I originally ordered these in a 10 (my normal size), since I was looking for a high quality, comfortable pair of pumps to wear to work. The 10 was way too large, to the point where while standing in  it, I could fit my entire thumb between my heel and the back of the shoe with room to spare. I re-ordered the 9.5, thinking they just ran a little large. Tried on the 9.5, and they were so tight that standing for a few seconds was painful. I think the shoe is well-made and attractive, and maybe the sizing will work out better for others, but it clearly isn't for me. Very disappointed.
