The Head Formula 110 Ski Boots are a great example of race-ready tech finding its way into all-mountain gear. It's built around a Liquid Fit Liner, which is designed to let a bootfitter actually inject material into the liner, allowing it to be custom-shaped to your foot in a way that used to only be available to the most elite ski racers. Paired with the full suite of bootfitting technologies, like Flex Tuning, Rear Support Tuning, and adjustable Cuff Alignment, it allows you and your bootfitter to work together to get a level of support, comfort, and fit that no other boot can match.
- Formula Liquid Fit Liner allows a bootfitter to inject material into the liner to give you a truly custom fit with unmatched hold, support, and flexibility
- Flex Tuning, Rear Support Tuning, and adjustable Cuff Alignment all work together to allow a bootfitter free reign to customize the boot to your foot
