Intro
Today, Salomon revealed their newest collection of alpine ski boots, and there’s a lot to discuss.
These new S/Pro Alpha C BOA boots will serve as the brand’s high-performance, low-volume offering for the 2026-2027 model year, with limited quantities of select models available now.
We’ve been spending time in the S/Pro Alpha C BOA 130 and women’s S/Pro Alpha C BOA 115 W, and if you’re a BLISTER+ member or have our Digital Access Pass, you can check out our Flash Review for our initial on-snow impressions.
But as we log more days in these boots, let’s take a look here at their design; what Salomon is claiming about them; and how — on paper — they stand out from the rest of the alpine ski boot category.
What Salomon says about the S/Pro Alpha C BOA
“This is the most direct, progressive, and smooth alpine boot Salomon has ever designed. The evolution of the S/PRO ALPHA C BOA® is all about giving aggressive skiers more power and control without sacrificing comfort. We reworked this boot from the inside out to deliver a high-performance design that responds instinctively on snow thanks to the new ExoDrive and better heel hold, enhanced energy transmission, and a fit that can be dialed in with absolute precision.”
The S/Pro Alpha C BOA Series
Salomon launched this collection with the flagship S/Pro Alpha C BOA 130 & S/Pro Alpha C BOA 115 W, both of which are now available in limited quantities at select retailers and at salomon.com.
The rest of the collection will see its full release later in 2026, and it will consist of eight models (four men’s & four women’s):
- S/Pro Alpha C BOA 130
- S/Pro Alpha C BOA 120
- S/Pro Alpha C BOA 110
- S/Pro Alpha C BOA 100
- S/Pro Alpha C BOA 115 W
- S/Pro Alpha C BOA 105 W
- S/Pro Alpha C BOA 95 W
- S/Pro Alpha C BOA 85 W
Shell Design
This is the big story.
The vast majority of 2-piece alpine ski boots look fairly similar — they have a lower shell that’s connected to an upper cuff at pivot points on either side, typically consisting of a bushing or bearing placed just above the ankle area.
The new S/Pro Alpha C BOA models are an exception.
On the medial side of these boots, their upper cuff extends below the ankle and attaches to the lower shell via a “Powerlink” plate bolted slightly above the boot’s sole. The lateral side of the boot features a more traditional cuff shape and pivot point, but the latter is reportedly a bit lower vs. other Salomon boots.
Inside the shell, you can also see a small cutout in the lower shell (covered by a black textile to keep out snow), which effectively serves as the pivot point on the medial side of the cuff, since it doesn’t have a traditional bearing or bushing there.
According to Salomon, the general idea here is that the S/Pro Alpha C BOA’s lower pivot points and extended cuff equate to better leverage and power transfer from your legs to the edges of your skis.
This shell layout also allowed Salomon to attach the medial part of the instep buckle to the cuff, rather than the lower shell, which they claim further boosts power transfer and makes for a more precise and consistent fit around the ankle and instep, without unwanted foot compression.
Aside from this new shell geometry, other highlights include traditional buckles for the lower shell and a BOA system for the upper cuff. Salomon says they opted for this layout to allow people to independently tighten the lower buckles, while the upper BOA reportedly results in a more consistent fit and more cohesive connection between the upper cuff and lower shell.
The S/Pro Alpha C BOA boots feature PU shell materials that are heat-moldable via Salomon’s “Custom Shell HD” process.
These boots also come with the brand’s “Power Spine,” which allows users to swap between two settings: “Reactive” and “Progressive.” Switching this setting changes the amount of surface area connecting the lower shell to the upper cuff at the back of the spine.
Liner
The flagship S/Pro Alpha C BOA 130 and S/Pro Alpha C BOA 115 W come with Salomon’s new S/Pro CF Expert liner. It’s fully heat-moldable and comes with a new version of the brand’s “Custom Tongue,” which is dismantlable, also adjustable position-wise, and now features an “edgeless” seam finish.
Power Strap
The flagship S/Pro Alpha C BOA 130 and S/Pro Alpha C BOA 115 W feature a high-end, 50mm-wide, elastic power strap that secures via a cam-style buckle closure. The softer models feature more traditional, velcro-style power straps.
