Very Satisfied. AK tested.
Being a fan of Keen and needing a pair or boots for the winter, I chose the Keen Revel based on my past experience with Keen products and reviews of the boots. A very good decision. I have skied over 30 days this winter in Japan, Washington St., Canada, and Alaska and have worn these boots every minute of my waking hours when I was not in my ski boots and my feet have been extremely happy. They have slogged through water, slush, wet snow, dry snow, deep snow, over ice, and sub-zero temps and the waterproofing capabilities and insulation/trapulator have performed flawlessly. The only time my feet felt remotely cold was while snowmobiling on a frozen lake in Alaska for a couple of hours but that is well outside their intended purpose so I will cut them some slack! I rubbed some NikWax leather waterproof on them when I first bought them (not sure it was necessary) and not a single molecule of H20 has leaked through. My feet have stayed toasty warm in all conditions wearing only lightweight and mid-weight socks. One reviewer says he wears his all day at work (presumedly indoors) and claims he does not overheat but I find them a bit too warm to wear inside for extended periods. The sole has always provided excellent traction in all conditions. As for sizing, I am always a 9.5 or 10 and am wearing the 10, the same as my other Keen boots and sandals. I highly recommend this product!!
