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.

Hard rubber is the most comprehensive rubber among the rubber materials of the outsole. It is tough, anti-slip and wear-resistant. It is naturally widely used. Multi-functional shoes and basketball shoes are mostly made of this rubber outsole.
