I'm a big fan of the Smart Wool merino clothing, and socks. It is expensive, but what in this hobby is not. After spending a day walking around in damp uncomfortable socks, I'd gladly pay 20-30 bucks to not have to do it again. I have tried many other brands of merino socks, and usually find the fit terrible, they tend to sag and bunch up throughout the day, making walking in them less than groovy. Cabellas makes or made a gray and black colored pair of merino socks in the outfitter line that fit well and are incredibly comfortable, but other than those all my socks are Smart Wool. There is another benefit aside from the comfort, they don't retain odor as easily as other types of socks making it possible to wear them multiple days without washing if the need arises.
