Flight socks or travel socks are worn to prevent blood clots (DVT) from forming when sitting in a confined space for a prolonged period of time, such as a long airplane flight. This is often referred to as Economy Class Syndrome. Travel socks should be tall enough to cover the calf muscle. A compression level of 15-20mmHg (moderate or firm) is advised.
A 2001 study of people on long haul flights found that 10% of the passengers that did not wear compression socks developed a DVT. The group that wore compression socks had none. Read more about traveler's thrombosis.
