The Sky Run from X-Socks is the ideal sock for marathon runners and joggers. It is especially lightweight and breathable, thanks to the AirGoTex mesh cuff. The integrated X-Cross Bandage and the AirFlow Design Ankle Pads protect the sensitive ankle region. The AirConditioning Channel ensures a steady supply of fresh air all the way down to the sole of the foot. The 99.9%-pure silver in the Sinofit footbed works actively to prevent the growth of bacteria and germs and reduces the risk of developing athlete's foot. Also Available in Black.
