Compression or support socks are designed to increase your blood flow and provide support. The purpose of compression socks is to provide graduated pressure to your lower leg and foot. The graduated pressure forces the surface veins to narrow and arterial pressure to increase, causing less blood to pool in the feet. Instead, the blood returns to the heart, as it is supposed to.
Compression socks use rubber or spandex to create the pressure on the foot, ankle, and legs. Compression socks are just not for people with circulation issues. Experts suggest that travelers, athletes, and even people who spend a lot of time standing will benefit from wearing compression socks.
