Vitalizer compression socks are specifically constructed to the contour lines of the left and right foot, resulting in an anatomically perfect fit. With excellent moisture-wicking properties, not only are they ideal for running and cycling, they are too great for travelling and other exercises. In addition, three compression zones are located on this sock: above the ankle, below the calf, and on the calf, which prevents lactic acid build-up by promoting oxygenated blood cells in the leg - aiding recovery and enhancing performance.
