Description
The Hawx Ultra 130 S BOA from Atomic is a narrow, low-volume alpine ski boot for expert skiers who want a BOA dial on the shell. Atomic builds it on the 98mm Hawx Ultra last with a 130 flex, lists it at 1,861 g per boot at 26/26.5, and makes it in Mondopoint sizes 24/24.5 to 30/30.5.
Atomic swaps two shell buckles for a BOA H+i1 Single Pull dial, which tightens or loosens the wrap in small steps either way. Atomic's catalog also lists 6000-series aluminum buckles and a 40/45mm Cam Strap, a non-elastic strap that Atomic says gives direct energy transfer. The PU shell and cuff use Atomic's Prolite construction, light overall with key structural areas reinforced, and Energy Backbone adds reinforcement that Atomic credits with extra strength and edge grip.
Memory Fit lets a bootfitter heat the shell and cuff and reshape them to your foot and leg. The Mimic Platinum liner carries heat-moldable material in its pre-shaped heel, ankle and tongue, and Power Ankle Lock, a dense, asymmetrical liner layer, contours the ankle to hold the heel.
It suits an expert with a narrow, low-volume foot who skis groomers and all-mountain terrain hard and will have the boot heat-fitted. Medium-volume and wide feet are not what Atomic built it for. It expects a skier strong enough to flex a 130 rated for experts. Atomic lists no walk mode for it.
The sole is GripWalk ISO 23223 on cantable grip pads, so have a technician confirm your binding against that sole before the boots go into it.
At PTO we shell-check your foot, heat-fit the shell and liner, and check the boots against your bindings.

Atomic Hawx Ultra 130 S BOA
Hawx Ultra family · 26/27BOA
Flex 130
Very StiffLast Width
98mm— Narrow (96–99mm)
The 130 S BOA is a narrow-foot boot first and a BOA boot second. Its 98mm narrow, low-volume last decides whether it works for you; the dial and the 130 flex come after. Heat molding can relieve a pressure point. It will not turn a low-volume shell into a medium-volume one. Start with a shell check, liner out, and settle the instep question there.
Tall insteps are the risk to rule out. Atomic publishes no instep figure. The nearest guide is a bootfitter's review of the 25/26 Ultra 130 S Dual BOA, which Atomic lists on the same 98mm last, and it warns that the narrow Ultra cuffs make getting in and out difficult for some people, particularly those with tall insteps. Get past that and the heel is the payoff, with Power Ankle Lock there to hold it.
One 98mm last, one 130 flex, three closures. The Ultra 130 S uses four buckles, this boot puts one H+i1 dial on the shell and keeps aluminum buckles, and the Ultra 130 S Dual BOA runs two dials, with no buckles in its catalog entry. Their 26/27 datasheets differ only in weight, listed per boot at 26/26.5 as 1,896 g for each sibling and 1,861 g for this one, with no reason given. A gap that small should not decide it. The way you like to close your boots every morning should.
Read the flex number with care. The 130 sits on Atomic's own scale and the boot is rated for experts, so judge it against other Atomic boots. Skiers who want a narrower, heavier boot at the same 130 rating can look at the Remedy 130, which Atomic builds for aggressive freeskiers on a 96mm last and lists at 2,312 g for one 26/26.5 boot, against this boot's 1,861 g.
Uphill is where it loses outright. There is no walk mode on Atomic's list, so skinning belongs to the Hawx Ultra XTD 130 BOA, which Atomic files under freeride touring. It keeps the 98mm last and adds investment-cast tech inserts. Keep the 130 S BOA for days that start at the lift, with a dial you can ease off on the chair and snug up again before the next run.
Strengths
- +Atomic's H+i1 dial micro-adjusts the shell's wrap in both directions
- +Power Ankle Lock makes heel hold this liner's strong point
- +The 3D Stretch Toe Box adds liner room at the big toe
- +Shell, cuff and liner are all heat-moldable
Best For
Expert skiers with narrow, low-volume feet who ski hard on groomed runs and all-mountain terrain, want the shell's wrap on a micro-adjustable dial, are happy to keep buckles on the boot, and plan to book a shell check and heat fitting.
Limitations
- −The 98mm low-volume last leaves little room for high-volume feet
- −On this low-volume shell, tall insteps need checking first
- −No walk mode is listed, so skinning uphill is out
Not For
Skiers with medium-volume or wide feet. For medium-volume feet, Atomic builds the Hawx Prime 130 S Dual BOA on a 100mm last. Intermediate skiers, and lighter advanced skiers who cannot yet bend a 130 that Atomic rates Expert. Anyone planning to skin uphill, because Atomic names neither a walk mode nor tech inserts for this boot.
Common Questions
- What size Atomic Hawx Ultra 130 S BOA should I get?
- Atomic makes this boot in Mondopoint, from 24/24.5 up to 30/30.5, and gives the 98mm last width without a reference size or an instep figure. On a narrow, low-volume shell, we size it by measuring your foot and checking the shell with the liner out.
- What bindings work with the Atomic Hawx Ultra 130 S BOA?
- Atomic lists the norm as GripWalk ISO 23223 and the sole as Cantable GripWalk Grip Pads. A boot that clicks into a binding is not proof the pair is compatible. A certified technician confirms your binding against the sole.
- Is the 26/27 Atomic Hawx Ultra 130 S BOA different from 25/26?
- Atomic publishes no change note for 26/27: the boot keeps article AE5032000 in Black / Red, which Atomic's US page already marked New in October 2025, and its listed weight stays at 1,861 g for size 26/26.5. Atomic's page text from October 2025 and January 2026 said the spoiler on the AFS Cuff could be removed to add calf volume, but the April 2026 page and the 26/27 catalog list name no AFS Cuff and say nothing about removing a spoiler. The catalog list does name a Dual Velcro Spoiler and a Liner Spoiler, without describing either, so whether a spoiler comes out on the 26/27 boot is unconfirmed.
- How stiff is the Atomic Hawx Ultra 130 S BOA?
- Atomic rates it 130 and lists it for expert skiers. A bootfitter who reviewed the 25/26 Dual BOA version found that boot's flex on the soft side for a 130, very slightly more forgiving than their old Hawx Ultra 130, and said the warm late-spring temperatures probably had an effect. The Dual BOA adds a second dial, so read that as a pointer for this boot, not a measurement of it.
- Can you adjust the forward lean and flex on the Atomic Hawx Ultra 130 S BOA?
- Yes. Power Shift sets the forward lean at 13°, 15° or 17°, with 15° as the default, and Atomic says it can also alter the flex. Atomic publishes no figure for how much the flex changes, and it lists the ramp angle at 4°.
