Between night laps and dawn patrol tours, the Smartwool Ski Full Cushion Midnight Ski Pattern OTC Sock keeps our feet plenty warm. Merino wool lends its wicking, thermoregulating, and odor-resisting powers to create the perfect sock for any hour on the hill. Smartwool's Indestrucawool construction, 4 Degree fit system, and Shred Shield tech offer a better fit and lasting durability, so we can ride night after night.
