First Look: Scarpa’s F1 RS

Scarpa’s F1 gets an overhaul and adds the BOA H+1 System.

Scarpa’s new F1 RS features a BOA H+1 Remote System for the lower and a single buckle + cam-lock powerstrap on the upper. The F1 RS will be the stiffest skiing boot in the F1 line.

Feet scorned by ill-fitting touring boots should be a thing of the past. And poor turns or earned-vert scorned due to poor-performing touring boots: too mushy, too stiff, not enough ROM, or too much friction. Human feet come in all sorts of shapes and sizes. As do preferences regarding fit and flex characteristics.

Lucky us, we live in the time of the touring-boot bounty. After a long duration of boot stasis years ago, when mods and shell molds were mandatory, or just a downright pain because a mod or mold didn’t help, we’ve had a big burst of boot evolution. For most of us, there’s a boot out there that will work. Enter Scarpa, the Italian sports brand focused on mountain boots and shoes. In their touring boot lineup alone, I see 18 touring models—including men’s and women’s and the Quattro line, which some folks see as a hybrid boot—to find a boot that suits your needs. Add in Dynafit, La Sportiva, Tecnica, Atomic, Dalbello, and onward, and you see where we’re going. 

But as the title suggests, we’re here for a first look at Scarpa’s F1 RS. As part of our process to learn more about the boot and its development, Gavin and I recently spoke with Scarpa North America CEO Kim Miller, and we’ll have that story edited and posted soon.

The new F1 RS replaces the venerable F1. Over the years, the F1 line expanded to include the F1 LT (BOA), F1 XT, and F1 GT. These boots generally sat in the 1 kg realm in the smaller sizes, and focused on a solid combo of ascent and descent characteristics. For those looking for a more sporty descent performance or to drive burlier skis, ski tourists often bump up to the F1, the Maestrale, or the Gea, respectively.      

But what catches our eye here is likely what caught your eye—the implementation of the BOA H+1 System. I know, some of you might be checking out already. Many of us, yup, we are out here, are BOA fans. And we know the potential pitfalls of BOA’s past (or Dynafit’s Twistfit system)—they might fail, they just don’t tighten properly, and they don’t secure the foot the way a buckle does. I’ve spent several years in either the Fischer Travers Carbon and the Dynafit Blacklight, and I’ve never had a failure or thought that properly securing my foot in the scaffo was an issue. I like buckles fine, and they serve their purpose in the Blacklight 2s and Sportiva Kilos—both use a Z-buckle—but, considering the whole boot package and all things being equal on a boot, I prefer a BOA. 

The F1 RS is one of the first touring boots to integrate the BOA H+1, which is a beefed-up version of the original BOA system found on boots like the Travers, Scarpa F1, and F1 LT. The F1 RS is the first touring boot to secure the BOA dial on the boot cuff, while the cable, when tightened, secures the foot in the lower. This is why Scarpa, in their marketing copy, calls it the “BOA REMOTE DIAL H+1 REMOTE CONFIGURATION.”

This remote system is similar to the H+i1 BOA now found on many alpine boots, but in those configurations, for example, a BOA dial on the cuff secures the upper, while a dial on the scaffo secures the lower. The advantages of the remote system are the positioning of the dial away from a spot on the boot where shearing the BOA dial off while booting may occur, a complaint some have made regarding BOA dial positions in the past. With the F1 RS remote design, although it is a larger, more robust dial, it is positioned on the upper outer side and presumably out of the way of obvious wear-and-tear scenarios. The H+i1 system also uses higher-gauge cable and offers multi-directional micro adjustments. Be warned, this system can offer a lot of closure force.

The F1 RS lower uses what Scarpa calls Overlap Flow Construction. According to Scarpa, “new technology features softer instep panels to facilitate easier entry and more natural walking, and a stiffer lower shell to deliver powerful force transmission and high-performance downhill control.” See photos below. I will state that when tightening the BOA, the cable snakes through the guides, the forefoot plastic subtly closes, and begins to secure the foot in a snug and precise fashion. We might as well mention the liner, which is the usual high-quality Intuition liner found across the Scarpa line. Scarpa calls it the Intuition FS Tour, and it includes a plastic overlay on the shin and forefoot. The shin overlay adds some stiffness, while the forefoot overlay helps disperse the BOA cable’s closure force across the forefoot. 

