the first bearing region.

A locking device for sports footwear is adapted to lock two mutually hinged portions of sports footwear or to release them from each other. The locking device may be used in a ski boot for locking or releasing the shell and cuff relative to each other. The locking device comprises a male member and a female member, which members comprise respective engaging elements adapted to cooperate with each other, and actuating elements for moving the members from a configuration in which the male member is disengaged from the female member to a configuration in which the male member is engaged with the female member. The engaging elements of the male member and/or the engaging elements of the female member have a tapered or conical shape, whereby it is possible to make a coupling without clearance between the male member and the female member when the members are engaged.

A 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 be able to couple to a ski binding device; a rigid cuff which is shaped so as to enclose the lower part of the leg of the user, and is pivotally joined to the shell so as to be able to swing about a rotation axis substantially perpendicular to the midplane of the boot; and a cuff locking device which is located on the cuff and is selectively adapted to rigidly connect the cuff to the shell to prevent the cuff from swinging on the shell; the cuff locking device, in turn, comprising a movable arm which is pivotally joined to the cuff so as to be able to rotate to and from a locking position in which the movable arm extends downwards and arranges its distal end in abutment on an anchorage structure present on said shell, and an elastic assembly which is adapted to bring and elastically retain the movable arm in the locking position, and which basically consists of a telescopic stem that lies substantially on the rotation plane of the movable arm and is interposed between the movable arm and a fixed point on the cuff, and of an elastic opposing member that is fitted on the telescopic stem, and acts on the telescopic stem so as to bring and elastically maintain the telescopic stem in a maximum extension configuration.

A ski boot, comprising: a rigid ski boot shell; and a sole of the ski boot which comprises a free upper side, which protrudes forwards in the longitudinal direction of the boot and/or laterally beyond the ski boot shell, and a lower side, wherein the ski boot comprises a front attaching region which co-operates with a front part of a ski binding in order to secure the ski boot, and a front region of the ski boot stands upright on a planar base via the front attaching region, wherein the upper side of the sole exhibits a distance, orthogonally with respect to the base, of at least 25 mm at a front end of the sole of the ski boot, and the upper side of the sole has a distance from the lower side of the sole, measured perpendicular to the base, of 19 mm2 mm at a distance from the front end of the sole, measured in the longitudinal direction, of at least 28 mm, and wherein, with the ski boot standing upright on the base, the lower side of the sole has a distance from the base of at least 5 mm throughout, up to a distance of 40 mm10 mm from the front end of the sole, as measured in the longitudinal direction.
