Procline Carbon Lite Boot

A true hybrid of the vertical world, the Arc'teryx Procline Carbon Lite Boot combines the climbability of traditional mountaineering boots with the skiability of alpine touring boots. Known for its specialized designs and game-changing innovations, it's no surprise that Arc'teryx's first ski boot isn't just some rehash of popular designs, but an entirely new direction in which to design and build ski boots. At first glance, it's clear that the Procline isn't your standard AT boot—its split cuff, inner gaiter, and unique toe shape all indicate that this boot will dominate technical ascents, whether that be via skins or crampons. Once released into walk mode, the split cuff offers 360 degrees of cuff rotation, with 75 degrees of fore and aft of range of motion and 35 degrees of lateral movement, for unsurpassed mobility while climbing and skinning.

The construction of the Procline consists of a Grilamid shell more akin to a traditional AT boot to give the boot the solid downhill performance necessary for technical ski mountaineering descents and a lightweight split carbon cuff to save weight and enhance climbing mobility. Once locked into ski mode, the cuff remains rigid while skiing. Where the Procline really sets itself apart, though, is with its integrated corder gaiter, which is durable and waterproof to ensure reliable coverage in high alpine environs. Beneath the attached gaiter is a heat-moldable EVA liner with optional lace closure to ensure a precise and comfortable fit. The buckle system of the Procline consists of two aluminum latches and a cam-locking power strap that can be quickly secured without having to fiddle with traditional hook-and-loop straps during transitions.

  • An AT boot built specifically for ski mountaineering
  • Split carbon cuff offers 360 degrees of articulation
  • Attached corder gaiter resists wear and is waterproof
  • Procline Lite liner is heat moldable for a precise fit
  • Two adjustable buckles lie flat to reduce catching on pants
  • Cam-locking power strap ensures a quick and secure fit
  • Lugged Vibram sole climbs well on rock and packed snow
  • TPU toe cap enhances durability when climbing rock and ice

Narrow, difficult to customize

  • Familiarity: I returned this product before using it

I bought this boot imagining it would be a good boot for alpine mixed terrain with serious ski approaches. What I had in mind was something like mixed faces in the mont blanc range (e.g. the Ginat on Les Droites). The liner seems a bit light for that, but otherwise the boots are a cool concept and design. I hope to see more along these lines in the future, because right now there's no real cross over ski/mountaineering boot aside from the procline.

Unfortunately, some of the features work against the boot by making it difficult to customize the fit. My foot is on the slightly wide side (D/E) and several parts of this boot would have needed to be punched/stretched to make this boot work for me with the stock liner (and a thicker liner wouldn't work at all). Unfortunately, because of the design features like the rubber toe cap and the integrated gaiter, my boot fitter was uncomfortable modifying this boot, despite being one of the more experienced and reputable boot fitters in the area (front range of Colorado). I begrudgingly returned these boots, but if it can't be made to fit, that's a nonstarter.

If you're looking at this boot, just hope it fits well out of the box, and you can move fast enough to keep your feet warm while climbing with the thin liner.

I wanted sooo bad to love them!

  • Familiarity: I've put it through the wringer

Overall great idea. I loved everything about them once I had the liners molded, but the rotating cuff wore through the built in gator on both boots and on both sides of each boot. 4 big gaping holes within a few weeks of use (noticeable wear at infected area within a few days)?? Not cool for 1k boots. Waiting to see what the remedy will be, either fixed or replaced? Maybe it was a rare set of lemons? I can only hope!

John, thank you for posting the review. We tested the boots extensively with our athlete team and had zero issues with the gaiters. I've skied a pair for two full seasons with no issues.

Please reach out to our warranty team directly so we're able to examine your boots:


I've had the seame issue as you. Wore clean through the upper/vamp. Arcteryx denied my warranty claim. What happened with your claim?

Great lightweight boot

  • Familiarity: I've used it several times

I am really happy that this boot works as well as it does because I bought it, heat molded it and went straight into a four day hut trip hoping for the best. I usually wear a 28.5 and that's what I bought and I felt like it fit true to size, the toe box is roomy which is something I like and everything else felt snug. The one thing I would say about the lite liner is it heat molds well but it doesn't feel like there is much there and it seems like it could pack out or wear out easy, time will tell on that. The gaiter is cool but I'm wondering how it will hold up, it feels thinner and lighter than the gaiter on my scarpa phantom guide boots and the most annoying thing about the Arc'teryx boots is getting into them and lacing up the liner and then zipping up the gaiter. It is a task.
As far as skiing goes they are great, just stiff enough with a little progressive flex and they drove my voile V8 skis well. Uphill is a dream and the split cuff brings a subtle change that took some getting used to but after I figured out what was going on I liked it. The only reason I give it 4 stars instead of 5 is I need to see how durable they are over time. I would recommend them so far though.

Versatile Game Changer

  • Familiarity: I've used it once or twice and have initial impressions

Arc'teryx does not engineer anything half throttle, and with their expansion into footwear and now ski boots the Procline is no exception. I had a chance to test these last season with our Arc'teryx rep and a couple others at Solitude Mountain Resort out here in Utah. I typically wear a size 28/28.5 in most AT boots and that is what fit me best in the Procline. I have a wider forefoot (I prefer a 102 mm last) and this boot was surprisingly comfortable right out of the box. We did some simple tests in the parking lot to test the range of motion including some step cutting into a large snowbank just to get a feel for the boots.

Skiing conditions that day were hardpack with a slight dusting of new snow and I skied the Blizzard Zero-G 95 Skis (Item #BLZ002C) with Dynafit Radical ST Bindings (Item #DNF003I). The first thing that caught my attention was the power I was able to generate in what was supposed to be a lightweight ski mountaineering boot. I was skiing the stiffest combination of shell + liner and that definitely allowed me to ski the way I like to ski. I briefly tested the tour mode outside the backcountry access gate in Honeycomb Canyon while we also checked out the new Arc'teryx Voltair 30L Backpack (Item #ARC00O5). I hope to get back in these boots again this season on a longer tour or ski mountaineering adventure but first we need snow out here in Utah!.

Don't think of the Procline's as simple AT boots, they are much more versatile that that and could be your one-boot quiver if you are looking for a capable ski mountaineering boot. Feel free to shoot me any questions on this boot or any other ski gear.

Pray for snow!
