The stiffest model in the womens Hawx Ultra W range, the Atomic Hawx Ultra 115 S BOA W offers a low-volume fit with a 98mm last, delivering uncompromised performance for women skiers. By using an ultra-slim profile, then reinforcing critical zones, Prolite construction creates a lightweight boot that optimizes power transfer. BOA Fit System uniformly wraps the foot for a more secure feel and micro-adjustability. For a customized fit, the Mimic Platinum liner can be heat-molded to match the precise shape of your foot, while Power Ankle Lock, a dense, asymmetrical liner technology, ensures a secure and long-lasting heel hold. Memory Fit provides advanced heat-fitting technology for a customized shell and cuff. Power Shift lets you adjust forward lean to change your stance angle or alter the flex of the boot. A removable Adaptive Fit System (AFS) Cuff makes more space in the calf, while the 3D Stretch Toe Box adds a little extra length in the big toe.
