I would actually rate this 41/2 stars simply because I haven't had them long enough to judge durability and I would like a touch more arch support. But that's very personal and for someone else it may be perfect. But otherwise this is an ideal, easy to slip on and very comfortable shoe. Over the years I've worn Newport's, Venice sandals(no longer offered), Rialto sandals, Howser slip ons , and Brixen low shoes. I've bought 11.5 in all of these and that fits perfectly in the Rialto shoes with enough room for a medium to heavy weight sock. A side issue, if anyone from Keen reads this, is this site is very difficult to use on an iPad. It was very frustrating getting to this review page and I almost gave up.
