The SmartWool PhD Outdoor Medium Crew Sock is a warm winter sock that's great for both casual and technical wear. The Merino wool blend knit is the same as what's used in SmartWool ski socks. It's designed to keep feet dry which, in turn, keeps them much warmer. The 4-Degree Fit System ensures a comfy fit that won't slide around inside your boots. Padding in the Achilles and flat seams in the toe provide extra comfort.
