So like many other reviews, the socks are really tight. I'm 9 1/2 large foot (actually sometimes EE) and they are tight. I really like the feeling of wearing them (soft touch inside), but they are also very warm. you would only wear them in winter (-5 to -30) otherwise I'm sweating. if I move them around my calf, I'll get marks when I remove them. Otherwise, the quality is nice.
