The Hagan Boost 105 exists for skiers who look at big lines and think why not. As the widest ski Hagan has ever built, this freeride touring machine redefines what’s possible when uphill efficiency meets downhill ambition. Designed to climb without complaint and descend without restraint, the Boost 105 thrives where speed, steepness, and commitment converge.
At 105 mm underfoot, the Boost 105 delivers effortless float in deep snow while maintaining composure when conditions turn less than perfect. Its carefully balanced shape and rocker profile allow it to pivot quickly in tight terrain, yet stay planted when you open it up. Whether you’re charging wide alpine faces or navigating complex backcountry features, this ski encourages you to ski faster, harder, and with more confidence.
What truly sets the Boost 105 apart is its innovative construction. By pairing a Kevlar-reinforced layup with a poplar/karuba core, Hagan created a ski that’s powerful, damp, and surprisingly light. The result shocked even Hagan’s own testers: a freeride touring ski that feels playful and maneuverable, yet stable enough for high-speed descents. Built on over 100 years of touring ski expertise, the Boost 105 pushes the boundaries of modern ski touring performance.

This guide is for alpine (downhill) skis. Ski length depends on your height, your ability, and how you like to ski. Use this chart as a starting point, then talk to us about the ski itself: rocker, width, and turn shape all change how long a ski feels.

Quick Rule
- Beginner: ski tip around your chin. Shorter skis turn easily.
- Intermediate: tip between your nose and forehead.
- Advanced: tip around the top of your head, for stability at speed.
- Expert: about 5cm longer than advanced, for hard charging and big-mountain terrain.
Adjust For
- Go longer: heavier build, fast skiing, deep snow, lots of tip rocker.
- Go shorter: lighter build, tight trees and moguls, uphill touring.
- Telemark: if you want a ski for tele, we recommend going down about 10cm from the length you normally like.
