A rubber sole is a type of shoe sole made from natural or synthetic rubber. It refers to any footwear that has been manufactured with a layer of rubber material on its base, providing cushioning and traction for the wearer's feet while walking, running, or engaging in other physical activities. Rubber soles are commonly used in various types of shoes such as sneakers, sandals, boots, and even dress shoes to enhance durability, comfort, and grip on different surfaces.
