I usually wear an 8.5 or 9 depending on how narrow the shoe is.  I ordered these in a 9 and they fit perfectly.  I have a high volume foot: wide with a high instep, so, shoes with straps are a hard fit for me.  The shoes fit great all I did was loosen loosen the velcro on the top straps to make it more comfortable.  And after wearing the shoes for about an hour I was able to tighten the straps.  These shoes stretch out nicely.  I have worn them on long walks and haven't had any problems with blisters or hotspots.

Con: If I wear them too many days in a row and if my feet sweat, they get stinky!  However, if I just air the shoes out for a day, the smell seems to dissipate and not cause a problem.  I haven't tried washing them yet, but when I do, I'll post an update.
