Unlock your full potential and let the perfect functionality of the X-SOCKS® TRAIL RUN ENERGY WOMEN accompany you on your journey to maximum performance. With more than ten patented technologies, this high-tech trail running sock of the X-BIONIC 4.0 generation offers optimal comfort for women's feet. Three high-performance yarns are tightly woven into the innovative material: the particularly soft and climate-active Skin NODOR® yarn keeps the feet hygienically fresh, the lightweight Mythlan® yarn combats germs and odors, and Bisentio®, the multifunctional hollow fiber, is breathable, shock-absorbing, and extremely durable. For more safety in the dark, the 360-degree reflective yarn Albedo® is also located at the outer hem. The dense material structure envelops the shape-optimized Air-Conditioning Channel® 4.0, which ensures ventilation of the sole. The Lambertz-Nicholson Achilles tendon protector 4.0 with its newly dimensioned pads protects against pressure and friction above the heel.
