A zipper-free moisture-permeable waterproof high-top shoe includes a high-top inner sock body having a first foot portion and a first leg portion cooperating with each other to define a foot space. A moisture-permeable waterproof high-top shoe-like sleeve is sleeved on the high-top inner sock body and has a second foot portion. A moisture-permeable waterproof low-top shoe-like sleeve is sleeved on the second foot portion and has a sleeve body. A high-top outer sock body is sleeved on an assembly of the inner sock body, the high-top shoe-like sleeve and the low-top shoe-like sleeve, and has a third foot portion. A sole is fixed to a bottom portion of the third foot portion.

A multi-style moisture-permeable waterproof shoe includes an outer shoe body unit defining an insertion space, and a plurality of sock-like inner shoe body units inserted removably and selectively into the insertion space. Each sock-like inner shoe body unit includes a moisture-permeable waterproof shoe-like inner sleeve and an outer sock body. The shoe-like inner sleeve defines a foot space and is made from at least one cut piece. The outer sock body has a sock body portion sleeved on the shoe-like inner sleeve. An inner adhesive layer is adhered between an outer surface of the shoe-like inner sleeve and an inner surface of the sock body portion.

A multi-style comfortable shoe includes an outer shoe body unit defining an insertion space that has an open top end and a closed bottom end, and a plurality of sock-like inner shoe body units inserted removably and selectively into the insertion space. Each sock-like inner shoe body unit includes a shoe-like inner sleeve and an outer sock body. The shoe-like inner sleeve defines a foot space that has an open top end and a closed bottom end and is made from at least one cut piece. The outer sock body has a sock body portion sleeved on the shoe-like inner sleeve. An inner adhesive layer is adhered between an outer surface of the shoe-like inner sleeve and an inner surface of the sock body portion.

A double structure comfortable moisture-permeable waterproof shoe includes an outer shoe body unit including an outer shoe upper, a midsole and an outsole. The outer shoe upper and the midsole cooperatively define an insertion space. A sock-like inner shoe body unit is disposed in the insertion space and includes a moisture-permeable waterproof shoe-like inner sleeve, an outer sock body having a sock body portion sleeved on the shoe-like inner sleeve, and an inner adhesive layer adhered between an outer surface of the shoe-like inner sleeve and an inner surface of the sock body portion. A connecting layer is fixed between the outer shoe upper and the sock body portion and between the midsole and the sock body portion.

A process for welding porous membranes, the process containing i) providing first and second porous membranes; ii) at least partially superimposing the first and second porous membranes to obtain an at least partial superimposition region; iii) welding the first and second porous membranes at least in a portion of the at least one superimposition region at a temperature in the range from 100 to 300 C. to obtain an at least partially welded composite of the first and second porous membranes, wherein the first and second porous membranes are made of at least one thermoplastic elastomer selected from the group consisting of a polyurethane elastomer, a polyester elastomer, a polyetherester elastomer, a polyesterester elastomer, a polyamide elastomer, a polyetheramide elastomer, a polystyrene elastomer, and an ethylene-vinyl acetate elastomer, and wherein the first and second porous membranes have pores having an average pore diameter of less than 2000 nm.

Here are described multilayer textile assemblies for use in footwear and methods of production thereof. Also described are footwears and boot liners comprising the multilayer textile assemblies.

A zipper-free moisture-permeable waterproof high-top shoe includes a high-top inner sock body having a first foot portion and a first leg portion cooperating with each other to define a foot space. A moisture-permeable waterproof high-top shoe-like sleeve is sleeved on the high-top inner sock body and has a second foot portion. A moisture-permeable waterproof low-top shoe-like sleeve is sleeved on the second foot portion and has a sleeve body. A high-top outer sock body is sleeved on an assembly of the inner sock body, the high-top shoe-like sleeve and the low-top shoe-like sleeve, and has a third foot portion. A sole is fixed to a bottom portion of the third foot portion.

In certain aspects, the inventive subject matter is directed to production of constructs of footwear and components thereof by jet extrusion. The inventive subject matter contemplates novel processes for making such constructs using jets or streams of materials that solidify as fibers, and which form into two- or three-dimensional webs as they are collected. The webs may be in the nature of films, membranes, or mats. In some embodiments, the inventive subject matter generally relates to nonwoven textiles consisting of webs of superfine fibers, i.e., fibers with diameters in nanoscale or micronscale ranges.

The invention relates to a functional footwear unit, in particular in the form of knit-of-parts, which has preferably a particularly modular protective function against chemical and/or biological toxic and/or harmful substances, especially warfare agents. The invention also relates to the uses thereof.
