Description
The Atomic Hawx Prime 100 BOA is a medium-volume all-mountain alpine boot on a 100mm last, and it is the softest, most accessible rung of Atomic's Prime BOA line. The lower shell closes with a BOA H+i1 dial in place of the two forefoot buckles, drawing the forefoot snug rather than clamping at two spots; two aluminum buckles still hold the cuff. That makes it a dial-below, buckle-above boot — not full BOA, and not a three-buckle design. Shell and cuff are polyurethane and heat-mold under Memory Fit, and the Mimic Silver liner molds too, so a fitter can work tight spots into a real fit.
Flex 100 is the point of this boot: supportive for an intermediate-to-advanced skier working across the whole hill at a real pace, but soft enough to give under a heavier, harder-charging one. On a prior-generation Prime 100, reviewers found the flex started to fold when they popped and landed kickers — that is the honest ceiling. It is a fixed 100mm medium-volume last, too: narrower feet belong in the 98mm Hawx Ultra, wider feet in the 102mm Hawx Magna, and the dial tightens tension without changing shell width. Skiers who want more cuff push-back step up to a stiffer flex — the 110, 120 or 130.
The sole is a GripWalk (ISO 23223) grip pad, so it needs a GripWalk or MultiNorm (MNC) binding rather than a plain alpine ISO 5355 one. There is no walk mode; skiers who want to skin uphill look at the Hawx XTD line. We fit these in the shop: we heat-mold the shell and liner, size you by shell fit rather than your street-shoe number, and have a technician confirm the sole against your binding and test the release. One honest note — the published on-foot reviews are of the prior generation, so read the ride impressions as platform-level, not as a test of the 26/27.

Flex 100
StiffLast Width
100mm— Medium (100–101mm)
Atomic's Hawx Prime 100 BOA is the softest, friendliest entry to the Prime BOA line: an all-mountain resort boot on a medium-volume 100mm last, closed by a BOA dial on the lower shell and tuned to a flex of 100. The dial replaces the two forefoot buckles with one micro-adjustable pull that wraps the foot evenly instead of clamping at two points. Two aluminum buckles still close the cuff, so read this as a BOA-lower boot — not a full-dial one, and not the three-buckle boot some shoppers picture.
Fit comes first, and the Hawx Prime 100 BOA runs on Atomic's 100mm medium-volume last — the middle of the Hawx trio. Narrower feet want the 98mm Ultra, wider feet the 102mm Magna, and the dial fine-tunes tension without changing shell volume, so a wrong-volume foot is not something BOA fixes. What it does buy is customization: Memory Fit lets you heat-mold the shell and cuff, the Mimic Silver liner is fully moldable with an Ankle Lock heel, and a 3D Stretch Toe Box gives a fitter room at the toes. Plan on a fitting session — out of the box is a starting point.
Flex is where the Hawx Prime 100 BOA draws its line. The 100 sits at the soft, accessible end of the Prime line, aimed at an intermediate-to-advanced skier with room for a strong intermediate to grow into. The trade is support at the top end: a prior-generation Prime 100 was described as beginning to fold a little easily when popping and landing kickers, so read that as the platform's ceiling — this is not a charger's boot. A heavier or harder-charging skier who wants the cuff to push back moves up the Prime line to a 110, 120 or 130 — and the S models among those add premium Gold or Platinum liners and adjustable Power Shift lean, which the flex 100 does not have.
The Hawx Prime 100 BOA rides on a cantable GripWalk (ISO 23223) sole, which walks and rolls far better than a flat alpine sole and can be planed for canting by a fitter — but it needs a GripWalk, MNC or MN-compatible binding, not a flat-only ISO 5355 alpine binding. Have a certified technician confirm the match and set and test the release; that is not something to read off a web page. There is no walk mode — touring is the separate Hawx XTD line. At 1,889 g per boot it is about 58 g lighter than the 1,947 g buckle Prime 100, which is the same boot with a traditional four-buckle closure.
Our position: the Hawx Prime 100 BOA gives you a genuinely comfortable, modern entry to a BOA closure and a GripWalk sole, best for a medium-volume intermediate-to-advanced skier who will get it molded, and worth buying for what it is rather than for a stiffness it does not have. The ride impressions here are platform-level, drawn from prior-generation and sibling reviews.
Strengths
- +BOA H+i1 lower wraps the forefoot evenly — no two-point buckle clamp
- +Memory Fit shell and cuff plus a fully moldable Mimic Silver liner
- +About 58 g lighter per boot than the buckle Prime 100
- +Cantable GripWalk (ISO 23223) sole walks better than a flat alpine sole
- +Fast one-hand dial entry; comfortable before any molding
Best For
Medium-volume intermediate-to-advanced skiers who ride the whole mountain at a real but not race pace, want an even BOA wrap over the forefoot, and will have the shell and liner heat-molded for a real fit.
Limitations
- −BOA lower plus 2 cuff buckles — not a full-dial boot
- −Flex 100 folds under aggressive input; not a charger's boot
- −Fixed 100mm medium-volume last — the dial can't change width
- −No walk mode — touring is the Hawx XTD line
- −Ride feel is read at platform level across the Hawx Prime line
Not For
Narrow, low-volume feet (that is the 98mm Hawx Ultra) and wide, high-volume feet (the 102mm Hawx Magna) — the BOA tightens tension, it does not change the shell's width. Heavier or aggressive skiers who charge hard or land big kickers and want the stiffer 110, 120 or 130. Anyone who needs a walk mode for touring, which is the Hawx XTD line, not this fixed-cuff resort boot. And flex-number shoppers: a flex index is not standardized across brands, and last width and real fit matter more than the number.
Common Questions
- What is the difference between the Hawx Prime 100 BOA and the buckle Hawx Prime 100?
- Both share the same 100mm medium-volume last, flex 100, Energy Link cuff, Mimic Silver liner and GripWalk sole. The BOA version swaps the two lower buckles for a BOA H+i1 dial that wraps the forefoot evenly and micro-adjusts, and it comes in about 58 g lighter per boot. The buckle version is the traditional four-buckle closure.
- Is the Hawx Prime 100 BOA good for wide feet?
- It is a medium-volume boot on a 100mm last, so it suits an average-width foot best. Wide, high-volume feet are better served by the 102mm Hawx Magna. A fitter can heat-mold the shell and the 3D Stretch Toe Box to relieve specific pressure points, but molding adjusts a fit — the dial and shell will not turn a medium last into a wide one.
- What bindings does the GripWalk sole work with?
- The Hawx Prime 100 BOA has a GripWalk (ISO 23223) sole, which pairs with GripWalk, MNC (MultiNorm) or MN-compatible bindings. It will not sit correctly in a flat-only ISO 5355 alpine binding. Have a certified technician confirm compatibility and set and test the release before you ski it.
- Is the Hawx Prime 100 BOA a beginner boot?
- No. Flex 100 is aimed at intermediate-to-advanced skiers — accessible to all but true beginners, with room to grow into. Heavier or harder-charging skiers who want more support should look at the stiffer 110, 120 or 130 in the same Prime line.
