These socks are great. A perfect weight for a hiking or work boot. They are snug, have good support, and don't get slippery when wet or sweaty (a problem I sometimes have with wool socks like Wigwam). I own about 20 pairs of various smartwools and I love all of them. I wear a womens 9/9.5 and always get a medium with a perfect fit.
