- Setting 100
The fit of the boot (or last) is the width of the foot measured at the fifth metatarsal (widest part of the forefoot). Determines the skier's level of control and precision. For a good balance between comfort and control, choose a boot that matches the overall volume and length of your foot. Adjustment between 92-95 mm: Narrow, Fit between 97-99 mm: Medium, Adjustment between 100-102 mm: Comfort

- Flex 100
The 'flex' of a boot indicates the level of support the boot will provide. The higher (stiffer) the bending rate, the stiffer and more reactive the boot. The lower (softer) the bending rate, the more tolerant and comfortable it is.

- Level 100
Choose the boots that offer the best comfort/performance ratio. For a beginner skier, a flex (<80) is recommended and for an expert skier a higher flex (>90) is recommended.

Technology:
- Dual Core
As you ride and put on your boots, DUAL CORE actively compresses and expands, harnessing potential energy to deliver explosive power, snap and bounce.

- Dual 3D Liner Sport
Dual 3D liners are pre-shaped to match the inner shell for the most precise and accurate power transmission, and around the foot for the most comfortable anatomical fit. The Dual 3D Sport version is 60% customizable (shin, ankle, instep, forefoot) with integrated low-density foam in key fit zones for comfort and support.

- 100 mm Performance Fit
The Lange performance fit provides a precise yet comfortable 100mm last designed for skiers with medium volume feet or skiers looking for slightly less foot compression for all day comfort.

- Natural Stance
Lange's unique natural stance complements modern ski designs, offering a lower ramp angle (4º) and a more neutral, upright stance to increase balance and control for more efficient power transfer and less quad fatigue. 

- Gripwalk Mounted Soles
Gripwalk outsoles have a thick rubber tread and a convex toe profile, offering increased traction and a more natural foot motion for improved walking and hiking comfort. Alpine DIN soles also available, sold separately.
