Synthetic soles are shoe components made from man-made materials, such as rubber, polyurethane, or EVA (ethylene-vinyl acetate). These materials are designed to provide durability, flexibility, and comfort, making them popular in various types of footwear, including athletic shoes and casual wear. Unlike natural materials like leather, synthetic soles are often more resistant to water and wear, which can enhance the longevity of the shoes. Additionally, they can be produced in various colors and styles, allowing for greater design versatility in brands like Nike and Adidas.
