A whopping 400 grams of recycled PET insulation closes in traps in long-lasting warmth for sensitive toes, while the grippy, lugged rubber outsole provides confident traction underfoot.

These boots are incredibly comfortable

These boots are incredibly comfortable and I did not need a break in period. First day I wore them for ~15 miles. No hot spots at all. I bought the gray ones. The only thing that could be improved would be making the lower tongue or whole tongue leather so that they’d be more water proof. One of my socks got a little damp during an ankle/shin deep stream crossing. The boots were more water resistant than I expected though!

I just moved to Ohio (from California) and have never needed any form of boot, let alone a snow boot. These were so comfortable and warm!! They aren’t so heavy where your foot feels weighed down, but heavy enough to feel stable. Great grip/sole. Very pleased with these!!!

Nice, comfortable boot

I haven't worn it outside just yet as the weather has not been for it but I am looking forward to use the boots when it comes to it. The only thing I have to complain is that the boot is not available in Wide sizes. My right foot due to surgery is wider than my left and I am not sure if it will be comfortable enough to keep it. Time will tell.

Warm and comfortable

These boots are extremely comfortable and fit my wide foot well. They feel solid like they'll last me a long time. I appreciate that the KEEN waterproofing is not Gortex and does not contain PFAS to protect my health and the environment. I look forward to using them this winter!

Perfect boots for Iceland

I probably tried on 20-30 pairs of boots before these. I have chronic sesamoiditis and arthritis in my big toe joints and it was impossible to find a pair of boots that didn't make that worse and could accommodate my high arches. I also have raynauds and my feet go numb very easily. I needed warm waterproof boots for a winter trip to Iceland. These were PERFECT. They kept my feet warm, pain-free, accommodated my aetrex insoles, and kept my feet dry. Even on our ice cave tour that involved accidentally stepping in a few holes that were filled with water, my feet stayed completely dry. Highly recommend these boots!

Excellent boot, narrow low toe area

I really wanted these to work but sizing up to accommodate my big toe made the ankle so sloppy that I was afraid of slipping. The hard rubber was so low that my toenails and pinky toes rubbed against it, causing pain.

Great winter boots with traction and comfort

I love these winter boots. I haven't tested them in extreme cold yet, but my friend has these exact boots and she swears by them. I wanted to write a review for the sizing. I sized up half a size to 6.5 based on reviews, but they were too large for me even with thick socks. I'm usually a 6 in sneakers, 5.5 in sandals. I exchanged for a 6 which is perfect.

Nice Boots

These are comfy and seem warm, got them after most of the super cold was over. However I did have to return and get a size smaller. Normally am a 6-6.5 but a pair of shoes i got here i had to go up to a 7 so I ordered a 7 and they were huge. they're very wide. go with your normal size.

feet get soaked

I am not really one for leaving bad reviews but I am just really disappointed in these boots. I work outside and got these based on the current reviews thinking they would keep my feet warm and dry for a work day. they were great for the first week. now we are about 4 weeks in and my feet and soaked every day. I take my insoles out and they are literally soaked. it really stinks being at work outside in the snow and also having your feet we soaked let me tell you. I am thinking that it is possible that these boots need to be treated with a weather proofing every week? to stay water resistant on the top, which I did and my feet and still soaked so now I am going to spend the next hour I guess trying to put wax on the leather and spraying the heck out of the tongue fabric as I don't have the money to buy a new pair of boots. these boots are fine if there is no powdery snow, but as soon as snow gets on the top part of the boot its soaked feet from there. I actually have mixed feelings about keen in general. I bought a pair of hiking boots from them because I thought they looked nice. they promptly feel apart. I actually got warranty money from those boots which was nice, got these boots even though I was a little hesitant getting something I had to rely on as I had a bad experience so far. and first I liked them! and I thought maybe I judged keen so quickly before. but now...I know it may seem like I am overly mad about it! and like I said I usually don't really leave bad reviews but after about the 10th day of trying to do my job with soaking wet, freezing cold feet in a brand new pair of boots I am a little upset. buyer beware.
