The present invention relates to a thermoplastic polyurethane (TPU-1) obtained or obtainable by reaction of an isocyanate composition (IZ) comprising MDI with a polyol composition (PZ), wherein the polyol composition (PZ) comprises at least one polyol (P1) and a chain extender (KV1), wherein the polyol (P1) is selected from polytetrahydrofurans having an average molecular weight Mn in the range from 1200 to 2000 g/mol and the chain extender (KV1) is selected from the group consisting of 1,3-propanediol, 1,4-butanediol and 1,6-hexanediol and also to a process for producing a ski shoe or a part of a ski shoe from the thermoplastic polyurethane according to the invention and to the ski shoe or part of a ski shoe per se.

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.

The soft boot and liner include a moisture transfer system that includes an inner fabric layer carefully selected from technically advanced fabrics. A series of layers are provided outside the inner liner including foam material layers, spacer fabrics and breathable membranes, in various orders. Encapsulation technology and waterproofing are used as well. The outer fabric layer is also capable of working with the other layers to promote the transfer of moisture. Frothed foams and flocking with fibers are further characteristics of the present invention. The moisture transfer system is incorporated into a soft boot or skate or as a removable liner for a shell boot. Numerous other modifications and applications are disclosed.

A sports shoe including a shell, adapted to receive the foot of a user in use, provided with a longitudinal front opening adapted to facilitate the insertion of the foot of the user, a covering tongue to cover at least the front opening, the covering tongue including at least a first rigid portion, adapted to extend, in use, at least at the instep of the foot of the user, and which can be connected to the shell through fixing means. The tongue further includes at least a second rigid portion, adapted to extend, in use, at the front part of the lower leg of the user, the second portion being rotatable with respect to the first portion in the instep region of the foot of the user, the tongue further including selective locking means for selectively locking/unlocking the rotation of the second portion with respect to the first portion.

The invention relates to a combination of a downhill binding or downhill ski binding, in particular a front jaw of the downhill binding, and a ski boot. The ski boot (10) comprises a rigid ski boot shell (11) and a sole (1) of the ski boot comprising a front end (1b) of the sole, a rear end of the sole, an upper side (1a) of the sole and a lower side (1c) of the sole. The downhill binding comprises a front jaw (20) and a rear jaw, wherein the downhill binding comprises a bearing structure (2) for the sole (1) of the ski boot. The bearing structure (2) has an apex (5) which has a distance (X1), in the longitudinal direction (X), from the front end (1b) of the sole held in the downhill binding of at least 28 mm and at most 34 mm, and wherein the apex (5) exhibits a perpendicular distance (Y2) from the upper side (1a) of the sole of the ski boot held in the downhill binding of 19 mm±2 mm in at least one point.
