Haven't worn these shoes yet, but they feel as if they won't give me any issues.  The heel height is perfect!  Not too high and not too low.  This alone will make walking in them easier, yet give a little lift, ensuring better posture that flat shoes most certainly don't.  Really, for the price, you can't beat this great summer sandal that will go with most anything - jeans, little shift dress, Bermuda shorts, etc.  4 stars because I haven't tried walking any distance in them yet......
