Abstract: A insole (1) having puncture-resistant properties for safety footwear, comprising an anterior portion (2) extending from a toe region (3) to a metatarsal region (4) of the insole and a posterior portion (5) extending from the metatarsal region to a heel region (6) longitudinally opposite the toe region. The posterior portion (5) comprises at least one substantially rigid layer (8) made of composite material formed from a fibre-reinforced polymer matrix and the anterior portion (2) is formed of a substantially flexible material comprising at least one layer (7) formed of polymer fibres having enhanced puncture-resistant properties.

Abstract: The sports footwear described comprises a first and a second footwear element (4, 5) such as an outer upper portion and an inner shoe, one of the elements having, on the corresponding surface facing the other element, at least one localized projection (22-27) which can be housed substantially with shape coupling in a recess (12-17) localized in a corresponding position in the other element so that the elements are connected to one another by the coupling of each projection in the corresponding recess.

Abstract: Integrated attachment for cross country skis, which is suitable to connect ski boots (17) to the surface (35) of a cross country ski (34), the ski boot (17) comprising a main anchorage pin (20) clamped resiliently in a slot (25) included in the integrated attachment (10), with which (10) there cooperates a contrast thrust spring means (33), the attachment (10) comprising a support (11) with wings (36) that bear an oscillation pivot (12) positioned at a right angle to the ski (34) and supporting an oscillatory connector (26) with which the ski boot (17) can oscillate vertically, the oscillatory connector (26) extending before and behind the oscillatory pivot (12) and having an L-shaped form with its vertex on the axis of the oscillation pivot (12) situated in a part below the boot (17) and under the front part thereof (17), the contrast thrust spring means (33) opposing the oscillation movement of the oscillatory connector ( 26) by acting on a first frontal side (127) of a frontal body (27).

Abstract: Toe for long-distance skiing boots (10) of which the sole is conformed as required, a recess (23) to accommodate an elongate replaceable element (22) being comprised in the front lower portion of the boot (10).

Abstract: A cross country ski rear fastening includes a body fixed on the ski, a resiliently biased fork member movable on the body for locking the footwear heel, and a lever system operable by the skier and connected with and acting on the fork member to cause engagement of the latter with the heel on overcoming a dead center position of the lever system and the biasing force on the fork member.