Soles
The blue version of the S/Pro Alpha C BOA 130 comes stock with non-rockered “Alpine” soles that fit the ISO 5355 norm, and they are replaceable.
The other models in the S/Pro Alpha C BOA series (including the “Wrought Iron” colorway for the 130) come stock with replaceable GripWalk soles, and you’ll be able to get GripWalk soles for the blue version of the 130 through a Salomon dealer.
Cuff Adjustment
Despite their unconventional cuff layout, the S/Pro Alpha C BOA boots still allow bootfitters to make adjustments to the cuff alignment. The lateral side has conventional adjustability at the pivot point, while the medial side can be adjusted by swapping in aftermarket versions of the “Powerlink” plate.
Weight (and Comparisons)
Our size 26.5 S/Pro Alpha C BOA 130 weighs about 1900 grams per boot, while our size 24.5 S/Pro Alpha C BOA 115 W weighs about 1750 grams per boot.
That puts these boots roughly around the middle of the spectrum for non-touring boots. They’re notably lighter than most boots that feature race-inspired shell constructions, but they’re not the lightest alpine boots on the market.
Here are a number of our measured weights for some comparable boots. For our measured weights, we list the weights of each shell + the weights of each liner, then the total weight of the shells + liners. Please pay attention to the size differences to keep things apples-to-apples.

Fit
As always, we highly, highly recommend trying on boots in person with an experienced bootfitter. Everyone’s foot is different, and fit should be the deciding factor for the vast majority of people in the market for new ski boots. If you’re looking for a good bootfitter in your area or somewhere you’ll be visiting, check out our list of Blister Recommended Shops.
With that said, Salomon calls the S/Pro Alpha C BOA a “low-volume” boot and lists a last width of 98 mm for a size 26.5.
Our editor-in-chief, Jonathan Ellsworth, now has 5 days of skiing in the boot, and here are a few of his initial fit notes:
Jonathan: So far, I’m getting along very well with the fit of this boot — especially with more time in it and the liner naturally molding to my particular feet. Notably:
(1) Toe Box Length: I personally love the length of the toe box, because my feet like a longer toe box.
(2) Heel Pocket: I have fairly narrow heels, and a personal pet peeve is when allegedly “low-volume” boots have heel pockets that feel too roomy. Granted, if you have wider heels than me, you will feel differently, but I want a precise, snug heel pocket, and the Alpha C BOA delivers this: it’s not the tightest heel pocket out there, nor is it the roomiest … and I think it will work well for a number of folks accustomed to skiing in ‘LV’ boots.
(3) Instep Height: The Alpha C BOA actually has some height here, which, for my high arches, is much appreciated. For people with really low arches / flat feet (i.e. your feet are shaped like the letter “L”?), I can imagine that you might find the instep to be too roomy … but that’s not me.
(4) Mid-Foot Width: Snug. This, for me, was where I felt the most pressure from the boot, and it was pretty intense the first few days skiing. I also think this is a good thing, because again, this is supposed to be a low-volume boot, and the more time I get in this boot, the more the liner is molding to my particular feet, and that pressure has moved from “quite intense” to the high-performance-snug fit that I want.
Two things to sum up:
(1) When it comes to fit, I think this is an excellent take on a “low-volume” boot. Other companies will have shorter toe boxes, lower toe boxes, narrower toe boxes, lower instep heights, etc. And such boots might offer a better fit for some “LV” skiers. But I will wager that more “LV” skiers will be very happy with the fit of the Alpha C BOA.
(2) I have not done a direct fit test between the previous iteration of the S/Pro Alpha boot and this new boot. But my recollection is that the fit of these two boots is very similar. Everything (or virtually everything) I’ve just said about the Alpha C BOA is how I remember the fit of the previous (non-BOA) version of this boot.
Bottom Line (For Now)
Most of the time, when we get word of a new ski boot, it doesn’t look like a dramatic departure from what we’ve seen before.
Salomon’s new S/Pro Alpha C BOA collection is an exception. Salomon has tried something pretty different with these boots, promising notably better power transfer and a more consistent fit via their unconventional shell layout.
We’ve already started A/B testing them against other boots to figure out what all of this actually translates to on snow, and you can read our initial impressions in our Flash Review linked below.
