Some people are frugal in life. They don't want to wear shoes for many years.

Zhao Chan, a shoe salesman in Tianjin, suggested that if shoes had started skidding and did not follow their feet, a new pair of shoes should be replaced in time, or there would be safety risks.

The location is generally divided into three parts: the former, the latter and the latter.

The front foot and heel part will have a texture, which will help to increase friction during walking.

The middle part supports the arch, and it will bend repeatedly when walking.

The patterns of the forefoot and heel are getting lighter and even slippery, and the "slope" caused by the wear of the heel and inside and outside sides is getting bigger and bigger, which makes it easy for people to slip and sprain when they walk.

The middle part of the soles will gradually crack with the use of shoes. If not observed in time, there will be danger in the sudden rupture.

In such cases, shoes should be replaced in time for walking safety and foot health considerations.
