Size Chart

All SCARPA footwear uses Europeansizing, except for the skiing boots.

  •  1 Euro whole size = 6.6 mm = 0.26 inches
  • 1 US whole size = 8.4 mm = 0.33 inches
  • Euro sizes provide a better, more precise fit for your intended use
  • Only Ski mountaineering and telemark skiing boots are in MONDOPOINT size.

Upsize (½ sizes) depending on desired fit for mountaineering boots.

For climbing shoes, the choice of downsizing (1 size) depends on the desired fit. In other shoes, you need a gap between the toes and the front of the toe box, which is necessary for walking. In climbing shoes, it is preferable to eliminate gaps, to increase sensitivity and precision when climbing.

All SCARPA's ski mountaineering and telemark skiing boots ski measured in Mondo sizing. SCARPA ski boots break on the half size, this means that a half size shares the same shell length as the whole size above it but the liners are lasted for each ½ size. For example, a 25.5 and 26.0 are the same shell size but the respective liners come pre-molded to the half size. Some skiers may want to downsize up to 1 full Mondo size, depending upon personal preference.

OPTIMIZED TOURING POINT

In order to maximize all efficiencies when moving uphill, some models with TLT fittings have moved the tech toe fittings further under the foot. This effectively makes for a more natural stride that offers significant energy savings, especially important on big days!

NOTE: binding mounting location is different than standard TLT mounting instructions.

MOUNTING INSTRUCTIONS:
boot center to ski center

  1. Mount the TLT heel piece in the standard mounting location.

  2. To mount the TLT toe piece: move the toe rearwards from ‘standard’ mounting location, towards the heel piece, by «X», the specified distance for each boot.

GAITER

ALIEN GAITER

Made with durable materials that combine protection and high lightness for improved insulation. The Velcro® closure helps the skier easily put on the boot and insert or remove the liner effortlessly.

MATERIAL

CARBON GRILAMID LFT®

A polyamide reinforced with long carbon fibers, which enhance the tensile strength and rigidity of Grilamid® without increasing its weight. This allows for thinner shell walls, resulting in a lightweight, compact, and highly performant product. Impact and stress resistance are also improved, helping to maintain consistent boot performance over time.

GRILAMID FG LFT®

Reinforced with long glass fibers, this material exhibits impact resistance and rigidity values 20–30% higher than those of short fiber, making it particularly suitable for lightweight applications.

SKI/WALK MECHANISM

SPEED LOCK SYSTEM LITE

Lacing system composed of the A-Light lever, lightweight and durable, a Dyneema® cord, two loops, and two metal hooks. With a single movement, the system allows locking or releasing the cuff from the shell, enabling the front opening or closing of the cuff. The lever’s attachment point on the shell is designed to prevent the accumulation of snow and ice.

CLOSURE SYSTEM

BOA® FIT SYSTEM

It ensures a precise and micro-adjustable fit, designed to deliver optimal performance even in the most extreme conditions. Once adjusted and secured, the BOA® Fit System maintains effective locking even after many hours of use.

INNER SHOE

TOUR LITE

Thermoformable Intuition liner, made with exclusive Intuition Foam. Classic tongue construction with elastic at the instep. Comfortable and easy to put on and remove after use. The double upper straps facilitate entry.

Materials
Icon

Grilamid FG LFT

This material is reinforced with long glass fibers, which provide higher strength and stiffness values than short fibers at equal percentages. The long-fiber structure allows an increase in stiffness of between 20 percent and 30 percent, making the material particularly suitable for lightweight applications that require high levels of strength. In addition, all long-fiber reinforced polyamides exhibit significantly higher values of impact resistance than conventional fiber reinforced materials.
Icon

Carbon Grilamid LFT®

This special high-performance polyamide is reinforced with long carbon fibers, which significantly improve the stiffness and resistance to extension of Grilamid®, while keeping the density unchanged compared to normal short fibers. This feature allows for reduced thicknesses in the shell and cuff areas, contributing to lightweight yet high-performance boots. In addition, the material offers greater resistance to impact and stress, maintaining optimal performance over time.
GAITER SHELL Construction

Gaiter Shell Construction

Gaiter construction is the ideal solution when the goal is to minimize weight without compromising performance. Designed specifically for lightweight touring boots and race models, this construction provides protection, precise fit, and a significant reduction in overall weight. The design allows high levels of comfort, downhill performance and water resistance to be maintained, even in the most demanding conditions.
