We worked with athlete Rob Krar to create the ultimate ultra-run sock. This purpose-built sock features Shred Shield™ technology to reduce wear from toes, activity-specific minimal and targeted sole cushioning, and a new malleolus ankle cushion designed for protection on the most rugged trails. These socks were built to go as far as you want to go, with unwavering comfort and performance.
