This is a big mistake. Generally speaking, a fitness person should prepare at least two pairs of multifunctional sports shoes or jogging shoes, and replace them once a week. Taking into account the seasonal factors, if the temperature difference between the places of residence is large, two pairs should be prepared in winter and summer. If children like sports, they should consider adding a pair of special sports shoes, such as basketball shoes, football shoes, etc.

The functional nature of sports shoes determines that it should be changed regularly.

Although some shoes look very bright, they may not be able to provide enough support and shock absorption after the expiration date.

As for whether sports shoes are out of date, we can judge from the following three points: first, look at the sole of shoes; if the heel has a clear radian, and the shoe pattern or logo has been blurred, then we should not hesitate to replace it; secondly, look at the shoe type, if the shoes are too upwards, or the heel is falling down from the inside, it should also be replaced; finally, if you wear a pair of sports shoes for a while, feel that the ankle, knee or waist are uncomfortable or even painful, which means that these shoes are not suitable for you. Conversely, if a pair of shoes has been twisted with your feet, it should be replaced.

What should arouse the attention of the majority of parents is that teenagers only wear sneakers and it is not a good idea, and a pair of sports shoes can not cope with all situations.

Wearing sports shoes for a long time brings many problems: because of the high temperature and humidity in the shoes, the foot ligaments are elongated and loosened, and the feet become wider and even flat. Moreover, because of the reasons of materials, some shoes have poor air permeability. For a long time, under the "closed" environment, fungi can propagate and spread, develop tinea pedis, dermatitis, eczema and so on. Finally, no flat bottomed sports shoes can keep the muscles, ligaments, bones and spine of the body in a normal position. Teenagers are wearing clothes for a long time and are not good for growth and development.

In addition, do not wear too many special sports shoes in daily life, their hard fixed upper and even thickness sole, although it is good for the rotation of the feet and sudden movement, but not conducive to daily activities; conversely, wearing running shoes in basketball, tennis and other ball games will also increase the risk of sprain because of inadequate ankle support or insufficient friction.
