What you love most about hiking fast is experiencing more things. More sunrises from the overlook, more high fives at the summit, more post-hike tea with friends back at the parking lot. And more terrain — asphalt to trails to scree to stone steps. So Keen took the room-for-your-toes comfort, protection, and stability of the iconic hiker and gave it a running shoe feel with a waterproof, engineered knit upper and all-terrain tread. 18 years in the making, Keen's original fit is built to hold your heel firmly in place and give your toes room to spread out. Move fast over a variety of surfaces with confidence, not stubbed toes. Keen's proprietary horseshoe tread pattern grips from heel brake to toe roll. KEEN.DRYA waterproof, breathable membrane that lets vapour out without letting water in. Perspiration and moisture naturally produced by the foot are able to escape, while at the same time keeping the wet out and the feet dry. ECO anti-odourThe insoles are infused with probiotic technology that naturally breaks down odour in sweat without heavy metals or hazardous chemicals.

I usually avoid waterproof shoes because they tend to trap water on the inside. These shoes are the exception. They are supremely comfortable with good support while also being lightweight. I don't know what strange alchemy allows them to stay waterproof while letting moisture evaporate from the inside. Whatever pact Keen made with the neatherworld is working. I bought the low-top version and wore them all summer. I recently picked these up to wear through the winter. I'll probably buy more when they wear out, but they seem like they will last a couple years.

I'm a longtime Keen wearer, and had no idea about this boot beforehand. I prefer faster lighter mid-height boots in all conditions and weather.Weight is 460 grams and 470 grams for a men's 10.5. Conditions ranged from frozen ruts and powdered sugar snow to late-day melt, mud and pavement. I'll cut to the chase: this pair of Keens is easily my least favorite hiking/trail boot or shoe in recent memory. Where do I start....The laces regularly came undone no matter how tight or loose or pattern. Only double knots kept them together all hike. Coming from the likes of a Merrell Moab hiker which stays tied from beginning to end, these were a small pain to deal with. Maybe a shoelace lock would be an answer.The insole is too thick and squishy and makes the toebox ... MoreI'm a longtime Keen wearer, and had no idea about this boot beforehand.

Maybe a shoelace lock would be an answer.The insole is too thick and squishy and makes the toebox restrictive even with thin Smartwools. I believe they made it thicker and spongier because the boot is very uncomfortable in the forefoot. Replaced with my usual Superfeet (black) it opened up the toebox tremendously and allowed a midweight Smartwool sock to help with the boot's discomfort. At least 25% of testing was with the Keen supplied insole, and I could not wait to rip them out.The "heel lock" seems gimmicky. It's high up in the Achille's, and has no bearing on locking in the heel. The yellow protrusion aka "heel lock" collects debris from the very shallow V-cut in the boot if you wear a shorter or jogger/tapered style pant; it's a funnel for everything to fall into the boot. And because of the aforementioned lace issue the top of the boot would lose its tight closure. Solution: double-knot the lace and always wear longer pants.Lateral support is minimal. Closer to a shoe than a mid height, and I wasn't doing a lot of steep off camber trails.What did I like about the boots? The melt, mud and collected snow never seeped in. I'm more of a mesh and merino type or a treated leather wearer, and temps were averaging freezing so I had no issues with hot feet, but I am sensitive to swelling with waterproof aka not very breathable products.Maybe the full boot version is the answer to my minor peeves. I found the mid to be a slow boot, if that makes sense. It's not springy, there's no perceived rebound and energetic spring with the lugs. My heart rate and perceived effort and fatigue level after training were always higher with this boot. It's not a fast trail hiker nor a very confidence inspiring all-day option, at least for me. If the full boot had deeper lugs it would not only help with traction but maybe add comfort and lateral support. I know this would take away any marketed or perceived "fast light hiker", but you can't be everything to everyone. Skip the mid, go for the full boot or shoe, throw in your favorite insole, and double knot. Or simply buy another waterproof boot if you really need waterproof footwear.

Compared to other similar boots I've owned, these are a bit lighter -- which makes them less fatiguing on long days. The lacing system works well to keep my feet from slipping around inside the boots; there is a somewhat elaborate system designed to keep heels from slipping, but the heel retention is really no better than other boots I've worn. The construction quality seems very high, as I would expect from Keen. On the sides of the ankles, there are little pads that seem designed to protect ankles from things you might bang into on the trail -- tree roots, boulders, whatever...a nice touch!Two important notes:1) For me, the sizing is spot-on. I'm normally a US 11.5, and these boots (in that size) are a good fit.

As an added bonus, the boots don't make my feet feel all clammy and hot, as is sometimes true of waterproof boots.Only time will tell on durability, but again, the boots seem very well-constructed. On the whole, these are now my favorite 'daily' boots for hiking and kicking around town in bad weather.

I was pleasantly surprised with this boot! I have never owned Keen hiking boots before, so it was an all around new experience to me. They are well built, light, and offer a lot of functionality. First let's start with all of the good stuff:-I took these out on a few casual hikes, and one with more challenging terrain and a day pack. They are definitely the lightest hiking boots I have worn, and that alone meant my legs felt pretty great after hiking.-These DO indeed feel like more of a sneaker or running shoe, and going over gravel, small roots, and on dirt, was a breeze.-I didn't have too many water crossings, but did intentionally go through some shallow water to see how the waterproofing held up. No leaks! Also no definitely no outer absorption due to the ... MoreI was pleasantly surprised with this boot!

