Just a quick question before I place an order: Is there a problem with ordering two pairs of shoes, with different sizes, to see which fits better, then returning the pair that is unneeded? Or is this pretty much frowned upon by you guys? Otherwise, maybe you could point me in the right direction in terms of sizing... I'm not sure if I need 9.5 or 10 in the CC Genius. I was between the two sizes with my Barricade IV's, and ended up getting 9.5's. How does the Genius sizing compare to Barricade IV's?
