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.

A ski boot for anchoring to a ski via a ski binding system includes a rigid foot enclosure including a bottom wall having a first mating surface. The ski boot also includes a sole block configured to selectively couple to the rigid foot enclosure. The sole block includes a second mating surface configured to mate with the first mating surface, the second mating surface defining a mating surface plane. The sole block also includes a traction surface configured to engage a ground surface, the traction surface defining a traction surface plane. The sole block is configured to support an insert fitting, the insert fitting defining at least one of a) a pair of opposed sockets or b) a pair of arcuate cut-away portions. A non-zero cant angle is defined between the mating surface plane and the traction surface plane.

A ski boot with removable and interchangeable soles. In one embodiment, the ski boot has a hull with a shaped plate, a sole adapted to be removed from the hull with the sole having a front portion and a back portion that are separated from each other and constrained to the hull via fixing screws. The removable and interchangeable soles allows the ski boot to be configured for specific skiing disciplines and is compatible with ski bindings provided with a plurality of pins integral with the ski that are fitted into corresponding shaped recesses of the hull. The shaped recesses are positioned on the sides of the plate, which is fixedly constrained to the ski boot.

Sports boot having a lower portion to surround a user's foot, an upper portion to surround the user's lower leg and movable in relation to the lower portion, and mechanisms blocking the lower portion in relation to the upper portion. The upper portion includes disjointed lateral and medial portions, each rotationally articulated with the lower portion. The blocking mechanisms include an element movable in relation to the lower portion between a blocking position, in which the blocking mechanisms at least partially lock upper portion movement in relation to the lower portion, and an unblocking position in which the blocking mechanisms allow upper portion free movement in relation to the lower portion. When the blocking element is in the unblocking position, the blocking mechanisms allow translational movement of the lateral portion in relation to the medial portion at least along a direction perpendicular to an outsole of the boot.

This invention relates to sports footwear, in particular a ski or snowboard shoe or boot, including a shell provided at the top with a longitudinal opening, a flap or tongue extending longitudinally along the shell and connectable near the region of the tip. The flap or tongue is capable of covering the opening and is removably connectable to the shell to define a first configuration of the sports footwear, in which the flap or tongue is connected to the shell in order to limit or prevent, during use, the oscillation movement of the user's leg in relation to the foot, and a second configuration, in which the flap or tongue is removed from the shell to allow, during use, the free oscillation movement of the user's leg in relation to the foot.

A shell for a ski boot of the kind comprising an outer shell made of a substantially rigid material and an inner liner made of a substantially soft material is provided. The shell is provided with a gaiter made of a waterproof material, and the lower edge of the gaiter is secured to the inner surface of the shell and the gaiter extends beyond the upper edge of the shell. Preferably, the base of the shell comprises a removable portion so that a through-opening is obtained in the base of the shell, which through-opening guarantees an easy access to the inner space of the shell for accurate securing of the gaiter to the inner surface of the shell.

A boot form for a hockey skate is made of multiple plastic materials having different hardness properties, or different flexural moduli, and is formed via an injection-molding process or another similar process. One or more of the plastic materials may be reinforced with fibers of glass, carbon, aramid, or another stiffening material to strengthen one or more regions of the boot form. For example, pellets of a first plastic material having a flexural modulus of approximately 190 MPa (e.g., a polyamide elastomer block amide) may be injected into a mold to form a softer upper region of the boot form. And pellets of a second plastic having a flexural modulus of approximately 20,000 MPa (e.g., a Nylon 12 with long glass fibers) may be injected into the mold to form a stiffer lower region of the boot form. Additional skate components may then be attached to the boot form.

Sports boot element of which the wall includes at least two different plastics materials (15, 16), the wall having (i) a first zone (11) including the two different plastics materials within its thickness, the first plastics material (15) forming two layers of the wall constituting the internal and external faces of the said wall, and the second plastics material (16) being interposed between the two layers of the first plastics material (15), and (ii) a second zone (13) including only the second plastics material (16).
