If you wear an 8M, do NOT order the 7.5M if you are a true medium. The toebox is not long enough to cover your toes correctly. There is quite a bit of 'toe cleavage' shown - from All toes! The joint of the pinky toe is not covered, causing the foot to look as if you are crammed into the shoe, a la Cinderella's Stepsister. I'm returning these with a heavy heart.
