Rubber sole refers to the sole made of rubber. The rubber sole material can be roughly divided into natural rubber or synthetic rubber. The advantage of natural rubber is that it is very soft, has excellent elasticity, can adapt to all kinds of sports, and plays a role in shock absorption, but the disadvantage is also very obvious that it is poor in oil resistance, ozone aging resistance and heat and oxygen aging resistance. Indoor sports shoes are mostly made of natural rubber.

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.
