1.BRS 1000 carbon fiber rubber:
It is generally used to make rubber soles for Nike sports shoes. Carbon fiber material or carbon powder is added to rubber. This rubber outsole is more wear-resistant and has a good grip, but intense friction will leave black marks on the ground.
Two. Seamless rubber:
This is just the opposite of the manufacturing process of BRS 1000 carbon fiber rubber. Seamless rubber will not be mixed with carbon in the manufacturing process and will not leave traces on the floor. The grip is generally better than that of sports shoes without seamless rubber, and it is mostly used for Nike basketball shoes.
Solid rubber hard rubber:
Solid rubber hard rubber is compressed by 60% synthetic rubber and 40% natural rubber, which has good wear resistance and is the outsole material of most basketball shoes, and is suitable for outdoor combat.
Extended data:
The soles of sports shoes and travel shoes are flat-bottomed, with great plasticity and elasticity, which have a certain buffering effect on teenagers' running and jumping, so many teenagers like to wear them, but they also have many disadvantages after wearing them for a long time.
The materials used in travel shoes are mostly rubber, plastic, sponge, nylon, canvas and so on. Poor ventilation.
Sweaty feet are in this "closed" environment for a long time, which is easy to cause fungal reproduction and spread, and dermatoses such as beriberi, dermatitis and eczema appear.
Sports shoes or sports shoes are flat shoes without heels.
It can't ensure that the center of gravity of the human body is evenly distributed on the whole sole of the foot, and can't keep the muscles, ligaments, bones and spine of the body in normal positions and working conditions.
After teenagers put on sports shoes or sneakers, their body gravity changes and the stress distribution on their feet is uneven, which will affect their footwork. Wearing sports shoes for a long time is not only useless, but also very harmful to teenagers in their developmental stages.
