The invention also covers the footwear assembly equipped with this device.

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.

The present invention contemplates a binding system for a snowboards and the like. The system includes a soft-soled boot having a hardened exterior shell consisting of a toe portion and a heel portion, which are linked by at least one sidewall portion. The toe and heel portions include two toe and two heel pegs respectively. The boot includes an instep portion having instep cables for adjusting the boot to the wearer and the cables are adjusted by grommets and tightened in position by at least one resting bar. The binding has a base plate for connecting to the snowboard. The base plate further supports a pair of toe hooks adapted to engage the toe pegs and a pair of heel peg levers adapted to releasably engage the heel pegs of the boot. A grappling hook and ratchet mechanism grabs the resting bar on the boot.

A front insert for a ski mountaineering boot has first and second heads, positionable on lateral portions of a front part of the boot, a first housing in the first head, a second housing in the second head, and two contact elements with respective holes for coupling with respective hooking elements of a binding. The housings and respective ones of the contact elements are reciprocally conformed so as to enable the contact elements to displace from internal positions with respect to the housings, towards the outside, so that the contact elements orient with respect to the housings so that the holes can misalign from an alignment axis to maintain the contact with the hooking elements following a rotation of the ski boot with respect to the ski.

Ski boot device for ski boots (1). Ski boots have a front sole section (3) with a front interaction surface associated with binding and releasing from a front ski binding, and a rear sole section (4), in a common plane (8), with a rear interaction surface associated with binding and releasing from a rear ski binding. The ski boot device of the present invention is attached to the ski boot and comprises a toe portion formed and attached to the ski boot sole (3) without interfering with the front interaction surface during binding or releasing, a heel portion formed and attached to the heel (4) of the ski boot without interfering with the rear interaction surface during binding or releasing; and a support portion (10A, 10B) provided intermediate the toe portion and heel portion and having a shaped profile which extends below the common plane and provides a contact surface during walking.

Sport footwear for practicing winter sports comprising a shell (11) made of a first thermoplastic material and comprising a toe coupling projection (12) at the front and a heel coupling projection (13) at the back, configured to couple releasably to the bindings of a ski or snowboard. The sport footwear comprises at least a coupling projection protection cover (15, 16) releasably attached on at least one of, or both, said toe coupling projection (12) and heel coupling projection (13), and said at least one coupling projection protection cover (15,16) is made of a second thermoplastic material.

The present invention relates to an attachment mechanism for a shoe, the attachment mechanism comprising at least two pins (1), one on each side of the shoe, where the pins (1) are arranged in their respective guides (3), the pins (1) being designed to cooperate with a complementary retaining means (12). The attachment mechanism is, inter alia, characterised in that the attachment mechanism further comprises forcing means that are designed to force the pins (1) outwards into engagement with the complementary retaining means (12), and inwards out of engagement with the complementary retaining means (12).

The invention relates to an automatic heel unit (1) for a ski binding, comprising a base (7) for fitting the automatic heel unit (1) on a ski and a heel downholder (3) for holding down a ski boot in a heel region of the ski boot. The heel downholder (3) is mounted so as to be movable in relation to the base (7). The automatic heel unit (1) has a holding configuration in which the heel downholder (3) is located in a holding position and may interact with the heel region of the ski boot that is held in the ski binding in such a manner that the heel region of the ski boot is held down in a lowered position. Furthermore, the automatic heel unit (1) has a step-in configuration in which the heel downholder (3) is located in a step-in position and the heel region of the ski boot is released by the heel downholder (3). The automatic heel unit (1) comprises a heel support structure (6), which is configured separately from the heel downholder (3), for supporting, in a direction that is horizontally transverse to the ski, the heel region of the ski boot that is held in the ski binding in the holding configuration of the automatic heel unit (1).
