Spent the entire summer of 2011 (give or take a couple adventures) in nothing but my Chaco Flips! Excellent support, stay on your feet and look great. There is a break-in period of about a week and a half if you're feet aren't used to Chaco's straps. But soon enough you'll forget there ever was an issue. I fully expect to get 1, if not 2 or 3, more summers out of these guys.