The F1 RS, per the Scarpa program, uses a high-quality Intuition liner (the Tour FS), which has a plastic-reinforced tongue and a plastic segment over the forefoot.

The boot upper is a Grilamid FG LFT and Pbax Rnew (a bio-based thermoplastic elastomer). In other words, the Grilamid is reinforced with long-strand fiberglass. Scraper claims the material has an “extremely high strength to weight ratio and stiffness values 20% to 30% higher when compared to a short-fiber construction found on most lightweight applications.” The cuff is an overlap design and tightens with the single buckle and cam-lock booster strap. The camlock is a thermoplastic with a button that serves as an effective quick release. Since the cam is not metal, we’ll keep an eye out for long-term durability. So far, even while wearing thick gloves, the button is easy to hit to release tension. The ski/walk throw is spring-loaded. 

Well, it’s a first look and a first tease. That’s the qualifier. But I’ve had several days in the boot. After the first outing, I thought I needed to thermomold the liners. The next day, holy smokes, the liners fit great—so I am holding off on any molding for the time being. For some fit highlights, I usually wear a 2mm EZ heel sock to assist with heel hold. (I’ve used them in every boot the last four years outside of the Zero G Tour Pro with an Espresso Liner, the Scarpa Alien 1.0, and now, this boot.) I wouldn’t say I have a skinny heel, but maybe I do. Out of the box, with a thin Patagonia ski sock, and with either the stock footbed or my blue Superfeet insoles, the heel hold is exceptional. I might say it’s the best heel hold and heel fit I’ve ever experienced.

I also have skinny calves (it’s genetic…). With the buckle, powerstrap, and liner fit, I have no problems locking the boot upper onto my leg. Like the heel fit, the snugness of the boot upper is both comfortable and precise without overcranking the closure system.

The cam lock housing is molded plastic. So far, it functions great.

Scarpa boots are a hit-or-miss fit for me. The Scarpa 4-Quattro SL, with its 100mm last, was a bit too tight over the forefoot, and in a 27, the toe box felt a bit short and a smidge narrow. On the other hand, in the Alien 1.0, a Scarpa skimo boot, in a 27 and stock liner, the 27 length is great—I can tour in these boots all day, even with its 99mm last. Go figure. I’m also in a 27 F1 RS, and the length is about perfect for a performance fit. The last is 101mm in a 27, and so far, the instep height, width, and length feel ideal. If I end up cooking the liners or making any mods, I’ll note it in the review.

The claimed range of motion is 60 degrees. I’d say that is accurate, give or take a few degrees. To access the full ROM, ensure the powerstrap and buckle are properly loosened on the cuff when touring. I’ve tried varying degrees of looseness, and looser, to some extent, seems better. And, you’ll likely loosen the BOA on the lower for a bit more comfort, too, on the ascent. The ROM is better moving forward rather than rearward—at least that is what I am experiencing. The friction is about on par with solid touring boots in this class: it might be a bit better than the Zero G Tour Pro (that’s a four-buckle + powerstrap affair) and higher than the Ridge Pro and Blacklight (both Hoji Lock boots), where the Ridge Pro has a plastic tongue, and the Blacklight is tongueless.

F1 RS Transitions are pretty easy with the BOA, powerstrap, and buckle—at least compared to the ZG Tour Pro. As far as stiffness, Scarpa calls it a 115 flex. The weight with the stock liner is claimed to be 1340g (size 27). My scale says 1350g; call it a scale error. 

The skiing, so far, feels great. Granted, I’ve only used it for a few days and in pretty light powder snow. 

In closing, good on Scarpa for taking a leap and offering a touring boot with the BOA H+i1 system; it feels like a great option.

    Thanks for putting this out there! Excited, but I’m in the other BOA camp, and yeah this is a bit disappointing. I feel like big-BOA is the little brother to big-plastic pushing unneeded products on us. I am one of those, for whatever reason, needs to have things really locked in to feel like a boot is skiing well, but the only BOA boot I’ve tried was the F1 LT. Ended up going to the XT and am so much happier about things. Maybe it’s poor technique and poor foot structure, but it’s not going to change here in the middle of my 5th decade. But I understand that BOA does work for some. Looks like a buckle or Z-cable retrofit might not be too difficult.

