Really these feel like shoes, but from my experience of hiking the AT in these, I fell in love. They lasted so much longer than any other persons footwear I hiked with. The ankle support SAVED me so many times! And the customer service from keen when they finally gave out at over a 1000 miles was top knoch! I’d buy them again and again. If your looking for a boot that has the flexibility of a shoe this is the go to! Way better than altra or topo everyday! At least for me. I had a 10.5 wide and it fit perfectly with either a liner and a sock or just socks, I never felt like me feet were confined or didn’t have the room I needed for the inevitable swelling with hiking that far. Really an amazing boot, and it is waterproof! At least up to 800 miles of abuse. Keen ... MoreReally these feel like shoes, but from my experience of hiking the AT in these, I fell in love.

These boots are extremely comfortable, but the "bellows" will fail quickly and crack at the folds. I'm honestly surprised REI is still selling these given their failure rate. Keen either did NOT do the testing of the material they say they did, or the materials used in production proved defective.Either way, don't buy these unless you're okay with the gimmick of the flexible plastic not living up to Keen's promises. Mine cracked after only four moderate hikes in six months. Others reported this on the REI site when this model had a similar SKU.

I hate to write this because I've been a loyal Keen customer for 20 years. These boots will eventually tear on the flex part of the boot and leak. I purchased a pair almost 2 years ago and probably only wore them 15-20 times since I own multiple styles of Keens and wear all of them (I own 10 pair of Keens) depending on the occasion. These were worn just as a casual boot (not in harsh weather conditions) and the flex portion of the boot bends (ergo their name) and creates a crease that will eventually wear through. I wear Solomon Quest GTX as my 1-2 season Summer backpacking boot (June thru September) and Zamberland Viox GTX as my 3-4 season Winter hiking boot. My Solomon's have hundreds of hard miles on them and are still holding up great. I would expect more from ... MoreI hate to write this because I've been a loyal Keen customer for 20 years.

I get it, it's been over a year and if I was wearing these everyday and abusing them then I'm not writing this, but the wear is minimal and no way the boot should tear. Bottom line...this is a bad design.

I’m happy with these - they have excellent construction, needed no break-in, and are very comfortable. I’ve worn them on full-day hikes and to the office. They aren’t overstyled or overly bulky. However, in comparison to my Salomon Quest 4D GTX (which are overstyled and overly bulky), these still feel heavier and less flexible despite being a smaller boot and having the bellows flex feature. The tongue gusset is really low, and while I haven’t had to test that yet, it doesn’t seem very functional. There is also a noticeable ridge of hard material inside the toe box just along the toenail area of my pinky and ring toes, but the toe box is very ample so it tends to not bother me. The grip of my Salomon’s on wet rock and loose dirt is superior to these, I slipped more ... MoreI’m happy with these - they have excellent construction, needed no break-in, and are very comfortable.

The grip of my Salomon’s on wet rock and loose dirt is superior to these, I slipped more than I liked ascending with these boots. However, they lace up very securely around the ankle and top of the foot, so that combined with the massive toe box make these my most comfortable boot for descending.
I have previously owned many pairs of boots (Lowa, Meindl, Scarpa, Berghaus, Merrell, Altberg, Danner etc), and recently a pair of Keen Targhee 2 boots and some Salomon X Ultra 4 mid in a wide fitting. My previous Targhees were a perfect fit in UK size 10, this review is of the Keen Ridge Flex boots also in a UK 10.Most of my walking is in hilly terrain, often in poor weather which requires sure footing as it's usually rocky and slippery underfoot. I walk on average around 30 to 40 miles a week for pleasure and work purposes.The Ridge Flex boots seemed comfortable straight out of the box, however the supplied laces were too short and needed to be replaced with a 150cm pair so that all of the eyelets could be used without over-tightening them.After having walked ... MoreI have previously owned many pairs of boots (Lowa, Meindl, Scarpa, Berghaus, Merrell, Altberg, Danner etc), and recently a pair of Keen Targhee 2 boots and some Salomon X Ultra 4 mid in a wide fitting.

