    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.

    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.

    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!

    I love arcteryx

    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.

    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

    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

    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.

    Are these comfortable, or are they hard and rigid?

    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?

    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?
