Made with medical grade compression material, the Assos Kompressor Socks are the ultimate breathable racing sock. Using the same innovative design and compressive 25mmHg InfraRed yarns as the Assos recovery socks, these bad boys promote blood flow while riding, not just recovering. An ultrasoft 240-needle construction increases mobility and softness, eliminating friction during those long, sweaty rides. You'll stay at the front of the peloton in plush comfort while wearing the Assos Kompressor Socks.
