A waterproof shoe structure includes a sole, a vamp mounted on the sole, and a waterproof lining mounted on the vamp. The vamp is provided with a plurality of vent holes. The waterproof lining has a surface provided with a plurality of convex portions and a plurality of concave portions between the convex portions. Each of the convex portions is higher than each of the concave portions. Each of the convex portions is provided with a through hole connected to each of the vent holes of the vamp. The through hole of each of the convex portions and each of the vent holes of the vamp are integrated to connect an inner space of the vamp to an ambient environment.

A rain boot and uniform footwear with an intelligent temperature-controlling air extractor and water-proofing and air-venting functions, includes: a boot upper layer (10), a middle cushion layer (11) and a boot lower layer (12), wherein a miniature air extractor (13) is provided at a position below an instep of the boot bottom layer (12), a magnetic levitation power switch (14), a temperature sensor (15) and a control main board (16) are also provided in the boot bottom layer (12), the temperature sensor (15) being electrically connected to an input end of the control main board (16) and transmitting a temperature sensing signal of the foot to the control main board (16), and an output end of the control main board (16) being electrically connected to the miniature air extractor (13) via the magnetic levitation power switch (14).

The waterborne bonding layer structure between sea fishing trouser legs and shoes or boots includes a waterproof fabric layer, a bonding layer, and a fabric layer. The waterborne bonding layer bonds the waterproof fabric layer and the fabric layer together into one body. Besides, the bonding layer includes a plurality of foaming holes, each of which is smaller than the diameter of general liquid molecules and larger than that of general gas molecule, so that when an angler wears the fishing trousers, water droplets do not infiltrate into the inside of the fishing trousers while air can pass through the forming holes, thus reducing the occurrence of dew condensation and preventing uncomfortable wet and cold caused therefrom, achieving excellent waterproof and ventilating effects, and maintaining the wearing dryness for a long time, which greatly improves the comfort of the angler when wearing the sea fishing trousers of the invention.

A footwear assembly includes a shoe having a vamp and an outsole. The shoe includes a first room defined between the vamp and the outsole, and a first opening is formed in the top of the shoe and communicates with the first room. A first connection member is located on outside of the first opening. A water-proof sock is inserted in the first room via the first opening, and has a neck portion formed along the second opening of the water-proof sock. The neck portion is able to be foldable relative to the water-proof sock and has a second connection member which is connected to the first connection member when the neck portion is foldable relative to the water-proof sock.

The name of the invention: One-way membrane with a barrier protection, which ensures the function of permeability even in the case of contradirectional mechanical pressure, and the method of its manufacture. The invention relates to a single-layer or multilayer membrane (1) with through apertures (2), whose face layer (1) is connected with thin flexible plastic or rubber segments (3) overlapping the apertures (2) and allowing the air or fluid to flow only in the direction from the underside layer (12) of the membrane (1) to the face layer (11) of the membrane (1), as check valves/flaps in the number of up to 30 pieces per 1 cm.sup.2. It further relates to the method of manufacturing the membrane (1).

A water resistant footwear having an upper made of a water vapor transpiring material resistant to water with a first extreme flap and at least a portion having a first thickness and provided with a second extreme flap. The first flap and the second flap have relative second thicknesses lower than the first thickness of the portion and are superimposed on each other with the interposition of a thermo-double-sided adhesive layer which can be activated by raising the temperature. The first flap and the second flap superimposed are fixed to each other by thermo-sealing. Furthermore, the footwear has an insole fixed to an edge of the upper and a waterproof sole obtained by direct injection molding on the upper and arranged so as to cover one face of the insole and seal it.

A method of attaching at least two pieces of fabric in a waterproof fabric product. The at least two pieces of fabric are attached at a seam. The seam subsequently is sealed by application of a sealing tape. The method includes attaching the at least two pieces of fabric to each other by a welding process to form a welded seam, and performing the sealing by applying the sealing tape to cover the welded seam at one side of the fabric. A waterproof fabric product that has been produced using the method of attaching at least two pieces of fabric. A footwear includes a membrane including at least two pieces of fabric that are attached at a seam.

A method of manufacturing a shoe structure includes: a setting step of setting an upper on a shoe last, and distributing a foam matrix material comprising a plurality of semi-foamed granules of thermoplastic polyurethanes (TPU) along a bottom of the shoe last to position the foam matrix material between the shoe last and the upper, and a foaming step of heating the shoe last with the upper and the foam matrix material thereon by microwave, so that the semi-foamed granules are foamed to form an insole bonded to the upper, and the upper is shaped along a contour of the shoe last after cooling and removing the shoe last.
