Scarpa Alien 4.0

Technologies and manufacturing processes

• ALIEN 4 GAITER

  The gaiter is made of nylon and spandex fibers woven together and provides greater elasticity for an easy fit. Also the rear part of the shell has a specially designed gaiter that prevents snow from penetrating downhill or when climbing.

• CARBON FIBER SHELL AND CUFF

  The reduced shell design guarantees maximum comfort when skiing, thanks to the closure system that does not cause pressure points. Ergonomic design adapts to the natural shape of the leg.

• SPEED LOCK SYSTEM LITE

  Lacing system consisting of the "A-Light" lever and a durable and lightweight Dyneema® cord, two tabs and two metal hooks. Thanks to the Speed Lock Lite system, the socket can be opened and closed with just one movement. The locking plate on the shell, which connects the lever to the shell, prevents the accumulation of snow and ice.

• Boa® Fit System

  "Ensures a precise fit designed for optimal performance in the most demanding conditions. Thanks to its micro-adjustable mechanism, it allows for quick and millimeter-precise adjustments, improving stability, comfort and control during technical performance."

• RACE 4.0 SL

  The thermoformable Intuition liner in the lightweight and comfortable lowcut version. Double Pull-Tab facilitates quick on and off.

• RESOLEABLE

  "This shoe can be repaired in one of the official SCARPA Resole stores. We recommend a repair before the wear becomes too severe to maintain performance and extend the life of your shoe or boot. View the full list of authorized centers on the store locator."

• Vibram

  "The leading brand in the development and production of rubber soles for sports, with a particular specialization in the outdoor sector. The research activities focus mainly on adhesion, performance and durability of the materials."

• INTUITION

  "Intuition liners represent the absolute Mau00dfstab in the world of thermoformable backcountry liners. Made from exclusive materials, they offer a durable, pressure point-free fit and high comfort at the same time. With excellent thermal insulation and exceptionally low weight, they ensure maximum efficiency and performance, even in the most demanding conditions."

• QUICKSTEP

  "Quick Step-In inserts enable easy and secure insertion and fixing of the ski boot in the binding. Specially developed lateral grooves facilitate insertion into the binding. The system is patented, extensively tested and guarantees reliability and high performance."

• Gaiter

  "The gaiter construction is the ideal solution when it comes to saving weight without compromising performance. Specially developed for lightweight ski touring boots and racing models, it offers protection, a precise fit and a significant weight reduction. The design ensures high comfort, good downhill performance and waterproofness even under the most demanding conditions."

• Carbon fiber

  "Thanks to its exceptional combination of lightness and strength, carbon fiber has established itself as the preferred material in the construction of racing ski touring boots. It is a composite material made of carbon fibers, which is usually embedded in a resin matrix that ensures shaping, maintains the structure and gives the finished product high stability. In addition to its low density and high strength, carbon fiber offers good thermal stability, acceptable fire resistance, resistance to chemical influences and temperature fluctuations as well as good insulating properties, making it ideal for use in extreme conditions."
