This is the forth pair of SmartWool scoks that I have bought and I just love them. I really love the Margarita sock. It is not as think as my other pairs so I can wear them with my nicer work shoes. Because of the colorful strips, I can wear them with just about any pair of pants I own. I live in the Pacific NW and during the winter it is always chilly. I have to have warmer socks or my feet just stay cold. I never have to worry about that with SmartWool.
