I've had a terrible time finding quality mary jane style shoes with solid straps - the elastic and velcro ones give out way too quickly.  These seem to be very well made, and the straps are real honest-to-goodness buckles so they stay on (yay!).  My only regrets are that they are heavy shoes - I totally FEEL the weight of them while I'm wearing them, and they don't have much arch support (which surprised me, as I expected better from Dansko).
