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.

Great socks
Size: Large, Color: (672) Super Pink / Blaze Orange / Super Pink
My favorite socks! Fit great and don’t slip down in my shoes. They are cozy and cushiony. I love the colors too.

Quality under armor product
These are so very comfortable they are thin yet keep my feet warm around the house while it’s snowing outside

Not bulky fit
Size: Large, Color: (009) Gray Dawn / White / Prime Pink
Thinner than UA other cushioning run socks, but this fit is perfect and doesn't shift in my shoe. I wear a women's 9.5 and determined Large doesn't squeeze my foot like Medium size (too exact). Bonus... avaliable olors beyond black and Grey.
