Definitions

• the present invention relates to a waterproof and vapor-permeable shoe, provided predominantly by means of the working method known as "AGO lasting" .
• waterproof and vapor-permeable generally refers to the characteristic of tightness to water in the liquid state combined with permeability to water vapor.
• the part of the foot that notoriously has the greatest perspiration effect is the sole of the foot; the sweat that it produces saturates the air with moisture and mostly condenses, stagnating on the insock.
• 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.
• AGO lasting The working method usually called "AGO lasting” has already been known for a long time in the shoe industry and entails, with an operation called lasting, pulling the top assembly over the last, folding back its lower edges, known as lasting margins, below an insole to which they are perimetrically glued in order to be interposed partially between the insole and the sole that will be assembled thereon.
• 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.
• the assembly insole is made of a material that is flexible but structured enough not to be deformed because of the effect of the traction applied thereto by the lasting margins which are glued to it during lasting.
• the "AGO lasting" working method allows the penetration of water into the shoe through the outer layer of the upper and through the assembly insole.
• 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.
• the sealing of the sole to said membrane is, in fact, particularly difficult, because in the "AGO lasting" working method the bottom of the shoe is not smooth and flat, as for example in the case of a "Strobel” working method in which the edges of the insole are sewn to the edges of the upper or of the laminated lining with the membrane, but the lasting margins of the upper are superimposed on the assembly insole, creating irregularities along its perimeter.
• the creases that form as a consequence of the assembly of the toe and the heel of the upper on the assembly insole constitute true channels for water infiltration.
• shoes that have a waterproof and vapor-permeable insole that comprises a waterproof and vapor-permeable membrane, to which the lasting margins of a lining with a waterproof and vapor-permeable membrane are associated by means of a first lasting operation, have now been studied for years.
• the joining region between the lining with membrane and the insole is sealed by means of a waterproof sealing tape.
• the lasting margins of the outer layer of the upper are then associated, by means of a second lasting operation, with the waterproof and vapor-permeable insole.
• the execution is not without aspects that can be perfected, since the water absorbed by the outer layer of the upper and wicked inside may stagnate below the waterproof insole.
• this construction suffers a further drawback if a sole with openings is used, because the water might enter from said openings and wet the lasting margins of the upper, soaking it and then rising toward the foot insertion region.
• the gasket is made of waterproof and non- vapor permeable material, this construction is unsuitable with a sole made of rubber that is rendered impermeable to water in the liquid state and permeable to water vapor by means of open regions or perforated regions covered and sealed with a waterproof and vapor-permeable membrane.
• the gasket is pierced at the vapor-permeable region of the sole, in order to allow the outflow of the water vapor generated by perspiration, the lasting margins of the outer layer of the upper would drag water into the shoe and such water would migrate on the insole indeed through the holes in the gasket.
• 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.
• the sock-like lining comprises an opening for the foot and is generally defined by two lateral portions and a lower portion, which are joined by means of zigzag and/or Strobel seams and sealed by means of a waterproof sealing tape.
• the aim of the present invention is to provide a waterproof and vapor-permeable shoe that allows to prevent the infiltration of water between the assembly insole and sole, being structurally easier than currently known waterproof and vapor-permeable shoes.
• an object of the invention is to devise a waterproof and vapor-permeable shoe provided predominantly according to the method known as "AGO lasting" that has an effective and durable seal of the assembly insole made of waterproof material, which has at least one vapor- permeable or perforated portion, to the sole.
• Another object of the invention is to provide a waterproof and vapor- permeable shoe that is effectively and durably waterproof and at the same time effectively vapor-permeable through its upper and through its sole and has a waterproof sealing structure that is simple and easy to provide.
