Bought these to use on my fat bike this winter. They have been great in the snow, but yesterday I had to ride a section of snowmobile trail that was slushy from the mild weather this week. By the time I was done, my feet were soaked and I was able to wring water out of my wool socks. I was wearing gaiters that covered the top half of the boots. I understand when something is labelled water resistant that you will eventually get wet, but these are advertised as water PROOF. 24 hours over the furnace vents and they are still too wet inside to wear.
