In outdoor sports, some people think that as long as the socks are thick, at least two pairs of cotton socks can be used to protect the feet. This is reasonable, because the two pairs of socks can be better attached. Attached to the foot, it weakens the friction between the foot and the sock and translates into friction between the sock and the shoe.
However, in this way, another problem has been neglected. After a long walk, the feet will expand by 7%-8%. The two pairs of socks will be hung on the whole foot, even above the ankle. The part is also included, resulting in poor blood circulation in the feet, which can cause some foot diseases. In winter or in extremely cold areas, unnecessary frostbite is caused.
