Abstract: A lever fastening device comprises a lever articulated to a base about a first axis and formed in two adjoining portions of which the first has one of its ends articulated to the base on the first axis whereas the second portion is articulated to the opposite end of the first portion about a second axis; a tie element is connected to the second portion in a position spaced from the second axis on the opposite side to the first axis.

Abstract: Sport footwear with a shell, a bootleg, and a device for clamping the heel region of the shell tight, including an eave pivoted on the shell and an anchor member which is associated slidingly with the bootleg, and a tie member between the sliding anchor member and the eave for swinging the eave into a working position in a way which is operated directly by operating the fastener for the bootleg.

Abstract: An article of sport footwear with a shell formed with two, respectively forward and rearward, longitudinally opposite openings which extend from a shell entrance and identify two lateral sides, with a bootleg pivoted on the shell and at least one fastening device bridging the corresponding opening and being adjustable in length, whose opposite ends are anchored on respective lateral sides of the shell proximate to the entrance to limit the rearward swing range of the bootleg and/or the forward flex of the boot.

Abstract: An article of sport footwear in particular a ski boot, with a boot shell in which a boot entrance is defined for receiving the skier's leg, and with a plate-like lug associated with the shell at the location of the entrance to provide predetermined conditions of support for the skier's leg, wherein the lug is pivotable relative to the shell into at least two working positions where it presents different portions to the entrance, thereby varying the support conditions provided for the skier's leg accordingly.

Abstract: A sport shoe such as a ski boot having a shell with a notch extended to near the toe region thereof and a strip bridging the notch and being adapted to be tightened onto the shell to close it, is provided with a toe piece adapted to overlie the shell at the toe region; the toe piece has a lug which intervenes, in use, between the strip and the shell to tighten the toe piece onto the shell through said strip.

Abstract: On a ski boot provided with a shell defining a quarter and a spoiler mounted to the quarter, there are provided first and second adjusting devices active between the spoiler and the quarter to controllably shift the spoiler along two directions substantially perpendicular to each other.

Abstract: A ski-boot heater has a heating resistor and a battery mounted in the boot and a socket is provided in the boot for connecting the resistor and the battery to an external voltage source. A control circuit enables the battery to be recharged with direct current when the socket is connected to an external AC or DC supply and when the battery is being recharged enables the resistor to be supplied with electrical power greater than that normally supplied to the resistor by the battery.

Abstract: The rear-entry ski boot disclosed herein includes a substantially rigid outer foot portion and a relatively movable leg portion, the foot portion having an inner lining with at least one inflatable air pocket interposed between the foot portion and the inner lining. A pump operable by bending movements of the leg portion is provided for inflating the air pocket.

Abstract: A ski boot having a jointed lockable leg portion includes a sole suitable for walking on ice or snow. The boot has a normalized sole attachment compatible with most ski bindings and having at least one bottom opening for the discharge of ice or snow accumulating between the foot portion of the ski boot and the normalized sole. The ski boot and normalized sole have rear interlocking elements and front pressure-releasable locking parts.

Abstract: A ski boot possesses a foot portion and sole constructed for comfortable and easy walking. A separately formed normalized sole attachment for the ski boot interlocks securely therewith and renders the boot compatible to substantially any ski binding.

Abstract: A ski boot consists of a foot portion and a leg portion connected in articulated relationship. A stiffening element at the front of the boot formed of resilient material has substantially the profile of the boot and is attached at least partially to the foot portion and/or the leg portion thereof.

Abstract: Closing straps for a ski boot formed of plastics material have corresponding ends adjustably secured by pulling levers fixed on one flap of the boot upper. The ends of the straps remote from the pulling levers are releasably connected with projection elements on the other flap of the upper integrally formed with such flap from the same plastics material from which the upper is made by injection molding.

Abstract: Sporting footwear, such as a mountain boot or hockey boot or training boot, formed of injected plastics, has integral lacing projections formed on overlapping front closure flaps forming parts of the boot upper. The integral projections provide for easy zigzag lacing of the boot with security and economy of manufacturing. Protrusions integrally formed on the boot upper between adjacent pairs of lacing projections and spaced from the projections bear frictionally on the lace engaged with the integral projections. Tightening of the lace is enhanced while the lace is under tension and loosening of the lace is hindered when the lace is slackened and has its cross section increased.
