Synthetic rubber is also divided into wear-resistant rubber, environmental rubber, air rubber, viscous rubber, hard rubber and carbon rubber. Wear-resistant rubber has excellent wear resistance and toughness, so it is very durable. This rubber material is generally used on the soles of tennis shoes. Also known as recycled rubber, this rubber outsole contains up to 10% recycled rubber, mainly for environmental protection.

The rubber contains air and has a certain shock absorption function, but it is not very wear-resistant and has not been widely used. Sticky rubber is characterized by good flexibility and very anti-slip. It is generally used on indoor sports shoes.