This resulted in bruised toes and a couple of lost toenails when descending one particularly steep slope.When tightening the boots down to the point where this movement is reduced, I have found the pressure exerted on my midfoot by the bottom of the lacing is extremely uncomfortable. This is despite the tongue being well padded and trying a number of different lacing methods to no avail.These boots look great, the sole is very grippy and the waterproofing is up to Keen's usual high standards. Despite this, I have now relegated these boots to occasional country walks and travelling where I’m sure they will excel.
I bought these for their usual use in alpine environments. They seem super comfortable, really good for brief running when needed with the profile of the heel and toe of the sole for the heel strike and roll off of the toe during a stride. The nice big Keen toe boxes seem great. I like the non-hook style lacing which runs most of the way up to the last 2 hooks. I bought a 0.5 US size larger than my normal running shoe, and it seems nice. I like the extra lateral ankle support and the super cushy sole for impacts. I can literally sprint in these boots for 50 metres and it feels almost like a running shoe. It seemed the sizing ran only slightly small, but only slightly, as mentioned perhaps 0.5 US. Altitude shipping arrived a day early, no issues.
Hello. I bought these boots in Europe (I clarify in case there is a difference between European and American products). They look stylish and good. Before that, I had 2 pairs of sandals and 1 pair of boots from the Keen brand and I know my Keen size - 9.5 US. (I also bought Revel 3, I will write a review about them on the corresponding page). The actual size of the Ridge Flex turned out to be larger than indicated. Even when I wear two pairs of socks, I still have a margin for length. The next claim, it is the main one - saving on trifles. The seam threads on my boots were torn. I did not attach importance to this right away, it was not striking, but over time, a month later, I began to pay attention to this, it began to be an eyesore.

Keen made good boots, but small savings and / or manufacturing defects spoil the impression very much. If there is any doubt in my words, I can add a photo of broken threads on the seams.I have been wearing keen shoes for a long time, I like the quality and style, but this time I got a bad pair. I hope that the management after reading my review will correct the situation. It's a shame to lose such a brand because of ... we call it "saving on matches"
Gave these boots a workout walking over the summer on rough ground in the Rockies. Wasn't mountain climb, just moderate terrain.At first I thought that they were too soft to protect my feet. Turned out the soft sole worked great for traction and comfort and protected my feet even though I could feel small rocks thru the sole. My feet always felt great at the end of the day.They are waterproof in snow on rain. Great boots with one problem.The rubber flex feature failed splitting at the hinge valleys. The rest of the boot still in good condition. Correction: I did have to " Shoe Goo" the rubber scuff piece on the side of one of the boots.I would buy another pair without the flex feature but then they wouldn't be "flex" boots.
I bought these boots back in mid May and it is Mid december now. I bought two pairs for 103.99 before tax. I have one pair for work and one pair for deer hunting/scouting. The pair I had dedicated for hunting and scouting are still being used up to present. I have cranked out probably 1000 miles in those boots in hill terrain, marsh terrain, flat terrain, and some rugged rocky terrain. I used and abused these boots and they still dont have a single hole in them. They are still very comfortable and still have use to come. The pair I have for my job has not gotten as much abuse so they are still in excellent shape. My only complaint about the boots is that when they get wet they tend to shrink quite a bit when dried out.

My only complaint about the boots is that when they get wet they tend to shrink quite a bit when dried out. But they stretch back out fairly quickly after lacing back up. One other complaint i have (which seems to be a trend with a lot of other keen boots i have purchased) is the one gromets on both pairs had fallen off. I improvised and got it to work out though.I am here again because I wanted to get some new boots lined up for the spring. I wanted to see if these boots were still listed for decent price. They are $14 cheaper now than when I bought them 7 months ago!! With that being said, my satisfaction with these boots is very high and i will be purchasing four more pairs of the boots right now.
Ok, so the boot is wonderful. Fit, great, weight, great, waterproof, great. The only reason I'm giving this a 3 star review is because the Rubber sole of my particular boots are already peeling off. I've had these for less then 3 months and have at least 200 miles on them. Ideally this boot would be even more amazing if they had a 1 piece rubber sole, rather then one with flex points where the glue has failed. i need my boots to flex but not fail. Last its a personal issue of mine but who actually needs all that bulky padding and/or insulation around the ankle. it seems like unnecessary weight
