Sole types refer to the different designs and materials used for the bottom part of footwear. Common types include rubber soles, known for their durability and grip, and leather soles, which offer a classic look but may not provide as much traction. Other variations include foam soles, which are lightweight and cushioned, and vibram soles, recognized for their high-performance traction in outdoor activities. Each sole type serves specific purposes based on the intended use of the shoe. For instance, athletic shoes often feature rubber or foam soles for comfort and support during physical activities, while dress shoes may utilize leather soles for a polished appearance. Understanding sole types can help consumers choose the right footwear for their needs.
