Cooler Feet

Our Extra Protection Hyper Thin® socks combine moisture fighting Drymax fibers with PTFE(Polytetrafluoroethylene) fibers to that reduce friction. The result is advanced protection against blisters in the lightest sock possible.

PTFE has the lowest coefficient of friction of any fiber, making it the best at reducing friction between the skin and sock. Low friction allows Extra Protection socks to stay cooler and drier, reducing the chances of hot spots & blisters.

This system has PTFE fibers in the heel, forefoot, and toe areas of the socks. These socks are designed to be the lightest and thinnest socks built with PTFE fibers in the market.
