An installing hole forming mechanism includes at least one guiding sleeve and an inserting set. The at least one guiding sleeve includes a bore. The inserting set is detachably coupled to the at least one guiding sleeve and includes at least one spike configured to couple to the bore of the at least one guiding sleeve. The at least one spike includes a tip. When the at least one spike passes through the bore of the at least one guiding sleeve, the tip exposes from the guiding sleeve, and the at least one spike and the at least one guiding sleeve are forced to puncture a shoe such that at least one installing hole is formed on the shoe.

A boot-type orthopedic or sports footwear usable for controlled walking with stiffening for the lower extremities of legs, comprises: a sole provided with a substantially vertical rear positioning element; a first pair of rear half-hulls, each of which is hinged onto the sole and which cover, when in the closed position, an ankle and part of the lower portion of a leg, i.e. the calcaneal-tibial-tarsal zone, of an individual who is wearing the footwear; a second pair of front half-hulls, each of which is hinged onto the sole and which cover, when in the closed position, at least an upper part of a foot of the individual who is wearing the footwear.

The invention relates to a closure buckle for closing a ski boot, which buckle comprises a main lever (2) hinged to a base (1) and having a longitudinal notch (20) in which a tie rod (3) is mounted that is connected to a fastener hook and that has an end carrying an auxiliary lever (4), said buckle being characterized in that the main lever (2) is provided with a protective plate (21) laterally defining a housing (24) for receiving the auxiliary lever (4), and the invention also relates to a downhill ski boot equipped with such buckles.

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.

Sports boot comprising: an inner boot (3); an exogenous shell (1), the dimensions of which allow said inner boot (3) to be inserted into or extracted from it, said exogenous shell strengthening said inner boot and allowing it to be attached to a piece of sports equipment; wherein said exogenous shell comprises a sole (10), a forward part of an upper (11) able to pivot with respect to said sole (10) about a first articulation (110), and a rear part of an upper (12) which is able to pivot with respect to said sole (10) about a second articulation (120).

A ski boot includes a cuff and a lower shell mutually coupled to define a substantially rigid support structure, and a liner defined to receive the foot of a user positioned inside the rigid support structure. The support structure has first and second end portions mutually slidable between a first initial position and a second operative position so as to vary the configuration of the ski boot. The ski boot further includes a plurality of elements for the connection of the end portions, and a single lever that can be maneuvered by the user and is connected with the connection elements, so that the action of the lever allows the displacement of the first and the second end portions from the first to the second position. The single actuation lever can be selectively actuated by the user and is configured to act simultaneously on all connection elements.

A ski boot, including an outer boot (200) and an inner boot (100); the outer boot (100) comprise a sole (110) and a vamp (120), the sole (110) being integral; the vamp (120) includes a right side portion (122) of the vamp and a left side portion (123) of the vamp, the right side portion (122) of the vamp and the left side portion (123) of the vamp being hinged on the sole (110) such that the same may rotate relative to the sole (110) between an open state and a closed state; the outer boot (100) further includes a locking device (130) and a locking wire (140); the locking wire (140) surrounds the vamp (120) at a plurality of locations on the vamp (120), may be buried in the locking device (130) so as to keep the right side portion (122) of the vamp and the left side portion (123) of the vamp in the closed state, and may be released from the locking device (130) to allow the right side portion of the vamp (122) and the left side portion of the vamp (123) rotate to the open state. Therefore, the ski boot may facilitate a skier putting on and taking off the outer boot (100).

Sports boot including: an inner boot; an exogenous shell, the dimensions of which allow the inner boot to be inserted into or extracted from it, the exogenous shell strengthening the inner boot and allowing it to be attached to a piece of sports equipment. The exogenous shell includes a sole, a forward part of an upper able to pivot with respect to the sole about a first articulation, and a rear part of an upper which is able to pivot with respect to the sole about a second articulation. The sole includes a continuous inner relief pattern having longitudinally-extending ribs separated by longitudinally-extending grooves extending continuously along an entire length of the sole. The inner boot includes a sole with a corresponding relief pattern, so as to position laterally and vertically the inner boot in the exogenous shell.

A ski boot, including an outer boot (200) and an inner boot (100); the outer boot (100) comprise a sole (110) and a vamp (120), the sole (110) being integral; the vamp (120) includes a right side portion (122) of the vamp and a left side portion (123) of the vamp, the right side portion (122) of the vamp and the left side portion (123) of the vamp being hinged on the sole (110) such that the same may rotate relative to the sole (110) between an open state and a closed state; the outer boot (100) further includes a locking device (130) and a locking wire (140); the locking wire (140) surrounds the vamp (120) at a plurality of locations on the vamp (120), may be buried in the locking device (130) so as to keep the right side portion (122) of the vamp and the left side portion (123) of the vamp in the closed state, and may be released from the locking device (130) to allow the right side portion of the vamp (122) and the left side portion of the vamp (123) rotate to the open state. Therefore, the ski boot may facilitate a skier putting on and taking off the outer boot (100).
