Definitions

• Figure 4 is a sectional view of a second variation of a component of the sole in Figure 2;
• Figure 7 is a sectional view of a third embodiment of a sole according to the invention.
• the functional layer 13 comprises a layer 20 for protecting the membrane 17 and/or the support 19, arranged in a lower region, made of vapor-permeable material and capable of drying rapidly, such as felt of non- woven fabric, conveniently treated to be water-repellent.
• the protective layer 20 and the membrane 17 and/or the support 19 are advantageously mutually coupled, for example, by spot gluing by using a commercially available adhesive that is resistant to hydrolysis (the type commonly known as "hot melt” or systems with calendered powders).
• the portion of the functional layer 13 left free of the polymeric material of the upper component 14 continues to work by osmosis.
• the sealing of the lower component 1 1 can be created by perimetric gluing with hydrolysis-resistant glues.
• Such insert 16 in this case, also comprises, in addition to the functional layer 13 and the upper component 14, an element 25, which affects perimetrically the edge regions of the functional layer 13.
• the membrane 17 and/or the support 19, together with the protective layer 20, of the functional layer 13 are sealed at the edge regions to the element 25, made of polymeric material (for example thermoplastic rubber or polyurethane), adapted to define for them a support both during assembly step and during working step.
• polymeric material for example thermoplastic rubber or polyurethane
• the shoe 23 further comprises, in this case, an insole 26 made of vapor-permeable and/or perforated material (for example natural leather, felt or cellulose material), which can be associated optionally with a heel seat made of soft leather with absorbent rubber latex, not illustrated.
• an insole 26 made of vapor-permeable and/or perforated material (for example natural leather, felt or cellulose material), which can be associated optionally with a heel seat made of soft leather with absorbent rubber latex, not illustrated.
• the insole 26, in this case, is joined to the upper 22 by way of a seam 28 of the strobel type.
• the element 125 that seals the functional layer 113 at its edge regions has an upper surface that is free from pumping elements 1 15.
• the upper component 214 with the pumping elements 215 is pre-molded and then assembled by gluing with sealing to the functional layer 213, so as to form an insert to which the lower vapor- permeable component 11 is joined by gluing with a perimetric seal or by co- molding.
• the element 325 that seals the functional layer 313 at its edge regions is constituted by a ring-shaped element, made for example of ethylene vinyl acetate (EVA).
• EVA ethylene vinyl acetate
• the whole insert 16, 1 16, 216, 316 can be made modular so that it can be used on different types of sole and on different sizes.
• a third embodiment of a sole according to the invention is fully similar to the sole 10 and is generally designated by the reference numeral 500.
• the sole 500 has means for protecting the functional layer 513, which are constituted by a composite lower component 51 1.
• the lower component 511 comprises a waterproof portion 51 la in contact with the ground and a portion 51 1b made of porous material with open pores in order to allow the passage of air and/or water vapor through it.
• the part 51 1b makes contact with, or in any case faces, the membrane 517 and/or the support 519 of the functional layer 513, to which it is joined at least in the edge regions (in which a seal is provided).
• the part 511b is completely permeable and therefore allows the permeation of the perspiration that has formed inside the shoe.
• the materials used may be any according to requirements and to the state of the art.
