    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.

    Narrowly Missed Fit

    • Familiarity: I've used it once or twice and have initial impressions
    • Fit: Runs small
    • Size Bought: US 13/UK 12.5

    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!

    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
