A clamping system for a component, especially for an article of footwear or a sports article, may include: (a) a first member; (b) a second member, (c) a pivot about which the first member and the second member are rotatable relative to each other; (d) a first bracket slidably movable along a first path on the first member and a second path, by a first distance, on the second member, when the first member and the second member are rotated relative to each other from a first angle to a second angle; and (e) at least a second bracket slidably movable along a third path on the first member and a fourth path, by a second distance, on the second member, when the first member and the second member are rotated relative to each other from the first angle to the second angle.

Footwear and footwear production process comprises steps that include the reuse of raw materials previously used in footwear or other sources. Such a process also provides for the reduction of waste and environmental impact as well as the elimination of water consumption. A footwear, also the object of the present invention, comprises renewable origin, natural, recycled and recyclable components, being a sustainable product, ecologically viable and inserted in the context of Circular Bio Economy. The footwear presents quality standards in accordance with standard technical standards of quality, overcoming challenges related to obtaining comfortable and simultaneously sustainable shoes.

A method for manufacturing three-dimensional items with flexible walls is provided, by method of a mold and counter-mold between which a volume corresponding to that of the item to be obtained is delimited. The item is made up of laminar parts which are mounted on a template that is fixed to the inner surface of the mold. The laminar parts are joined to one another by means of a material which is injected in molten state through a network of conduits delimited between the counter-mold, template and the facing edges of adjacent laminar parts. The template is made of an elastically deformable material and has a three-dimensional configuration.

A method for manufacturing waterproof and breathable shoes is provided. The method includes subjecting shoe sole materials to plastication and mixing, followed by cutting into pieces to be mold to form a shoe sole; stacking a knitted fabric as an outer layer, a polyurethane layer as a middle layer, and a knitted fabric as an inner layer sequentially into a mold for hot-pressing and shaping to form a shoe upper; and bonding the shoe upper to the shoe sole with an adhesive glue so as to form a shoe. The shoe is made flexible and light as the shoe upper is made up of two layers of knitted fabric bonded to a polyurethane layer. Moreover, the middle layer of the shoe upper includes a wavy structure, which is stretchable and helps improve waterproofness and breathability of the shoe upper.
