I've been a 8.5M all my adult life and have gone down a size for more expensive shoes so, I knew that I should definitely order these in my exact size.  I couldn't have been more wrong.  These shoes are tight as heck.  I shouldn't have known better than to go with an off brand that I've never heard of.  I'll have to stick with what I know fits comfortably for all day wear, even though I may have to pay alot more for quality - Anne Klein, Clarks, Naturalizer, Nine West, etc.
