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.

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.
