Compression socks are tight, especially at the bottom part. These are usually made of strong elastic and spandex. The strength of the elastic gets weaker as it goes up the leg. They are designed to put extra pressure on the feet, ankles, and calves. It became popular among runners, compression socks were initially worn by people who had blood vessel problems in the legs and had forced inactivity. Eventually, these became a prescription for people who had to sit for a long period of time, such as those who are traveling for long periods. Compression socks also help athletes ultimately improve their performance not only by promoting circulation but also by reducing recovery time and regulating temperature. Compression socks prevent and address problems associated with poor circulation in the legs. The compression helps fight the effects of gravity and assists the body in venous return, in which deoxygenated blood flows back up to your heart. This means preventing the blood from pooling in the lower legs can cause varicose veins and leg swelling. The main function of compression socks is to improve blood flow in your legs.
