    Features

    • 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 4.0 system is mounted to a protective Pebax tongue panel and compresses down on the instep as it’s tightened.

      SPEED LOCK LITE SYSTEM

      The Speed Lock Lite System is a simple and effective system that uses a Dyneema® cord integrating the ski/walk mechanism with the cuff, allowing for quick and efficient single-action transitions. Flipping the lever up both opens the cuff and engages walk mode, while locking it down closes the cuff and sets the ski mode. Set it and forget it - once the cord is adjusted to the proper length you simply switch back and forth between ski and walk modes with one easy motion.
