Description
Our Trail Run Ultralight Zero is perfect for those who like a super light sock, or to wear with cushioned running shoes. These socks enhance performance with an anti-debris cuff to stop dirt from entering and a reinforced toe seam to prevent any splitting. The Ultralight Zero has maximum mesh ventilation for a highly breathable and moisture wicking sock, providing comfort and breathability in every stride.
Built on a structure of LYCRA® and set by our Thermo Fit process, this ensures the sock returns to its original shape and size after every wash. Whether on or off the trails enjoy comfort and a close fit that doesn’t slip.
