The Scarpa F1 RS White Rainbow Green: Lightweight and Precise for Backcountry Skiers

The Scarpa F1 RS White Rainbow Green is a ski touring boot designed specifically for advanced female skiers who refuse to sacrifice downhill performance for the sake of comfort on the ascent. Weighing 1,210 g for half a pair in size 25, it’s designed for demanding backcountry skiers seeking a true balance between freedom of movement on the ascent and technical control on the descent. Its construction, tailored to the female anatomy and combined with high-tech materials, makes it a reliable tool for challenging backcountry excursions. The tension between ascent and descent is treated here as a central design principle, not as a compromise.

Efficient Ascent: Structural Lightness and Freedom of Movement

The F1 RS Women’s features an Overlap Flow construction, which promotes natural foot flexion while ascending. The Pebax® Rnew® cuff—a material known for its lightness and flexibility at low temperatures—directly contributes to freedom of movement on ascents, without stiffening the boot’s performance during exertion. The FS lever, designed for ski/walk mode, allows you to quickly switch between the two configurations depending on terrain conditions. The tongue, also made of Pebax® Rnew®, follows the foot’s movement without creating pressure points. The 15° ± 2° forward lean optimizes natural posture while moving forward, reducing fatigue on extended ascents.

Controlled Descent: Flex, Power Transfer, and Lockout

On the descent, the Scarpa F1 RS White Rainbow Green features a flex rating of 100, indicating a crisp response and direct energy transfer to the ski. The Grilamid® Fiber Glass LFT® shell—a composite that combines lightness with structural rigidity—ensures precise lateral support without adding weight. The Booster® Power strap reinforces heel lock and improves power transfer, particularly during aggressive turns on hard snow or varied terrain. These combined features allow the boot to meet the technical demands of female skiers navigating unmarked terrain.

Comfort and Fit: Women’s-Specific Liner and Closure System

The Intuition® FS Tour Women’s liner, designed to fit the contours of the female foot, provides a precise, snug fit and consistent support. The 101 mm metatarsal width (last) offers a fit tailored to women’s feet without sacrificing precision in power transfer. The closure is provided by a BOA® H+1 system, which allows for fine, progressive adjustment of tension in just a few seconds, even while wearing gloves. This system prevents localized pressure points and simplifies adjustments in winter conditions. The boot is handcrafted in Asolo, Italy, and complies with PFAS standards.

Binding and Sole Compatibility

The Vibram® FS outsole guarantees reliable traction on mixed terrain, between skied sections and on-foot approaches. The Scarpa F1 RS White Rainbow Green is compatible with tech bindings (AT + TLT) thanks to its integrated tech inserts, making it versatile for activities ranging from ski mountaineering to challenging ski touring.

Weighing 1,210 g per half-pair, with a flex rating of 100 and a design entirely dedicated to advanced backcountry skiers, the Scarpa F1 RS White Rainbow Green stands out as a logical choice for those who practice ski touring or ski mountaineering on demanding terrain. It combines, in a single boot, the lightness needed for long ascents and the precision expected on technical descents.
