SmartWool was founded in New Zealand. A group of Ski instructors were bothered with cold feet while being on the slopes for hours. Through research they learned that the New Zealand Merino was soft, strong and white. As a result, SmartWool was in business. The Merino wool keeps your feet warm in cold weather and cool in warm weather. And, these socks will not allow odor bacteria to build up in the fibers. These socks are wonderful for anyone who is active such as skiers, firefighters, professional athletes, hikers, runners, cyclists and climbers. The Ski Light Sock is very popular. And for those days that you need to be in the office - you can also enjoy the dress slack socks that are available.
