X-BIONIC stockings dedicated off-road enduro motocross use. 14 ENGINEERING FEATS: THAT´S OUR OFF-ROAD PACKAGE. Even with the most comfortable motorcycle boots, the socks are the most important connection between man and machine. Only with the right socks can the comfort promised by a shoe or boot be guaranteed. When the foot sweats, the socks become a wet and cold bundle of fibres that even the best shoes can't save. That's why the X-SOCKS® Moto Enduro was designed to keep the foot dry and within the appropriate range of temperatures even on long rides. The different applications of climate-regulating materials offer the best that's available to meet the highest standards.
