Atomic HAWX PRIME R85 Ski Boots

The Atomic HAWX PRIME R85 women’s ski boots are designed for skiers looking for a comfortable fit for alpine skiing, with all-mountain versatility covering a variety of slopes and terrain. Their 85 flex provides flexible support that remains physically accessible, while the 100 mm Medium Fit width is designed for feet of average width. The polyurethane shell and Prolite construction with targeted reinforcements are designed to balance foot support with efficient power transfer. Finally, the combination of the Mimic Bronze liner with Memory Fit and GripWalk technologies is designed to provide personalized comfort and improved ease of walking.

A Medium Fit for the comfort of all-mountain skiers

The Atomic HAWX PRIME R85 women’s ski boots are positioned as an all-mountain model, designed to handle all types of terrain in alpine skiing. With a width of 100 mm —known as Medium Fit—they are suited for feet of average width, striking a balance between comfort and precision in support. The 85 flex is described as flexible, allowing skiers to benefit from responsive support without being excessive, for more confident control during push-offs and changes in pace. The stated weight of 1,774 g per boot in size 24–24.5 reflects a design engineered to avoid unnecessarily weighing down movements, which helps reduce fatigue throughout the day. A women’s-specific cuff and an Adaptive Fit System Cuff with a removable spoiler allow for adjustment of the upper volume, improving comfort around the calf and overall fit.

A Prolite polyurethane shell for power transfer

The structure of the Atomic HAWX PRIME R85 ski boots is based on a polyurethane (PU) shell and collar—a material prized for its flex characteristics and its ability to provide progressive support. The Prolite construction combines a relatively slim shell profile with targeted reinforcements in key areas, designed to maintain a good level of stiffness where power needs to be transferred to the skis.The Energy Backbone—the boot’s reinforced “back”—optimizes this power transfer and torsional stability, resulting in sharper edge engagement. The 15° forward lean and 3° lateral canting help position the skier in a stance suited for alpine skiing, promoting effective pressure on the tongues and improved lateral stability.

Mimic Bronze and Memory Fit liner for a personalized fit

Inside, the Atomic HAWX PRIME R85 ski boots feature a thermoformable Mimic Bronze liner, designed to conform precisely to the shape of the foot after a visit to the service center. This liner provides anatomical support for the heel and ankle to limit unwanted movement within the boot and improve overall feel. Memory Fit technology allows you to thermoform not only the liner but also the shell and cuff in just a few minutes, creating a personalized fit across the entire foot and leg. The 35-mm Velcro strap helps secure the top of the cuff and distribute tension more evenly, while the tool-free, adjustable 6000-series aluminum buckles provide precise adjustment of the fit around the foot and instep. The overall design aims to combine lasting comfort, reliable support, and a consistent feel for all-mountain skiing.

GripWalk ISO 23223 standard for easier walking

The Atomic HAWX PRIME R85 ski boots feature ISO 23223 GripWalk soles with a flex zone, which improve traction when walking on packed snow or hard surfaces. This type of sole is designed to maintain power transfer compatible with GripWalk bindings while offering better walking ergonomics than traditional alpine soles. The adjustable canting feature also allows for the use of compatible canting shims to fine-tune lateral alignment if necessary. The advertised medium volume and all-mountain-focused design make this a solid choice for female skiers seeking a balance between everyday comfort, control on the slopes, and practicality when moving around the resort.

The Atomic HAWX PRIME R85 women’s ski boots are thus designed as all-mountain alpine ski boots with a Medium Fit, combining a flex rating of 85, a Prolite polyurethane shell, a thermoformable Mimic Bronze liner, and GripWalk ISO 23223 soles for a personalized fit and precise control on all terrains.
