I have found that Saucony are the only shoes that don't hurt my feet after a while, so I have several pairs.  I have these in both 8.5 and 9 (in other shoes, I generally wear 8.5).  I found the 8.5 were just a tiny bit too small (the tip of my big toe rubbed and hurt) and the 9 fits a little better.  But that having been said, the support is great (I walk and work out in these) and I would buy them again.
