Customer Reviews KEEN Revel IV High Polar

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

I love these boots for winter! I wear them all day everyday and they are comfortable right out of the box. This is my second pair of these, I wore my other pair for 5 winters and figured it was time for new pair. I pull a hopper trailer and they are all I need for loading in below zero weather.

Easy break in, good warmth, good coverage.

Comfortable boots and keep my feet warm. As recommended, I purchased a pair 1/2 size larger than my normal size. They fit perfect.

This is an excellent mountain work and hunting boot. I have worn these for years - they last and keep your feet warm

I work construction as a project manager and these boots are comfortable, warm, and well constructed. Im looking to get many years of use from them.

One of the most comfortable boots I have put my broken up feet into !! The warmth is great and Im waiting to test the waterproof ness ice fishing

I typically wear size 9. 5 but had read reviews that suggested these boots run small so I ordered a pair in 9. 5 and 10. The 9. 5 size was a tight fit with the socks I would expect to wear (Teramar sock liners and Darn Tough Hunter wool) in conditions where I would need these boots. After wearing both around the house and on the treadmill, including mixing and matching the sizes, I decided to keep the 10. Even with two socks, my feet slide just a little bit, barely perceptible, in the size 10 but I thought this was preferable to a tight fit. This has not been a problem, even after an 8 mile hike in the Taconic Crest Range and the Adirondacks. No problem with the return of the 9. 5 and Keen promptly refunded my money. Have worn these boots several times over the past few weeks in temperatures ranging from mid-teens to mid-20s and for 2-6 hours at a time. Feet have been comfortable in these temperatures. That being said, I am usually active and moving except for short rest periods. Not sitting around a campsite or ice fishing. Conditions including dry but frozen ground, packed snow and up to 2 feet of fresh snow. Traction is good, even on flat icy sidewalk and roads and frozen dirt/rocky trails and packed snow. I have noticed that snow tended to accumulate in the tread under the heel, but not under the forefoot. This may have something to do with the condition of the snow, or the fact that the heel is more rigid. It did not seem to affect comfort or traction. They worked well attached to Altai Hawk skis and Tubbs Wilderness snowshoes. Am able to attach Trazon Microspikes but have not had the conditions to hike with them yet. The microspikes seem to fit securely in the treads so I expect they will work well. They have been totally waterproof, as I would expect from Keen. Overall, I am very satisfied with the boots and the buying experience from Keen.

Boot was advertised as waterproof. It isn't! I have other keen boots that 5 years old and still waterproof. These boots leak around the toes from just walking in the snow . Not what I expect from keen

Comfortable, warm, great traction in the woods and snow while felling trees.

My husband was so pleased with his boots that I gifted him for Christmas. He flies charter helicopters here in AK, so the warmth and durability of the boot really drew him to this pair. He cant wait to test them out!

I'm a fit and active worker but have a hard time staying warm, especially in my extremities. These boots are keeping my feet warm without fancy thick socks during full days when the temperature stayed in the teens. At the same time they're not so clunky and oversized to keep me from getting around the farm easily.

I went a size bigger. Boots I bought from you in October ran small. . A bit roomy so I put some inserts in an they fit better. Very comfortable. It would be nice if you made 1/2 sizes.

Not very comfortable and pinched at the ankle. Returned them for the lower version, theyre much better

Warm and comfortable right out of the box. I went with the size recommendation from keen and the fit is perfect with thick socks.

He loves these boots. Great fit, warm, great traction

not confident about the -40 rating ; wearing outside in + 20 degrees w/ carhart heavy socks shoveling snow ; 40 minutes --my feet were getting cold maybe change the cold rating claim to zero

Followed the sizing advice and bumped my normal 10 to a 10. 5! Perfect!

No more brace. We were looking for a high top boot that would support his bowed ankle due to paraplegia, we are pleased with the support. We wanted the added insulation due to cold feet and it has helped. We were concerned about not having enough room for the toesies but they run wide. We were concerned that his high arch would not allow him to get the boot on, but it was not an issue. We were concerned about fluoride issues because toxic socks was what was given him red and swollen feet but because Keen boots are PFAS free, that's not an issue. You can see from the unsolicitated photos that he is thrilled!!! Thank you Keen Boots

Tried to break these in short snow trail hikes. Left boot is uncomfortable at ankle/tongue region causing pinching pain on inside left shin. I even tried wearing very ultra thick socks but it did not alleviate the discomfort.
