I was hoping that the blue would match the picture and I wasn't disappointed.  In flats I wear a 9M, if a wide is available I get those.  For the most part 9M.  The 9M for this shoe was $80 and 9.5W was $14.  I got the 9.5W.  The shoe fits great.  Not to stiff.  Of course, being a half size larger my heel kept slipping out of the left shoe even without knee highs and I expected this so heel grippers will be needed.  I would recommend this shoe, this color, if you are willing to spend the full price for the right size I recommend it, if you don't mind putting in a set of heel grippers and saving some money, I recommend it.
I have a blue sweater and a mustard pair of ankle pants that these shoes will look great.
