A comfortable, flexible Nordic ski boot with embodiments for classic, skate, combi, and roller skiing enables full ski control while remaining comfortable and allowing movement to help avoid overuse injuries including compartment syndrome. The boot provides precise fit at the heel and ball of the foot while allowing flexible movement. In embodiments, a strap attaches the ball of the foot. A custom heel fit and/or a strap can attach the heel. A removable, adjustable cuff can limit eversion and inversion. Some embodiments are made on multiple lasts, provide toe box room, provide partial or full movement about the ball of the foot, and/or allow twisting between the heel and ball of the foot. Embodiments are configured to elastically return to a flat configuration after flexing, while remaining in alignment with a ski. The sole can include carbon fibers and/or elastic cords, spring cables, and/or such like to enhance elasticity.

A ski boot is provided of the type comprising a substantially soft inner liner, a substantially rigid outer shell and a cuff articulated to the shell, and further comprising a spoiler articulated to the shell and arranged between the inner liner and the cuff. The ski boot comprises a locking device for selectively allowing or preventing rotation of the cuff relative to the shell and, at the same time, for selectively allowing or preventing the movements of the spoiler relative to the cuff, and consequently also relative to the shell.

A base is provided for a ski boot comprising a sole and an outsole element that is positioned in a predetermined position relative to a longitudinal axis (L). The outsole element is positioned on the sole by using two projections that are carried by one or other of the sole and the outsole element and that locate in holes or cavities defined by the other. Preferably, the projections are carried by the outsole element and locate in holes or cavities defined by the sole. The projections may be integrally formed with the outsole element or the sole. Alternatively, they may be formed by injected pins, rivets, fasteners, t-nuts, or screws.

An antistatic sport device includes a basic body and a basic element placed at the basic body, made of a running surface layer and side edges. At least one of the side edges forms a contacting surface that can be turned towards the terrain. Between a rear surface of the running surface layer and the basic body, a contacting element made of an electrically conductive material is placed at least in sections. The running surface layer is electrically conductively connected to the contacting element via a discharge path and further the contacting element to the contacting surface formed by the at least one side edge. Further, a sport system has antistatic function and a sport clothing system is for such sport system.

The invention relates to a ski boot with an element in shell form, which at least partially consists of a plastics compound material, wherein the compound material comprises a mixture of caprolactam polyamide and ionomers, and to a method for the production thereof, such that cations and anions of the ionomers form ion bonds, wherein elastic components of the compound material form a physical network that is soluble between 60 C. and 100 C., and so the element in shell form of the ski boot that at least partially consists of the compound material can undergo thermoforming below 100 C.

A ski boot with an element in shell form at least partially contains a plastic compound material. The compound material contains a mixture of caprolactam polyamide and ionomers, such that cations and anions of the ionomers form ion bonds. Elastic components of the compound material form a physical network that is soluble between 60 C. and 100 C., and therefore the element in shell form of the ski boot at least partially containing the compound material can undergo thermoforming below 100 C.

Sole (20) for a sports shoe, notably for a cross-country ski boot, comprising a first component (1) acting as a framework and at least one second component (21) assembled with the first component (1), characterized in that the second component (21) comprises an anterior part (32) extending substantially longitudinally in the anterior part of the sole (20).

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.

Ski boot sole (10), characterized in that it comprises: a plate (11) made of a composite material comprising reinforcing ribs (20); rear (30) and front (40) components extending under the plate (11) and forming gripping tread patterns (35, 45).
