Comfort meets performance for dedicated skiers. The women's Lange Concept 10.5 BOA® ski boots set a new standard for comfort and ease of use in an all-mountain ski boot. They combine our roomy Comfort Last 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. With a women's-specific cuff and customizable liner plus the micro-adjustable fit of the BOA® Fit System, the Concept 10.5 boots balance fit and performance to keep you focused on the fun. Their strong 105-rated flex is designed for advanced skiers looking for performance and precision. A simple adjustable insert on the cuff lets you soften the flex by 8%.
