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.
