3. When the pattern direction is 0 ° and 45 °, the friction coefficient between the soles is relatively high, and the anti slip performance is also good.

Rubber soles have the best slip resistance, while polyurethane soles have the worst slip resistance.
Rubber is commonly used in various sports shoes, while high-grade rubber is used in high-end leather shoes.
Advantages: Good wear resistance, anti slip, good softness and elasticity.
Disadvantage: Heavy weight.

Scientific analysis of misconceptions

Myth 1: Cow tendon bottom is the most anti slip
Many people often encounter this problem when buying shoes. The waiter often introduces shoes with cow tendon soles, which are good and slip resistant.
In fact, shoes with cow soles have the best wear resistance, but natural rubber soles are the most anti slip. This is because the cow tendon sole will gradually harden in cold winter and low temperature environments, thus affecting the anti slip effect of the sole. And natural rubber bottoms have better cold resistance than cow tendon bottoms, so they have the best slip resistance.

Myth 2: More patterns make it more slip resistant
Most people will feel that the more patterns on the sole, the more anti slip it becomes. Actually, this is not absolute.
Usually, softer materials have an increased actual contact area, resulting in higher friction and a relatively improved anti slip effect.
So the pattern on the sole does not necessarily have to be as deep as possible to prevent slipping. The material of the sole is soft and has good resilience, which is the best way for the sole to prevent slipping.
