Revel IV Mid Polar Boot
Thriving in conditions where snow can be thrown from a boiling pot of water requires a certain degree of preparedness and fortitude. And the Keen Revel IV Mid Boot readily steps in from the frozen tundra to embrace your feet like a favorite, hearth-warmed blanket with thermal resistance down to negative twenty-five degrees F. As you sip the morning brew on the cabin patio, the recycled PET insulation closes in around your ankle to trap in long-lasting warmth for sensitive toes. And as the day’s adventure gets underway on the snow-covered trails, the molded rubber outsole provides confident traction and resists the penetrating cold underfoot.
Keen achieve this astonishing level of protection from the inside out, starting with a Heat Trapolator footbed, blending insulating foam and felt with a shied that reflects heat upward to your feet, and adds a form of bumper guard on the heel and sides that resists cold transfer from the ground. On the exterior, a waterproof breathable membrane of leather and mesh protects the upper shoe from any water ingress as you break trails in deeper snow.

Good winter boots
I volunteer with a search team and spend a bunch of time in the woods with a lot of off trail hiking in all kinds of weather. These worked well this past winter. Toes were warm. Feet were dry. Good fit with the wide toe box and good traction on all surfaces. They are heavier than my Targee IIs but that is to be expected.

First time Keen buyer
I'm always a little leery about buying shoes and boots online because sometimes even in the stores trying to figure out which size fits and feels the best is tough. . I've been looking for boots for a fall trip. My criteria was a hiking boot waterproof big toe box with a little bit of insulation. A friend said he was wearing Keen boots because he needed a wide toe box also. I looked your brand up and read a lot of reviews and the boots I bought checked all the boxes of what I was looking for. . they came very quickly and we still had cold enough weather here in Missouri to give them a test with some of the warmer socks I'll be using this fall I am very happy with them fit is good they're comfortable to walk in. I feel like they don't really even need much break in time but I do plan on walking in them as much as I can before or fall trip.

Warm and comfy
[This review was collected as part of a promotion.] These boots keep my feet warm and dry in single digit temps trudging through snow. I bought them half a size bigger so I could fit heavy socks inside. Worth every penny.

You get what is advertised
I ordered this looking for something warm and being reluctant with only 200 grams of insulation. . . Boy what a shocker, these boots are great. Think I found my overall new footwear

Great Boots!
[This review was collected as part of a promotion.] Just finished snow blowing with these boys in 20 degree weather. Feet stayed warm and dry! Should have included info on how to re-treat the boots.

GREAT BOOT!
Great boot. I was always a Merrell fan however, I have notice a decline in their quality in recent years. My last 2 purchases have been Keen and I am very happy in their quality.

Broke in three days.
[This review was collected as part of a promotion.] One of the lace loops on the boot broke after only 3 days of wearing these, where has keen quality gone?

Keen delivers again.
[This review was collected as part of a promotion.] Worked as a driver for UPS and Keen was the only boot I found that kept my feet dry and warm. The extra toe room is a have to when you're moving all day, and your feet sweat. The boot holds up with minimal maintenance some bee's wax twice a year and the leather is still good from 6 years ago. The tread however wears off with time.

They are very comfortable and warm. I have had them in several snow storms with dry feet. I really like the boots so far.

Not great, not terrible
[This review was collected as part of a promotion.] I wanted to love them. The fit in the ankle ( almost cankle) just wasn’t good for me. Good traction while I used them. The suede did wet out. I applied beeswax. The fit was just a deal breaker.

Would this boot work for flat pedal winter trail biking - ankle height & bottom lugs?
