1. Rub the soles with sandpaper. The main principle is to rub the soles not smooth and increase the friction between the soles and the ground.
2. Rub the soles with raw potatoes. The main principle is that raw potatoes are rich in starch, and rubbing the soles with raw potatoes leaves the starch in the soles to achieve an anti-slip effect.
3. The main principle of the tape method is actually to increase the friction between the sole and the ground.
4. Use a knife to scratch the soles. The advantage of this method is that it has very good anti-slip properties and is much better than the first and second methods. But his shortcoming is also obvious, that is, he damages the shoes to a large extent. :
Whether the soles are anti-slip is related to two factors:
1. The tooth pattern of the soles. Generally speaking, coarse transverse teeth are more slip-resistant than fine longitudinal teeth.
2. Sole material. Mainly the material of the bottom surface that touches the ground. If it is a flat-soled or wedge-heeled shoe, the rubber sole has the best anti-slip and waterproof capabilities.
