I have owned many high quality snow boots. This Summit is not one of them. My family has enjoyed all their summer shoes and sandals from keen and so have I. It was quite a surprise to find out that the typical Keen high quality did not transfer to this boot. It is simply not completely waterproof. It does not leak ,but it builds enough moisture around the toes to begin to feel very cold. I thought it was just me but after living my whole life in Montreal winters I can honestly say that Keen has failed with this product.
