ALIEN

Regular price $749.00 USD

Whether you are an aspiring skimo racer or just looking for winter fitness at your local ski hill, the Alien represents an unbeatable blend of value and performance. The cuff and shell feature light but strong Grilamid® reinforced with glass and carbon fibers to deliver high function at a reasonable price. The Speed Lock Lite system connects the ski/walk lever with cuff operation via Dyneema® cord, providing simple, single-action transitions from up to down and back again. The Intuition liner offers legendary fit, comfort and warmth, while the floating BOA® closure system ensures quick, easy and durable fit tensioning. All of these features come together seamlessly in the Alien to support your winter fitness objectives.

  • Grilamid® FG LFT: Grilamid® with long glass fibers is a stiff and economical solution that provides lightweight power at a low weight
  • Carbon Grilamid® LFT: shell & cuff are made of CG-LFT, a carbon-reinforced polymer that is super-light but still stiff and strong
  • Speed Lock Lite: Simple and secure, with 2 forward lean positions, the Speed Lock Lite ski-walk mechanism is strong and reliable on the downhill and fast on the transitions due to a single action Dyneema® cord that closes the cuff
  • BOA® Fit System: Dial in the perfect fit with our exclusive floating BOA® Fit System closure, providing precise and secure adjustments with no pressure points
  • Vibram® UFO Sole: Made with TOP85 compound that offers great durability and grip in cold conditions

GRILAMID® FG LFT CUFF

BOA® FIT SYSTEM

The patented BOA® Fit System consists of three integral parts: a micro-adjustable dial, super-strong lightweight laces, and low friction lace guides. Each unique configuration is engineered for effortless precision delivering a connected, fast, customized, and durable fit, and is backed by The BOA® Guarantee. The Alien system is an exclusive floating system located under the waterproof fabric cover that contracts downwards on the instep of the liner as the dial is tightened, precisely controlling volume and fit.

GRILAMID® FG LFT CUFF

Stiffness and rigidity courtesy of a more economical solution versus full carbon fiber. The cuff features overlapping front panels, for good wrapping over the front of the shin and is closed by a single action Dyneema® cord interfacing with the ski/walk mechanism to speed transitions.

SCARPA Ski Sizing Chart




All SCARPA ski boots use 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 1/2 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.
