Ultra-light, technical running socks designed to improve breathability and comfort during running. All the benefits expected of running socks have been incorporated into their design. Firstly, their In & Out construction (without cut threads) and anatomical design provide extra comfort. Secondly, a ventilated mesh has been positioned on the top of the foot to ensure breathability. The construction of this sock also incorporates a support zone at the ankle, for improved stability when running, and a slight reinforcement at the toe for added protection and comfort. Its medium tension ensures that the sock stays in place throughout your effort. Finally, at 30.2g, this sock is the lightest in our range for a second-skin effect.
