They fit so well I can wear them like running shoes without unbuckling them and they still stay on my feet. I walked around Paris in these clothes and didn't feel the usual treacherous grinding in my knees or a bad tear in my lower leg. Not that comfortable for long standing, but hey. they are sneakers. Some complain about the aesthetic of the wide outsole, but I find that they offer extra lateral stability. Already started to advise the owners of NB and Nike to pay attention to the line of Bounce shoes for greater comfort.
