The present technology relates generally to a footwear assembly and method of manufacturing said footwear assembly. The footwear assembly includes an outsole and an upper connected to the outsole, where the upper includes a neoprene sock, a vulcanized rubber layer, and an injection molded layer. The neoprene sock is a full-foot neoprene sock having a foot portion that is configured to receive a wearer's foot. The vulcanized rubber layer fully covers a vamp portion, heel portion, toe portion, and ankle portion of the neoprene sock while only covering some of an underfoot portion. The injection molded layer is formed over a portion of the vulcanized rubber layer and completely covers the underfoot portion of the neoprene sock.

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 waterproof sock cover apparatus for keeping feet warm and dry in any boot includes a sock body having a foot portion and a cuff portion. The foot portion is configured to receive a user's foot wearing a standard sock and the cuff portion is configured to extend above the standard sock and below a user's knee. The sock body comprises a breathable and soft inner layer, an insulating medial layer continuously disposed around the inner layer, and a waterproof outer layer continuously disposed around the medial layer. A sole is coupled to a bottom side of the foot portion. An elastic band is coupled to the sock body within an upper perimeter of the cuff portion. The elastic band and the surrounding sock body define an elasticized collar configured to secure a user's leg. The sock body is configured to be worn within a boot.

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.

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.

A fishing garment (1), namely for whitewater fishing, includes, on the one hand, waterproof pants (2), which include two legs (3), on the other hand, a pair of waterproof walking boots (4) and, yet on the other hand, fastening means (5) for fastening, in a tight and reversible way, the two legs (3) of the pants (2) each to one of the boots (4), in an active fastening position, yet on the other hand, immobilization means (6) for immobilizing, in a reversible way, the two legs (3) of the pants (2) each relative to one of the boots (4), in the active fastening position, and also on the other hand, means for making integral (8) for making integral these immobilizing means (6) and these walking boots (4).

A disposable overshoe preferably made from a single-ply sheet of waterproof material folded on top of itself to form a double ply-sheet with a fold at the bottom. The toe of the disposable overshoe can be made by fusing the double-ply sheet to itself to form a toe-side connection running from the fold at the bottom to an opening between the double-ply sheets at a top. Likewise, the heel of the disposable overshoe can be made by fusing the double-ply sheet to itself to form a heel-side connection running from the fold at the bottom to the opening at the top. By orienting and forming the toe-side and heel-side connections to the size and shape of a shoe, an opening at the top can be left to allow a shoe to fit between the opening in the double-ply sheet. In this way, a user can insert the toe of the user's shoe into the opening, and cinch a strap around the user's leg to protect the inside of the disposable overshoe from the outside elements.

A waterproof and vapor-permeable sole for shoes, including: a first contoured element including at least one hollow lower portion in the plantar region, delimited by a border and including at least one through opening, at least one second contoured and flat element, which is joined in a lower region with respect to the first element; at least one functional element substantially in sheet form, which is waterproof and vapor-permeable and is joined in an upper region to provide a seal to the first element. The second element has a shorter extension than the respective hollow lower portion to define with the border a surrounding slot.
