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.

They’re pretty nice socks
Size: Large, Color: (100) White / White / Pitch Gray
I got these today. They fit ok. I was wanting some no show socks. These are great. You have to make sure of the size you buy. They’re durable. Comfortable. Keep moisture off your feet as much as possible. Highly recommend!
