Get smart support for optimal performance on long runs with the X-SOCKS® TRAIL RUN ENERGY.
With over 10 patented technologies, the high-tech X-BIONIC® 4.0 generation trail run sock offers optimal comfort. Three high-performance yarns are tightly knitted in the innovatively processed material: The particularly soft and climate-active yarn Skin NODOR® keeps your feet hygienically fresh. The lightweight yarn Mythlan® stops germs and odors. Bisentio®, the multifunctional hollow fiber, is breathable, absorbs shocks and is extremely durable. 
Thanks to the Albedo® 360-degree reflective yarn on the outer cuff, safety in the dark is also increased. The dense material structure encloses the shape-optimized Air-Conditioning Channel® 4.0, which provides ventilation for the sole of the foot. Above the heel, the Lambertz-Nicholson Achilles Tendon Protector® 4.0 with its newly dimensioned pads protects against pressure and friction.
