I love them! I generally dislike the fashion of "hidden" socks that aren't actually hidden by the shoe, these don't do that. The socks are made to go on your heel and over your toes, so it fits a nice dressy shoe. The heel also has this thin soft plastic(?) pad on the ankle to help it stay in place. They fit very well and look like you don't have any socks on at all. They are also really comfortable.
