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.

A shoe is provided and includes a ventilated outsole that includes a recessed portion formed along an upper face of the outsole and has one or more openings formed along a ground contacting bottom face of the outsole. The shoe includes a ventilation insert disposed within the recessed portion. The ventilation insert includes a base layer that has through holes formed therein and a membrane that is coupled to the base layer. The base layer represents a bottom layer of the ventilation insert, while the membrane represents a top layer of the ventilation insert that are exposed over and cover the through holes formed in the base layer. The openings formed within the outsole are in communication with the recessed portion such that the ventilation insert is visible through the openings formed in the outsole.

Disclosed are a method for preparing a shoe shell and a twice-opening-mold shoe-making mold. The twice-opening-mold shoe-making mold comprises a machine table (1), a bottom mold (2) arranged on the machine table (1), an oil cylinder (3) arranged in the machine table (1) and connected to the bottom mold (2), and a mold main body (4) arranged above the bottom mold (2), wherein a mold cavity (21) is formed in an upper surface of the bottom mold (2). The twice-opening-mold shoe-making mold further comprises a mold inner core arranged in the mold main body (4), a mold inner edge (6) arranged below the mold inner core, an upper heating plate (7) arranged above the mold main body (4), a lower heating plate (8) arranged under the bottom mold (2), and a lifting mechanism (9) connected between the bottom mold (2) and the mold main body (4), wherein the mold inner edge (6) extends downwards from the interior of the mold main body (4) to a position below the mold main body (4) and is directly located above the bottom mold (2). A technology in the whole process is greatly simplified, thereby improving the working efficiency. Moreover, the shoe shell prepared by means of the twice-opening-mold shoe-making mold and obtained by using an integral forming technology is stronger and more durable compared with those obtained by means of a traditional shoe making technology.

Footwear (2) includes an upper assembly (4) having an outer construction (40, 42) and further having a bootie (50) made with a waterproof, breathable laminate, the waterproof, breathable laminate (51) including a one-piece functional layer (54) and at least one textile layer (56, 58), and a sole (6) attached to the upper assembly, wherein the bootie has elasticity in a circumferential direction of the bootie, wherein the bootie is fixed in position in a toe region (90) of the footwear and fixed in position in a heel region (96) of the footwear, and wherein the bootie is not attached to the outer construction on an upper side of a midfoot portion (92) of the bootie.

Aspects of the invention can be directed to a boot including a sole portion, a lower portion, and a boot shaft portion. The sole portion, the lower portion and the boot shaft portion can be formed as a unitary member composed of a single compound. The wherein the single compound can include: EVA in the range of 17% to 27%, POE in the range of 6% to 16%, SEBS in the range of 10% to 20%, and rubber in the range of 19% to 29%.

A waterproof and breathable upper comprises a fabric upper, a water-repellent structure, and a breathable waterproof film. The fabric upper has a first surface and a second surface, and the first surface is opposite to the second surface. The water-repellent structure is formed on the first surface of the fabric upper. The breathable waterproof film is formed on the second surface of the fabric upper.

A method for manufacturing a rubber boot having a foamed layer includes a first step of coating of boot-shaped lining sheath and a second step of rubber injection. A boot-sole-section coating layer, a boot-vamp-section coating layer, a boot-heel-section coating layer, and a boot-shaft-section coating layer that are coated on a boot-shaped lining sheath, after cured, provide a hardened surface and a stiff support structure among the coating layers that help melted rubber to efficiently flow and fill up runners inside a mold to thereby prevent defects from being formed in a rubber layer formed on a surface of a rubber boot so manufactured.

An insert for vapor-permeable and waterproof soles, which has a stratified and cohesive monolithic sheet-like structure, which includes a plurality of functional layers made of a polymeric material that is impermeable to water in the liquid state and permeable to water vapor. At least one functional portion of the insert for soles has such a thickness as to give it a penetration resistance of more than approximately 10 N, assessed according to the method presented in chapter 5.8.2 of the ISO 20344-2004 standard.

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.

The present invention provides a method for manufacturing a foam molded body, including: a setting step of inputting a foam matrix material into a mold that is not affected by microwaves, wherein the foam matrix material includes a plurality of half-foamed granules of thermoplastic polyurethanes (TPU) and at least an embedded component, and the embedded component is of a material or its product that is not affected by microwaves; and a foaming step of heating the mold by microwaves, wherein the half-foamed granules in the mold are affected by microwaves such that the temperature thereof are raised to effect foaming and the granules are squeezed with each other, and the embedded component is therefore squeezed and fixed, so as to form a foam molded body embedded with an embedded component after cooling and demolding.
