Compression socks are specialized hosiery items designed to provide extra support and increase blood circulation. Compression socks are not to be confused with traditional dress socks or non-compression diabetic socks, although they may look similar. The main purpose of compression socks is to provide graduated pressure on the lower leg and foot. Experts suggest passengers on long flights should wear compression socks to prevent circulatory problems like deep vein thrombosis, leg cramps and edema. Athletes often wear compression socks to give their leg muscles additional support while running or jumping. Those with occupations requiring long periods of standing may also benefit from the use of compression socks.
