The Fit of the boot (or last) is the width of the foot measured at the 5th metatarsal (widest part of the forefoot). It determines the level of control and precision of the skier. For a good ratio between comfort and control, choose a boot that matches the overall volume and length of your foot. Fit between 92-95 mm: Narrow, Fit between 97-99 mm: Medium, Fit between 100-102 mm: Comfort

The “flex” of a boot indicates the level of support that boot will deliver. The greater (stiffer) the flex index, the more rigid and reactive the boot will be. The lesser (softer) the flex index, the more tolerant and comfortable.

Associated technologies

Shell
DUAL CORE
As you drive and flex into your boots, DUAL CORE actively compresses and expands – harnessing potential energy to deliver explosive power, snap, and rebound. Imagine World Cup precision and response, easy entry-and-exit, and a new level of ski boot performance as reactive and dynamic as your own body.

Liner
DUAL 3D LINER WC
DUAL 3D WORLD CUP LINERS are pre-shaped to match the inner shell for the most precise and accurate power transmission.

Fit
97mm PRECISION FIT
Lange's PRECISION FIT provides an exact, race-inspired 97mm last designed for skiers with low volume feet or skiers seeking more foot compression and control without sacrificing comfort.

Shell
NATURAL STANCE
Lange's unique NATURAL STANCE compliments modern ski designs, offering a lower ramp angle (4⁰) and more neutral, upright stance to increase balance and control for more efficient power transfer and less quad fatigue.
