I'm a Darn Tough convert. I've tried all of the major brands over the years and the Darn Tough fit better and last much longer. I bough 2 pairs over 5 years ago and I finally wore a hole in them. I just sent them back for replacement and hope to get another 5 years. I know they are expensive but with the guarantee, my socks will last at least 10 years. Not much out there that lasts that long. I also have various smartwool, wigwam, kirkland socks that I wear but they aren't my favorite.
