Scarpa 4-Quattro GT Ski Boots, size 29 review: specs, sizing and what it costs you
The Scarpa 4-Quattro GT Ski Boots, size 29 sits in the under-$1,000 budget tier. Published specifications: Type Freeride touring, Cuff rotation Wide, walk mode, Sole Rockered, tech fittings. Best for: A tourer who also skis the descent hard, on a wide touring ski.
The Scarpa 4-Quattro GT Ski Boots, size 29 is a touring boot in the under-$1,000 budget tier, and this page is the short version of everything published about it: the manufacturer's own specifications, who it suits, what it gives up against the alternatives, and where it sits on the shelf it competes on. We have not skied this item and we do not pretend to have. Everything below is researched from published specifications, published certification standards and verified owner reviews.
A boot built from the touring side rather than the resort side, and the difference is the cuff: it actually rotates, which is what stops a long climb feeling like walking in a cast.
A touring boot is judged on cuff rotation first and stiffness second, which is the reverse of an alpine boot. Sixty degrees of free rotation on the climb is the difference between walking and hobbling, and every boot that adds downhill stiffness takes some of it away.
Published specifications
These are the manufacturer's figures, not measurements we took. Specifications change between model years and between sizes, and a listing tied to one size is exactly that, so confirm the numbers on the retailer page for the size you are actually buying before you commit.

Who it suits
A tourer who also skis the descent hard, on a wide touring ski.
What it costs you
Not as damp as a dedicated alpine boot on hard resort snow, and it costs more.
That trade is worth stating plainly because it is the thing a product page will never tell you. Nothing in snow sports is free: every gram removed from a ski comes out of its damping, every degree of cuff rotation added to a boot comes out of its downhill stiffness, and every dollar saved on a shell comes out of either the fabric or the features. The question is never whether an item has a weakness, it is whether that particular weakness lands on the days you actually ski.
The limitation: a fifty-fifty boot is beaten at both ends by a boot that only does one job
This boot is a genuine compromise and the compromise is the product. Against a dedicated alpine boot on hard resort snow it is less damp, because a touring shell has less plastic in it and a walk mechanism is a hinge in the spine of the boot. Against a dedicated touring boot on a long climb it is heavier with less cuff rotation. It is very good at being both. It is not better than either at being one, and if your season is genuinely lopsided the specialist boot is the better purchase.
Second, the sole. Rockered soles with tech fittings are not accepted by every alpine binding, and a boot and binding that are not designed for each other is a release problem rather than a fitting inconvenience. Confirm the combination with a technician who has both in front of them, and have the release value set on a jig at the same time. That is a shop job in every case, not a specification you read off a page.
Third, warmth and fit. Touring shells run thinner than alpine shells and touring liners run lighter, so a fifty-fifty boot is generally cooler on a chairlift than a dedicated resort boot at the same price. And this is a Scarpa fit, which suits a lot of feet and does not suit all of them. Last width is not adjustable, so the shell shape is the first thing to check and the ski boot fitting guide is the thing to read before you spend seven hundred dollars.

Prices are what the retailer listed when this page was last checked and change constantly. We earn commissions from Backcountry and from qualifying Amazon purchases, and every outbound link in this table is one or the other. A button reading "BC category" opens a Backcountry search for that category rather than that exact model, so it finds comparable gear alongside it.
What owners consistently report
Nobody here has skied this item. What follows is the consensus of published owner reviews across retailers, summarised rather than quoted, with no invented owners and no invented quotes attributed to anybody.
Published owner reviews are consistent that the walk mode is real rather than a marketing feature, which is the difference between this and a resort boot with a token hike switch. Owners report climbing comfortably in it and then skiing the descent harder than they expected to be able to, and the tech fittings mean it works on a proper touring binding rather than only on a frame binding.
The recurring complaints are weight on long climbs, warmth on cold chairlift days, and price against the dedicated alpine boots it sits beside. A pattern in reviews is buyers who tour more than they expected to and move to a lighter boot within a season or two, and buyers who tour less than they expected and wish they had bought a resort boot and rented for the tours.
