For nearly as long as Ecco has offered this sandal, I have been buying these every year. I always have one brown and one atmosphere/ice pair. I have a narrow foot and the velcro straps let me adjust them to fit comfortably without socks. They give me enough support to walk 5-8 miles in a day whether I am traveling or at home. No blisters and no achy knees. I really appreciate Ecco for not tweaking this shoe each year like so many other shoe-makers do!
