The foot of the boot is of conventional construction but the shaft of the boot is made of thermoplastic sheet which is stretched on a form and heated to shape the shaft. After stitching of the cut thermoplastic sheet to the leather upper, a last piece 18 is inserted in the toe and a split boot-tree consisting of parts 16 and 17 is placed in the shaft. A slider 20 running in a groove in part 17 has wedges 21 which engage cam blocks 22 and force parts 16 and 17 apart to stretch the shaft while it is heated. Alternatively, the shaft may be shaped before being attached to the rest of the boot. <IMAGE> |
