"A good mood starts with dry, warm feet. At least on the ski trails it does. An often neglected, yet always important aspect of everyone's enjoyment while doing physical activity -  to keep your feet happy - is an idea that Smartwool knows, understands and delivers consistently in a plethora of conditions.  Whether I'm running, skiing, cycling, hiking or just hanging out - Smartwool socks always fit well, are comfortable and most importantly perform the way great socks are meant to."   -Devon Kershaw
