Arc'teryx Acrux AR GTX Mountaineering Boot for Sale, Reviews, Deals and Guides

Looking for a winter boot, I ordered this boot and the G2SM. While the G2SM felt like my regular Nepal’s, this boot felt like a sneaker. Really it’s something else. (I would caution it runs narrow). Performance wise, this boot climbs well and keeps your feet toasty. At 0F I felt toasty.

I have narrow, low volume feet. More so in the heel but also below avg in the forefoot. My feet are also long (about US 12 street shoe). So long, narrow, low volume. I've been professionally fitted for ski boots a few times so I'm sure that's accurate. People are right about the fit on these: they're unbelievably narrow. I was able to get my foot in but I'm not sure I'd be able to get it out if it was swollen at all. For some comparisons, I have the Sportiva Bushido trail shoes, which people say run small and they fit my foot like a glove. Also have Sportvia's Trango TRK GTX boots and those are maybe a little big in the heel but fit the forefoot well. I would have got the Nepal Evo Cube's but needed something warmer as my feet run really cold. So obviously wasn't able to test them out but they look good. There is a little tuxedo vibe to them I see that. But they seem like they're pretty well built. If you have an unusually narrow / long foot, these might be worth checking out. For sizing, I wear a 12 Nike sneaker (11.5-12 in most street shoes), my Sportiva Bushido's are 12.5, my Sportiva Trangos are 11.5. Length-wise I bought these Acrux in 12.5 and that may have been a half size too long although I didn't spend a ton of time with them. If width was ok I would have probably bought a 12 and 12.5 to see which would fit best.

These are beautiful boots which seem well thought-out; I wanted them to work. Like other reviewers, however, I found them extremely narrow. I am a tall woman who wears a women's 10 or men's 9-9.5 boots in normal width. I ordered a whole size up in these based on other reviews. They ended up being too long for me while still being too narrow, especially squeezing me mid-foot. as if they were designed for practitioners of foot-binding or to keep ones bananas from freezing at 6000 meters. To be fair, I do not fit Scarpa boots for the same reason. My feet measure 9.5 inches in circumference at the arch point, 10 inches long from big toe to heel. Maybe I wear a wide...though I do not have this problem in Boreal, Mammut (which is almost too wide for me), Kayland or Lowa. I recommend this boot only for people who know they're feet are narrow, who usually swim laterally in other brands.

These boots were insanely tight. The liners also don't have any means of loosening so they were nearly impossible to put on. With the right fit in length, the width was way too small. You'd have to have weird shaped narrow feet for these boots to work.

I have waited for multiple uses to properly write a review. Many critics stated that they are for narrow feet. I dont normally have super narrow feet, so I am shocked that these arguments are there. Def dont ignore it so try em on but they are snug and amazing. The liner makes this feel like an extension of your foot. Hiked, ice climbed, and maneuvered technical climbs all in one day without any blisters. The vibram sole is bomber. The outer layer keeps feet dry in full on creek crossing submersion. Just like ice climbing you heal doesnt move for some sharp edges. I did puncture the outer layer with a stray crampon but that was me being weak, tired and an idiot. One thing to note. Your feet will get stinky cause the heat gets soaked up in the liner. I didnt find my socks wet, but i found them stinky as all hell. To be fair from some rented Sportivas I have tried. I am ok with this trade off. On a non-technical note..... DAMN THESE BOOTS LOOK GOOD.... I got a lot of comments on em.

I'm confirming all the positive aspects of this boot. However, this is the first rigid double boot I've owned. Many reviewers mentioned it is narrow; or rather fits a narrower foot. My foot is slightly narrow, so based on reviews, I bought a full size larger (11.5) than street shoe (10.5) and this worked excellent. It is still very snug on the side, gives ample room for toes, and room for an extra thick sock, or 2 pairs of medium weight socks. I can cinch the laces, and Velcro strap and have secure heel without movement. I bought these 2 weeks before two ascents in Ecuador: Cayambe - 18,900 and Chimborazo --20,200; 6 hour and 8 hour ascents. Excellent control and moderate weight of the boots was appreciated. I wore liner and one medium weight sock. No cold feet at all. It matches a 12 point Cassin Crampon (Alpinist Pro) very nice for an aggressive response. Love this combination. The zip fastener of the built in gaiter probably contributed to warmth. It was nice feature; so I didn't need to use my external gaiters during the mixed snow/rock/mud conditions, until getting up onto glacier when I put on crampons. I liked. I tried and compared to Scarpa Phantom 6000, and chose ArcTeryx after wearing extensively indoors. I liked the slight extra length, but tight side fit of the Acrux.

