You don't need an advanced degree to recognize the long-wearing advantages of the Smartwool PhD Backcountry Sock. The merino wool and nylon fabric work together to minimize foot stink, regulate foot temperature, and manage moisture when you're skinning up to a slope. The 4-Degree Elite Fit System employs two elastics to combat slouchy sock syndrome. Light heel cushioning helps hold your foot in place and minimize chafing. Your shin won't complain about your boots since the Backcountry sock uses fibers of varying densities to cushion the front of your leg without making it feel like your calves are sausages in a plastic-boot casing.
