What is the purpose of a Goodyear welt in shoe construction?

The purpose of a Goodyear welt in shoe construction is to hold the insole and outsole together. This method involves a strip of leather that is stitched to both the upper part of the shoe and the outsole, creating a durable bond that enhances the shoe's structure and longevity. The Goodyear welt allows for the shoes to be easily resoled, making them a preferred choice for high-quality footwear. By securing the components of the shoe together, it aids in maintaining its shape and providing a stable foundation for the wearer's foot.

In contrast, while decorative style can be a byproduct of the craftsmanship seen in Goodyear welted shoes, that is not its primary purpose. Similarly, cushioning is not a direct function of the welt itself, as it pertains more to the materials used within the shoe. Protecting the toes is also not relevant to the purpose of a Goodyear welt; this function is typically addressed by the shoe's construction and design, rather than the welting technique.
