Myth 1: The bottom of tendon is the most slippery.
Many people buy shoes, and waiters will introduce them. It's a tendon-soled shoe, so it's non-slip.
Li Rongjiu said that in fact, shoes with tendon soles have the best wear resistance, but natural rubber soles are the most non-slip. This is because in the cold winter and low temperature environment, the tendon bottom will gradually harden, thus affecting the anti-slip effect of the sole. The cold resistance of natural rubber soles is better than that of beef tendon soles, so the skid resistance is the best.
Myth 2: The more patterns, the more slippery.
Everyone thinks that the more patterns on the soles, the smoother they are. In fact, this is not absolute.
Teacher Guo, who teaches physics in a school in Changchun, said that through experiments, it can be seen that the greater the friction of soles, the shorter the sliding distance, and the better the skid resistance of shoes. The larger the actual contact area with the ground, the greater the friction. Due to the different hardness of the sole material, the instantaneous deformation of the material is also different, so its actual contact area is also different. Usually, the actual contact area of softer materials will increase, so the friction will be higher and the anti-skid effect will be relatively improved.
The pattern of the sole can effectively increase the contact area between the shoe and the road surface. On some gravel, dirt, lawn and other roads, the convex lines of the sole can penetrate deep into the soft road, so that the vertical part of the convex lines also becomes the part in contact with the ground, thus greatly increasing the friction force. On the street or even on the tile floor, the floor is very hard, and the pattern of the sole makes the contact area between shoes and the floor smaller, and the friction force is also obviously reduced. Therefore, the pattern of the sole does not have to be as much as possible, and the deeper it is, the more slippery it is. The sole material is soft, elastic and non-slip.
In addition, the different hardness of the sole has different effects on the deformation of the sole. For soft soles, the contact area can be increased to increase the friction, while for hard soles, such deformation is very small, so the friction of shoes with soft soles on hard roads is definitely greater than that of shoes with hard soles. Therefore, shoes with soft soles have better anti-skid effect than shoes with hard soles.
There is a coup at home.
You can also make your own non-slip shoes.
Now that we know which sole has better anti-skid performance, how can we make our sole more anti-skid? It's a bit unrealistic to change a pair of shoes with rubber soles. Introduce two small methods and try them:
Method 1: Stick electrical tape.
Operation method: Cut off two pieces of electrical tape and stick them on the front end of the sole and the heel respectively, and trim the edge, and a non-slip shoe will be finished.
Method 2: Stick a non-slip pad.
How to operate: In families with children, children will run around in shoes because the floor is too slippery and often fall down. Mothers can go to the supermarket to buy anti-slip mats on the table, then cut them into the shape of baby shoes and stick them on the soles. It can also be adhered to the soles of adults. Although it doesn't look very beautiful, it can increase the friction of shoes and play an anti-slip role.
