Abstract: A sports shoe includes a shell formed of a first shell portion and of a second shell portion, distinct from each other and adapted to be assembled together. The first shell portion includes a first peripheral rim edge and the second shell portion includes a second peripheral rim edge including, respectively, a first joining rim portion and a second joining rim portion adapted to be coupled together. Specifically, the first joining rim portion includes at least a joining channel adapted to cooperate with a corresponding at least a joining projection included in the second joining rim portion. The joining channel and the corresponding joining projection are fixable to each other by means of heat welding.

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: Method for manufacturing pumping devices, particularly usable in sports shoes, including the monolithic molding of a body having at least one tubular passage and a first and a second seat for air venting and intake valves. The body furthermore includes at least one chamber with a partially open elastically deformable wall. The method entails the closure of the chamber, whereas the valves and at least one inflatable plenum chamber are associable within the body thus obtained, before closing it. The pumping device thus obtained has optimum functional characteristics as well as very low manufacturing costs.
