Abstract: A shoe body of a waterproof boot includes a vamp having a first opening formed with a first combination plate and a second opening formed with a second combination plate, a cloth strip rested on the inner side of the second combination plate and having a first elongated side and a second elongated side, and a stitching line sewn in the stitching groove of the second combination plate, for sewing and fixing the first elongated side of the cloth strip on the inner side of the second combination plate. Thus, by arrangement of the cloth strip, the stretcher may be used to position the inner side of the vamp on the surface of the shoe tree closely and completely, thereby obtaining the optimal size and configuration to fit the requirements of the waterproof boot.
