This soft, lightweight sock is made from fine-gauge Merino wool so it\'s warm without being bulky and won\'t take up room in your shoes. It\'s super-stretchy for a comfy fit and is naturally breathable so your feet stay fresh and dry. The soft, comfort cuff gently grips the leg so it won\'t dig in or restrict circulation while the smooth join at the toe won\'t rub or irritate sensitive feet. Thanks to its natural climate control, it\'s a perfect sock for all seasons.