No leaks! Also no definitely no outer absorption due to the breathable mesh--a problem I have experienced on waterproof leather boots.- The tread offers good grip, and does not get mud or pebbles easily stuck in the lugs.- I did like the way the laces and stretch KonnectFit system felt when bending my ankle more on certain obstaclesI have only two small concerns, one of which only time will answer.- There is something about these that just doesn't feel quite as stable underfoot and around the foot for larger rocks, big roots, etc. as other "heavier" boots I have owned. I don't know if it is due to the light weight, construction, or some other factor, but there were a couple of times where I felt there was TOO much feeling of the trail through to my foot. Never painful, my ankles didn't roll or anything like that, it was just noticeable.- Durability? With the outer material being mesh, and the elastic of the KonnectFit system, I do wonder how well these would do on rockier trails with jagged obstacles. They are fine after a few wears, so hope to see what several more hikes will do to them.Overall, a good boot for someone that wants to move quickly with a light feel, and tackle trails up to a solid moderate level!
I've worn Keen hiking boots for years, but have been a little disappointed with the last few pairs I had because it seemed like the large lugs on the treads wore down or split off more quickly than they had in the past, so I was pretty happy to see the smaller lug pattern on these new NXIS EVOs. I can't attest yet to whether or not they will wear better, but I can attest to the comfort of these boots. The heel feels very secure and the ankle well supported, despite the slightly lower rise on the boot. These boots are very light and flexible, but they were also very warm on a recent 30-degree, snowy day hike. The only things I didn't like were the fact that it can be difficult to wedge your foot into the boot initially as the opening isn't very wide and the insole is ... MoreI've worn Keen hiking boots for years, but have been a little disappointed with the last few pairs I had because it seemed like the large lugs on the treads wore down or split off more quickly than they had in the past, so I was pretty happy to see the smaller lug pattern on these new NXIS EVOs.

The only things I didn't like were the fact that it can be difficult to wedge your foot into the boot initially as the opening isn't very wide and the insole is hard to put back in again if you need to remove it for any reason, for example, if you sometimes need to hike with an orthotic. Otherwise, these boots are great for some fast hiking.
3 big hikes in a weekend right out of the box. Shenandoah National Park. 7, 10, and 3 miles. Comfortable. Couldn’t believe they still looked new with no obvious wear. Already ordered new insoles because I prefer something more robust, otherwise I’d give it 5 stars. Sizing seemed Keen normal.
Wore these for 10 hour work days straight from the box, and for a 14 mile backpacking trip after a week of having them. The boot is lightweight and flexible. The footbed and lace lock keep your foot in a comfortable position with room to splay your toes naturally while still providing arch support. The midsole is soft enough to feel the ground while the sole protects your feet and provises traction across many types of terrain. Waterproof through marshes and rivers.The first day backpacking i did find i was getting hotspots along the inside of my foot and on my ankles but i adjusted how i laced the boots to loosen up in the footbed and tighten down the heel-lock and ankle and i didnt have any problems the second day.
This is a fantastic hiking shoe and looks good too.I have a high arch foot and typically need to size up a half size and use orthotics in the shoes. These KEEN hiking boots also required my orthotics. However, my regular shoe size fit perfect once I placed the 1/2 length orthotic under the provided insole. I also had success removing the insole completely and using my full length orthotic.KEEN Men's Mid Waterproof hiking boots are comfortable right out of the box and no break in period is needed. I did not experience hot spots or blisters. I really appreciated the roomy toe box and the "heel lock" worked great on both steep inclines and declines. Even though this is a mid top, I found the ankle support/protection to be similar to my high top hiking shoes.

Even though this is a mid top, I found the ankle support/protection to be similar to my high top hiking shoes. The Lacing System stays put and I had no need to re tie the laces (see photo).The out soul is rugged and similar to others hiking shoes with both pros and the one con of being slippery on wet algae covered rocks. I did a creek crossing and purposefully dunked my foot into water deep enough to cover the toe box and up to the ankle portion of the shoe. My feet stayed dry and after returning to dry land the remaining water beaded up (see photo).Usually I remove my hiking shoes as soon as I get back to the car. However, I still had these on at the grocery store an hour later.I highly recommend these KEEN Men's NXIS EVO Mid Waterproof hiking boots.
I have foot pain that is easily ramped up by shoes, and activity. These boots were so comfortable that I wore them for several hours without pain.What I did not like: the rubber toe cap looks awkward to me (personal preference that does not affect the boots' capabilities); the grip on wet pavement could be improvement (I never slipped, but the boots would occasionally slide less than a 1/4"); the tongue is relatively low so water can in somewhere between 3-4 inches up.The negatives are minor to me, and are far outweighed by the quality and comfort of the boots.
Used this in the muddy trails of Georgia and Alabama during winter 2022/2023 as well as on a trip to the Colorado Rockies for a week in January of 2023. They were great at keeping my feet dry from the elements, and they were rather stylish. I had a few compliments on these Keens from friends. Because they are waterproof, spraying the mud off the bottom was not an issue (Georgia mud is thick and sticky). I was pleasantly surprised that they also felt warm (with appropriate socks) while I was urban walking around snowy/icy Breckenridge, CO. I felt secure walking on treated sidewalks that had a few inches of ice and packed snow on them. The laces held up well, and never got undone with a simple bow knot.

My one complaint is the yellow heel keeper which I believe is designed to keep your heel from rising too high while you're hiking -- my issue was that this yellow friction point made it annoyingly difficult to get my heel into the shoe at times; to compensate for it, I had to undo the laces more than I usually do with other shoes/boots. Although, I would recommend this for the outdoors and hiking, I would not recommend it for a travel shoe. I wore these traveling from Georgia to Colorado by plane since I did not have room to pack these larger shoes into my suitcase...traveling in them was far less comfortable than in my runners sneakers (which was packed in my suitcase). Once I sat down for the three-hour flight, I regretted the Keens, but I had no choice. Otherwise, these are definitely a keeper.
