Socks for warm feet, so you experience the magical moments in comfort, no matter when they happen. So often, it's the marginal moments at the end of the day that deliver the magic. That's why we made our Guide Thermal OTC Sock. Priority number one is to keep your feet warm, so you can make it to the end of the day and experience the magical moments. Pure Merino wool is naturally sweat-wicking and provides insulation so your feet stay warm and dry all day. They have just enough stretch to stay in place and are naturally odor-resistant for a long lifespan.
