2, TPR sole: the skid resistance is not as good as PU, but it is more resistant to operation than PU's sole, and there will be no low-temperature edge breakage like PU.
3, leather outsole: the anti-slip effect is also relatively slag, compared with the sole of TPR, its only advantage is high-grade.
4, foam outsole: the anti-slip effect is better than PU and TPR, and it is hard.
5, rubber outsole: anti-slip effect is already a better material, the disadvantage is heavy.
6. Raw rubber outsole: the chemical protection effect is perfect, but the pattern and thickness are relatively small, and the material is special, which will harden when it is cold.

How to make the sole slip-proof?
1. Rub the soles with sandpaper.
The main purpose of sandpaper grinding is to make the sole not smooth, which can increase the friction between the sole and the ground and achieve the effect of anti-skid. This method is simple and quick, and sandpaper is relatively easy to obtain.
Step 2 wipe the soles with raw potatoes
Because raw potatoes contain a lot of starch, if you wipe the soles with raw potatoes, the starch on the potatoes will stay on the soles after the water dries, thus achieving the anti-slip effect. This method will consume potatoes, and the anti-skid effect is relatively general.
3. Tape sticking method
This principle is also used to increase the friction between the sole and the ground, especially in rainy days. This method is simple and economical. If the tape is sticky enough, it can be used many times at a time. The anti-skid effect is also very good, but the bottom is a little ugly, but others can't see the sole.
4, the method of cutting the sole with a knife
The principle of this method is well known, and it is also a way to increase friction. The advantage of this method is good anti-skid performance, which is much better than the first and second methods. The disadvantage is that the shoes are more damaged. It is generally not recommended unless you only want to use this shoe for a period of time.
