How to Use This Calculator
- Enter Skier Weight (kg) — heavier skiers need stiffer flex to properly drive the boot.
- Select Skill Level (beginner, intermediate, advanced, expert) as the primary flex driver.
- Choose Skiing Style (all-mountain, carving, moguls, racing, touring) to refine the recommendation.
- Enter Height (cm) — taller skiers often benefit from slightly stiffer flex for biomechanical leverage.
- Review Recommended Flex and the Flex Range (Min-Max) — try on boots within this range at a specialty shop.
- Use Stiffness Category when comparing boots across brands, since flex ratings are not standardized industry-wide.
