Be aware that these are not Dri-fit socks as some people mentioned in their reviews.  I've been on the hunt for no-show socks that don't get eaten by my shoes.  These are not the ones!  While they are thick and cushiony, they are cut extremely low in the back and still end up bunching up.  If anyone can help me out with black no-shows that don't end up inside my shoes, please send me a comment!
