Rubber soles are the bottom part of footwear made from rubber, a flexible and durable material. They provide traction, cushioning, and protection for the feet. Rubber soles are commonly found in various types of shoes, including sneakers, boots, and sandals, making them popular for both casual and athletic wear. The use of rubber soles enhances comfort and stability while walking or running. They are also water-resistant, which helps keep feet dry in wet conditions. Many brands, such as Nike and Adidas, incorporate rubber soles in their designs to improve performance and longevity of their products.
