    In case you haven’t noticed, AT split boarding is all the rage right now. Binding manufactures have taken note and now offer innovative solutions to meet the AT splitboarders needs. For many riders the last and most elusive piece of the AT puzzle is which AT boots to use. There was quite a buzz last season when photos were leaked of the new Arcteryx Procline AT boots. With little information out there for splitboarders, we reached out to G3/ARC’TERYX rider and ACMG Guide Joey Vosburgh, to hear what he thinks about the Procline boots, and the mods which he made for them. 

    All modifications shown in attached photos were done and ridden by me at my own risk. Arc’teryx is not affiliated with my mods or recommending any boot modification. Any modifications to the boots will also void the warranty. Please remember that doing any of these mods and riding the Procline on Phantoms is done at your own risk. The following photos will help keep your boots in your bindings and your slashes surfy.screen-shot-2016-11-30-at-7-45-58-pm

    Walking and climbing

    This boot walks and climbs considerably better than the TLT6. Which is saying a lot as the TLT6’s are amazing at walking. The cuff articulation is friction free on the procline so it feels very free to skin in. It fits snug even when the buckles are loosened off. The walk/ski lever isnt connected to the top buckle so you have more options for how tight upper buckles can be while skinning. I climbed a M6 drytool route in them and they were fine.

    Binding to Boot

    At first glance I noticed that the toe welt was shorter than other boots I’ve used for splitboarding. I was hesitant because having a foot blow out of a snowboard is terrible and can easily end in injury. With special attention paid towards the setup of the binding and boot I was able to come up with something that has seems to work great for me. The plastic set screw on the Phantom toe lever needs to be at its max and probably glued in so you don’t loose it. See pics. It puts the toe lever at a more positive position to stay locked on the small welt. Tension of the binding is important too. Tight so its secure but not so tight that you need two hands to release binding. Be meticulous with setting that up.

    Boot Flex Modifications

    These mods were done to increase the forward flex in the boot while in shred mode. There is probably other ways to accomplish the same or even better results. This is just what I did. It really made the boot shred better. I wont go too deep into it as I’ve noticed that everyone riding hardshell splitboard boots has a personal preference to modifications. Check out the pics and get some ideas if your the tinkerer type.

    @jvosburgh Any issues using crampons with front bails given the lower profile of the toe welt on the Procline? Many thanks for your write-up and videos! Keep on shredding.

    Thanks for the great write up! Seems it is possible to overcome the small welt.

    I also recently saw the new grivel ski tour. crampons.
    The low profile front bails look like they might provide a closer fit. Not sure if it would be possible to order just the bails from grivel and retrofit them to phantoms but could be worth a shot.

    interesting you went for the carbon model? Have you tried the regular one as well and if so what made you choose carbon? I would’ve thought the regular would offer a bit more lateral flex?

    have still to see a pair in the flesh but comparing the front bail with something like the sportiva Nepal – also small and “recessed” it looks like plenty of ledge to get a wire on.

    Have bankrupted myself with instructor courses this year but looks like I might finally have a hardboot option next year! Hooray! First tour of the season on fitwells the other day was a reminder of how much better life could be.

    yeah, thanks a lot for this post! Nice idea for the mod, I hope I can try this out myself this winter. Gives me some hope after seeing this boot in the store and trying it with my phantoms, which was quite disappointing as I was not aware of the use of the plastic screw before…

    @96avs01 no issues at all. I actually went drytooling a few weeks ago in them and climbed M6 in them. The toe welt easily supports a crampon.

    @kahtiryan I have the carbons because I got them last year and they were the only ones available for me. I too think the lite would be even better. The phantoms lock on the welt fine. No need to mod or add anything for that.

    Now get out there and shred!

