Abstract: A reinforced skate including a frame for supporting wheels or an ice-skating blade, and associated with a shoe. The reinforcement includes a first rigid element and a second rigid element, which are articulated to each other and surround the quarter and the shell so as to laterally assume the shape of the Greek letter lambda. The first rigid element is connected, at its end, to the frame so as to form a structure which allows optimum transmission of forces to the frame.

Abstract: A fastening device for sports shoes, such as ski boots or skates. The device comprises a plastic body and a metal element which constitutes a containment frame for the plastic body. The metal element can thus be interlocked with the plastic body, so as to obtain a device that has high stress resistance despite having a low weight and cost.

Abstract: A ski boot having a rear quarter which is constituted by a first half-quarter and by a second half-quarter which are mutually articulated and oscillate with respect to the shell. The second half-quarter is also articulated to the shell. The half-quarters interact with adjusting members for adjusting their mutual position, so as to achieve a better adaptation and embracing of the rear region of the lower part of the leg while skiing.

Abstract: A support adjustment device for ski boots composed of a shell with which at least one quarter is associated. The peculiarity of the device consists of the fact that a shaped body is elastically associated with the quarter and embraces at least one portion of the skier's leg. The device furthermore includes sliders suitable for limiting the backward stroke of the shaped body with respect to the quarter. A safe and constant support of the calf is thus obtained.

Abstract: Securing and adjuster device for ski boots, composed of a circular winder, which is actuated by a knob and is connected for example to a foot presser, and of a vertical lever, which actuates a cable for closing the quarters; when the lever is opened, the winder is also released automatically; the adjustment of the two devices is independent.

Abstract: The ski boot includes a front quarter and a rear quarter associated with a shell, as well as a first device and a second device which are distinct and adjacent and separately secure the foot inside the boot and close the quarters. The rear quarter has, in a rearward position, a perimetric edge which is depressed upward and at which an end of a flap is arranged; one of the first or second devices being associated with the end of the flap. The flap and/or the first device and/or the second device are thus pivoted, along at least one transverse axis, to the rear quarter.