    That is promising about that heel hold. How is the instep height?

    1. Jason Albert

      Hey Christian, the instep height is good to great for someone with a “normal” instep. For those with a high instep, I’m unsure how the fit would be; that said, it is roomier (instep-wise) compared to the 4-Quattro SL. For those with low insteps, my take is the BOA could be a great way to reduce some of that volume without creating unnecessary pressure points. The BOA system on this boot, as designed, seems to distribute the pressure when cinched down pretty evenly over the forefoot.

      1. Christian Strachan

        Good info on the instep, thanks! I’m in the low-instep category. The BOA does look more like something you’d see now on inbounds-type boots, do you feel you can crank it down more than, say, an F1 LT? With the outboard positioning of that BOA, I’m hoping your testing includes approaches through scree fields! 😉

        1. Jason Albert

          The cranking: from the positioning and the larger dial/gearing, cranking down is not a problem. So, yes, I do feel like it is easier to get more than sufficient closing force on this BOA relative to the smaller (older school) BOA/Twistfit dial on the F1LT, Travers series, and older Blacklight, etc. It’s like going from pedestrian to industrial strength with this new BOA configuration. Sadly, at least locally, there might be scree to navigate sooner rather than later.

          1. Christian Strachan

            Again, great to know, thanks! What’s the bsl of that 27 you’ve got?

            1. Jason Albert

              The BSL for the 27 F1 RS is 297mm.

        2. Slim

          This is the “alpine boot Boa” really very differnt from the “standard” Boa that’s been on touring boots, bike shoes, and snowboard boots.

          I have it on my alpine boots, and and it cranks down with authority, so I imagine it will have now problem crushing thin touring boot shells and liners.

          The dial also has a safety feature where it will pop off if it gets hit just right, and can just be pushed back on.

          Blister did a review on one of the early releases of alpine Boa boots, accidentally tested this feature and said it worked as advertised.

  2. Kam DH

    Looks pretty darn cool. I have both an F1 GT and a Maestrale RS. I also am not so stoked on the BOA. It seems like it could easily get smashed in a postholing through boulderfield situation, but I guess I try to avoid those when possible!

    I am glad to see it has the same kind of walk mode as the F1 GT/XT with the notch in the throw rather than the opposite one on my Maestrale. The Maestrale is super prone to icing and is always popping out of ski mode at the slightest hint of snow. The F1 GT, on the other hand, is super rock solid.

    This seems like a nice quiver killer option to be honest!

    1. Gavin Hess

      The BOA is significantly more out of the way than any other BOA equipped boot ive used. I imagine it will be safe from postholing, aside from a proper side swipe/overhang sort of thing.

      I’ve had enough issues with buckles opening, breaking, etc post holing in snow with or without boulders that I’m open to the idea that the H+i1 boa could be a strong durability upgrade when properly implemented

      1. Kam DH

        Good to hear, looking forward to more in-depth review.

  3. Whit

    Damn that’s a cool design! The Ridge may have some competition. I’m pro-BOA especially this beefier version that appears to be the same version found on new alpine boots where the dial can get knocked off and easily reattach, so most people’s worries about durability should be moot. It’ll crank down more than enough too but does it unwind enough to make it easy to get on and off?
    I know it’s subjective but how does the flex feel compared to the Ridge and Hoji-lock boots?
    Having a regular toe lug should mean it could be a quiver killer boot since you could use it in hybrid bindings, unlike the Ridge. Also I like how there appears to be more forward lean adjustment without just adding a spoiler.
    Looking forward to full review!

      Also interested in that “flex feel”!

      1. Gavin Hess

        With the caveat that Im planning to have my first day out on the F1RS tomorrow, I’ll throw in my 2 cents here.

        I’d describe the flex as somewhere between the ZGTP and the Ridge. The overall feel and construction is more similar to the Zero G, but it feels a bit softer on the whole (In a good, progressive way, to me). Compared to the ridge, nothing feels as rock solid and play free as far as the upper-lower shell connection; the F1RS seems like it will have similar limitations to just about every non hoji lock boot out there as far as developing slop in the walk-ski mechanism.

