A waterproof shoe includes a hollow sole pad having an intermediate opening, an inner marginal end confining the opening, an outer marginal portion spaced from and extending around the inner marginal end, and an upstanding flange which projects from the sole pad between the outer marginal portion and the inner marginal end and which loops around the opening . An upper has a bottom open end stitched to one of the outer marginal portion and the upstanding flange. A lining sleeve is disposed inside the upper and is made of a material which is impervious to water but is pervious to vapors. The lining sleeve has a bottom open end stitched to the upstanding flange of the sole pad to form a stitch seam which is then sealed by means of waterproof means. The bottomless lining sleeve and the hollow sole pad permits the lining sleeve to be secured and sealed watertight to the sole pad in a less complicated manner. Drainage is permitted at the stitch seam of the sole pad and the upper.
