I buy a pair of Keen Newport H2 Sandals for my son every summer.  They are the only shoes he wears for the entire summer.  He wears them on the playground - they are more comfortable and cool than seakers and socks but they are also sturdy, have a rugged sole for traction and a covered toe.  He wears them to the pool and the beach - they are waterproof and dry in an instant.  They look great with shorts and t-shirts and equally great with dressier polo shirts and kakhi pants.  They are possibly the most versatile shoe I have ever purchased.  They have been perfect for every occasion and it seems like there's nothing that he can't do in his Keens!!

P.S.  They even go into the washing machine (inside a sweater bag) when they need a little something more than a simple rinse with the garden hose to get clean.  Honestly, they look almost as good at the end of the summer as they did in the beginning.  These shoes are worth every penny!!!

P.P.S.  I loved these shoes so much that I had to buy a pair for myself too!!!
