Okay, so Keens these are not, but these are an awesome little every day sandal for the beach.  My 5 year old has had a new pair of these each summer and they are highly adjustable, comfy and endure serious wear.  They are not tough, hiking-style sandals like Keens (which we also purchase each year), but they are so easy for him to get on and off and allow sand to flow through so easily that I would highly recommend to anyone.  Buying his next size for our upcoming vacation right now...
