Heading to the slopes? Don't forget good socks – they make a huge difference. These FITS Light Ski socks are over-the-calf length, made from a blend of Superfine Merino Wool (66%), Nylon, Polyester, and Lycra. Merino wool is amazing because it naturally wicks moisture, regulates temperature, and fights odors. The fit is key here: they have a 'full-contact welt' so they don't sag, and compression through the foot and leg keeps everything smooth and stimulates blood flow. There's also a patented heel lock to help prevent blisters. They have targeted padding in the toe box, shin, and heel for a bit of cushion where you need it, but it's a 'light' cushion designed not to bulk up your boots. Perfect for skiing, snowboarding, or any cold-weather activity where you want warm, dry, comfortable feet all day. Just pair them with well-fitted boots.
