2026 Atomic Hawx Ultra S 120 BOA Ski Boots – Precision Fit with Stiff All-Mountain Performance
Confidence, control, and comfort in a lightweight design.
The Atomic Hawx Ultra S 120 BOA is built for advanced all-mountain skiers who want the perfect balance of high-performance power transfer and all-day comfort. With a stiff 120 flex and narrow 98mm last, this boot delivers precise control in demanding terrain while remaining easy to get in and out of.
Prolite construction keeps the shell lightweight yet strong, reinforcing key zones for maximum stability. The BOA® Fit System replaces traditional buckles across the lower foot, providing uniform wrapping, fine-tuned adjustability, and superior hold without pressure points. Inside, the Mimic Platinum liner heat-molds to your exact foot shape, while the 3D Stretch Toe Box gives extra length where you need it most.
For even more customization, Memory Fit heat-molds the shell and cuff in minutes, the Adaptive Fit System (AFS) Tongue adjusts fit over the shin and instep, and Power Shift lets you dial in your forward lean. Equipped with GripWalk soles for confident walking traction, the Hawx Ultra S 120 BOA is made for skiers who demand both precision and comfort.

FIT |
Last: 98 mm - A narrow performance last ideal for skiers with slim feet, but fully heat-customizable to accommodate many average-width foot shapes. Memory Fit - Atomic’s advanced heat-fitting technology that customizes the shell, cuff, and liner in minutes. Using Memolink, a special additive that increases the stretch and moldability of Atomic’s plastics, the boot can expand up to 6mm in the forefoot and up to 10mm at the ankle. The result is a permanent, anatomical fit tailored precisely to your foot. For best results, visit a professional bootfitter. |

LINER |
Mimic Platinum Liner - Designed to feel right from the very first step, this liner uses supportive, heat-moldable material in the heel, ankle, and tongue. Once softened in the oven, it molds precisely to the shape of your foot and hardens for a fully customized, secure fit. 3D Stretch Toe Box - Asymmetrically shaped for left and right feet, the 3D Stretch Toe Box enhances both first fit and customization potential. Its “Big Toe Friendly” design provides extra length where you need it most, allowing a subtle stretch to fine-tune comfort and performance. 3M™ Thinsulate™ Insulation - Engineered to keep feet warm, light, and responsive—even in the coldest and dampest alpine conditions. Adaptive Fit System (AFS) Tongue - Swap tongues to dial in volume and fit over the shin and instep. Extra low- and high-volume tongues are available separately for further customization. |

Energy Backbone - Reinforcement in key zones giving extra strength and edge grip for powerful skiing. |

STANCE |
Forward Lean – 15° (Default) - Designed for balanced all-mountain performance and power transfer. 3° Shell Rotation - Slight inward shell rotation aligns the boot naturally with your stance for improved edge engagement and comfort. Power Shift - Allows quick adjustment of forward lean between 13°, 15° (default), or 17° for a personalized stance. On 110 / 120 models, adding a bolt increases flex stiffness, while on 130 models, removing a bolt softens the flex for fine-tuned performance. |
