Disclosed is a waterproof shoe with an improved ventilation mechanism, designed to circulate air from the outside environment through the shoe in order to provide convective cooling to a wearer's foot. In a desired embodiment, the shoe may incorporate a pump-ventilation mechanism which, coupled with airflow channels incorporated in the upper, acts to establish continuous substantially one-way airflow through the shoe in a heel-to-toe direction while a user walks.

A method of making a moisture-permeable waterproof shoe includes: cutting a substrate to form a cut piece having a main body and two wing portions; ultrasonically welding rear mating edges of the main body, wing lateral edges of the wing portions, front and rear curved edges of each wing portion respectively to a front convex portion and a lateral connecting edge of the main body to form a shoe-like inner sleeve: sleeving the inner sleeve on a shoe last; coating an adhesive on an inner surface of an upper; sleeving the upper on the shoe last and heating the assembly to form a moisture-permeable waterproof foot cover; and fixing a bottom portion of the moisture-permeable waterproof foot cover to a sole.

Waterproof, breathable socks, booties, shoe inserts, and footwear assemblies containing the shoe inserts are provided. The booties and shoe inserts include a laminate of a seamless ePTFE membrane and at least one textile. The bootie is conformable over a range of sizes and shoe shapes, and may be shaped to fit numerous sizes and shapes of asymmetrical shoe lasts. The bootie may shrink to fit, or, alternatively, be stretched to fit, an asymmetrical last having a desired size to form a shoe insert. Such a conformable bootie eliminates the need to have multiple sizes of shoe inserts correlating to particular shoe sizes. In embodiments where the ePTFE is seamless and continuous, the shoe insert eliminates the need for a waterproof seam tape, which is conventionally used to make shoe inserts waterproof. Methods of forming the socks, booties, and shoe inserts are also provided

Provided herein are embodiments of a shoe component. The shoe component may include a toebox, an insole, an adhesive membrane, a thermal-resistant insert, a midsole, and an outsole. The insert may further include a footbed. The footbed may include an upper surface and a bottom surface. The insert may further include an upper laminate on the upper surface of the footbed and a lower laminate on the bottom surface of the footbed.

The disclosure relates to articles of footwear (100) and components thereof, including outsoles (112), which can be used in conditions normally conducive to the accumulation of soil on the outsoles (112). In particular, the disclosure relates to articles of footwear (100) and components thereof including an outsole (112) with a material (116) including a polymeric network formed of a plurality of polymer chains, where the material (116) defines external ground-facing surface or side of the outsole (112). The outsoles (112) can prevent or reduce the accumulation of soil on the footwear (100) during wear on unpaved surfaces such as sporting fields.

A method for manufacturing a waterproof and vapor-permeable shoe (1) (20) (30) (40) (50) comprising the steps of providing an upper (2) and a lining (3) comprising at least one functional layer (7) of vapor-permeable and waterproof material, providing an insole (5) comprising a functional support sheet (9) of vapor-permeable and waterproof material, coupling the peripheral edge of the functional layer (7) of the lining (3) to the peripheral edge of the functional sheet (9) of the insole (5) by way of a sealing waterproof adhesive (8) so as to shape a sock of vapor-permeable and waterproof material, couple the upper (2) to the outer surface of the lining (3) by way of a vapor-permeable adhesive; and couple a sole (4) to the upper (2) and/or to the lining (3) and/or to the insole (5).

The waterproof/breathable moisture transfer liner for a running and hiking shoe includes an inner liner selected from technically advanced fabrics which are carefully selected. A series of layers are provided outside the inner liner including foam material layers, breathable membranes, a supportive mesh or a moldable foam, and an outer shell fabric. The applicability of the liner to alpine, snowboard boots, cross country, hiking boots, protective gear and helmets, along with appropriate variations for each application.

Waterproof, breathable socks, booties, shoe inserts, and footwear assemblies containing the shoe inserts are provided. The booties and shoe inserts may include a laminate comprising a seamless extensible film, such as a polyurethane film, and at least one textile. The bootie is suitable for a range of sizes and shoe shapes. The bootie may shrink to fit, or, alternatively, be stretched to fit, an asymmetrical last having a desired size to form a shoe insert. A bootie having a seamless extensible film eliminates the need to have multiple sizes of shoe inserts correlating to particular shoe sizes. In embodiments where the polyurethane film is seamless and continuous, the shoe insert eliminates the need for a waterproof seam tape, which is conventionally used to make shoe inserts waterproof. Methods of forming the socks, booties, and shoe inserts are also provided.

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.
