Excellent, BUT. . .
"Super cool, great for hot environments, reduces the sweat factor. . . the 'BUT' is about the top leg band. It's extremely tight for anyone with any calf muscle - affects circulation. My family have also bought these socks, we love them, but none of us can wear them without folding the tight top of the sock back over our boots. Unfortunately can only wear them with boots. In saying that, I have 5 pairs!"
