Description
The Atomic Hawx Prime 100 is a 100 flex all-mountain ski boot on a 100mm medium-volume (MV) last — the softest, most forgiving boot in Atomic's four-buckle Hawx Prime range, built comfort-first and finished by a bootfitter. The flex is Atomic's own house number, not a cross-brand figure. It suits intermediate to cruising-advanced skiers who ski the whole hill at a moderate pace rather than charging it.
Construction is Atomic's Prolite: a PU shell and cuff, streamlined where it can be and reinforced where it drives the ski. Both the shell and the cuff are heat-moldable (Memory Fit), and so is the Mimic Silver liner, which is pre-shaped around the heel and ankle and adds a Hawx Fixed Tongue and a 3D Stretch Toe Box. Four aluminum buckles and a Velcro power strap close it; an Energy Backbone and Energy Link add rearward support and turn snap without stiffening the forward flex.
This is a true medium boot, so foot shape does the routing. A truly narrow foot swims a little here and is happier in the narrower Hawx Ultra; a wide or high-instep foot wants the wider Hawx Magna. And because it carries the range's softest flex, a hard-charging skier will fold it — the stiffer, higher-flex Prime models are built for that. Memory Fit refines a fit; it will not rebuild the last, and this is not a touring boot.
Atomic calls the 26/27 a season update without detailing the changes, so treat it as a refresh, not a redesign; it sells for $550. There is also a BOA-closure version on the identical last and flex, which trades the lower buckles for a dial if you prefer that wrap. One thing to settle before skiing: the soles are GripWalk (ISO 23223), which belong in a binding built or certified for GripWalk — a Multi-Norm (MNC) model — not a standard alpine ISO 5355 binding, and a certified technician should confirm that match before the boots are skied. In the shop we measure your feet, heat-mold the shell and liner, and check the sole against your bindings.

Flex 100
StiffLast Width
100mm— Medium (100–101mm)
The Hawx Prime 100 sits at the entry of the four-buckle Hawx Prime line — the easiest-bending, most forgiving of the four-buckle boots, built around a genuine 100mm medium-volume (MV) last. It rewards long resort days and a proper bootfitting session; it is not a boot for skiing at the red line.
On feel, two honest caveats come first. Atomic tags the 26/27 Prime 100 “lifted” — a season update rather than a straight carry-over — but does not publish what changed, so read no specific redesign into it. The clearest tester impression comes from an earlier-generation Prime 100, described as a plush foot-hug — comfortable from the first run, even without a custom footbed — that begins to fold once you push it hard off kickers and heavy landings. Read that as direction consistent with a soft flex, not a verdict on this season’s boot.
What $550 buys is the entry rung of the Prime range, and the spec sheet is honest about it. You get the Mimic Silver liner rather than the Gold or Platinum of the stiffer S models, a fixed forward lean rather than their adjustable-lean system, and the Energy Link connector rather than the S models’ energy system. The reward is a friendlier flex and heat-moldable comfort; the trade is top-tier cuff power and stance adjustability.
The closest decision is the closure. The Hawx Prime 100 BOA rides on the same 100mm last at the same 100 flex, but trades the two lower buckles for a BOA dial and costs $665. We make no claim that one skis better than the other: four aluminum buckles give serviceable, zone-by-zone tension, while the dial wraps the lower foot more evenly, in micro-adjustable increments. This is a fit-preference call on the same last and flex, not a performance upgrade.
Fit routing is the rest of the story. That 100mm last is a true medium — the middle of Atomic’s Ultra, Prime and Magna ladder — so a genuinely narrow foot sits roomy in it and a wide foot sits tight. Memory Fit heat-molds the shell and cuff, and the liner molds around the heel, which finishes a fit but does not rebuild the last. And the sole is GripWalk, stamped ISO 23223: it has to run in a binding that accepts a GripWalk sole — a Multi-Norm unit, or one certified for GripWalk — and not a plain alpine ISO 5355 binding. Get that pairing set and tested on a machine by a certified technician before these are skied.
Strengths
- +Memory Fit heat-molds the shell and cuff; the Mimic liner molds around the heel too
- +Comfortable straight out of the box, with the softest flex in Atomic’s Prime line
- +GripWalk soles (ISO 23223) with replaceable, canting-adjustable grip pads
- +A current-generation, heat-moldable all-mountain boot at $550
Best For
Intermediate to non-aggressive advanced all-mountain skiers with a genuine medium-volume (~100mm) foot who want out-of-the-box comfort, a forgiving flex they can ski all day, and a boot a fitter can heat-mold to finish the fit in the shop.
Limitations
- −Folds under hard, aggressive or high-speed input — this is not a charger
- −Entry Prime tier: comfort and forgiveness, not top-tier cuff power or adjustable lean
- −A true medium last — narrow feet sit roomy, wide feet sit tight
- −No walk mode; GripWalk is a sole, not a hike mode
Not For
Hard chargers and high-speed experts: 100 is the softest flex in the Prime line, and testers of the older-generation Prime 100 found it folds under aggressive input — a skier who drives the cuff wants the stiffer Prime 110 or 130 on the same 100mm last. Absolute first-timers, who are usually better served by a softer boot. Genuinely narrow feet, which sit roomy in a 100mm medium last and belong in the lower-volume Hawx Ultra; and genuinely wide or high-instep feet, which belong in the roomier Hawx Magna — Memory Fit molds a shell, it does not turn a medium last into a narrow or wide one. Skiers set on the even, dialed-in wrap of BOA, which is the $665 Hawx Prime 100 BOA on the same last and flex. Touring skiers who need a walk mode, since this is a fixed-cuff alpine boot. And anyone planning to drop these into bindings they already own without a technician: the GripWalk sole has to be matched to what the binding accepts.
Common Questions
- What is the difference between the Hawx Prime 100 and the Hawx Prime 100 BOA?
- Closure and price. Both ride on the same 100mm medium last at the same 100 flex, but this boot uses four aluminum buckles while the Hawx Prime 100 BOA swaps the two lower buckles for a BOA dial, at $665 against $550. We make no claim that either skis better: the buckles give serviceable, zone-by-zone tension, and BOA gives a more even, micro-adjustable wrap of the lower foot. Choose on fit preference, not performance.
- Will the Hawx Prime 100 work with the bindings I already own?
- Only if that binding accepts a GripWalk sole. This boot ships GripWalk soles (ISO 23223), which need a GripWalk-certified or Multi-Norm (MNC) binding; a conventional alpine ISO 5355 binding without GripWalk certification will not take them. Have a certified technician confirm the boot-and-binding match and set your release on a machine before you ski.
- Is the Hawx Prime 100 a beginner boot?
- Not quite. The 100 flex is the softest in the Prime line, but reviewers put it past the true-beginner stage, so a first-timer is usually better in a softer boot. It suits progressing intermediates and cruising advanced skiers; a stronger, more aggressive skier who drives the cuff should look at the stiffer Prime 110 or 130 on the same last.
- Is the Hawx Prime 100 good for wide feet?
- No. The 100mm last is a true medium, not a wide fit. A genuinely wide or high-volume foot belongs in the roomier Hawx Magna, and a narrow foot in the lower-volume Hawx Ultra. Memory Fit can heat-mold the shell to ease pressure points, but molding adjusts a fit — it does not turn a medium last into a wide one. Get shell-fitted before you commit.
