Concept 12 GW BOA®

The fusion of performance and comfort for passionate skiers. The Lange Concept 12 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 Easy Entry and Exit design with the Comfort Profile tongue to create a perfect-fitting boot that's easy to step into and performs well. Our Suspension Blade technology connects the upper and lower cuffs for smooth power transfer and absolute confidence in every turn. Designed with the micro-adjustable BOA® Fit System and a customizable liner, the Concept 12 boots strike a good balance between fit and performance so you can focus on having fun. Their 120 flex is designed for advanced skiers looking for performance and precision without compromising fit and comfort. A simple adjustable insert on the cuff softens the flex by 8%.

Maximum comfort, all-day support

Our 103mm Comfort Last is designed for a relaxed fit with plenty of room for different foot shapes, providing excellent support and maximum comfort all day long.

Flex performance

A stiff flex of 120 is designed for advanced skiers looking for performance and precision.

Increased skiability, improved fit

Dual Core technology combines rigid and flexible plastics that ensure targeted power transmission and optimal flex, for an increased level of responsiveness, control and fit.

Easy to put on and take off

Passive lower shell articulations combined with our Comfort Profile tongue allow for easy, hands-free entry and exit.

Customizable comfortable fit

The thermoformable Comfort Fit liner is 80% customizable thanks to dual-density recycled PU padding in the heel, ankle, and forefoot that adapts to the specific shape of your foot. Your ski boots become a natural extension of your body, for relaxed comfort all day long.

Increased confidence, increased control

Our Suspension Blade technology connects the upper and lower cuffs for smooth shock absorption and increased control, so you can ski with more confidence.

Adjustable flex

Our Flex Adjust system features a simple adjustable insert on the cuff that allows you to adjust the flex to suit your skiing style by changing the elastomer.

Micro-adjustable precise fit

The BOA® Fit System with H+i1 mechanism is specifically designed for the demands of alpine skiing, providing a precise, multi-directional, micro-adjustable fit that evenly wraps the foot, reducing pressure points while providing effective heel support and edge change control.

All-terrain grip and alpine compatibility

Pre-mounted GripWalk® soles feature a rubber surface and a raised toe cap for a more natural walking motion and increased grip. They are also fully compatible with alpine binding mechanisms.

Reduced carbon footprint

Lange seeks to reduce the overall carbon footprint through the use of recycled materials, including a shell containing at least 30% recycled PU, a 100% recycled Velcro strap, and a 50% recycled PP insole.
