My Adrenaline GTS 22 fits perfectly. I'm 10 1/2 wide and love the fit. I used to have a pair of Glycerines and while they were very comfortable, they didn't offer any adrenaline support. Also, the heel wore out pretty quickly. My last pair of Adrenaline lasted a year and that was when I ran 2 1/2 miles 6 days a week. I also walk pretty fast to get my heart rate up. The only thing keeping them from being a perfect 5 star is the laces are too short to use the last few holes in the crossover to help the heel. Luckily I still have longer laces from the previous pair. If you use lace holes as they appear, the laces should be long enough.
