I decided to try Keen's running shoes for my fast walking and bumming around town. I had been wearing Nike Freeruns but the toebox was pretty narrow and cramps my feet. I do a lot of yoga and like my toes to be able to spread out, naturally. Keen sandles have a wide toe box. The Keen trail running shoes are not as wide as I would like but they are wider than any other running shoe I have tried in the past. Also, biggest bonus, I can leave the insole in the shoe and add my orthotics, which makes for a comfortable and less sweaty wearing experience. The toe box did stretch out to be very comfortable after wearing them for a big. The unique lacing path, the way it zig-zags over your foot, makes for an incredibly comfortable fit as well. I rated these a 4 star b/c I want a wider toe box that doesn't bend my big toe in; however they are my favorite running shoes I've ever purchased.
