120-Flex Freeride Hybrid Boot

Scarpa 4-Quattro SL Alpine Touring Boot

The Scarpa 4-Quattro SL is a 1,430-gram (size 27) freeride hybrid boot with a 100 mm last, a 120 flex, and a GripWalk (ISO 23223) sole with tech inserts, built for skiers who want an all-day, do-it-all boot for on and off piste. The 4-Quattro SL shares the low-volume 4-Quattro fit and four-buckle design but uses a Pebax Rnew shell for a slightly softer, more progressive 120 flex than the Grilamid Bio XT, with 61 degrees of cuff rotation for touring.

Is This the Right Boot for You?

Best For
Skiers with low-volume, narrow feet who want one four-buckle boot for resort and backcountry, prefer a progressive 120 flex over a stiff 130, and want GripWalk and pin-tech binding compatibility.
Consider Another Boot If
You have a wide or high-volume foot, a high instep, want the firmest possible 130-flex downhill drive, or you want a dedicated lightweight touring boot, since the 4-Quattro SL is a low-volume, 1,430-gram freeride tool.

Why We Like It

  • At 1,430 g per boot (size 27), the 4-Quattro SL is the lightest of the men's 4-Quattro boots while still skiing a supportive 120 flex.
  • The Pebax Rnew shell gives a more progressive, forgiving flex than the stiffer Grilamid Bio XT, which suits skiers who do not need a full 130.
  • The GripWalk (ISO 23223) Presa sole with tech inserts lets one boot pair with GripWalk alpine bindings, hybrid bindings, and pin-tech touring bindings.
  • The four-buckle closure with a power strap wraps the low-volume shell securely and drives skis on and off piste.
  • The 61-degree range of motion and ski/walk lever tour efficiently for a four-buckle boot.
  • The Intuition 4Pro Flex SL liner is heat-moldable, so we can dial in the snug, low-volume fit.

Best Uses

  • One-boot quiver for resort days with a walk mode plus backcountry touring
  • All-mountain and sidecountry skiing that mixes lift access with skins
  • Skiing on skis 88 to 108 mm underfoot
  • Skiers with narrow, low-volume, low-instep feet who want a progressive flex
  • 50/50 skiers who want GripWalk and pin-tech compatibility in one boot

Bootfitter's Advice

The 4-Quattro SL shares the low-volume, narrow 4-Quattro fit with a low instep, so it suits flat, narrow feet best. After fitting the 4-Quattro line, we find the SL flexes a touch more progressively than the Grilamid XT, which lighter and less aggressive skiers appreciate. Confirm size with a shell fit rather than converting from a street-shoe number.

We can punch the Pebax Rnew forefoot across the metatarsals, which the shell accepts well, but the low instep is the hardest area to gain volume in beyond a firm liner mold. Skiers with a high instep should budget for fit work or look at a higher-volume shell. We recommend molding the Intuition 4Pro Flex SL liner to lock in heel hold.

Compare the Scarpa 4-Quattro SL

4-Quattro SL vs. Scarpa 4-Quattro XT

The Scarpa 4-Quattro XT uses a stiffer Grilamid Bio shell and a Booster power strap for a firmer 130 flex, while the 4-Quattro SL runs a Pebax Rnew shell for a more progressive 120 on the same 100 mm last. Aggressive skiers who want maximum drive choose the XT, while skiers who prefer a smoother, more forgiving flex choose the SL.

4-Quattro SL vs. Scarpa 4-Quattro Pro

The Scarpa 4-Quattro Pro is the stiffest of the line, with a reinforced cuff, a Secure SpeedLock 4 walk mechanism, and a stated 130-plus flex, aimed at the most aggressive skiers. The 4-Quattro SL is the lightest and most progressive at a 120 flex, so it suits skiers who value a smoother flex and lower weight over maximum stiffness.

4-Quattro SL vs. Scarpa Maestrale RS

The Scarpa Maestrale RS is a touring boot with a Vibram Cayman ISO 9523 sole, tuned for efficient touring and quick transitions.

Common Questions

Who should buy the Scarpa 4-Quattro SL?
The Scarpa 4-Quattro SL suits skiers with narrow, low-volume feet who want one four-buckle boot for both the resort and the backcountry, and who prefer a progressive 120 flex over a stiff 130. It skis skis 88 to 108 mm underfoot and tours with 61 degrees of cuff rotation.
How is the 4-Quattro SL different from the 4-Quattro XT?
Both share the same 100 mm last and four-buckle design. The Scarpa 4-Quattro SL uses a softer Pebax Rnew shell for a more progressive 120 flex and is the lighter of the two, while the Scarpa 4-Quattro XT uses a stiffer Grilamid Bio shell and a Booster strap for a firmer 130. Skiers who want a smoother flex pick the SL.
What bindings work with the Scarpa 4-Quattro SL?
The Scarpa 4-Quattro SL has a GripWalk (ISO 23223) Presa sole plus certified tech inserts. It works with GripWalk and MNC alpine bindings, hybrid bindings such as the Salomon Shift and CAST, and pin-tech (low-tech) touring bindings. It is not compatible with standard ISO 5355-only alpine bindings. Confirm any MNC or hybrid pairing against your specific binding.
Is the Scarpa 4-Quattro SL really a 120 flex?
We find the 4-Quattro SL skis close to its stated 120, a touch softer and more progressive than the Grilamid Bio 4-Quattro XT that Scarpa rates at 130. The difference between the two on snow is subtle and can come down to how you buckle them, but the SL is the more forgiving of the pair.
How does the sizing and fit run on the Scarpa 4-Quattro SL?
The 4-Quattro SL is a low-volume, narrow boot with a low instep, and it fits noticeably tighter than older Scarpa boots. Length runs close to true Mondo. We recommend a shell fit rather than converting from a street-shoe size, since the performance fit is snug through the midfoot and instep.
Can the Scarpa 4-Quattro SL be punched and molded?
Yes. We can punch the Pebax Rnew forefoot across the metatarsals, which it accepts well, and the Intuition 4Pro Flex SL liner is heat-moldable. The low instep is the hardest area to gain volume, so skiers with a high instep should plan on fit work or a higher-volume boot.
How well does the Scarpa 4-Quattro SL tour?
For a four-buckle boot the 4-Quattro SL tours very well, with 61 degrees of cuff rotation that is much freer than a typical 50/50 alpine-touring boot. At 1,430 g per boot it is heavier than a dedicated touring boot, so skiers focused on big-vertical days may prefer a lighter option.
What skis pair well with the Scarpa 4-Quattro SL?
The Scarpa 4-Quattro SL drives all-mountain and freeride skis 88 to 108 mm underfoot with confidence. The 120 flex and low stand height reward skiers who want a progressive, direct feel both inbounds and in the backcountry.

Our Verdict

The Scarpa 4-Quattro SL is the most well-rounded of the men's 4-Quattro boots for skiers who want a hybrid that does everything without the firmest possible flex. It skis a progressive 120 on a four-buckle overlap shell, is the lightest of the line at 1,430 g per boot, and tours with 61 degrees of cuff rotation and a GripWalk sole that pairs with alpine, hybrid, and pin-tech bindings. Like the rest of the family it is a low-volume, low-instep boot that rewards narrow feet. For a narrow-footed skier who wants one forgiving boot to ski inbounds and tour, the 4-Quattro SL is a strong choice.
