This shoe is the perfect "in-between" style - not as dressy as some flats and not as casual as an athletic shoe.  The fit is true to size (I wear a 7M) and the color does not rub off.  The soles do not make black marks on the floor either.  I wear mine with nylons or a very thin sock, but you could wear them without any foot coverings.  These shoes are so comfortable that I wore them all day straight out of the box.  They are already a favorite of mine to wear with jeans or slacks.  Try 'em, you'll like 'em!
