A shoe part which has a one-piece molded shell with upper and lower open ends is disclosed. The shell includes a toe portion, a heel portion and two opposing side portions interconnecting the toe and heel portions. The lower open end has a flange which extends continuously along and projects inwardly from the lower open end and which has a looped edge to define an opening with a size smaller than the cross-section of the lower open end. The flange reinforces the lower open end, and the opening provides easy access to the inside of the shell for tooling. A boot which uses the shoe part as a lower is also disclosed. The boot is watertight at the seam of its lower and upper. |
