No subject to promotional offersThe Concept 11 GW Boa is an alpine ski boot for men from the brand Lange that will provide advanced skiers with effortless days on the slopes.
Designed with a Comfort Last, the Concept 11 GW Boa features a relaxed fit that adapts to all foot shapes. Furthermore, thanks to its Comfort Profile tongue, putting on and taking off the boot is effortless—you can even do it hands-free. The thermoformable Comfort Fit liner, 70% customisable, integrates a dual-density recycled polyurethane padding for precise and lasting support.
Moreover, the Suspension Blade technology ensures smooth shock absorption between the lower and upper cuff for increased control on every turn, while the adjustable flex allows you to tailor the boot’s stiffness to your style. The BOA® tightening system guarantees a precise fit, reducing pressure points and offering perfect edge-change control. Finally, the GripWalk® soles provide walking comfort and are compatible with alpine binding mechanisms.
The brand has combined comfort, performance, and environmental awareness to create the Concept 11 GW Boa, a boot that offers an intuitive and committed skiing experience.

| COMFORT FIT LINER | The thermoformable Comfort Fit liner is 70% customisable thanks to double-density recycled PU padding at the endpiece, ankle, and forefoot that adapts to the specific shape of your foot. Your ski boots thus become a natural extension of your body, providing relaxed comfort all day long. |
| DUAL CORE | Thanks to DUAL CORE, the boot compresses then actively expands by mobilising potential energy to deliver explosive power, rebound, and relaxation. World Cup-level precision, easy entry and exit, and an unprecedented level of performance, thanks to ski boots that are as reactive as they are dynamic. |
| GRIPWALK® | The GRIPWALK® soles feature a convex rubber band at the toes, providing more traction and a more natural walk. GRIPWALK® soles ensure better energy transmission and a complete alpine experience. |
| BOA® | The BOA® adjustment system equipped with the H+i1 mechanism is specially designed for alpine skiing demands, offering a precise, multidirectional micro-adjustable fit that evenly wraps the foot, reducing pressure points while providing effective heel hold and edge change control. |
