These boots are very comfortable and are true to size, are not waterproof which I was wondering.  Very breathable, does not hold moisture in but, escapes through the fibers and material that they are made of.  And I liked them so much I purchased a second pair.  They are definitely a 5 star rating and I would like to add they are a size zip easy off and feel like you are not wearing a shoe at all!!!.  Great Product
