What's the difference between rubber outsole and rubber sole?

1, different additives in the production process.

The materials of the outsole are generally synthetic rubber and reinforcing agent. Rubber soles can be made of natural rubber or synthetic rubber without additives.

2. Different advantages

Rubber soles have high elasticity and wear resistance, and can withstand repeated bending, stretching and compression without damage, thus improving comfort and reaction speed. It also has the characteristics of acid and alkali resistance, and is suitable for wearing in rainy days. The rubber outsole is more wear-resistant than ordinary rubber soles, mainly because additives are added.

Extended data

Synthetic rubber sole: Synthetic rubber is divided into wear rubber, environmental protection rubber, gas rubber, viscose, hard rubber and carbon rubber.

1, wear rubber: wear rubber is very durable because of its excellent wear resistance and toughness. This rubber material is generally used on the outsole of tennis shoes.

2, environmental protection rubber: also known as reclaimed rubber, this rubber outsole contains reclaimed rubber as high as 10%, the main purpose is to protect the environment.

3, air rubber: rubber contains air, which has a certain damping effect, but it is not very wear-resistant and not widely used.

4. Velcro tape: Velcro tape is characterized by good flexibility and very non-slip, and is generally used for indoor sports shoes.

5. Hard rubber: Hard rubber is the most comprehensive rubber in outsole rubber materials. It is tough, non-slip, wear-resistant, and has a wide range of natural uses. Multifunctional shoes and basketball shoes mostly use this rubber as soles.

6. Carbonized rubber: carbon is added to ordinary rubber materials to make rubber more tough and wear-resistant. Most running shoes use this kind of rubber, and the letters BRS will be left on the back of the sole of running shoes, indicating that the outsole is made of carbon rubber.
