A waterproof foot covering has a breathable upper enclosure of an upper, a waterproof inner lining sleeve to line the upper enclosure, and a waterproof lower enclosing shell of a lower. The bottom open end of the upper enclosure, the bottom open end of the inner lining sleeve and the upper open end of the lower enclosing shell are interconnected together by sewing, thereby forming a stitched seam. A waterproof seam-sealing member is disposed inwardly of the stitched seam. The seam-sealing member is attached to the inner surfaces of the inner lining sleeve and the lower enclosing shell, whereby water-permeation through the stitched seam from a location between the inner lining sleeve and the upper enclosure to the exterior of the upper enclosure is permitted while water-permeation through the stitched seam to the interior of the inner lining sleeve and the lower enclosing shell is prevented. A method for providing the seam sealing member to the stitched seam of the upper enclosure, the inner lining sleeve and the lower enclosing shell is also disclosed.
