DUAL CORE [LANGE]

Lange's "power injection" method allows the simultaneous injection of two different durometers of plastic at the exact same time. This unique mono-injection process allows targeted power transmission and shell wrapping; and creates a DUAL CORE sandwich construction throughout the shell, resulting in livelier rebound, response, and total control through the turn.

ANATOMIC JUNIOR FIT

Lange's JUNIOR FIT is designed for smaller calves and foot chapes to deliver enhanced, junior-specific comfort, fit and performance.
Fit & Sizing

Alpine Ski Boots Sizing Guide

Finding the right size ski boot comes down to Mondopoint sizing, a scale based on the length of your foot in centimeters from heel to the tip of your big toe. Try tracing your foot on a piece of paper for the most accurate measurement. Use this measurement along with the following chart to help choose your ski boot size.
