Love the fact that these stay in place and don't slide into my shoe.  The only real negative about them, and it's not a small negative, is the seam across the highest point of the toes.  Very poorly placed as they can be abrasive while walking, running or just doing anything inside a shoe.  Athletic socks should be seamless; I've yet to find or wear a sock that I don't have to negotiate placement with the seam.  If they weren't so good otherwise, I'd return them.
