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.

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.
