A welt is a strip of leather, rubber, or plastic that is stitched to the upper and insole of a shoe, as an attach-point for the sole. The space enclosed by the welt is then filled with cork or some other filler material (usually either porous or perforated, for breathability), and the outsole is both cemented and stitched to the welt. This process of making shoes is referred to as Goodyear welt construction, as the machinery used for the process was invented by the son of Charles Goodyear. Shoes with other types of construction may also have welts for finished appearance, but they generally serve little or no structural purpose. This article considers the process of shoe construction known as the "Goodyear welt". This process is the traditional method for the manufacture of mens dress shoes, taking its name from the inventor who devised the original hand sewn method. The benefit of a dress shoe which is made using the Goodyear welt construction is that the system allows for a constant flow of air through the shoe, which keeps the shoes ventilated, durable and strong.
