    Arc'teryx started off with footwear by making it better.

    Welcome to the new generation of hiking footwear with the burly yet ultralight Arc'teryx Men's Bora² Mid Backpacking Boot. The Bora² Mid has that same unique style and performance that we all expect from Arc'teryx. For starters, Arc'teryx constructed the removable Adaptive Fit liner separately from the upper in order to hug your foot with breathable, quick-drying mono-mesh for a truly customized fit.

    Arc'teryx slipped Gore-Tex's Performance Comfort Stretch membrane inside the Adaptive Fit liner for extremely reliable waterproof, breathable protection. Unlike standard membranes that only provide partial coverage, Performance Comfort Stretch wraps entirely around the foot from top to bottom in order to maximize protection. Best of all, you can remove the Adaptive Fit liner and wear it on its own around the campsite for extra comfort. The liner has a rubberized bottom for traction and long-lasting durability, and you can always replace it with an Arc'teryx Gore-Tex Mid Liner or Gore-Tex Insulated Mid Liner.

    The Bora² Mid also features a lightweight and surprisingly durable seamless upper designed to handle rock, snow, and ice with ease. This seamless upper features a non-woven, DWR-treated internal surface that sheds wet weather, PU-coated nylon for air permeability and abrasion-resistance, and TPU film for enhanced support and durability. The two top lace holes have integrated reinforcements to reduce stretching.

    Underfoot, Arc'teryx equipped the Bora² Mid with a premium injected EVA midsole designed for stability and enhanced braking. The 3D molded toe and heel caps buffer impact, offer rock protection, and resist cracking. There's also an anatomical arch shank, and the custom-developed 3D molded Ortholite footbed offers maximum comfort and breathability.

    For the sole, Arc'teryx worked in collaboration with Vibram to give you the best traction on any trail. This sole includes a climbing zone with traction grooves, grippy inserts for smearing, RockGrip technology with anti-slip lugs, a mountaineering-inspired heel tread for stability, and a spherical heel shape for a smooth stride.

    Handled wet/cold weather comfortably!

    • Familiarity: I've used it several times
    • Fit: True to size
    • Size Bought: 11
    • Height: 5'11"
    • Weight: 180lbs

    I figured I'd write a review because I used these in some pretty nasty weather and my experience was comfortable enough that I felt they deserved a positive review.

    I wore these on a 6 mile hike in Galena, IL that switched between wet leaves, gravel, paved path, and snow/slush covered tall grass. It was also raining throughout the entirety of my hike.

    I'm thrilled to say that my feet stayed dry even after sloshing through the tall snow covered grass. They gripped the slick paved path well and I experienced no slips on an ice covered gravel road.

    If I had a complaint it is that Arc'Teryx seems to make their shoes fairly narrow and that when switching to simple terrain they felt a bit overkill.

    I also will share that the next day when I went to put them on - the outer lining of the boot insert still felt cold and damp. I slid my foot in and it did not get wet, but I feel like this would lower the overall insulation/warmth of the boot and I did feel like my foot stayed colder the next day.

    All in all I was thrilled with the performance of these boots, but as a word of advice - even though they are GTX make sure to dry them out thoroughly if possible before putting them on again.

    Outstanding boots with great features

    • Familiarity: I've used it several times
    • Fit: True to size
    • Size Bought: 12.5
    • Height: 6'5"
    • Weight: 225lbs

    I purchased these boots for use on everything from simple day hikes to extended-length backpacking trips. I wanted a product that was versatile enough to serve as a single solution for these uses. The Bora2 GTX Mid is precisely that; sure, they're overkill for causal use, but they're so lightweight and comfortable they serve the purpose perfectly well, while also being built tough enough for long backpacking trips.

    The fit is important to get right, and you'd be well advised to spend time ensuring your fit is spot on. I typically wear between a 12.5 and a 13, and due to the slightly narrow design of these boots, I opted for the 13. Once I got them on, I realized they didn't fit quite right, and that the slight heel slip would be sure to yield blisters. Thanks to Backcountry's excellent support team, I had an RMA slip and a pair in 12.5 at my house in no time. Once fit perfectly, these boots really started to shine. Out of the box fit is excellent, but they continue to get better with use. This is obviously typical during break-in of a new boot, but I didn't expect it as much with these, primarily due to the materials used. I was wrong; they continue to fit better and get more comfortable with more use.

    Regarding waterproofness, I'll admit I haven't stood in tubs of water to prove the point like others have, but I can attest to the waterproofness of these boots during field use. I've hiked in the rain, snow, mud, etc. If what you're traversing isn't deeper than the inner boot is high, you're not getting wet, simple as that. And due to the breathability of the GoreTex inner bootie, sweat is able to make its great escape, allowing my feet to remain comfortable and dry no matter what I trudge through.

