Goodyear Welt is a shoe construction technique used in the manufacturing of footwear with stitched soles. This construction method uses a narrow strip of leather called welt which is first sewn to the upper and inner sole of the shoe, then stitched to the outsole creating a stronger bond between the parts. Goodyear Welt construction allows multiple sole replacements as well as better air flow through the shoe.
About Heels:
Heels are shoes featuring an incline on the heel. Heels could be a separate piece from the outsole or a wedge heel that runs the entire length of the outsole. The heel provides elevation and can be found in many different shapes, including block, tapered, blade, and wedge. Heels can also be many different heights such as Kitten Heel, Stilleto Heel, Low Heel, Mid Heel or High Heel.
