In 1872, Charles Goodyear invented a machine capable of producing an easily replaceable, high-wear shoe. This marked a revolution in the footwear market, so much so that the sewing method adopted his surname - Goodyear.
Goodyear welts are the most time consuming but most durable method of making shoes. This can be done by hand or by machine, however, both options require highly specialized craftsmen. After more than 120 steps, it takes up to 4 days to manufacture a pair of shoes.
the Goodyear shoe was worth the wait, as one of its many strengths is its ability to stand the test of time. The leather allows the foot to breathe, and the cork insole adds extra comfort as it molds to your step. Furthermore, the entire process is characterized by overlapping structural elements that will provide unrivaled resistance.
Finally, attach the piece of leather that will serve as the sole.
The sole will be sewn onto the welt and will be the base on which to place the heel. At this stage, the sole has been sewn twice. The first joins the upper with the welt, and the second stitch joins the welt to the leather sole. This dual attachment will allow for an easier resole process since the welt acts as a shock absorber between the insole and outsole and can be done without special machinery.
This will extend the life of the shoe to decades if the shoe follows a regular shoe care routine. Additional stitching between the outsole and upper will provide the foot with a higher level of waterproofing and protection.
