Smartwool is the best
These are the socks that keep my feet warm, dry, breathing, and happy. I've had the same 8 or so pair that I've been wearing for 13 years, daily, 6-8 months a year. Over the years I've tried pairs of similar socks from various other top brands and none of them have lasted more than a few years. Unlike all the others, the Smartwools keep their form, don't fray, hardly pill, and are just now wearing really thin in the heels. I just ordered 6 new pair, but I won't be surprised if the old ones hold up another year or two.
