This style ran large, maybe 1/2 to one size, compared to other Merell shoes I own.    I also did not care for the styling of the back strap.  Although the adjustable feature is nice, the velcro closing does not match the dressiness of the front portion of the shoe.  The loose end of the strap curls up -- while this would look fine on a pair of casual sandals or beach flops, it looks cheesy on a dress shoe.  That being said, if you get the fit right and wear the shoes with pants (so that the back doesn't show,) these would be a very comfortable and nice looking pair of shoes for work.  The comfort level/arch support are excellent for a healed shoe.
