Bought this for my sister, who is a size 10.5 in puma. The shoe runs true to size and width, and a 10.5 fit her perfectly. She has long toes, and it accommodates them well without chafing against the front end. The sole provides enough cushioning for her running/elliptical workout, and her arches do not hurt afterward. All in all, a great buy!
EDIT: a year later and mostly used for light to moderate gymming, the sole of the shoe has separated. My other ASICS have done the same, so I wondering whether all ASICS have this problem. Also, sis has high arches, and after a few months of using this shoe, she developed foot pain after working out. I need to double check if I bought the right shoe for high arches, but its something to keep in mind.
