Has anyone tried modifying the inner part of the plastic tongue.
I just picked up a pair of the SL’s for a screaming deal, but I’m having the same problem I’ve had with pretty much every touring boot with a plastic tongue, which is I get a painful pinch point on my lower shin, just above the ankle, in the forward end of the walking ROM. Shin just slams into that inner part of the tongue above the hinge. I’m convinced i must have a lower than average ankle flex point
I’m considering “reshaping” the top of the inner part to widen the V and lower the outsides of that v in hopes of alleviating that pain.
Curious if anyone’s done that with these or boots with a similar style of hinging tongue?
SCARPA Quattro Pro Boot
Last year, SCARPA sent shockwaves through the free-touring world with the 4-Quattro XT, their collaboration with Bode Miller, which offered alpine-like performance in an exceedingly tourable platform. With a year of feedback under their belts, SCARPA is back at it with the Quattro Pro, which features reinforced parts for even better skiing and a more durable platform.
Compared to the 4-Quattro XT, SCARPA has reinforced the upper cuff on this iteration, improving durability while simultaneously increasing power transfer. With the use of an improved Secure SpeedLock 4 ski/walk mechanism, you can confidently charge down the steepest in-bounds run or out-of-bounds chute. SCARPA states the flex of the Pro as 130+, which is designed to stand up to the hardest landings and the most powerful skiers. The Pro also comes with a new liner, to match the performance of the new upper cuff.
Many of the usability features that we know and love about the Quattro XT are carried over in the Pro, including the buckle system, booster-style elastic power strap, and GripWalk-compatible sole which allows skiers to split their time between resort and backcountry bindings. If you're looking to huck cliffs in the backcountry in the morning and carve on your frontside skis in the afternoon, look no further than the SCARPA Quattro Pro boot.
- Reinforced cuff and ski/walk mechanism offer increased stiffness and durability.
- Eco-friendly construction with Pebax Rnew makes for a more sustainable boot.
- Aerogel layer beneath the footbed keeps your feet warm and happy.
- Excellent Intuition 4-Pro Flex Ride liner provides warmth, performance, and a custom fit.
- Aggressive 17-degree forward lean is adjustable 2 degrees in either direction to dial in your ride.
- Elastic Booster power straps offer a progressive flex and a secure fit for maximum downhill control and comfort.
- 60-degree range of motion is excellent for a boot with this high level of skiability.
- GripWalk soles allow you to step into your favorite GripWalk-compatible alpine bindings.

Andrew- You might want to try a footbed before reshaping the tongue. If you have a footbed you might try a very small heel lift and see if that helps at all to reposition the foot a little higher in the boot.
Answer this question:
Scarpa’s website notes, “Some skiers may want to downsize up to 1 full Mondo size, depending upon personal preference”. I measure just shy of 27 and the 26.5 liners are a good length fit out of the box. I probably would squeeze into a 26 shell with stock molded liner or low volume wrap…. sans footbed (superfeet winter thin)… though my punch requirements could push the full downsize shell too far and I prefer a decent footbed.
Walks as well as my backland carbon. Has a little more initial flex than a 3-piece cabrillo (Roxa R3 130). I only sometimes prefer the slightly taller and stiffer R3s when I’m on ski + binding setups nearing ~2.5kg+. I’m 174cm 70kg can squat. Had ~50 days on these in the 24/25 season. Half of those in the backcountry. I rarely tour consequence but do ski hard inbounds and could not be happier with performance.
The Pebax bioresin is appreciated – and thankfully punched easily at home to expand my 1st and 6th. I’m running an intuition tour wrap liner because my calves just don’t work well with tongues. Low instep fits me and is the main reason I went with these over the new Zero G Tour Pro. The low stack height works call me a fan. I’m tight on dorsiflexion so lean + Freeraider delta is good even on Moment’s triple camber resort skis I haul up most days.
Only complaint being that, for as little parking lot walking as I do, the heel of the not-user-replaceable sole shows quite a bit of wear.
My first Scarpa buy and I’ll be back.
Bomber boot.

Hi,
I have a 2018 Scarpa Maestrale boot in size 29.5, and I'm planning to upgrade to the 4-Quattro Pro this fall. I’ve noticed that the shell size of the 4-Quattro is already smaller than that of the Maestrale.
I measure at 29.5, and I’ve tried on the 29.5 in the 4-Quattro Pro. It feels a bit too spacious. I have a narrow, low-volume foot and I’m looking for a more performance-oriented fit.
My question is: Should I size down to a 29.0 to get a smaller, tighter fit?

Hi Albert,
That would be a very marginal/personal call! I would want to know how much room you have in the 29 shell in order to give a definitive answer. I'm sure it would be quite tight. It will be 1cm shorter than the 29.5. If you have a two-finger fit in the 29.5, then you could go down to a 29 to get a one-finger fit, which would be good for performance.
Feel free to email us at help@skimo.co for further assistance or to go more in-depth!

Hi, Just got a paire of Quattro Pros and I am so stoked to try them this weekend.
I have two questions:
-where can I find detailed instructions on how to adjust the forward lean?
-Is it ok to tour with them a few times this season before I get the linings thermoformed?

James,
The forward leans is simple to adjust. You just loosen up the two screws holding the Ski/walk lever on, then slide up or down. lining up to the 3 marks to the side of the lever. The boot comes on the center line of 17 degrees.
You can do a liner mold at any time. Will not affect anything to use first.

