The Goodyear welt is a method of shoe construction that enhances durability and comfort. It involves stitching a leather strip, known as the welt, to the upper part of the shoe and the insole. This creates a cavity where the outsole can be attached, allowing for easy resoling and extending the shoe's lifespan. This technique was developed by Charles Goodyear in the 19th century and is often associated with high-quality footwear. Shoes made with the Goodyear welt are typically more water-resistant and provide better support, making them a popular choice for both casual and formal styles.
