Great to put on when I have to run out for something, comfortable and fit well.  I find, however, after a few hours of wearing that they hurt my little toe.  Not sure why, they seem quite smooth on the inside so there is nothing there to irritate it and they don't feel too snug.  Several reviews noted they seemed to run small, but I did not find that.  I normally take a 5 1/2 shoe (would actually take a 5 1/4 if they made such a thing).  I bought the size 5, figuring 6 would be too big, and they fit perfectly.
