The present invention is related to a water-resistant shoe and a method of making the water-resistant shoe. In most embodiments the shoe comprises an outsole, an insole, an upper, and a bootie product comprised of a bootie, a bootie liner, a strobel and a gasket. In many embodiments water-resistant materials such as tape or glue are used to cover all seams and joints. In some embodiments the different pieces are tested for water-resistance before combining and in others the final shoe is tested for water-resistance. The present shoe and method provide a comfortable yet water-resistant shoe.

A footwear includes an upper and a sole. The upper includes a membrane and at least one outer layer. The membrane is a waterproof and breathable membrane. The membrane is attached to an insole and the membrane is attached to a lower end of the outer layer. The membrane is adhered to the lower end of the outer layer by an anchoring adhesive. The anchoring adhesive is resistant to post treatment and the insole is attached to the sole.

Composite materials are described herein. An example composite material may comprise a shell fiber layer. The example composite material may comprise a membrane disposed adjacent the shell fiber layer.

A moisture-permeable waterproof shoe includes an upper unit, an inner sleeve unit, and an outsole unit. The upper unit defines an inner space having a top open end and a bottom closed end. The inner sleeve unit is fixedly disposed in the inner space, and includes a moisture-permeable waterproof shoe-like inner sleeve and a thermoplastic polyurethane (TPU) sheet. The moisture-permeable waterproof shoe-like inner sleeve has an inner sleeve bottom surface and defines a wearing space having a top open end and a bottom closed end. The TPU sheet has a top surface fixedly connected to the inner sleeve bottom surface by a high-frequency welding method. The outsole unit is fixedly connected to an underside of the upper unit.

A boot comprises: an outsole and a polymeric upper affixed to the outsole. The upper comprises an upper body and a gusset, which comprises a relaxed position and an expanded position, wherein the gusset moves from the relaxed position to the expanded position to accommodate a wearer's leg upon donning of the boot.

The present invention relates to a flexible waterproofing/impregnation and drying de-vice and a method of drying items that have undergone a solvent-based or water-based waterproofing/impregnation process. The flexible waterproofing/impregnation and dry-ing device is configured with inlets for waterproofing/impregnation fluid for water-proofing/impregnating items and one or more heat generating units for effective drying of items, said items being for example clothes, shoes, bags, purses, blankets and garments.

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.

A method for preparing a shoe shell using a twice-opening-mold shoe-making mold comprises steps of preparing rubber for the shoe shell and cutting the rubber for the shoe shell into elongated or square sizes; heating the twice-opening-mold shoe-making mold to required temperatures within 3 hour; and opening the twice-opening-mold shoe-making mold with the bottom mold of the twice-opening-mold shoe-making mold being opened in a direction away from the mold main body of the twice-opening-mold shoe-making mold; putting the rubber for the shoe shell into the twice-opening-mold shoe-making mold; closing the bottom mold towards the mold main body, lifting the mold inner edge of the twice-opening-mold shoe-making mold to be stored into the mold main body until the bottom mold and the mold main body are closed, and performing a heating for 2-8 minutes; separating the bottom mold from the mold main body periodically during heating; reopening the twice-opening-mold shoe-making mold; taking out a semi-finished shoe shell; and trimming the semi-finished shoe shell.
