Precise and lightweight all-mountain ski boots

The Atomic HAWX ULTRA 100 ski boots are positioned as all-mountain alpine ski boots with a flex rating of 100, designed for intermediate to advanced skiers who want to maintain responsiveness while retaining a certain degree of forgiveness. This intermediate flex promotes good feedback and controlled ski handling, which is useful for linking turns on various snow conditions. Their narrow 98 mm fit is designed for slender feet, providing a snug hold for precise feedback on edge grip and direction changes. Weighing approximately 1,750 g in size 26/26.5, the polyurethane shell and cuff contribute to a construction that strikes a good balance between lightness, durability, and stability.

Prolite and Energy Backbone Construction for Stability

Prolite technology is at the heart of the design of these Atomic ski boots, featuring a lightweight construction reinforced at strategic points in the shell. This approach reduces weight without compromising stiffness where the ski needs it most—particularly to ensure lateral support and stability during turns.The Energy Backbone, integrated into the shell, further enhances power transfer by concentrating stiffness in key areas, which helps deliver sharper edge engagement and better utilizes the 100 flex rating. This combination of technologies delivers a structured skiing experience, ideal for skiers who want to tackle technical terrain while enjoying a versatile all-mountain boot.

Memory Fit 3D Silver liner and 3M™ Thinsulate™ insulation

The Memory Fit 3D Silver liner is designed to adapt to the shape of the foot thanks to the Memory Fit system, which allows for simultaneous thermoforming of the liner, shell, and cuff. This custom thermoforming helps optimize support across the instep and heel while reducing pressure points—a feature that’s especially appreciated during extended outings. The integration of 3M™ Thinsulate™ technology provides targeted thermal insulation to retain heat inside the boot when temperatures are low. The combination of these features is designed to offer a fit that is both snug and comfortable, meeting the demands of regular winter use.

Customizable Fit and All-Mountain Use

The Memory Fit system on this model allows for comprehensive adjustment of the shell, cuff, and liner to better adapt the interior volume to the shape of the foot and lower leg. This customization is particularly beneficial for skiers seeking a narrow fit without sacrificing comfort. The all-mountain design of the Atomic HAWX ULTRA 100 ski boots reflects a commitment to balancing lightness, a precise fit, and adjustability, to accommodate a variety of uses on and off-piste throughout the WINTER 2027 season.

The unisex Atomic HAWX ULTRA 100 ski boots embody an all-mountain approach centered on a narrow 98 mm fit, a flex rating of 100, and a Prolite construction combined with the Energy Backbone—ideal for intermediate to advanced skiers seeking lightness, performance, and a customizable fit.
