I purchased these for my husband to replace some worn out boots. He wears them on a motorcycle and says the soles are very grippy and comfortable to ride in. He's worn them riding in the cold down to the 30s and has said his feet were warm the whole time. I bought them because they are waterproof and they come in wide sizes. So far they hold up great in harsh weather. and I hear nothing but raves. I'd definitely recommend them.
