TOO SMALL
Size: Medium, Color: Blue
Nice socks, but they are way too small. Says they fit size 6 - 10. I kept 3 ( I wear size 8) and gave 3 to my daughter (size 8.5). We both agreed that they were just too small.

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.
