SmartWool PhD Running Light Micro Sock (Men's)

The PhD Running Light Micro Sock by Smartwool is like a constant temperature gauge for your feet. If you are running to beat your PR or just jogging through the neigborhood, the PhD socks will keep your feet cool when hot, and keep them hot when cold. Wicking moisture from your foot keeps you from forming blisters or hot spots and with Smartwool's smartfit system, the four point banded compression system, you get support in your heel, arches and across the top of your foot. Extra cushioning under the forefoot and heel gives you added support to run farther and for a longer distance.
