Cold, wet feet are a common reason winter runs are cut short. At the best they can make a training session miserable! With the EXTREME THERMO SOCK HIGH 2.0 you can keep training through the coldest, wettest months of the year.

Made with 100% neoprene, these thermal running socks form an insulating layer by allowing a small amount of water in, which is then trapped between your foot and the sock. This thin trapped layer of water is warmed by your body heat, causing your feet to remain warm.

The EXTREME THERMO SOCK HIGH 2.0 comfortable fit, with the seam free ankle cuff of the sock fitting snugly, without irritation or feeling too tight. Available in five different sizes, you'll find the perfect fit for you.
