Socks are one of the most important choices an athlete has to make. High or low, thick or thin… a good decision on race morning can make the difference between winning and losing. The low-cut, super light Pro Racing Socks Ultralight Run offers high-performance technology in an ergonomic package for running in extreme, hot and humid conditions. The anatomical design fits closely to the foot, offering unparalleled second-skin feel and exceptional comfort thanks to ultra-soft, all-over mesh. Ventilation is second-to-none so that your feet stay fresh and dry even in tropical locations. Stability wings give the ankle joint added protection from kicking heels while specially-located fibres act as hot spot preventers to ensure your soles do not burn up. Targeted compression boosts blood flow, while the toe box is lightly reinforced to reduce the risk of beaten-up toes and blue nails caused by repetitive friction against shoes.
