Put comfort first with boots that fit and feel as great as they ski. The Lange Concept 10 ski boots set a new standard for comfort and ease of use in an all-mountain ski boot. They combine our all-new Easy Closure System and our Easy Entry and Exit design with Comfort Profile Tongue to make a boot that's easy to get into, fits great and performs great. Our Suspension Blade technology connects the upper and lower cuffs for smooth power transfer and confidence through every turn. Designed with our roomy Comfort Last and a customizable liner, the Concept 10 boots balance fit and performance to keep you focused on the fun. Their 100-rated flex is designed for intermediate skiers who prioritize all-day comfort. A simple adjustable insert on the cuff lets you soften the flex by 8%.