Alternatives worth comparing
Scarpa Maestrale RS Ski Boots, size 29 Under $1,000
The dedicated touring version of the same idea, with about sixty degrees of published cuff rotation and less weight to lift. It costs two hundred dollars more and gives up downhill support, so it earns its place only if the climbing is genuinely the point of your days.
Fischer Ranger HV 120 DYN Mens Boots, 29.5 mondo Under $1,000
A high volume shell for wide feet with tech fittings and a walk mode, about a hundred and eighty dollars cheaper. It is heavier with less cuff motion, so long climbs are harder work, but for a resort-first skier with a wide foot it is the better shape and the better value.
Atomic Hawx Magna 110 S Mens Ski Boots, 27/27.5 mondo Under $500
A stiff alpine boot on a wide last for a good deal less money. If the honest count is a handful of tours a year, a proper resort boot plus rented touring boots on those days skis better on the thirty days that are not tours.
Every alternative here is a product already verified on this site, so the listing behind each link resolved live through CreatorsAPI and the returned title was read against the product the entry claims to be. Both buttons are affiliate links, and prices move constantly.
How to shop this category
A touring boot is judged on cuff rotation first and stiffness second, which is the reverse of an alpine boot. Published rotation is how far the upper cuff swings when the walk mode is open, and it ranges from roughly 40 degrees on a heavy freeride touring boot to over 70 on a race boot. On a three thousand foot climb that difference is felt in the hip flexors within the first hour, and it is the single specification that separates walking from hobbling.
Everything that makes a boot ski better downhill takes rotation away: more overlap in the shell, more plastic, a stiffer spine, a beefier walk mechanism. That is the trade, and the honest question is what fraction of your days are spent climbing. A 50-50 skier who tours in the morning and skis the resort in the afternoon wants a heavier hybrid boot with alpine or GripWalk soles alongside tech fittings. A dedicated tourer wants a light boot with a huge range of motion and accepts that it skis softly.
Weight matters here the same way it matters on a ski, and it matters more, because weight on the foot costs disproportionately more energy than weight on the back. Compatibility is the other checklist item: confirm the boot has tech fittings at both toe and heel, and confirm the sole standard against whatever binding you plan to use it in, because a touring sole in an alpine binding not certified for it is a release problem rather than a convenience one.
Cuff rotation is the number that decides a touring boot
Published cuff rotation is how far the upper cuff swings when the walk mode is open, and it ranges from about 40 degrees on a heavy freeride touring boot to over 70 on a race boot. On a three thousand foot climb the difference is felt in the hip flexors within the first hour. Everything that makes a boot ski better downhill, more overlap, more plastic, a stiffer spine, takes some of that rotation away, which is why the honest question is what fraction of your days are spent climbing.
The three mistakes this category produces
Shopping on flex index and ignoring cuff rotation
Rotation is what you feel for hours. Flex is what you feel for minutes. Look up the published rotation figure before anything else.
Buying a light race boot for 50-50 use
A sub-1,000 gram boot climbs beautifully and skis softly. If half your days are inbounds, buy the weight back deliberately.
Assuming a touring sole works in any binding
Rockered touring soles are not certified for every alpine binding. Check the sole standard and let a shop confirm the pairing before skiing it.
Looking after it
Dry the liners after every tour and keep the tech fittings clean, because packed ice in the toe sockets is how a toe piece fails to lock. Walking on rock wears the toe inserts, which is a real failure mode, so keep bootpacking on rock to what the day requires. Check the walk-mode mechanism for grit at the start of the season and keep it free of ice on the hill.
None of that is glamorous and all of it is cheaper than replacing the item. The pattern across every category on this site is the same: snow sports equipment is destroyed by water, heat and neglect far more often than by use, and the difference between gear that lasts three seasons and gear that lasts ten is almost entirely what happens to it in the twenty minutes after you get home.
Which build this appears in
This item is a line in one of the complete build ladders on this site, which means it has been costed against everything else you would buy alongside it rather than picked in isolation. That is the useful way to look at any single purchase: what it does to the total.
