Abstract
A shoe includes an upper shell, a lining sleeve lining the upper shell, a sole, and a lower shell disposed between the sole and the upper shell. The lower shell consists of at least one waterproof strap which is made of a waterproof material and which has a bottom margin connected to the sole, and a top margin to connect with the upper shell and the lining sleeve. The top margin is bifurcated to form an upwardly extending water draining part and an upwardly extending sealing part. The sealing part extends inwardly of the water draining part and has a height approximately equal to or greater than that of the water draining part. The water draining part extends inwardly of and is sewn to the bottom open ends of said upper shell and said lining sleeve, thus forming a stitch joint. The sealing part is sealingly bonded to the stitch joint.
