Goodyear welt

A Goodyear welt is a strip of leather, rubber, or plastic that runs along the perimeter of a shoe outsole. The basic principle behind the Goodyear welt machine was invented in 1862 by August Destouy who designed a machine with a curved needle to stitch turned shoes. The machine was then improved in 1869 and later by Destouy and, more importantly, Daniel Mills, an English mechanic, both employed by Charles Goodyear Jr., the son of Charles Goodyear. It has been noted by historians that Goodyear was a frequent visitor to the shoe factory of William J. Dudley, founder of Johnston & Murphy, where early work on sole stitching equipment was performed.
