The updated SCARPA Maestrale RS is SCARPA's most powerful alpine touring boot, built for expert backcountry skiers who won't give up descent performance for uphill efficiency. A Grilamid® shell and Pebax® Rnew® cuff give a 130 flex that drives hard turns like an alpine boot, and the Speed Lock 4 walk mechanism opens up for long, demanding climbs.

Why skiers choose it

• Expert power: 130 flex from a Grilamid® shell and bio-based Pebax® Rnew® cuff.
• Climbs naturally: Speed Lock 4 walk mode for an unrestricted stride on steep ascents.
• Locked-in hold: Redesigned 4-buckle closure with Booster® Active Power Strap to cut heel lift and maximize power transfer.
• Custom fit: Thermoformable Intuition® Pro Flex Performance liner on a 101 mm last.
• Touring traction: Vibram® Cayman LT outsole (ISO 9523) for AT and tech (TLT) bindings.
