<unk> <unk>  (Flight Socks, Support Bandage) are a specialized hosiery designed to help prevent the occurrence of, and guard against further progression of, venous disorders such as edema, phlebitis and thrombosis.<unk>  are elastic compression garments worn around the leg, compressing the limb. This reduces the diameter of distended veins and increases venous blood flow velocity and valve effectiveness. Compression therapy helps decrease venous pressure, prevents venous stasis and impairments of venous walls, and relieves heavy and aching legs. Knee-high<unk>  are used not only to help increase circulation, but also to help prevent the formation of blood clots in the lower legs. They also aid in the treatment of ulcers of the lower legs. Unlike traditional dress or athletic<unk>  and socks,<unk>  use stronger elastics to create significant pressure on the legs, ankles and feet.<unk>  are tightest at the ankles and gradually become less constrictive toward the knees and thighs. By compressing the surface veins, arteries and muscles, they force circulating blood through narrower channels. As a result, the arterial pressure is increased, which causes more blood to return to the heart and less blood to pool in the feet. There are two types of<unk> , gradient and anti-embolism.<unk>
