One. Tooth type of sole. Thick transverse tooth patterns are more slippery than thin longitudinal tooth patterns.
Two. Sole material. Mainly the bottom material that contacts the ground.
If it is flat shoes or wedge shoes, the rubber sole has the best ability to prevent dry sliding and waterproof sliding. The purer the rubber composition, the better. For example, we often say "beef tendon" refers to yellow translucent high-purity rubber (raw rubber).
Of course, purity has nothing to do with color. The simplest way to tell is to smell it. Rubber soles containing many impurities have a pungent sour taste. (It should be pointed out that not all yellow translucent materials are rubber, and PVC and TPR materials can also be made into that shape. ) So the best way is to smell it. Raw rubber has a rubbery taste and is not irritating.
In addition, the drought-resistant and anti-skid ability of PU material is also good, which has the advantage of portability. But PU is not waterproof and antiskid like rubber. If it is high heels, you also need to pay attention to the material of the heel surface. Materials that are easy to grind white burrs have poor anti-skid performance.
Extended data:
The material of outsole is simply natural rubber or synthetic rubber.
Natural rubber: the advantage of natural rubber is that it is very soft and elastic, and it can be suitable for all kinds of sports, but the disadvantage is also obvious, that is, it is not wear-resistant. Indoor sports shoes mostly use natural rubber.
Synthetic rubber is divided into wear rubber, environmental protection rubber, inflatable rubber, viscous rubber, hard rubber and carbon rubber.
Wear rubber (1): wear rubber has excellent wear resistance and toughness and is very durable. This rubber material is generally used on the outsole of tennis shoes.
(2) Environmentally friendly rubber: Also known as reclaimed rubber, this rubber outsole contains reclaimed rubber as high as 10%, mainly for environmental protection.
(3) Air rubber: Rubber contains air, which has a certain damping effect, but it is not very wear-resistant and has not been widely used.
(4) Viscous rubber: Viscous rubber is characterized by good flexibility and very anti-slip, and is generally used for indoor sports shoes.
(5) Hard rubber: Hard rubber is the most comprehensive rubber in the outsole rubber material, which is tough, non-slip and wear-resistant, and has a wide range of natural uses. Multifunctional shoes and basketball shoes mostly use this rubber as soles.
