High performance and comfort come together in the Atomic Hawx Ultra 120 S BOA with a narrow 98mm last. With a stiff 120 flex, this narrow-fit ski boot is designed for all-mountain skiers who demand control without sacrificing ease of use. Prolite starts with a lightweight shell and cuff construction that wraps the foot, then reinforces key zones to deliver the strength and support needed for powerful energy transfer. Turn the BOA® Fit System dial in either direction for a responsive fit and all-day comfort. The firm and responsive Mimic Platinum Liner molds to the unique shape of your foot through the Mimic heat fitting process. A roomy 3D Stretch Toe Box in the liner allows for more length in the toes. Memory Fit provides advanced heat-fitting of shell and cuff in moments. Further customize the boot by adjusting forward lean through Power Shift or repositioning the Adaptive Fit System (AFS) Tongue.