    I tested the non-carbon version in a shop. This is a super sweet boot, but I am concerned that there is very little lateral flex. It’s decidedly less than the TLT5. Forward flex is less as well, but it’s not too bad..
    The vertical carbon piece that articulates on the ankle from that pic is what gives the boot all it’s lateral rigidity. It’s plastic on the normal model –×600.png
    I would be very nervous modifying it…

    I wanted to compare it with the TLT6 but they had it only 25.5. Plenty of TLT7s. Too bad they won’t work for us, unless John comes up with a tech Phantoms 😀

    I ride them since today and Im very happy with them. They are much more comfortable than TLTs. I just removed the 4 "noses" and dont need a screw for forward lean as Joey. Bindings have to be a little bit more tight. Maybe they are built for snowboarding not for skiing 😉

    I finally got to have a look at some proclines in person today! They look really nice. Didn’t get to try on but hand flexed and had a play about with the locking mech. The carbon version seems pretty stiff! Would like to see some non carbon ones.

    I’m way too poor to actually be buying a pair anytime soon but had a thought about modding them:

    If you added a bit of elasticity to the cable that locks them into ride mode (eg a couple of small but stiff springs at the ends before the rivets), wouldn’t this allow a progressive flex in all directions?

    Some may not want that flex rearward but I think that’s exactly what makes soft boots feel different – that slight “cushion” of the back of the boot taking the load until you hit the highback (unless you ride with loads of forward lean) Personally I have my highbacks set to zero, like that small bit of give and feel over reliance on highbacks is a major cause of many people’s problems with grip on heelside turns (learn to push through the heels!!).
    Seems @buell is after something similar with the gignouxs. The progressive forward flex on them definitely sounds like the future!

    Anyway just a thought…

    On the Gignouxs, I am after just a bit of cushion on the heel side. I am not looking for any significant travel, certainly nothing compared to the amount of forward flex I want. The thicker liner and slightly softer plastic of the TLTs, and all other AT boots I have ridden, provide plenty of cushion for me. The heelside stop on the Gignouxs is just a bit harsh because of the thin liner combined with the carbon shell.

    This year I switched from Dynafit The One and the first version of Phantoms to fresh 2018 phantoms and Salomon Slab (carbon), which is basically the same boot as the Arc’teryx Procline. I have around 10 days on this setup now and feel I know enough to chip in some comments.

    As one would expect, these are low volume, light boots, and fit as such. The liner is more like a sock than anything else, and undersized at least half a size compared to the shell. Furthermore, even if the liner says it is thermo mouldable, little to nothing actually happens when doing so. With boots like these, doing a proper shell fit becomes even more important. Thankfully, the shell is soft as cheese and super easy to work with for a bootfitter. I have expanded mine some 10-15mm in width (yes, my feet are off the scale wide), and punched out the toe box for both big and little toe too with no issues. The fact the plastic is so easy to work with has allowed me to drop two full mondo sizes, with all the benefits of a shorter sole and lighter weight that comes with that.
    Heel hold is mediocre, mostly due to the liner I suspect. I tried baking a pair of normal volume Intuition Pro Tours, but there just is not enough volume in the shell for them. At some point I will try to get hold of low volume pro tours, but for now they work well enough.

    I chose to open up the holes in the spoiler instead of chopping the tabs on the cuff like Joey did. This way I can go little by little an adjust both “high back angle” and forward flex stop to where I need it to be. Opening the slots to the sides increases medial and lateral flex, to a point. Another reason for going this route instead of the chop is that it will probably be cheaper and easier to replace the spoiler than the carbon cuff, if I ever want to retrace my steps or sell the boots to a skier. My next step will be the phantom boot mod kit, so that I get the buckle to pull more on my heel and less on the top of my foot. On my Dynafits I actually removed the toe buckle and just used the one over the instep, not feeling like I needed more clamping over the foot.
    Oh, and I gaffa-taped a quarter on the toe box where the preload screw of the phantom contacts it to not gouge the plastic unnecessarily. When buckling in, I could actually see the toe box collapsing ever so slightly from the pressure of the screw, and this helps alleviate the issue.

    On the snow:
    Out of the box, forward lean is way too aggressive and borderline unrideable for me, but with a bit of filing they are absolutely sweet. I will try to get some pictures up eventually. Lateral and medial flex is as soft as I could ever want it, I am not sure I would actually have it any softer. The scafo of the boot is really thin and soft plastic, so there is a lot of flexing going on. Compared to the Ones they are a bit less supportive on toe side turns, but I think it has a lot to do with the sorry excuse for a liner that comes with them too. The big intuitions I have in the Ones have a good bit of cushion to them that helps a bit. Plus, the Ones have a tongue and go way higher in the cuff.

