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 socks!
These are great low cut socks with padding in appropriate places. The shape keeps them from sliding down in my tennis shoes. I just wish more than three pair came in the pack.

My favorite socks! Fit great and don’t slip down in my shoes. They are cozy and cushiony. I love the colors too.
