Sparco fireproof compression socks. These calf length socks are designed to combat the build up of lactic acid in your lower legs and in turn aleviate cramp within your calf muscles. The socks have an 80% Nomex, 20% Viscose and 10% Elastane composition and are probably the most advance fireproof socks currently available. Ideally suited to longer endurance events, rallying, desert raids etc.
