| COMFORT FIT LINER | The thermoformable Comfort Fit liner is 70% customisable thanks to a dual-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 all-day relaxed comfort. |
| DUAL CORE | Thanks to DUAL CORE, the boot compresses then actively expands by harnessing 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® | GRIPWALK® soles feature a convex rubber band at the toe area, providing more traction and a more natural walk. GRIPWALK® soles ensure better energy transfer and a complete alpine experience. |
| BOA® | The BOA® adjustment system, equipped with a H+i1 mechanism, is specially designed for alpine skiing demands, offering a precise, multidirectional, micro-adjustable fit that uniformly wraps the foot, reducing pressure points while providing strong heel hold and edge control. |
