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.

These socks last forever! I wear them daily. I bought my first pack over two years ago and haven't worn them out yet.

Snug fit
Size: Medium, Color: (001) Black / Black / Pitch Gray
These socks are by far better than the knock off versions. They fit snug and don’t fall down the heel when worn with tennis shoes. Would recommend
