Our Nordic Socks are made from Merino wool, a natural type of wool that's thinner and softer than regular wool, so it’s easier to wear. You can wear our socks with any shoe, and the warmth and comfort are guaranteed. This material also helps regulate body temperature. The Merino wool gets the sweat and moisture away from the skin via vapors and through its pores. It’s a natural type of wool, which means it takes care of itself. The vapors get out, the feet breathe through the material, and moisture and sweat don’t get stuck inside the socks.