    About the inner bootie, it took a moment of getting used to, but now I love the design. The fit feels custom; comfort is exceptional. And on backpacking trips, I love the flexibility of being able to use the bootie as a kick-around shoe for camp, without the weight of carrying a second set of footwear.

    Support and traction are both excellent on this boot as well. I've done a substantial amount of side-hilling in these boots; the tough outer boot provided tons of support for my ankles while the fantastic Vibram outsoles ensured I never lost my footing. Grip for days on ascents and descents alike.

    The only negative I could level against the Bora2 GTX Mid is the supplied insoles; these were immediately replaced with a set of green Superfeet to ensure optimal comfort and support, and to reduce fatigue. This is typical on pretty much any boots, so perhaps not worth mentioning. But there, I mentioned it.

    In summary, these boots definitely DO live up to the hype in my opinion. Arc'teryx have hit a home run with these outstanding, versatile boots and when I wear them out (hopefully not for a long, long time), I'll be back for another pair. Buy with confidence; these really are a fantastic product.

    Outstanding boots with great features

    These are great boots.....almost

    • Familiarity: I've used it several times
    • Fit: True to size
    • Size Bought: US 10.5
    • Height: 6'3"
    • Weight: 225lbs

    I got these boots about a month ago and have worn around my house a few times and taken out for two modest length hikes (6-8 miles on rough terrain)). My first impression is that they are awesome. They are REALLY LIGHT, almost 200 g per boot lighter than my favorite Asolo boots, the soles are very grippy on a wide variety of terrain and the narrow toe box is great for climbing and getting the boots into cracks and crannies on steep stuff. I haven't really been out in wet conditions yet so I can't comment on the waterproof qualities of the internal boots.

    The big issue for me is heel blisters. I am pretty confident that the boot is properly fitted. I've tried in thin liner socks, low cut Iniji socks and bare foot (for a very short time - extremely uncomfortable). It seems that where the rigid heel cup ends the bootie flexes and folds on the hard plastic of the heel plate and that fold rubs my heel. I think this is possible because of the very soft and flexible outer shell. I've tried wearing very loose, super tight and in between and I get a blister in the same spot every time. And oddly enough it is more of an issue on the better fitting boot. My other smaller foot does not have this problem despite fitting more loosely. (I should also point out that I've worn many brands of boots over the years and never got blisters in any of them). I'd be willing to bet if the bootie did not have the rigid sole for use without the shell I wouldn't be having this issue (which of course would also eliminate one of the product's benefits). Going to try with a regular hiking sock to see if that helps. Other than that they're very comfortable. And even though the toe box is narrow for whatever reason it really doesn't bother me with wider feet. I think the bootie helps with this by creating a somewhat "custom" fit, which was my hope when I bought them.

    Other than that glaring issue the boots are great. I'm curious to see how the outer shell holds up over time with rough use. The materials seems very soft and pliable and I can't help but wonder if it will tear, puncture, etc. with rough use. I also noticed some stitching on the bootie already seems to be fraying a bit, which may be an issue with the waterproofing mentioned in another person's review. I'll have to monitor.

    Great Boots with one possible flaw

    • Familiarity: I've put it through the wringer
    • Fit: Runs small
    • Height: 6'0"
    • Weight: 130lbs

    I've been using these boots on a couple different backpacking trips as my only shoes. Typically I bring a pair of boots or shoes, as well as a pair of sandals or flip flops for around camp. But with the removable liners that actually have rubber soles on them, I've been able to simply use those. Plus, when I wear them around on their own, they breathe better out of the boot and seem to dry off pretty quickly.

    The boots do run a little narrower, so be careful on that for sizing. Other than that, they broke in very quickly for me, and they haven't had any pressure points or hot spots during the time that I've used them.

    As for practicality, the soles and versatility of the boots make them excellent for almost any terrain, they grip well, have great support, and break down with the liners to make an entirely separate pair of shoes.

    My only problem with the boots is that my liners seem to have either lost some waterproofing ability, or never had it in the first place. I'm noticing now, after around 100 miles put into the boots or so, that the liners will take in a little bit of water if fully submerged, but not to the point where the gore-tex ends. It's not enough to even notice at first, but I've noticed my socks are just a little damp when I take them off afterwords. Other reviews lead me to believe that this is caused by the stitching in the liner, but mine could also be isolated and only require a warranty claim.

