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!

Nice
Size: Large, Color: (100) White / White / Pitch Gray
Great for around the house. Nice fit. I have the Beetus so I've always got to have socks of some kind on when I'm not sleeping. I guess they'd be good for athletics too, beats me.
