Abstract: Laminated composite material usable to make articles of manufacture, such as boots or other sports articles in particular. The laminate is a new basic material particularly directed to articles of manufacture having drastic mechanical requirements and which are very inexpensive and lightweight. The laminate has a sandwich structure having a core between two layers. More particularly, the core and the two layers are composites, and at least a portion of the fibers of the core have a mechanical strength significantly lower than that of at least a portion of the fibers of one and/or the, other layers. In a particular embodiment, the laminate has a thickness of 3 mm or less. The layers are sheets of carbon fabric embedded in an epoxy resin, and the core is made from non-woven polyamide micro-fibers having a thickness equal to 0.32 mm. The invention also relates to the manufacture of the laminate.

Abstract: A liner having a single foot entry for a rigid shell sport boot, constituted of an upper enveloping the foot and the malleoli and of a top portion of the upper that covers the user's lower leg. The top portion of its upper has a composite structure formed of a plurality of comfort elements coupled together and fixed to a relatively thin support envelope that extends on the exterior, and each comfort element is made from a material having a specific density and degree of firmness that are different from those of the element to which it is coupled. The differentiation of the characteristics of the elements with respect to one another allows transmitting the impulses from the user's lower leg to the boot shell in preferred predetermined directions in correspondence with selected support zones on the lower leg.
