Abstract: 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.
Abstract: A process for manufacturing a waterproof and vapor-permeable shoe is provided. In the process, an adhesive layer is provided on a knitted fabric to form a laminate, and a shoe upper unit is formed from the laminate, and has an adhesive component defining an inner space of the shoe upper unit. A shoe lining member, which is worn on a last, is placed into the shoe upper unit to permit a knitted component of the shoe upper unit to be bonded to the shoe lining member through the adhesive component under a heating treatment.
