Great fit but expensive
Size: Medium, Color: (252) Blush Beige / White / Castlerock
These are really great socks. I love them, but they are definitely pricey.

Great socks!
Size: Medium, Color: (252) Blush Beige / White / Castlerock
Love these socks so much I got a second package. I like how thin and airy they are and they never slide down my heel. For thin socks they’re pretty durable.

Great
Size: Medium, Color: (001) Black / Black / Pitch Gray
The best pair of work / workout / casual socks I've bought in long time! They're no show on all my sneakers, incredibly comfortable and they never move.

Great quality.
Size: Large, Color: (001) Black / Black / White
Thickness and comfort are great. Quality is great and the same I would expect if I bought at the branded storefront.
