We wear technical, wind-blocking fabrics on our bodies, so why not on the temperature-sensitive feet? Assos thought the same thing, so they developed the Fugu Speer Socks S7. Facing the wind is Assos' RXQ fabric that flexes and stretches without bunching while providing superb insulation. The Fugus also boast Assos' breathable RX fabric and windproof toes for miles of pedaling comfort.
