The hard-flexing Atomic Hawx Ultra XTD 120 BOA is a versatile, low-volume freeride touring boot for those exploring the entire mountain. Uphill touring features and high-performance downhill capability come together in this 98mm-last narrow-fit ski boot. Prolite starts with a lightweight construction that wraps the foot, then reinforces key zones for the strength needed for powerful energy transfer. Turn the BOA® Fit System dial for a responsive fit and all-day comfort. The firm Mimic Platinum Liner molds to your foot through the Mimic heat fitting process. Both shell and cuff can be heat-molded through in-store Memory Fit. Adaptive Fit System (AFS) Tongue can be repositioned for a perfect fit over your foot and shin. The cuff offers 54º of natural movement for a relaxed stride and comfort when standing. This touring boot comes with Free/Lock 4.5, a robust ski/walk mechanism that securely locks the cuff to the shell and has adjustable forward lean.
