The Darn Tough Hunter Micro Crew Cushion Sock adds a lot of comfort to your hiking boots. Its mid-weight cushioning feels like you added a brand-new midlayer to your boot, and the merino wool blend fabric wicks moisture, dries quickly, and reduces odor. Darn Tough added mesh ventilation zones up top to amplify airflow, and True Seamless construction makes sure you don't feel the seam at the toe.
