I found this shoe to be tighter in the toe box than my Asics gel 260TR(which are very comfy). I thought perhaps I had ordered the wrong size, but not the case. I believe its that Clutch Collar System in the heel area that has actually made the shoe slightly shorter on the inside - pushing my foot forward into the toe box more. Rather than order a half size larger, I'll just search for another Asics without that "shoe within a shoe"! I'm going to send these back. Oh, did I mention, they are very pretty? :)
