All-mountain skiers seeking a more forgiving boot in a narrow 98mm last will appreciate the fit and performance of the Atomic Hawx Ultra 100 BOA. The BOA® Fit System encloses the foot and reduces downward pressure for a comfortable design you can wear all day. Featuring Prolite technology, this revolutionary design uses a lightweight shell with reinforcements only where needed, optimizing power transfer. The soft Mimic Silver liner with Ankle Lock for enhanced heel hold feels good out of the box and can be customized using Mimic technology to help shape the liner around your exact bone structure. The asymmetrically shaped 3D Stretch Toe Box in the liner is ‘Big Toe Friendly’, adding a bit of extra length and comfort in the toe area. For even further customization, Memory Fit reshapes the cuff and shell to your leg and foot. This is an uncompromising boot you can trust on all terrain.
