My wife originally bought me a pair of these for my birthday (or was it Christmas?). I loved them, then went to EMS to get two more pair. These are easily the best pair of socks I've owned. Very comfortable, light-weight (but still soft and comfy), very breathable, and the black/grey look great too. They have a white liner inside that should help with sporting activities. I just wear them on a daily basis for daily activities (walking, driving, running occasionally, etc.). By far the best sock!
