I.read a review that said i should order a size up to fit and i regret it.  These are my 2nd pair and they fit perfectly to size. Very comfortable. After a few times wwaring them my toes slide into place easier.  You can walk over any surface rocks cracks and you foot feels like its getting a message.  Totally protected ...  grate for use in the gym.....walking.....and generaly exercises. Totally awesome:)
