Product Info
The Atomic Hawx Ultra 120 S BOA Ski Boots, arguably the best fit in the industry for narrow feet and ankles, get BOA® and never looked or felt so good. Year after year, the Ultra 120 knocks it out of the park in sales for evo, and this version is the finest yet. Built with Atomic's famed True Flex Polyurethane for consistent flex no matter the temperature and with Memory Fit heat molding that truly customizes the fit, this boot is a winner from start to finish.
Product Details
Fit
Last: 98 mm – A narrow last suitable for those with narrower than average feet (heat customizable to fit many average width feet).
Memory Fit – Advanced heat-fitting technology creates a fully personalized shell, cuff and liner in minutes. The key is Memolink, Atomic's special additive that improves the moldability and stretch of their plastics. Expansion can be up to 6mm forefoot width and up to 10mm ankle width, resulting in a permanent and complete anatomical fit in minutes. See your bootfitter for details.
Flex
Flex: 120 – A stiff flex for advanced and larger individuals
Liner
Mimic Platinum Liner – This is a boot that feels right from the very start. The heel, ankle, and tongue feature a layer of supportive, heat-moldable material. After being softened in the oven, this material mimics the precise shape of your foot and hardens for a perfect custom fit.
3D Stretch Toe Box – Asymmetrically shaped for left and right, the new 3D Stretch Toe Box takes first fit and customization potential to the next level. Its ‘Big Toe Friendly’ construction maximizes the liner’s available length allowing for a little extra stretch when important millimeters are required to achieve the perfect fit.
3M™ Thinsulate™ Insulation – Keeps feet warm and responsive even in extremely cold and damp conditions.
Adaptive Fit System (AFS) Tongue – Tongues can be swapped for lower or higher volume versions (extra tongues available separately).
Shell Materials & Design
Shell – True Flex Polyurethane
Cuff – Polyurethane
Prolite – Instead of starting with a standard construction and cutting material away to save weight, Prolite does the opposite. It starts with the slimmest possible profile and then builds up reinforcements in key areas where strength is needed - like the Energy Backbone down each boot spine.
Energy Backbone – A reinforced, asymmetric backbone providing extra strength for powerful skiing plus enhanced lateral energy transmission for better edge grip.
Dual Sided Cuff Alignment
Stance
Forward Lean – 15˚
3˚ Shell Rotation
Power Shift – Forward lean can be quickly adjusted to 13°, 15° (default) or 17°. Add a bolt on 110 / 120 models to stiffen flex. Remove a bolt on 130 model to soften flex.
Dual Sided Cuff Alignment
Buckles
2 6000 Series Aluminum Cuff Buckles
BOA® Fit System Lower Closure – Allows more even distribution of pressure over the forefoot and instep and infinite precise adjustment.

Sole
Cantable GripWalk ISO 23223 Grip Pads

Ability Level
Advanced-Expert Whether you charge the steepest lines, hit the biggest jumps in the park or carve with race-like precision, advanced to expert level skis, snowboards, boots and bindings are for the more aggressive rider. In skis and snowboards, you'll often find layers of metal, carbon or other stringers for rigidity and power, while advanced to expert level boots and bindings are usually on the stiffer side of the spectrum for rebound and precision steering.
