"I've owned a pair of these for 2 seasons now wearing them at least 4 days during the week at a ski resort I work at and love them. I just wanted to get another pair to have on hand but probably won't need them for another 2 seasons. I get these a half size larger just to give my toes a bit more wiggle room. Very warm in the cold winter conditions when outside for long periods of time. I also wear these when I go snowshoeing. Highly recommend these boots."

"I’ve had my pair of Keen Polar Revel boots for about three years, and they’ve proven themselves to be outstanding cold‑weather performers. I’ve worn them snowmachining and snowshoeing in the backcountry of Alaska in temperatures ranging from –25°F to –40°F, and they’ve kept my feet warm and comfortable every time. The wide toe box is a huge advantage for anyone who needs extra room, and despite long days of use, I’ve never experienced hotspots or discomfort. For the best cold‑weather performance, I recommend sizing up and pairing them with heavy socks."

"I bought these boots for wearing in a iceland winter. Due to go soon. Boots are warm and I feel very protected. The website said to buy a half size bigger. I bought my normal size and they fit fine. I have bought many Keens over the years and also find them reliable and hard wearing. I am lucky in that i can wear the straight from the box"

"Boot holds up well but gets cold after 20 degrees. Not a sub zero boot."

"Well made, high quality boot, that is comfortable. OK so far down to freezing temperatures but not yet worn in snow/subzero."

"Comfortable boots and keep my feet warm. As recommended, I purchased a pair 1/2 size larger than my normal size. They fit perfect."
— Robert A. (5/5)
"I bought these boots for the advertised lab tested improved traction on icy surfaces. They do not have any better grip on ice than any other boot that I have worn over the years."

"Very comfortable and warm. The eyelet aove the toe cap is a bit superfluous. the last two eyelets before the hook need to have some sort of jammer (like Altberg boots) on them; you pull them tight and then they slacken off before you get chance to complete the lacing. Not sure how waterproof they'll prove to be. . ."
