Description
Atomic's Hawx Ultra 130 S Dual BOA is a narrow-fit alpine ski boot that closes with two BOA dials, a lower-shell dial and a cuff dial. The last is 98mm Narrow Width / LV and the flex is 130; one boot in size 26/26.5 weighs 1,896 g, and sizes run from 25/25.5 to 30/30.5 Mondopoint.
Atomic's catalog names the hardware: BOA H+i1 Dual Pull and BOA H+i1 Single Pull dials, the Dual BOA Fit System Alpine, plus a 40/45mm Cam Strap. No buckles appear on that list. The feature explanations here come from the product copy Atomic ran for this boot between October 2025 and April 2026. That copy says the system wraps the leg and foot from cuff to shell, calls the dials micro-adjustable and credits the non-elastic strap with direct energy transfer and a responsive feel.
The shell is PU, and so is the cuff. Atomic's Prolite construction keeps them light and reinforces key zones, and the catalog adds Energy Backbone, reinforcement Atomic says brings strength and edge grip. Memory Fit is Atomic's heat-fitting process for reshaping the plastic shell and cuff to your leg and foot. The liner is Mimic Platinum: heat-moldable Mimic material lines its heel, ankle and tongue, softening in the oven and setting to your shape. Power Ankle Lock, a liner layer Atomic calls dense and asymmetrical, is aimed at heel hold; at the big toe, Atomic's 3D Stretch Toe Box allows extra length.
Power Shift offers 13°, 15° (default) and 17° of forward lean, and the ramp angle is 4°.
Atomic lists it for experts only. Medium or wide feet usually start out tight in this last, and intermediates, or advanced skiers not yet driving a 130, will find it a lot of boot. Atomic's specs include no walk mode.
Its sole follows the GripWalk ISO 23223 norm, with Cantable GripWalk Grip Pads; before you ski it, have a technician confirm that your binding works with that sole.
In the shop, PTO does the shell check, heat-molds shell and liner, and checks your bindings against the boots.

Atomic Hawx Ultra 130 S Dual BOA
Hawx Ultra family · 26/27BOA
Flex 130
Very StiffLast Width
98mm— Narrow (96–99mm)
This boot's case rests on its cuff. Atomic's 26/27 datasheets give it the same narrow, low-volume 98mm last, 130 flex, Prolite PU shell and cuff, lean settings and 4° ramp as the four-buckle Ultra 130 S and the single-dial Ultra 130 S BOA. As archived in October 2025, January 2026 and April 2026, Atomic's US page for that boot said its one dial replaces two buckles on the shell. This one adds a second dial at the cuff, and that changes how the boot flexes as well as how it closes.
Think of the cuff dial as evening out the flex rather than stiffening it. A retailer's bootfitter who tested the 25/26 boot felt the cuff dial made the whole upper boot work essentially as one unit, so the flex built more linearly than on a buckle cuff left a little loose for extra ramp-up. Another 25/26 review credits the cuff cables with smoothing out the flex. If you like a loose top buckle for a more progressive ramp-up, the four-buckle version keeps that option.
None of this matters until the shell fits, and on this last a tall instep is the first thing to check. The same bootfitter found the narrow Ultra cuff made the 25/26 boot hard to get in and out of for some people, tall insteps in particular, and Atomic's datasheet and catalog give no instep number to check against. So have the shell checked with the liner out before you buy. Heat and punches can make room at a pressure point, but the shell stays low-volume.
If you are big and strong, question the flex. The bootfitter's 25/26 review lists the flex as a con, soft for its 130 rating, and points bigger skiers who want something beefier to Atomic's Remedy 130, a heavier boot on a narrower 96mm last. The reviewer, not a big person, found the flex fine, skied that 25/26 pair in late spring after making the shell-to-cuff connection more solid and swapping in their own liner, and thought the warm weather probably played a part. One fitter's impression is thin evidence, yet it is reason enough for a heavy, powerful skier to look at both.
Our call: the second dial earns its place if you will adjust the cuff during the day or want the more even flex. On the 25/26 boot, the bootfitter found the cuff dial quicker to adjust on the fly but the BOA dials slower than buckles to tighten, and stopped short of calling the Dual BOA setup a must-have while finding it takes nothing away from the boot's performance. It is no reason to give up a buckled Ultra that already fits.
Strengths
- +Two micro-adjustable BOA dials tune the lower shell and cuff separately
- +The cuff dial smooths the flex build-up, 25/26 reviews say
- +The Power Ankle Lock layer in the liner targets heel hold
- +Shell, cuff and liner can all be heat-molded
- +Power Shift gives three forward-lean settings, from 13° to 17°
Best For
Expert skiers whose shell check confirms a narrow, low-volume fit, who want the cuff on a dial too and plan on a heat fit.
Limitations
- −Most medium or wide feet will find this 98mm low-volume last tight
- −Tall insteps can make entry hard, a 25/26 review found
- −Sizes start at 25/25.5; Atomic's size run has no 24/24.5
- −A lift-served boot; Atomic's datasheet lists no walk mode
- −Tightening two BOA dials takes longer than closing buckles (25/26 review)
Not For
Most wide or medium-volume feet should start on a wider last: Atomic's Hawx Prime 130 S Dual BOA puts two BOA dials on the 100mm, medium-volume Prime last. Intermediates and advanced skiers who don't yet drive a 130 are better off in a softer boot. Anyone who skins uphill: Atomic's catalog list and datasheet mention no walk mode or tech inserts for it, while the Hawx Ultra XTD 130 BOA, made from 22/22.5 to 29/29.5, shares the 98mm last but adds tech inserts.
Common Questions
- What sizes does Atomic make the Ultra 130 S Dual BOA in?
- Atomic makes it in Mondopoint 25/25.5 to 30/30.5; the buckled Ultra 130 S and Ultra 130 S BOA start one size lower, at 24/24.5. Atomic's datasheet and catalog name no reference size for the 98mm width and give no instep height, so PTO sizes it from a measurement of your foot and a shell check done with the liner pulled.
- Will the Ultra 130 S Dual BOA fit my bindings?
- Atomic's 26/27 datasheet lists GripWalk ISO 23223 as the norm and Cantable GripWalk Grip Pads as the sole. Stepping into a binding doesn't prove the boot and binding are compatible, so ask a certified technician to check that sole against your binding.
- What changed on the Ultra 130 S Dual BOA for 26/27?
- Atomic lists no 26/27 changes on its page or in its catalog. The Black / Red boot still carries article code AE5033580, and Atomic's US page already showed that article as New in October 2025, with the same 1,896 g weight at 26/26.5 and the same 25/25.5 to 30/30.5 size run. That is why we read reviews of the 25/26 boot as reviews of this one.
- How stiff is the Ultra 130 S Dual BOA?
- Atomic gives it a 130 flex and, of its Beginner, Advanced and Expert skill levels, marks only Expert. That 130 is Atomic's own number, so compare it with other Atomic boots rather than another brand's 130. Power Shift can alter the flex as well as the lean, Atomic says, but its datasheet and catalog put no number on the change.
- Is the Ultra 130 S Dual BOA hard to get on?
- It can be, especially over a tall instep; a 25/26 review by a retailer's bootfitter advises widening the shell's throat as you slide in. On this version, the same 25/26 review explains, you lift the cuff cable off its upper pulley with a nylon tab to get in, then hook it back on and dial it tight. Atomic's product copy for this boot, on its pages from October 2025 to April 2026, says the AFS Tongue can be repositioned for different foot shapes and instep heights.
