Love these sandals and the color. I wear 7/7.5 with narrow feet. Got these in 7 and they fit like a glove. Usually with wedge sandals it is better to get half a size smaller as this style tends to slip off the foot while walking because of the height of the heel makes the foot slide a bit forward.  I had similar style in other brands which were non leather and they stretched, so definitely these being leather will stretch even more.