    Overall, I'd highly recommend them. They dry incredibly fast, much faster than anyone's boots that went backpacking with me that didn't have liners, the removable liners are a necessity that I didn't even know I needed until I had them, and the overall quality of the boots is well worth the insane price tag.

    It doesn't breathe will

    • Fit: True to size
    • Size Bought: 9.5
    • Height: 6'2"
    • Weight: 170lbs

    Just as OUTDOORGEARLAB said: The bootie is surrounded by a thick upper of leather, and it didn't breathe well at all. Our feet sweat uncomfortably when active in warm temperatures, and still generated unwanted moisture inside when hiking in cooler climates.

    The first product Arcteryx disappointed me.

    Good for weekend warriors...

    I personaly love arc'teryx and own a pair of pants and hardshell jacket, and they are so great i thought why not give their boots a try too? I loved the concept of the removable waterproof liners and durable one piece rubber shell. The first (Short) trip i took these on they worked great, comfortable and sturdy, a perfect fit. Later, after going on a 300 mile trip through Maine on the Appalachian trail with these, this is what i've learned. Almost every through hiker i encountered had been through 3-5 pairs of shoes, waterproof and non waterproof, trail runner and sturdy boot, and every variation of trail footwear. Almost every experienced hiker told me DO NOT WEAR WATERPROOF FOOTWEAR. Here's the reality of long distance hiking. You are going to get wet, you will sweat in dry weather, and you will sweat in your fancy gore tex pro or pertex or event raingear. Period. You will get wet and you will have to accept it and deal with it, which is why experienced hikers wear non waterproof footwear, which is more breathable and will dry faster than any pair of waterproof boots. I don't care what they are made of or how expensive they are, it is foolish to believe you will not sweat and that you will be perfectly dry in stormy weather(or even dry weather), or that they will dry out overnight. The key to happy dry feet is to stay at home and wear your favorite pair of slippers. But for those who do endurance hiking and spend months on the trail, they know the key to happy dry-ish feet is to wear a pair of footwear that will let your feet breath and can dry out quickly when they get wet, a.k.a. anything without a waterproof membrane. I'm not just speaking about these boots in particular, im speaking about every boot. "But these are gore-tex they will breath, and they have a removable liner so they will dry out overnight." I thought the same thing as you, i wasn't experienced either. If you still think i'm wrong and believe these boots can defy the laws of hiking, go ahead and spend $350 for these, and maybe you'll learn a valuable lesson like i did. I wanted to love these boots, and i do, i just won't wear them for any extended trips until Arcteryx comes out with a non gore-tex liner.

    Thanks for your review, Aiden. I cannot agree more on the fallacy that is GTX boots!!! I spoke to customer service at Arc'teryx to see if they would be producing a non-GTX liner: they said I was one of many who had asked, but they weren't sure if any plans were being made to make it happen. Seems so strange when it should be so easy to make happen! I think your review may be a bit harsh though when all you talk about is something that most bootmakers are doing right now. How are the boots otherwise?

    Another Great Arc'teryx Product

    • Familiarity: I've used it several times
    • Fit: True to size
    • Size Bought: 11.0
    • Height: 6'0"
    • Weight: 195lbs

    I was a bit skeptical to purchase these boots, for several reasons. Arc'teryx footwear line is fairly new, the removable liner and how can it be waterproof, and the upper liner material being very comfortable

    . I took the leap and would gladly do it again! I love just about everything about the boot. The removable liner has come in handy a few different times around camp to use a slipper, or even cold nights it can act as a bootie. To this point too, is the insulated liner that is available separately. Now the boot is extended to be used almost year round. The vibram sole has great traction, even on the wet rocks of the Adirondacks that I used them on several times.

    The only minor issues I have experienced with these, was the first speed hook can actually do its job too good. When untying, my laces have gotten stuck and takes a bit of some pulling the get the lace out. The only other thing, was that I have some above average wide feet, so the first few times wearing them, right below my ankles would start to hurt. I would loosen the laces and then would be fine, and this pattern ceased after maybe 3 times using them on very short hikes during the break in period.

    The fit was true to size for me. I typically am an 11 in majority shoe brands, and was the same case here too. I didn't experience any blistering with these boots at all, however, I am not typically one to get blisters from new footwear.

    I would definitely recommend these boots for hiking/ backpacking. If you have any questions about these boots, or any other gear, feel free to reach out to me directly!

    Another Great Arc'teryx Product

    I love arcteryx

    • Familiarity: I've used it several times
    • Fit: True to size

    They can't seem to make a bad product... Worth every penny for the warranty alone but the quality is just un-real.

