Our thinnest profile sock, the Thinline is ideal for skiers and snowboarders wearing performance or freestyle boots, and looking for a tight fit through the foot and lower leg, for maximum dexterity and control. Merino wool is blended with Acrylic-Pillex™ face yarn for a high-performing outer, and the polypropylene/spandex lining is thinner than nylon and helps to insulate and wick away moisture. Thinline features nylon reinforced heel, toe, and extended foot zones for durability, while compression zones in the instep and ankle add critical support.