- The committed touring setup: A dedicated touring ski and boot, better skins, and the safety kit filled out. The setup for someone who now tours more than they ride lifts.
What to read next
If you are still deciding between models, the full touring boots roundup ranks the shelf by tier with the same published specifications used here. If you have not settled on the rest of the kit yet, the first backcountry touring setup budgets a complete setup line by line with a running total, which is a more useful way to spend a budget than optimising one item.
For sizing, the calculators cover ski length, snowboard size, mondopoint boot sizing, skin width and the skier code your shop uses to set a binding. The reference charts hold the same numbers in printable table form, and the comparisons work through the decisions where two reasonable options genuinely pull in different directions.
If this is your first piece of backcountry equipment, read avalanche safety basics and how to get into backcountry skiing before you buy anything else. The order that keeps people alive is training first, then the three minimum items, then practise, then everything on this page.
Frequently asked questions
Who is the Scarpa 4-Quattro GT Ski Boots, size 29 best for?
A tourer who also skis the descent hard, on a wide touring ski.
What are the drawbacks of the Scarpa 4-Quattro GT Ski Boots, size 29?
Not as damp as a dedicated alpine boot on hard resort snow, and it costs more.
Will the 4-Quattro GT work in my alpine bindings?
It has to be confirmed with a technician rather than assumed. A rockered touring sole changes how the boot sits in an alpine binding, and the binding has to be designed and certified for that sole type for the release function to behave as intended. Take the boot and the binding in together, and have the boot sole length entered and the release value tested on a calibrated jig at the same visit.
What mondopoint size do I need?
Mondopoint is the length of your foot in centimetres and it is the only ski boot size measurement that means anything, so measure your foot rather than converting a street size. Then treat that number as the starting point for a fitter, because length is only half the problem: last width decides whether the shell suits your foot at all, and no amount of buckling changes a shell width.
Scarpa 4-Quattro GT vs Scarpa Maestrale RS: which one?
Buy the 4-Quattro GT if your days are split between the resort and the backcountry and you ski the descent hard, because it holds up better on firm inbounds snow and costs less. Buy the Maestrale RS if the climb is the point and you do long days, because it is lighter with more cuff rotation. Both are the same brand fit, so the shell shape question does not change between them.
Is a 120 flex the same across brands?
No, and this is worth being blunt about. Flex index is not a standardised measurement, so a 120 from one maker can feel like a 110 or a 130 from another, and it varies with temperature and liner as well. Use it as a ranking within one brand range and nothing more. Fit, last width and cuff rotation are all more informative numbers than flex when comparing two different makers.
How much cuff rotation do I need in a touring boot?
Around 50 to 60 degrees is a comfortable all-round figure for most tourers. Under about 45 degrees you feel the restriction on any long climb, and over 70 degrees is race and ultralight territory where the boot skis softly in exchange. Published rotation figures are the manufacturer numbers and are comparable enough between brands to shop on.
Can I use touring boots in my resort bindings?
Only if the sole standard is certified for that binding. Many touring boots have rockered soles that are not compatible with a standard alpine binding, though GripWalk and hybrid soles exist for exactly this. Check the sole stamp and have a shop confirm before skiing it.
Are touring boots less comfortable than alpine boots?
Fit is the same problem in both: last width and shell length decide comfort. Touring boots are usually lighter and have thinner liners, which means less padding and a shell fit that matters more, not less. Get them fitted the same way you would an alpine boot.
What is a hybrid or 50-50 boot?
A boot with tech fittings and a genuine walk mode that is stiff enough and soled to work in an alpine or GripWalk binding as well. It weighs more and rotates less than a dedicated touring boot, and it is the correct answer for anyone whose days are genuinely split between the resort and the backcountry.
How we choose: we compare published manufacturer specifications, published certification standards and verified owner reviews across retailers. We do not test equipment in person, and every figure quoted here is the manufacturer's published number unless we say otherwise. This is researched buying guidance and not professional instruction: binding release values are set by a certified technician on a calibrated jig, and avalanche terrain requires formal training and a current regional forecast that no article can replace.
