The PUMA by X-BIONIC® Run Performance socks keep your feet going with enhanced technology. Cushioning zones are placed on the most anatomically vital areas to reduce the risk of pressure points and abrasions—even during peak endurance. Your feet have constant ventilation and stay airconditioned by natural means through the breathability of the newly-developed materials and mesh-knitting techniques used in the ventilation zones. In these socks, every performance detail matters.