    The liners are machine washable and can be used as socks... at least I use them as socks. (Its a little strange wearing socks under them in my opinion since the liners can be machine washed) Laces are even of a better quality then your typical hiking boot. 100 percent water proof and yet still breathable. The outer shoe is goretex as is the liner.

    As a side note for those of you like me with slightly wide feet they can be worn but they will bulge a little. These are made for a narrow or "D" width foot. I usually get an "E" and they bulge a little. "EE" or wider these wont work for you Im afraid.

    I love arcteryx

    Amazing out of the box.

    Recently completed a trek up Killimanjaro utilizing these boots. Rained constantly the first two days. Feet stayed dry and the liners dryed out easily overnight. I did use the optional thermal liner for summit day. I believe I would have been fine with the mid weight liners. No issues with hot spots and loved that I could use the liners as camp shoes.
    No reservations about these boots.

    The future of Boots

    These boots are amazing!
    They fit true to size and are wearable right out of the box. The inner liner is great and takes away any friction or hot spots. I put them on and did a significant backpacking trip without any break in. I love the liner for wearing around camp and have worn them to bed a few times on cold nights. They are waterproof but breathe well and dry quickly. My favorite thing about these boots is the durability. The outer boot has no stitching and is seemingly indestructible. I've taken them up 4 14ers and have yet to see any wear. Definitely worth the extra $$.

    Great boot, removable liner way to go

    • Familiarity: I've put it through the wringer
    • Fit: True to size
    • Size Bought: 10.5
    • Height: 5'11"
    • Weight: 148lbs

    I've worn this hiking, scrambling, on approaches and a bit through talus. Just got back from Switzerland and spent several days hiking all day in them. Not only are they comfortable but you notice the difference in weight with traditional boots.

    Boots look very sharp, seem well made and fit true to size. I love how light they are compared to leather boots. I always feel sad for my friends with bulky heavy boots. Vibram soles work well as expected,v ery grippy and good all around.

    The best part is the removable liner, I dont know if it conforms to your foot etc but, being able to take them out as a camp shoe, to dry, to wash etc is just so darn practical.

    I've spent all day walking through snow and my foot stayed dry. I noticed some wetness in the liner after finally removing them but it didnt make it through to my foot. Yeah! Also the liner dries quickly once taken out.

    Also, the fact that the shoes have no tongue I find to be a huge benefit.

    Unanswered Question

    Does anyone have experience wearing these boots in warm/hot weather? I'm currently looking into buying new lightweight hiking boots and am looking for a pair that can handle cold weather but can still be somewhat comfortable in temperatures in the high 70s and low 80s.

    Weird question- are these non-marking soles? I.e. awill they leave marks on fishing boats?

    Unanswered Question

    Your tech spec list the Bora 2 as an Ultralight backpacking boot. Will this shoe not hold up well for 7-10 day trips carrying 35-40 pound loads. I'm an old weightlifter and still carry 260# of body weight.

    Dear Backcountry,

    I would like to ask for some information on the boot Bora 2.

    Do you have the separate weight of the boot and the liner?

    How comfortable is the boot without the liner? If I go for a hike in a very dry climate, is it possible to use the boot without the liner, but with trekking socks?

    Now about the size: the presence of the liner will make me buy one size bigger, or half size is enough?


    It is not possible to wear the shoes without liner.

    First, I have US8.5, without liner, it fills like US 11

    Second, it doesn't have tongue, so without the liner, shoe lace will be on you socks directly. I think it is not ideal.

    I wear the North face US9, Merrell US8.5, Salomon US8.5.

    I hope this may help you.

    So, what I am hearing is they run NARROW in the Foot Box?

    Best Answer

    I wouldnt say narrow, it does depend on the foot. I tried them on and them seem pretty standard. Not wide like a Keen by any means but, not a narrow La Sportiva fit either. Feel free to give them a try, Ill cover cost of return shipping to you via a free UPS Label.

    You can call or email me directly. 801-736-6398, or

    According to ARcteryx additional liners are available, such as an insulated one. When will these be available? A

    Also, are you supposed to wear socks with these?

    I tried with and without socks. Definitely WITH socks is better. ANd thanks for the liner info. The website isn't clear on how much difference the insulated one makes vs the standard. I wore these outdoors all day Saturday at about 32F and was fine with basic hiking socks and the normal liner.

    What kind of crampons would work with this? ANd how suitable would this be for non technical alpine hiking, via feratta, glacier crossing, non vertical climb/ice?

    Best Answer

    Strap on crampons will work with these boots. The footwear line was designed for light hiking and approach. They'd be great for via feratta, glacier crossing and non vertical climb/ice. An insulated liner is offered separately for cold weather objectives.
