I ordered these in the pink color and was really looking forward to getting them!  When they arrived I was delighted, at first.  They are SO adorable.  I love how the pink color has 2 different colors of pink!  But, I couldn't get my foot all the way in.  These shoes must run on the narrow size.  I do have wide-ish feet.  Sometimes a M width is too narrow, but this is usually in dress shoes (ie pumps, heels).  Just as often a W width is to wide (usually in sandals, sneakers, and slides.  Since these are slides, I thought they'd fit, but they didn't.  If you have a narrow or narrow-ish foot, these will probably work for you.  But if your foot, like mine, tends to the wider side, they'll probably be too narrow.
