I am loving these boots so far. I have only used them a few times though. All I can say right now is that they are unbelievably comfortable and very insulated. I am doing wetlands research and am walking around in muck and water all day, sometimes on very cold mornings and these have been great companions. I do have to say that now that it it warming up they get too hot on my feet by the time noon rolls around. Can't wait to use them in the winter. I will also be watching the seam in the back, which has been the problem area in other boots, and if anything happens I will post another review.
