Vitalsox, Sox, Travelsox, Worksox, and Caresox products are made to incorporate the latest technologies: How Compression Socks Work: Compression socks exert gentle pressure one the legs, reducing the diameter of distended veins, and causing an increase in blood flow throughout the body. Unlike traditional dress or athletic socks, compression socks use stronger elastics to create pressure on the legs, ankles and feet. By compressing the surface veins, arteries and muscles, the circulating blood is forced through narrower circulatory 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. The result is relief from tired, heavy legs.
