The Smartwool PhD Outdoor Light Crew is a lightweight sock for hiking, biking, running and more. If you're outdoors and ready for adventure, the PhD Outdoor Light Crew will be happy to come along for the ride. The blend of merino wool, nylon, and elastane wicks sweat away from your feet and dries out quickly, keeping you comfy in your boots, hiker lows, or whatever footwear you've got on. The 4 Degree™ Elite fit system wraps your ankle, upper and lower instep, and arch with bands that allow for flex and recovery. I like to call it energy for your feet.
