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.
