| Bottom Line | A lightweight, comfortable, powerful freeride boot for skiers in need of a tapered last and narrow fit | The Promachine boasts a friendly fit with a race-inspired construction that excels in all types of terrain and conditions | A surprisingly comfortable and versatile boot that held its own on groomers but may be too soft for more advanced, off-piste shredders | An approachable race-inspired boot with a softer flex and a comfortable liner, that is responsive across a variety of terrain and conditions | A highly rigid boot that loves high speeds and long GS turns but is less forgiving in choppy conditions |

The minimalist Mimic liner in the Atomic Hawx Ultra provided an acceptable amount of comfort and warmth throughout the testing process but did not boast the best out-of-the-box fit. While it was perfectly snug around the foot profile, the narrow shaft created discomfort in the calf and shin. Some extra space under the arch and in the heel pocket began to create a roomy feeling by the end of the testing period. This led to over buckling to compensate for the fit issues, which limited our ability to flex our shin and knee over the high cuff. While the fit wasn't perfect, the boot felt strong and stiff amongst varying conditions on the mountain.
The transfer of power and responsiveness of the Atomic Hawx Ultra felt consistent across various terrain and conditions. The boot moves with you and sends feedback. The Energy Backbone reinforcement provides extra strength in the spine and is aimed at improving lateral energy transmission. In practice, this means more stable and powerful edge-to-edge transfer. The prepositioned 15-degree forward lean and 4-degree ramp angle sets the skier up in a neutral athletic stance. The Atomic Hawx Ultra offered a lively and energetic feel, though there were discrepancies between the performance and the fit.
The fit issues became apparent in steeper terrain, choppy crud, and bumps, where an inability to maintain a bend over the high cuff forced us into the backseat. Dead space within the heel and ankle region (to be discussed in the Fit section below) caused unwelcomed movement within the boot, further hindering performance in mixed terrain that required a greater variation in movement. This may not be a problem for those with wider heels but was a problem for our testers.
The Atomic Hawx Ultra provided more torsional movement than the stiffer Salomon S/Max, to what felt like a more progressive flex pattern. For those looking for more, the Power Shift feature in the Hawx Ultra S line allows the forward lean to be adjusted to a more or less aggressive stance (13, 15, or 17 degrees).
Regarding the flex rating, the boot felt stiff, but if we did a blind flex test after a day of skiing, we would have guessed the flex was closer to 110. While the flex rating isn't exactly universal across the industry, other boots in the lineup with the same flex proved to be noticeably stiffer. The Energy Backbone, along with the reinforced PU support in key zones, does, however, keep this boot sturdy and rigid when it needs to be.
We struggled with comfort thanks to pinch points from a tight, narrow liner and shell construction, though this faded the more days we skied in the boot. The Mimic platinum liner feels thick and protective despite its very minimal design. Lined with a layer of 3M Thinsulate, the boot scored reasonably well in the warmth department. The shell is made of thinner layers of polyamide and polyurethane to keep the product's weight down. While this boot was warm in California weather, the thin construction may limit the boot's ability to retain warmth in colder mountain temps. We loved the lightweight nature of this boot. It was one of the least bulky or obtrusive options in the lineup.
Despite the underwhelming fit, the Atomic Hawx Ultra provided good comfort both on and off-piste. While there was initial numbness and pressure before molding, there were little pain or pressure issues during the testing period. The stock alpine soles limit the walkability of the boot, but it didn't stand out as uncomfortable or difficult. The latest version comes equipped with Gripwalk soles, both of which are replaceable to accommodate a variety of binding norms. Bottom line, this provides an adequate amount of comfort for such a tapered, narrow shell and liner combination. Race-style boots of this caliber are often not as snug or cozy as the Atomic Hawx Ultra.
One of Atomic's main goals in liner development is to create the best out-of-the-box fit possible for the consumer. You will notice Atomic liners are slightly more tapered than Salomon liners, which explains why our first impression was that this boot felt like a slipper. We wanted to like this boot out in the field, but the fit hindered us from accessing the level of downhill performance we were looking for. But keep in mind - no foot is created equal, so visit your local boot fitter to cross-reference our comments based on your personal foot profile and its compatibility to a boot.
The toebox was appropriately shaped for a 97-millimeter last, giving us the perfect amount of support around the metatarsals. The V3 Tongue System and Adaptive Fit Cuff perfectly shape to the contours of the instep and ankle. The cuff, however, airs on the taller side, sitting high on the shin. It also is made for a thinner calf and shin profile. Those of us with larger calves felt pinching and loss of feeling in the shin throughout the day. While the fit was comfortable in some aspects, the cuff height was ultimately difficult to overcome.
The heel pocket appeared to be snug and pre-shaped to accommodate a narrow heel, but even after molding, we still experienced heel lift on our test days. The high cuff height exacerbated the heel lift issue by initiating the need to reach up and out over the cuff with the shin. Luckily, heel wedges exist that can set your shin higher above the cuff, though it will slightly increase the sole's ramp angle.
Most Atomic liners feature an asymmetric construction that is considered a more anatomic design than more linear, symmetrical boots. This means an asymmetric tongue, toe box, and collar shape that bends around the foot and lower leg's contours. This added points to the fit score for the Atomic Hawx Ultra.
The construction of the Atomic Hawx Ultra was built to last, meaning more days in the boot before the pack-out phase begins. Atomic helped increase longevity by using a Dynashape foam in the liner and pre-shaping the heel and ankle zones to maintain a longer-lasting fit. The Atomic Hawx Ultra comes equipped with a fully customizable Prolite shell and Mimic platinum liner. This means the construction should be able to be altered through some variation of molding, punching, grinding, or canting.
We really liked the Adaptive Cuff System feature. The cuff is made with a removable spoiler in the upper spine to free up space for those with bulkier shins and calves. This is a constant issue for one of our testers, so she welcomed the Adaptive Cuff with open arms. For those with the “narrow feet, large calves” issue — keep your eye out for boots with a “tulip-shaped” cuff.
Like most boots these days, the forward lean can be adjusted to 13, 15, or 17 degrees depending on how aggressive a skier you are. The 13-degree angle is more relaxed, while the 17-degree angle is closer to a racer positioning. The Power Shift feature is NOT included in the entire Hawx line this year, so if you want this feature, find a boot that includes an “S” in the product line. For example, “Atomic Hawx Ultra 115 SW.” The S stands for Power Shift, and the W stands for Women.
This is one of the most lightweight women's alpine boots on the market. Atomic has gone through an incredibly thoughtful development process to blend the best elements of their alpine and touring boots. For this reason, the price point sits in the middle to high range of our lineup. Despite our fit issues, it is a high-performing boot suited for any female who loves to shred. And if you love to shred, you're probably willing to dish out the extra few bucks for an excellent boot.
