Designed for male skiers looking to improve their skills on all types of terrain without sacrificing everyday comfort, the Lange CONCEPT 11 GW_BOA is aimed at intermediate to advanced skiers seeking versatile all-mountain gear. With an adjustable flex rating of 110, they offer a dynamic response suited to experienced skiers who tackle both groomed runs and varied terrain. The integrated BOA® Fit System redefines the convenience of lacing, while the Overlap construction ensures precise power transfer. The result: a technical boot that doesn’t compromise on comfort during a full day of skiing.

Flex and fit: a profile designed for advanced skiers

The 110 flex places the Lange CONCEPT 11 GW_BOA in the medium-to-high stiffness category, suitable for skiers who want genuine feedback from the snow without the harshness of an expert flex. This flex is also adjustable and can be softened by 8%, allowing you to tailor the boot’s response to conditions or personal preferences. The 103 mm last, which corresponds to a high volume, ensures a generous fit in the metatarsal area, ideal for wide feet or skiers sensitive to lateral compression. The integrated Comfort Last technology directly contributes to this controlled width, maintaining comfort during long sessions without compromising precision on the slopes.

Comfort and Customization: A Liner That Adapts to Your Foot

The Core Custom2 inner boot is 70–80% thermoformable, meaning it can be molded to the precise shape of your foot during a boot-fitting session. This customization improves both support and thermal comfort by eliminating recurring pressure points. The dual-density recycled polyurethane padding provides cushioning tailored to the repeated impacts of alpine skiing, while the Sport Footbed absorbs vibrations and impacts from the soil. The Comfort Profile Tongue reduces shin impact and makes it easier to get in and out of the boot—a detail you’ll appreciate at the end of the day. For skiers looking to take customization a step further, this construction is fully compatible with adjustments by a professional bootfitter.

Lacing and Convenience: The BOA® System for Precision

The closure system combines two complementary approaches. The lower part of the boot is equipped with the BOA® Fit System H+i1, specifically designed for the demands of alpine skiing: it delivers a precise, multidirectional fit with a single motion, even while wearing gloves. The upper section retains traditional buckles, allowing for segmented adjustment of the collar’s support. This combination of systems offers great flexibility, whether you’re preparing your gear before hitting the slopes or adjusting your fit throughout the day. The Easy Entry & Exit System also makes it easier to put on and take off your boots, reducing the strain associated with the rigidity of the polyurethane shell.

Power Transfer and GripWalk Compatibility

The polyurethane shell’s Overlap construction ensures a continuous wrap around the foot, promoting direct transmission of the skier’s intentions to the ski. Suspension Blade technology connects the Lyfran cuff to the shell, absorbing vibrations while maintaining smooth power transfer during each step. GripWalk®-compatiblesoles make walking on hard soil easier and offer compatibility with modern alpine bindings equipped with the GripWalk standard, without compromising the safety of the ski-boot interface.

With its adjustable 110 flex, generous 103 mm last, and thermoformable liner, the Lange CONCEPT 11 GW_BOA is a solid choice for intermediate to advanced skiers who regularly ski on varied terrain and seek a balance between technical performance and lasting comfort. The combination of the BOA® Fit System and traditional buckles offers a level of adjustment versatility rarely found in this category of alpine ski boots.