        The walking is lower friction than I remember in the zero g, and similar to the ridge. The ROM, similar to the Zero G, is somewhat limited by the height of the lower scaffo and its interaction with the cuff.

        I had been wondering for a few years when Scarpa was going to come up with something to challenge the market dominance of the Zero G; this is certainly that.

        1. cap

          Cheers – how was that first day out? 🙂

          1. Gavin Hess

            A week or so in – really impressed with these. Somewhat similar to the ridge, they feel more soft at the top of the flex than many touring boots that are aiming for downhill skewed performance. I like that.

            The fit seems a little more wide than the alien rs/f1 lt platform, while the instep is medium (and relatively forgiving with the soft plastic and boa). Heel hold is, as Jason said, quite good. Worth noting that my last lightweight Scarpa boot was a sz 29.5/30 Alien RS (that was a little too big), I’m in a 27.5/28 F1 RS and mostly loving it.

    Really interesting boot. Probably need to think harder about the geometry but from first look it seems like the base of the boa being on the cuff means the cable will loosen the harder you push forward into the cuff which seems problematic. Curious for how it will ski with the solid overlap.

    1. Christian Strachan

      I think that cable guide where it comes off the scaffo onto the cuff is pretty close to the pivot point, and if one is flexing forward, the mechanics look like it would possibly either tighten it or keep tension constant. I imagine the engineers and testers worked that bit out. Can’t imagine prototype testing that and immediately addressing it if it were an issue.

      1. Patrick Fink

        I think you’re off on this one. The cable pivot that’s on the upper is forward of the cuff pivot point, so flexing into the tongue of the boot will result in slack in the BOA. My guess is that they have to make this compromise because the two alternatives are bad: 1) BOA knob on the lower– too bulky and prone to damage; 2) BOA pivot rearward of the boot pivot– forward flex results in all weight going into the BOA cable rather than the flex of the boot itself. The only way to resolve this issue would be to put the cable pivot directly over the cuff pivot. Or just don’t use a huge boa…. Thinking about this is very reminiscent of mountain bike suspension geometry and chain stretch.

        1. Gavin Hess

          In practice, I haven’t noticed anything funky with the cuff flex affecting the boa tension, but I’ll try to pay some specific attention to this phenomenon next time I’m out. I think the Boa is close enough to the pivot and the travel relative to the pivot is minimal enough that it isn’t a significant issue.

          I’ve got to say, though the BOA knob looks comically large on the cuff like that, it is one of few boots that I can easily over-do it with instep/lower buckle tension. With other boa’s I often feel like it can be quite effortful to get sufficient tension.

  5. Slim

    Interesting boot. I would have thought that the Alpine Boa and its pulleys was heavier than a Z-cable/buckle, but maybe not. Or they feel it’s worth it for micro adjustability.

    Either way, it’s nice to see more options in the “middle ground” boot category.

  6. leonardthedog

    Maybe I missed it, but what skis have you been pairing with this? Any thoughts on how far you’d go on either end (skinny or wide) with this boot?

    1. Jason Albert

      Hey there, it’s just a first look, but I’ve been on the Moonlight Carbon Cruiser Superlight skis, 114mm underfoot in a 177cm. Note, these are very light skis. Skinny: I can see 90mm underfoot being fine Wide: If and when it snows, I could see a heavier ski (than the Moonlight) like the Atomic Backland 109 being good. I suppose if it ever snows enough, the test would be the Nocta’s (177cm)…they are my heaviest touring ski.

  7. Brett Nicholas

    Great first look. How does to cuff height compare to the ZGPT, ridge, and Quattro (if you have them lying around to compare)? I’m tired of super low cuffs on beefier touring boots. I feel like I’m constantly going to tib/fib myself in the Quattro. Understandable on an ultralight boot but annoying on a beef boot.

  8. Kam DH

    And no gaiter to fall apart unlike the F1 XT/GT/LT too…

  9. Ethan Ayer

    So the shell is Pebax Renew? If so how comfortable are bootfitters with punching that material?
