A waterproof and moisture-permeable shoe upper includes a fabric upper layer, a waterproof and moisture-permeable membrane material middle layer, and an inner fabric lower layer. The fabric upper layer has anti-wicking treatment, and the waterproof and moisture-permeable membrane material middle layer is made of degradable thermoplastic elastomer. The upper layer, the middle layer of the waterproof and moisture-permeable membrane material, and the lower layer of the inner fabric are laminated through high temperature and hot pressing to form a wide-width layered composite material. Then the wide-width layered composite material is cut or hot pressed to form an upper, and the anti-wicking index of the shoe upper ≤1 cm/ In 2 hours, the moisture permeability of the shoe upper is greater than or equal to 10,000 g/(m.sup.2.Math.24 h), and the hydrostatic pressure of the shoe upper is greater than or equal to 10,000 mmH.sub.2O.

A double-layer footwear, especially a water sport footwear, comprises: an outer rubber foam panel defining a first joint member in an outer seam in the outer rubber foam panel, and an inner rubber foam panel defining a second joint member in an inner seam in the inner rubber foam panel and adhered with the outer rubber foam panel with an adhesive, with the second joint member being projectively separated from the first joint member with a barrier distance, to thereby securely preclude water penetration through the outer and inner seams into a wearer's foot.

Upper components for footwear include: (a) a first upper component that includes a first layer having a first material as a first filament including first plural, non-intersecting, spaced apart path segments (wherein the first filament has a width dimension of less than 3 mm wide (and in some examples, less than 2 mm wide, less than 1.5 mm wide, less than 1 mm wide, or even less than 0.75 mm wide)); and (b) a second upper component including a fabric element formed at least in part of a fusible material, wherein the fusible material of the second upper component is fused to the first material of the first upper component (e.g., in an adhesive-free manner). Additional layers of material, including additional layers including filament and/or fabric elements, e.g., of the types described above, may be included in the upper.

The object of the invention is a functional protective material, especially with the function of protecting against chemical and/or biological poisons and/or noxious materials, such as combat agents, wherein the functional protective material comprises a multilayer construction. The multilayer construction has a two-dimensional backing material, especially a textile backing material and a membrane, which is assigned to the backing material and, in particular, is connected therewith. The membrane is provided with a reactive finish, especially with a component having catalytic activity preferably with respect to chemical and/or biological poisons and/or noxious matter. The adsorption filter material is suitable particularly for use in ABC protection objects (such as ABC protective clothing).

A shoe/boot includes an outsole and a vamp, and a first opening is defined in the top of the shoe/boot. A first connection portion is located along the periphery of the first opening. A water-proof sock is inserted into the first opening and has a second opening defined in the top thereof A second connection portion is formed at the periphery of the second opening. The first connection portion is detachably connected to the second connection portion to secure the water-proof sock to the shoe/boot. The water-proof sock can be removed from the shoe/boot by separating the first connection portion from the second connection portion.

The soft boot and liner include a moisture transfer system that includes an inner fabric layer carefully selected from technically advanced fabrics. A series of layers are provided outside the inner liner including foam material layers, spacer fabrics and breathable membranes, in various orders. Encapsulation technology and waterproofing are used as well. The outer fabric layer is also capable of working with the other layers to promote the transfer of moisture. Frothed foams and flocking with fibers are further characteristics of the present invention. The moisture transfer system is incorporated into a soft boot or skate or as a removable liner for a shell boot. Numerous other modifications and applications are disclosed.

In at least some embodiments, an orthotic footbed assembly includes a three-dimensional footbed that closely approximates a size and configuration of a particular foot and at least one orthotic feature additively coupled to the three-dimensional footbed. In at least some other embodiments, a method of making the orthotic footbed assembly includes direct printing of orthotic features onto a 3-D footbed. Another method includes indirect printing of orthotic features and applying these features onto to a 3-D footbed. And yet another method includes direct printing of orthotic features onto a 2-D blank footbed and then conducting a three-dimensional forming operation to make the orthotic footbed assembly.
