Take the intelligent shortcut to the future of running with the X-SOCKS® RUN FAST 4.0! Thanks to patented technologies, you can effortlessly reach your goal.
This special sock with barefoot climate benefits from the latest innovations in X-SOCKS® technology and offers you incomparable wearing comfort. More support, secure protection and continuous thermoregulation promote your performance and endurance. Your foot gets a firm hold in the anatomically shaped footbed and the ASYMMETRIC O-RING BANDAGE stabilizes your ankle joint. Protectors keep the toes, heel and ankle from being injured by pressure and friction.
The optimized Air-Conditioning Channel® 4.0 delivers fresh air into the shoe every step of the way, stopping moisture and reducing the risk of blistering. The newly designed Lambertz-Nicholson Achilles Tendon Protector 4.0 protects the sensitive area above the heel. Reinforced, two-part padded zones absorb pressure, friction and shocks even more effectively.
Albedo® 360° Reflective Technology increases safety in the dark.
