Good quality
Size: Large, Color: (035) Steel / White / Black
These are a bit thicker then a compression sock and they come up higher on the ankle than a no-show sock normally does. They are very comfortable and soft.

Super comfortable, great quality
Size: Large, Color: (001) Black / Black / Pitch Gray
I love these socks!! They are very comfortable and my second order bc I love them so much! Also, they fit snuggly on my feet but not too tight. Best of all, they do not slide down my heels even when wearing my UGG boots.
