Definitions

• shoes are currently known with different type of soles made of rubber which are impermeable to water in the liquid state and permeable to water vapor and are obtained by using a vapor- permeable and waterproof membrane sealed to the body of the sole so as to cover through openings thereof.
• the assembly of the sole consists in joining the sole to the upper part of the shoe, by gluing or direct injection in a mold.
• the "AGO lasting” working method is generally used for shoes of the type classified as classic or elegant.
• a need that is particularly felt in the production of shoes with waterproof and vapor-permeable membrane, in the top assembly, consists in obtaining an effective seal of the joining regions between the assembly insole, the lining with membrane, the outer layer of the upper and the sole, in order to avoid even the slightest water infiltration from outside.
• An insole is applied to the bottom of the sock and the lasting margins of the outer layer of the upper are folded back and glued perimetrically thereon.
• a waterproof and vapor-permeable shoe characterized in that it comprises
• an assembly insole made of waterproof material, which has at least one vapor-permeable or perforated portion above said vapor permeation region which, once assembled, it covers,
• Figures 1, 2, 3a, 4, 5, 6, 7, 8 and 10 are a simplified diagram of a detail, shown in cross-section, of a waterproof and vapor-permeable shoe provided in different embodiments, according to the invention
• Figures 11 , 12 and 13 are sectional views of soles of waterproof and vapor-permeable shoes provided according to the invention in different embodiments.
• an assembly insole 13 made of waterproof material, which has at least one vapor-permeable or perforated portion 14 above the vapor permeation region 12, 112 which, once assembled, it covers,
• a sealing region A is provided at which the assembly insole 13 is sealed in a waterproof manner to the sole 11 or 111, the sealing region A further substantially surrounding the vapor-permeable or perforated portion 14 which remains free for vapor permeation.
• the lasting margin composed of the joined lower edge 17a and lower rim 18a protrudes from the lower flap 16a of the lining 16 by approximately 10-15 mm.
• the assembly insole 13 may be provided with a vapor-permeable layer that covers its face directed toward the foot insertion region B and constitutes a unit with it.
• the sole 11 is sealed in a waterproof manner to the upper assembly
• the sealed connection between the sole 11 and the assembly insole 13 is direct
• sealing element 21 it is advantageously made of waterproof and heat-activated polymeric material that is made to adhere intimately so as to form a seal to the lower rim 18a and to the sole 11, mutually sealing them.
• Another function of the sealing element 21 is to strengthen the lower rim 18a of the upper membrane 18 while allowing its sealing to the sole 11.
• the lower flap 16a of the lining 16 and the lower rim 18a of the upper membrane 18 are joined conveniently quite coincident, the lower flap 16a being skived so as to expose the lower rim 18a, which, being exposed through the lower flap 16a, is folded back and glued so as to form a seal, at least predominantly according to the working method known as "AGO lasting", under the perimetric edge 13a of the assembly insole 13.
• the vapor-permeable or perforated portion 14 is advantageously defined by one or more localized regions of the assembly insole 13, when the vapor permeation region 12 affects corresponding localized regions of the sole 11.
• the lasting operation can occur manually by using suitable pliers.
• An auxiliary gasket 23 advantageously surmounts and straddles the assembly insole 13 and the lower edge 18a, sealing them to each other in a waterproof manner.
• the lasting operation may occur manually by using suitable pliers.
• the sole 11 is sealed in a waterproof manner to the upper assembly
• the assembly insole 13 is made of waterproof polymeric material, the vapor-permeable or perforated portion 14 having a plurality of holes 14a that pass through its thickness.
• the plantar insert 25 comprises at least one membrane made of expanded polytetrafluoroethylene, e-PTFE, or polyurethane, PU, or similar materials, that optionally has meshes associated on its faces.
• the assembly insole 13 is conveniently reinforced upward with a shank 27, which is vapor-permeable or perforated at least at the vapor permeation region 112 of the sole 111.
• the assembly is hot pressed in order to promote its bonding, thus saving the drying time of the polyurethane adhesive.
• the invention fully achieves the intended aim and objects, by providing a waterproof and vapor-permeable shoe that allows to prevent the infiltration of water in the foot insertion region, thanks to the seal between the assembly insole and the sole, and is structurally simpler than currently known waterproof and vapor-permeable shoes.