3 weird questions for you:
1) Does the 30.0 have a noticeably taller cuff height than the 29.0 size?
2) If yes, does it increase in cuff diameter too? Or just height?
3) Does the Quattro Pro have a taller cuff than the comparable size (equal BSLs) of the new Maestrale RS? E.g. does the Quattro in a 29.0 have a taller cuff than the Maestrale RS 4.0 in a 28.0?
Asking because I have insanely long shins and skinny calves and am curious about frankenbooting a Quattro Pro cuff + walk mode onto a Maestrale lower clog to get the benefit of the instep buckle and non-grip walk soles, but hopefully also get a taller and more powerful cuff.

Hi Brett,
The 30 and 29 Quattro Pro share a cuff, so it will be identical between those two sizes. You would need the 31 to get the next cuff size up, and it would grow in height as well as a little bit of diameter.
For the Maestrale, the break is on 28/29, and then 29/30. So given that the Maestrale runs one full size large, they appear to parallel each other.
The Quattro Pro cuff is not significantly taller than the Maestrale cuff in the same size. However, it does have a larger surface area in the front supported by the buckles, so I do think it will flex marginally stiffer and more progressively as a result.

Today I skied a pair of Quattro SL at a demo event. I believe I put on a size 28 and it had a 308 BSL. This struck me as shorter than I expected and your site shows that BSL in a 26.5/27. Do you know if all the Quattros have same BSL/mondo dimensions?
3/17/2025
Hi Chris,
We only stock the Women's version of the Quattro SL, up to a 25.5/26.0, so I can't confirm for sure. The boot sole lengths of the SL match up with the Pro and XT up to that size though, so I would think the BSL is the same in the men's version.
The 27.5/28.0 should be 308mm, 26.5/27.0 is 299mm. We've got a chart with all the BSLs here.

Hi, I have a pair of the original pebax Hurricane AT boots, without the walk mode, with the Intuition wrap liners. I have the 28.5/29 shell with bsl 324. How will the fit of the pro compare to the old boot? Thanks
2/3/2025
Hi Paul,
While I don't have a Scarpa Hurricane around to try on and compare, I have a hunch that it was pretty high volume, and the Quattro Pro is one of the lowest-volume boots we sell! That is to say, it will probably be very different. The Quattro is a very low-volume fit over the instep, so it is best for narrower and flat/low volume feet and will not work well for a high instep. It is a snug performance fit!

I also wear an older pair of Scarpa TX Comp NTN tele boots, also 28.5, the older yellow ones with black trim. Definitely less volume than the Hurricane's. How would the fit compare to those?

Hi Paul - I'm not Carlos, but maybe I can help. I have the 4-Quattro Pro in 28. I also own the new Scarpa TX Pro in 28 (and used to have the old TX Comps). I also use the Scarpa F1 LT. The 4-Quattro fits nothing like either of those tele boots or the F1 LT - the Quattro is considerably lower volume. Specifically, it feels much narrower than TX pro (2025) and also (but to a lesser extent) the F1 LT. It also has considerably less volume over the instep. Length feels about the same as the modern Scarpa 27.5/28 shells. I don't know of a Scarpa boot that I have ever worn that compares to this fit. I would definitely try it on in person if possible. I would describe my foot on the upper spectrum of low volume. I did have my boots punched at the 5th metatarsal and it has made a world of difference. As Carlos and others have mentioned, it takes a punch well across the metatarsals. I don't think much can be done about the low volume over the instep - but check with professionals at Skimo. Even with the punch I would still call this a snug performance fit. Boot skis really really well in my opinion and the range of motion in the walk mechanism is fantastic. hope that helps.

How does the fit compare to the Quattro XT? They look like amazing boots, but the XT was very tight in the midfoot.

Hi John,
The fit of the Quattro was not changed between the Quattro Pro and the Quattro XT. Although the Pro may feel slightly different out of the box due to its unique, stiffer liner, the fit of the shell is the same. It is worth noting that these boots take a punch pretty well if you just need a bit more width in a particular area.

In theory, if I ski a Lange XT3 130 LV size 27.5, should I be sizing up to 28.5 in the quattro pro?
11/28/2024
Hi Gassouad, if you're a 27.5 in the Lange I would advice a size 28 in the Quattro Pro, which is a 27.5/28 shell. We generally don't recommend upsizing for extra width or height because it can cause fit and performance issues elsewhere in the boot.
11/29/2024
Yes thanks, my goal is not to upsize for extra room. It's just that the bsl is shorter on the quattro pro?
11/29/2024
BSL is not a reliable indicator of the internal length of a boot! It is just a measurement of the outer sole length and varies a lot between models depending on the toe and heel welt dimensions, the way the manufacturer measures, etc. If a 27.5 Lange fits you, the 28 Quattro would be the closest size. 28.5/29 will be a good bit longer.

This likely belies my ignorance, but are there no 1/2 sizes (or are 1/2 sizes just liner/sole differences)?
I picked up a Atomic Backland XTD Carbon 120 in 26.5 from you all last season and this seems like the perfect boot to fit between that and my Shift Pro 130 AT...

Hey Todd,
There are no half sizes in this boot. There wasn't any liner differences in the half sizes of other models.
This boot would sort of be in the same class as a Shift Pro. I say sort of as because same stiffness, but this boot will hike.

No, not taller. Here is what Scarpa says
" New cuff with rigid structure in the back, and lowered at the front for faster transmission of impulses and energy from skier to ski."
and the new stronger Ski/Walk lever.
