Our Verdict

The Keen Revel IV Polar is a winter hiking boot with great comfort. The footbed is well structured, and the insulation provides a cozy interior. However, these boots aren't particularly warm, and they have a relatively low shaft height, making them more susceptible to water and deep snow than other boots. Their tread pattern could be better designed for more robust traction, and some components make us question the boot's long-term durability. On top of that, these boots are more expensive than other winter hiking boots that perform better. All in all, this is a nice boot, but can't fare well against other footwear offerings in our lineup.

Our Analysis and Test Results

The Revel IV is a comfortable winter boot with good stability, but it falls short in some key metrics compared to other winter hikers.

Warmth


The Revel IV Polar uses synthetic insulation to add warmth to the boot. Unfortunately, there isn't much of it, and our feet didn't stay warm in these boots when the temperature dipped below freezing. Even during our cold-water submersion tests in a local creek, our feet got cold quickly. We don't recommend these boots if your winter involves spending a lot of time outside in the snow or freezing temperatures.

Weather Protection


The Revel IV Polar is waterproof and didn't let any water in through the seams during our submersion tests. However, the boot and tongue connect only 5.5 inches off the ground, allowing water to begin to seep in as soon as the depth of a puddle or creek reaches that height. This is lower than other winter hiking boots on the market. If you expect to spend time wading through swamps or stomping through puddles, we wouldn't recommend this boot for keeping your feet dry.

Comfort and Fit


These boots are comfy footwear! The footbed fit our testers' narrow-to-average feet well, but they also have some room to accommodate wide feet. The lace pattern allows for a wide range of foot widths. The sole has foam in the heel, reducing the stress of repeated impact, and the insulation provides a cozy cocoon for the feet. These are comfortable boots to wear mile after mile, similar to other hiking boots for winter use.

Traction


The tread pattern on the Revel IV Polar is just ok. The lugs aren't deep, but they are angular and provide a decent amount of negative space. The toe and heel pads have a lot of rubber without much negative space, producing good traction on dry and rocky terrain but not much bite on snow or loose gravel. We wish the traction on these boots were better for use across a wide range of surface conditions.

Durability


In general, this boot has a decent durability. The seams are mostly double stitched, and the lace eyelets are metal. However, the boot has a lot of exposed foam around the entire foot, just above the rubber sole. In our experience with footwear that has exposed foam, this material will chip and scratch off easily with normal use when scraped on rocks and branches. Foam is a fragile material but provides good cushioning for comfort, and we are disappointed to see this material on the outside of the boot. Other winter hiking boots have rubber around the entire boot up to the leather upper.

Should You Buy the Keen Revel IV Polar?


The Keen Revel IV Polar is a pricey winter hiking boot with a comfortable fit but not much performance in warmth, weather protection, or traction. We think there are better winter hiking boots on the market for a lower price. The Revel IV is expensive compared to other high-performance winter boots on the market, and it doesn't perform as well as some budget-minded competitors. As such, these boots aren't a great value. If they fit your feet perfectly, that might be worth the money, but otherwise, they aren't worth the price.

What Other Winter Boots Should You Consider?


The Merrell Thermo Chill Mid is a comparable boot that is warmer, more comfortable, and offers better traction compared to the Keen. This lower boot is good for snow that lacks significant depth and offers a good boot for hiking and going the distance. If you think your trek will include deeper snow or colder weather, we think the The North Face Chilkat 400 II is ideal with even greater warmth and weather protection with better traction and durability.
