so first thing ill say is these are probably the most comfortable boots ive put on my feet that said they are advertised 100% waterproof and i went on a hike and crossed several run offs and at the end of the hike my feet felt damp and socks were damp. so i decided to give them a call and they said that it was likely condensation from my foot heating up and the icy run off water. I thought this made since, id like to point out that they were very quick to say that i could return if i felt they were defective. there customer service seems great, but has anyone had any experience with this?
