I have been buying Keen shoes for my kids since they can walk.  These shoes are very sturdy.  My kids have worn them everywhere; they are great outdoor shoes without the socks.  I throw them in the washing machine when they get dirty and they come out fine. It's just harder to clean the inside of the shoes where the toes are. I let them dry in the sun.  They are light weight.  I like the fact that my kids' toes are protected with a sandal.
