Stop blaming your boots.
It's easy to get cold feet, literally and figuratively, when you're pressure breathing your way through the crux of a sketchy mixed pitch at 4,000 meters, but worrying about your toes is the last thing you want to do when complete focus is required. Arc'teryx's Acrux AR GTX Men's Mountaineering Boot is a seriously waterproof, light, and low-volume piece of alpine footwear that will keep your feet dry and help your head stay focused when things are getting serious a long way from anywhere.
Made to provide a sleek fit that won't bog you down, the Acrux is also drier than a desert thanks to multiple Gore-Tex laminates to keep snow, water, and ice out of your socks, without making your feet sweaty, either. The waterproof zippered gaiter is composed of a three-layer Gore-Tex membrane and treated with a TPU coating for supreme waterproofing, and the removable PE foam liner also has a full-height Gore-Tex membrane for ultimate protection in rugged weather. The liner is perforated to increase breathability, and it's designed to be worn alone as a camp bootie when you're shuffling around the hut or trying to keep your toes warm in your tent.
Inside the outer boot, a lace-up inner shell cinches down snugly over the removable liner to lock your foot comfortably in place, and a hook-and-loop strap closes over the ankle to prevent snow, ice, and spindrift from sneaking into your socks. Arc'teryx also built the Acrux with its tongueless Adaptive Fit design, which hugs your foot without pinching or causing pressure points. The carbon fiber and EVA foam midsole cushion your soles during long days in the alpine, and the TPU toe and heel caps protect your toes and make it easy to step into crampons.

- Q & A
not sure who these will fit
- Familiarity: I returned this product before using it
- Fit: Runs small
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.

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.
Narrowly Missed Fit

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!
Any estimate from arc'teryx on when to expect the next batch of size 13?
I'm going on a 30 day/ 75 mile/ 13 peak trip next summer in the Wind River Range. Would this be a good boot?
Hey Sam - These Acrux AR GTX Mountaineering Boots are really designed for cold-weather mountaineering in ice and snow. You could use them in the Wind River Range but I think they might be a bit overkill. Check out the Arc'teryx Bora2 Mid LTR GTX Hiking Boots (Item #ARC00I0) as a solid alternative. I have been to the Wind River Range many times so feel free to contact me directly with any additional questions.

Can these be punched to gain some width on the forefoot?
Hi Brian, Where the upper of these shoes is a TPU laminate as opposed to a hard PU shell like a ski boot, these boots really can't be punched out to make extra room. As with any shoe, it should loosen up a bit over time though. Please feel free to reach out to me directly if you have any other questions. - Matthew Pizza - Expert Gearhead
