Best socks I've owned - use them as uniform/boot socks. In the process of transitioning all my socks to smart wool PhD light/mid crews. I'll never go back to synthetic fibers!
One can wear this sock days on end when out on the trail. Each and every morning it is like putting on a brand new pair of clean socks. I wear these throughout the summer even in the hottest of weather. I have nothing bad to say about them whatsoever.
