I couldn't resist buying these shoes even though I figured they'd be a little close... unfortunately, I was right.  It would have been perfect if the shoe came in half sizes.  I wear 10 1/2 M but bought a 10 M because size 11 is usually too big.  That being said, they are super cute and everyone loves them on me (this eases the discomfort), I just try not to walk around a lot.  That's the only reason I didn't give these shoes 5 stars.