    Touring is as expected, just awesome. The floppy lines have next to no resistance in walk mode, the soles are really short and the 3d rotating cuff is actually not bad on slightly off camber skin tracks or when hiking. However, when walking in deep snow the lower buckles open after just a couple of steps, which gets really annoying. I also had problems with the power strap riding up and eventually sitting above the boot and directly on my shin, but a bit of duct tape is enough to keep them in place. Since the cuff moves so freely, I tighten the cuff buckle and the power strap when I start the tour, and don’t have to touch them after that, cutting another valuable seconds from transition times.

    VS Procline
    If you have the choice, go with the Procline I would say. The buckles look better thought out and might have less tendency to unbuckle themselves when bootpacking. The gaiter also looks better and more durable, and maybe, just maybe the liners are slightly less bad.

    And the new version of the Phantoms? It is by far the slickest piece of splitboard equipment I have ever had in my hands, full stop. Everything is an improvement from the old ones, and the workmanship, finish and attention to detail is on another level compared to what else is out there in the market.

    Anyone have more info on these? It looks like they’ve developed a couple more models and included some revisions for next year (increasing welt size, different plastics, etc). Don’t know when the new boots will be out, but with the TLT6’s being discontinued, I’m wondering if these might be the most suitable for our wants now?

    Anyone with any updates on these boots?

    backcountry have the carbon lite boot on sale for $550 and I am seriously thinking of putting some “fruit in my boots”.

    Mine are fubar after about 100 days, all pivot points have tons of slack and the plastic in the lower shell looks like it’s been to hell and back. Not impressed with durability at all. I got a new pair on warranty but put them up for sale immediately and went for Dynafit Speedfits instead.

    The speedfit feels way more burly in the shell, has bigger welts and feel more secure in the phantom bindings. And the buckles don’t open by themselves. Touring is slightly worse since they have a soft plastic tongue instead of no tongue but riding feels better, the flex is more progressive on toe side. Lateral and medial flex feels fine without mods except for the standard filing open of the walk mode lock slot. The fit is way roomier too, I had to do way less work on the shells to get them to fit.

    The Salomon has the same toe welt as last year, but the Arcteryx has a bigger one which looks nice.

    Hi everyone,

    Heres my take on modifying the Proclines ARs. I’ve been doing mods for 2 years now taking it step by step. I’ve found the boot to be stiffer then what I wanted so I kept on experimenting and modifying.

    I started with cutting part of the ‘nose’ on the back of the boot and increasing the hole so as to introduce forward flex. Couldn’t get the desired effect so I shaved boot material from different parts around the cuff.

    Photos and videos over here (hope it works 🙂 )

    The breakthrough came from an idea I came up inspired by @jvosburgh initial mod, or a variation of that mod, maybe someone else has come up with something similar. I chopped off the back ‘nose’ altogether and increased the hole size up to where the cable is installed as well as a little bit on its lowest side.

    I designed and shaped a custom ‘nose’ out of teflon and attached it where the original was (a bit lower) with a screw. The improvised new ‘nose’ is shaped like a ramp offering a gradual friction resistance as the boot flexes forward. This way I Introduced progressive forward flex in the system.

    Another advantage is that you can experiment with different shapes, and a different size or inclination ramp will offer a different feel and result. You can also backtrack and reduce the flex if you’ve overdone it by installing a more burly custom ‘nose’. The forward lean is also adjustable by how much you adjust and shape the back part of the ramp.

    I’m now satisfied with the setup and have the softness and surfy feeling that I was looking for. Lateral flex is satisfying as well, could be a bit better by increasing the length of the lateral cuts I have already done but I’d like to switch to Phantoms so I’ll be a bit patient as I’m expecting to get the small amount missing by them.

    Hope it helps and inspires with future mods for other riders the same way I have found useful this forum.
