The material of the sole (一)

1. OutsoleThe material of the outsole is simply natural rubber or synthetic rubber.

(1) Natural rubber: The advantage of natural rubber is that it is very soft, elastic and suitable for various sports, but the disadvantage is also obvious, that is, it is not wear-resistant. Indoor sports shoes mostly use natural rubber.

2. Synthetic rubber is divided into wear-resistant rubber, environmentally friendly rubber, air rubber, viscous rubber, hard rubber, and carbon 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, the main purpose of which is to protect the environment.

(3) Air rubber: The rubber contains air and has a certain shock-absorbing function, but it is not very wear-resistant and is not widely used.

(4) Sticky rubber: Sticky rubber is characterized by good flexibility and very non-slip, and is generally used in indoor sports shoes.

(5) Hard rubber: Hard rubber is the most comprehensive rubber in the outsole rubber material. It is tough, non-slip and wear-resistant, so it has a wide range of uses. Multifunctional shoes and basketball shoes mostly use this kind of rubber as the outsole.

(6) Carbon-added rubber: carbon is added to the ordinary rubber material to make the rubber more tough and wear-resistant. Most running shoes use this kind of rubber, and the letter BRS will be left on the back of the sole of the running shoe. Indicates that the outsole uses carbon-added rubber.

3. Glue outsole: This kind of outsole is not common. The raw material of this kind of bottom is industrial glue. It is stirred by a mixer, and then put into a mold for heating and forming. It is characterized by softness and very non-slip.
