The Atomic Hawx Ultra XTD 105 BOA W is a versatile 98mm narrow-last, medium 105 flex freeride touring boot that delivers comfort and power, on-piste or out of bounds. This narrow ski boot is built with Prolite construction, giving you a lightweight shell that wraps the foot, with key structural reinforcements for powerful skiing. Micro-adjust the BOAA(R) Fit System in both directions to get a snug fit around your foot. A bootfitter can customize this boot for you using the heat-moldable Mimic Gold Liner, which shapes to your foot through the Mimic fitting process. Need more customization? Memory Fit provides advanced heat-fitting of shell and cuff in moments. This boot comes with Free/Lock 4.5, a robust ski/walk mechanism that securely locks the cuff to the shell. The cuff offers 54deg of epic natural movement and a more comfortable position when standing.
