Scarpa Maestrale RS Alpine Touring Boot
The Scarpa Maestrale RS is a 1,570-gram (size 27) freeride touring boot with a 101 mm last, a 130 flex, and a Vibram Cayman Pro ISO 9523 touring sole, built for expert skiers who want alpine-boot power on the descent and 61 degrees of cuff rotation on the way up. The current Maestrale RS is a full redesign, moving to a four-buckle closure with a Booster Active Power Strap, a Speed Lock 4 walk mechanism, a bi-injection carbon-infused Grilamid shell, and a Pebax Rnew cuff. That construction trades 100 grams of added weight over the previous RS for noticeably more downhill stiffness and drive.

Why We Like It
- The 130 flex is one of the more honest 130s in touring. We find the Maestrale RS skis firm and progressive, closer to a true alpine 130 than most touring boots that claim the number.
- The redesigned four-buckle closure with the Booster Active Power Strap wraps the foot in a uniform, high-tension hold that limits heel lift and drives power to the ski.
- The Speed Lock 4 walk mechanism and 61 degrees of cuff rotation give a long, secure stride on the skin track for a boot this stiff.
- The bi-injection carbon-infused Grilamid shell adds stiffness around the flex zone without the harshness of a full carbon boot, and the Pebax Rnew cuff keeps the flex progressive.
- The 101 mm last runs as a true medium and accepts fit work, so it suits a wide range of feet rather than only narrow ones.
- The Vibram Cayman Pro sole (ISO 9523) with tech inserts grips rocky approaches and pairs with pin-tech touring bindings.
Best Uses
- Freeride touring and ski mountaineering where the descent matters most
- Aggressive skiing on touring skis 90 to 115 mm underfoot
- Big backcountry days that mix long ascents with demanding descents
- Skiers who want one boot to charge in the backcountry and lap the occasional resort day
- Medium-volume feet on a 101 mm last
Bootfitter's Advice
The Maestrale RS fits as a medium-volume boot on a 101 mm last, with a secure heel, a medium instep, and enough forefoot room to suit a broad range of feet. After fitting the Maestrale line for years, we find it runs slightly true-to-snug in length, so confirm size with a shell fit rather than converting from a street-shoe number. Skiers coming off a narrow race-style boot will notice more room, while those on a wide alpine last should still try it on before assuming it is too tight.
We can punch the Grilamid forefoot and the sixth-toe area without much trouble, but we avoid the darker carbon-core zones, which do not modify as forgivingly. Plan on a heat mold for the Intuition Pro Flex Performance liner to lock in heel hold and take pressure off the instep. Skiers with a very high instep or a wide forefoot beyond a medium 101 mm last should budget for fit work or look at a higher-volume shell.

Compare the Scarpa Maestrale RS
Maestrale RS vs. Tecnica Zero G Tour Pro
Both are 130-flex four-buckle touring boots aimed at skiers who want alpine power on the way down. The Scarpa Maestrale RS runs a medium 101 mm last and 61 degrees of cuff rotation, while the Tecnica Zero G Tour Pro uses a narrower 99 mm last and is known for a longer, freer stride, so foot shape often decides between the two.

Skiers cross-shop these two as burly freeride touring boots. The Scarpa Maestrale RS is stiffer at a 130 flex on a 101 mm last, while the Dynafit Radical Pro is a 110-flex boot on a wider last near 103.5 mm, so the Radical Pro suits higher-volume feet and the Maestrale RS suits skiers who want more downhill drive.

The Scarpa Maestrale RS is the stiffer, more downhill-focused sibling at a 130 flex and 1,570 g, while the standard Scarpa Maestrale runs a softer 115 flex at a lighter weight on the same 101 mm last. Skiers who prioritize a lighter uphill often pick the Maestrale, while those who charge hard on the descent choose the Maestrale RS.
