Goodyear Welt
A strip of leather, the welt, is stitched to the upper and to a rib on the insole. The outsole is then stitched to the welt, never to the upper itself. That means a cobbler can cut the sole off and stitch on a new one, again and again. Named for Charles Goodyear Jr., son of the rubber pioneer, who mechanized the method.
