<p>A shoe construction having a sole with an outsole shell (20) that is filled with a filling material (24), such as polyurethane foam, and secured to the upper (12) by a welt (16). The sole includes an insole (18) having a downwardly extending rib (44), an outer shell (20) defining a void (22) containing the filling material (24), and a welt (16) that interconnects the outsole shell (20) and the insole (18) with the upper (12). To assemble the construction, the upper (12) is lasted and either stitched or stapled to the insole (18). The welt (16) is then stitched or stapled to the insole/upper combination. Next, the filling material (24) is poured into the void (22) in the outsole shell (20) and the shell is directly attached by the filling material (24) to the upper/insole/welt assembly. The welt (16) is stitched to the outsole shell (20) around the entire periphery of the sole. The stitch extends between a stitch groove (38) in the welt and a stitch groove (58) in the outsole shell. The use of the outsole shell (20) and the filling material (22) produces a sole construction which is lightweight and flexible and suited to a welted construction. <IMAGE></p> |
