I had high expectation of these boots considering they were #12 best selling men's shoes. I mainly wanted insulated boots that looked good.These were NOT waterproof. I tested them by filling the bath tub with 2-3 inches of water and standing in these boots - within 20-30 seconds both the boots let the water in. I am not sure if I got defective boots OR they are supposed to be only waterproof in light rain / light snow kind of situations.I did the same test with my Timberland Gore-Tex hiking boots and they didn't let any water in - no matter how long I waited.Also these boots are quite ugly - they are too wide for some reason.I am going to return mine.
