I normally wear a size 9 shoe; however, this shoe was rather large for me.  I returned the size 9 and reordered an 8.5 which I am also returning because this smaller size also slips up n down on my heel.  I tried a heel pad which makes the shoe look even larger on my foot--creates too much space between my heel and the back of the shoe. I also ordered this shoe in midnight, both the 9 and the 8.5 and returned both of them.  These are such well-made, beautiful shoes.  Sadly, the fit did not work for me.
