I know this has been done before, but... I am looking for a pair of boots that are waterproof. Not water resistant, water proof. I currently have a pair of Dririder Air-tech boots, which are advertised as waterproof, but after 4 hours of riding in the rain, they are still drying out. They get soaked in anything other than a light sprinkle. So I am asking, what is a really waterproof boot? Not just keeps you dry in light showers, but will stay dry after many hours of heavy rain. And please, I am after personal experience, not advertised claims.
