We love these boots and order a pair every year.  Living in the mountains with rain, snow and slush- these are perfect!  The kids never complain that their feet are cold or wet.  These are definitely waterproof and worth the extra money as they serve as both snow and rain boot. (Our rain is always cold- so the added insulation is needed).  So far, we have passed them down & they still last and last- as long as the dog doesn't use it as a chew toy. Good traction but not wonderful--they are a little on the weak side with ice, could use room for improvement.  Overall, though, they are the best- and I think, are better than ones we have purchased from other major competitors.
