Rubber sole materials can be roughly divided into natural rubber or synthetic rubber.
The advantage of natural rubber is that it is very soft and elastic, and can be adapted to various sports. However, the disadvantage is also obvious that it is not very wear-resistant. Indoor sports shoes mostly use natural rubber.
Synthetic rubber is divided into wear-resistant rubber, environmentally friendly rubber, air rubber, sticky rubber, hard rubber, and carbon-added rubber.
(1) Wear-resistant rubber: Wear-resistant rubber has very good wear resistance and toughness, so it is very durable. This rubber material is generally used on the outsole of tennis shoes.
(2) Environmentally friendly rubber: Also known as recycled rubber, this rubber outsole contains up to 10% recycled rubber, and its main purpose is to protect the environment.
(3) Air rubber: Rubber contains air and has a certain shock-absorbing function, but it is not very wear-resistant and is not very widely used.
(4) Sticky rubber: Sticky rubber is characterized by good flexibility and very anti-slip. It is generally used in indoor sports shoes.
(5) Hard rubber: Hard rubber is the most comprehensive rubber material among outsole rubber materials. It is tough, non-slip and very wear-resistant, so it has a wide range of uses. Most multi-functional shoes and basketball shoes use this kind of rubber as the outsole.
(6) Carbon-added rubber: Carbon elements are added to ordinary rubber materials to make the rubber more tough and wear-resistant. Most running shoes use this kind of rubber, and the letters BRS are left on the back soles of the running shoes to indicate Indicates that the outsole uses carbon-added rubber.
