i bought some today, the advice from the shop was that you should aim for a size bigger because they are a quite tight ft, however they will give a little over time. hope this helped :)
You can't exactly upload a 3D representation of your feet, and no two pair of feet fit the same pair of boots the same way. Buying footware over the internet is one of the crazier (and hopefully short-lived) fads of the internet age. Go to a real sporting goods store with real boots, and get them fitted properly.
