"Keysocks DON'T show in any flat that I have worn them with, and your toes/feet feel WARM. Also, they go up the length of your calf, so your legs get a little extra layer of warmth during the cold season, too (I realized this when I wasn't wearing them last night and my legs were cold in just jeans). They aren't too tight or too loose-they fit perfectly. They also have sizes for thicker calves as well."
