Socks play an important role in our daliy life. Apart from keeping feet warm, socks also have many advantages.

First of all, socks can be used as a physical barrier to separate the feet from the microorganisms in the shoes, so as to avoid inducing diseases such as athlete`s foot.

Secondly, socks can reduce the friction between the skin of feet and shoes, thus preventing blisters and scratches, and can also prevent [cocoons" and [corns" on feet due to skin keratosis. If you are allergic to rubber, leather and other shoe materials, socks can also avoid contact and friction between feet and shoes, thus reducing the risk of contact dermatitis.

Moreover, socks can avoid many diseases caused by coldness on the soles of feet. Because the fat layer on the bottom of the foot is thin, the ability to resist cold is poor, and it is easy to get cold. Once the soles of the feet get cold, the capillaries in the mucous membrane of the upper respiratory tract will contract reflexively, significantly reducing the body`s resistance, and the bacteria and viruses originally lurking in the nasopharynx will take the opportunity to enter, and then cause many diseases such as colds.
