I have always had a hard time finding dress socks that are knee socks, stay up, are not so tight that they almost cut of my circulation, and are not like nylons.  These socks are soft, stay up all day, and don't have holes in the toes yet like most do.  If I had to choose one negative is that they are very long (I am only 5'4) but it isn't a real negative because I just fold them over at the top.