Full disclaimer: I'm a huge Arc'teryx fan =) I was looking to upgrade an old pair of mountaineering boots (Scarpa Summit) and saw these and had to try them out. Haven't actually used them yet but for me they fit perfect. Thanks to Travis @ backcountry for his help and input on sizing. Since nobody had them locally sizing is always a hard thing to choose. I ended up using the size chart on Arc'teryx site and I was exactly an 8.5, that's what I ended up ordering and they are perfect! Yes they are narrow but I have small feet, so I could see people with wide feet having issues as seen in other reviews. Perfect amount of stiffness and seem plenty warm. Now to break them in! It's definitely easier to remove the liner when putting them on and taking them off. btw, they fit the new Black Diamond Snaggletooth crampons perfectly.

Love the idea of these boots and the removable liner. But they were too narrow. Someone with a very narrow foot who has trouble finding other boots to fit will probably loves these. I hope they will make them a bit wider.

Considering the weight, these boots are amazing. The liner makes for a great camp bootie and allow for drying at night after a long day. The break in period is a little bit of a longer process that typical. I had to use them for a few trips before the fit felt right. I had some cramping and blistering the first few times out, but after the broke in period, they felt fine. I would say they are true to size length-wise. However, they are a fairly narrow boot, so might not be best for those with wide feet. I've spent several days out in some deep snow, and even some Spring snow that is super wet and have not gotten wet or cold at all. The velcro strap allows for a nice "walk mode" and climb mode. I would say these boots are great for up to 6000 m. One unique tweak to them I'd like to see would be a thinner liner available to use these boots as a single boot too. I would certainly recommend these boots. Feel free to reach directly out to me with any questions on these boots, or any mountaineering questions at all. tbivins@backcountry.com or (801)204-4657

I unfortunately live in an area where mountaineering boots are not sold, so finding the right boot is tough, to say the least. After signing up for an ice climbing trip in Ouray, I realized some new boots might be in order. After hearing great review about the Batura, I purchased a couple of different sizes online but they just didn't seem to fit, mostly due to heel slippage. So I decided to give the new Acrux boots a shot. They arrived 2 days before my trip and seemed to fit very well so I brought them along. These boots were seriously warm for the weight of them, even while standing around in Colorado in December while belaying. They are waterproof on the outside with a zip up system that is bomber. The double boot system is very easy and being able to pull the liner out at night to dry the boots is great. While the lacing system may not be as advanced as the Batura, there is a velcro strap at the top which makes tightening a cinch. The only real issue I had is I felt some slight cramping in my feet which may be because of my low arches, so I took the liner out which fixed the problem, I think i'll look into a flat insole. I definitely recommend these due to the weight and quality of the materials. Everyone was very interested in how they performed and the only negative feedback someone gave is that they looked too much like they should be worn with a tuxedo. I'll take it.

I've been hiking/climbing/paddling seriously since 1977, and I've owned a "few" pairs of boots during that time. Needing a new pair of mountaineering boots for a winter trip to Colorado, I decided to take a chance on the new Acrux-something I NEVER do, that is buy a newly released product before many others have tried it out. And that holds doubly true for something that is life safety dependent such as a harness, rope, or mountaineering boot. I was absolutely elated when I took them out of the box. But my spirits were soon dashed when I tried them on. Too narrow...they fit perfectly otherwise. But in the interest of fairness these were/are the best mountaineering-style boots I've ever had on my feet. Pleasantly light but with a ruggedness you sense rather than see. Quality was typical Arc'teryx-superb. Even the color is pleasant after having been optically assaulted by far too many garishly disgusting hues that clothing, equipment, and footwear manufacturers seem to be enamored with. Unfortunately I purchased the largest size that Arc'teryx makes (in this product) so I'm out of luck and will have to find another brand. I own 10-12 articles of Arc'teryx clothing and XXL fits me perfectly. But that means layering is a chore unless I take time to mix and match "fit classes" such as expedition fit, next to skin, etc. If the company wants to continue to grow they're going to have to produce clothing for adults. I'm a weightlifter and obviously a bit larger than normal but all the stats I've seen suggests that people are getting bigger and Arc'teryx needs to keep up. For this boot, a US 13 wide would work with a US 14 being as close to perfect as can be achieved with a liner sock and Smartwool's Mountaineering Extra Heavy Crew sock. Come on Arc'teryx...get on the ball! I volunteer to beta test a pair and I won't charge you anything!
