Review after 15 miles in Snow/Ice/Steep Hikes
EmmaRH3 years ago
These are actually really good boots - super light and indeed keep your toes warm (I've put them through 10-40F conditions. Did a ton of research before buying new winter boots, and then waited to review until I had completed a decent amount of trekking in them. Results: great ankle support and toe-box width. Decent grip, though anything serious here in New England requires microspikes or crampons (which fit on easily).
Comfortable, although after 10 miles the other day my left heel is rubbed raw. Not a fatal flaw, they're still new, and I'll add some moleskin to that part of the boot as well. Not overly clunky, and a good height for typical snow trails (anything above 2-3 feet and I'd probably add gaiters). Really happy with product quality, waterproofing and, above all, weight. Very satisfied with Keen, and REI.

Good fit but giving black bruise on midcalfs
Lotty3 years ago
Bought these shoes 2 weeks ago for my winter trip to Fairbanks for all kind of outdoor activities. I have a mixed feeling for these shoes. While the fit for my feet is right and comfortable, I did have pain above my ankle (mid calf) the first few days wearing the shoes. The top mid calf part kept pressuring my leg, but I thought I just needed to 'break' the shoes for first time wear and wore thick socks so I ignored the pain plus I did not have any other shoes for my trip. These were perfect for snow hike to Castner Glacier and stayed outside for few hours in what felt like -14 weather with deep snow. We were doing some Northern light photography.
When we returned from our trip on Monday 4/4, I found out that I had 2 deep dark bruises ring shape on both my legs like I had been chained, guessing those were from the pressure / pain I felt while in Alaska. So I am really having mixed feeling about these. I do like the shoes, but will these keep giving me black bruises everytime I wear ?

Great boot! Please advise re. needed repair
4 months ago
5 years ago, I bought what looks like the forerunner to the Women's Revel IV High Polar Waterproof Boot. I have loved them. Warm, great tread, light-weight enough and roomy enough that my insoles fit in well. Because we've had a stretch of unusually warmer winters w/o our usual snowfall here in MN, I haven't used them as often as previous-to-global-warming wintertimes. My problem is that the top 2 boot lace fabric loops wore through last year and it's really problematic. I don't know what to do. Please advise. From the photos,you can see that I have't worn them often. (I have no idea what store I got them at :(

These boots are just about perfect. Study around the ankle, good support, big enough for two pairs of socks or a one thick pair. I bought them for work in Antarctica. To be clear: they are very excellent hiking/walking boots. They weren't warm enough for me to wear for work outside, but aside from Baffins or Sorels, NO boot is warm enough for standing around on a giant iceberg. But there were PLENTY warm enough for getting to/from work, or walking/hiking in my down time. They are non-slip, but of course if you're walking on ice you will need to be careful regardless. One of the best purchases I made before heading south, no regrets.

Ok but not perfect
8 months ago
They are comfortable and the toebox is adequate despite them being a little pointier than my old Keens. What's really annoying is how bulky they are, so my winter gaiters don't fit. I literally can't overlap the velcro closure, or hook to the gaiter rindg. There also is no space under the arch for the gaiter strap, as there is under my old Keen boots. Finally, I can't get my microsoikes on these boots because of the pointier toe, so I need a larger size. When you design boots there needs to be more thought given to the various interfaces. My gaiters and spikes fit all my other size 9. 5 boots, Keen and Salomon, just not these. Get rid of that pointy toe please! If anyone else made a winter boot that didn't squish my toes I would send these boots back in a heartbeat. Having to buy new gaiters and spikes makes them an expensive boot.

A must for extreme cold hiking
4 years ago
These boots are ideal for hiking in very cold winter temps. The treads handle ice without issue so you can confidently traverse slippery conditions. They are incredibly warm and are true to the -40 claim. I have done many hikes this winter in -35 temps while in Canada. Very comfortable and roomy should you want to wear thick socks. The soles are thick with extra insulation but not so large as to make driving difficult, I've had no issues driving a standard transmission vehicle and managing the 3 pedals while wearing these boots. These are now a permanent part of my extreme cold gear.

Weird fit
3 years ago
I just got these in the mail today and was so hopeful. But they're going to have to go back. I ordered my normal size and I can't even say that they're too short. I don't think that they are. But the toe box is tiny on these especially compared to traditional keens. The top of the toe box was pressing down on all of my toes making them feel too small. I went ahead and ordered a half size up and had to get them from Keen direct because REI doesn't have the next size up. They will probably have to go back too but there's not a lot of options out there right now so I'm remaining hopeful

I tried another brand of winter boots of a comparable price and I’m sold on the Keen boots. I returned the others, which were heavy and weirdly fitting. The Keen’s are lightweight, warm and are super easy to lace up. I saw that some people complained about the toe box not appearing wide like some keen’s are but I haven’t had any problems whatsoever despite having a wide foot. The inside is roomier than they look. Initially the he footbed felt a bit too firm. I was worried they’d be uncomfortable, but they’re absolutely fine. I’ve already taken multiple snowy trail hikes and walks on the road. Because the toe box isn’t as bulbous as other Keen styles are, it was easier to put my micro-spikes. I’m generally between an 8.5-9.5 and bought the 9.5, so I would have ample room for bulkier socks. They were fine accommodating thick socks and toe warmers for a 5 degree day hike.

Good shoes, but only survive 1.5 winters
3 years ago
Boots are good. Warm and very good for winter hiking. Fits little large, but I love it since I have high arch. Boots are very comfy and almost no break in time. However, it only survive 1.5 winter and it started leaking now. I can't wear it anymore.
