Lewis N. Clark Flight Socks provide graduated leg compression and support to improve blood circulation, prevent tired, swollen legs on long journeys, and aid in the prevention of Deep Vein Thrombosis (DVT).
DVT is a condition in which a blood clot forms in a vein that is deep inside the body, and mainly affects the large veins in the lower leg and thigh.
