Scarpa 4-Quattro XT Alpine Touring Boot
The Scarpa 4-Quattro XT is a 1,500-gram (size 27) freeride hybrid boot with a 100 mm last, a 130 flex, and a GripWalk (ISO 23223) sole with tech inserts, built for skiers who want alpine-boot power and a real walk mode in one boot. Developed with Bode Miller, the 4-Quattro XT pairs a four-buckle overlap shell with 61 degrees of cuff rotation, so it drives skis inbounds and still tours efficiently on the way up.

Why We Like It
- At 1,500 g per boot (size 27), the 4-Quattro XT skis like a resort boot while still touring with a 61-degree range of motion, a rare balance in a four-buckle hybrid.
- The 130 flex is real. We find the Grilamid Bio shell and overlap cuff deliver a firm, supportive flex that holds up driving skis inbounds and in variable snow.
- The GripWalk (ISO 23223) Presa sole with tech inserts lets one boot move between GripWalk alpine bindings and pin-tech touring bindings, which is the reason many skiers buy it.
- The low stand height sits the foot close to the ski for quick, direct edge engagement.
- The four-buckle closure with a Booster power strap wraps the low-volume shell securely and drives power to the ski.
- The Intuition 4PRO Flex XT 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
- Freeride and sidecountry laps that mix lift access with short skins
- Aggressive skiing on skis 90 to 110 mm underfoot
- Skiers with narrow, low-volume, low-instep feet
- 50/50 skiers who want GripWalk and pin-tech compatibility in one boot
Bootfitter's Advice
The 4-Quattro XT is one of the lower-volume boots we fit, running narrow through the midfoot with a notably low instep. After fitting these to many skiers, we find they suit narrow, flat, low-volume feet best, and skiers coming from a voluminous boot like the old Scarpa Freedom or Maestrale 3.0 will notice much less room. Confirm size with a shell fit rather than converting from a street-shoe number.
We can punch the Grilamid Bio forefoot across the metatarsals and at the fifth-toe area, which the shell takes well, but the low instep is hard 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 XT liner to lock in heel hold, and many skiers swap to a wrap-style liner for longer tours.

Compare the Scarpa 4-Quattro XT
4-Quattro XT vs. Scarpa 4-Quattro Pro
The Scarpa 4-Quattro Pro shares the XT lower shell and low-volume fit but reinforces the cuff, upgrades to the Secure SpeedLock 4 walk mechanism, and states a 130-plus flex for the most aggressive skiers. The 4-Quattro XT is the slightly lighter, more affordable four-buckle 130 that still tours with the same 61-degree range of motion.
Shop Scarpa 4-Quattro Pro boots4-Quattro XT vs. Scarpa 4-Quattro SL
The Scarpa 4-Quattro SL uses a softer Pebax Rnew shell for a 120 flex on the same 100 mm last, while the 4-Quattro XT runs a stiffer Grilamid Bio shell for a firmer 130. Skiers who want maximum downhill power choose the XT, while lighter skiers or those wanting a more forgiving flex often prefer the SL.

Skiers cross-shop these two as 130-flex boots that ski inbounds and tour. The Atomic Hawx Ultra XTD 130 BOA is a 98 mm-last alpine-touring boot with a BOA forefoot and a GripWalk sole, while the Scarpa 4-Quattro XT tours with a longer 61-degree range of motion and adds a low stand height for a more direct feel. Foot shape and how much you tour usually decide it.
