Rome 390 Boss AW
390 Boss family · 2026/27
Terrain
Flex
Mid — Rome's nominal 6/10; the catalog flex bar sits in the 5-6 band
Flex ratings are the brand’s own and do not compare across brands.
Rome builds the 390 Boss with three different heelhoop platforms — the FullWrap, this AsymWrap, and the HeelWrap — bolted to one common baseplate and set of hardware. The platform is the whole difference between the three: Rome sets each one apart by how many connection points its heelhoop makes to the baseplate — two on the HeelWrap, three on this AsymWrap, four on the FullWrap — and that is what decides the flex and how the binding answers back. The highback is a separate part here; the real choice is which of the three heelhoop wraps you want under your heel, and the AsymWrap is the one in the middle.
On Rome's own scale that is a 5-6 flex, sitting between the stiffer FullWrap at 6-7 and the softer HeelWrap at 4-5. Rome describes the AsymWrap as its surfy yet responsive platform, built for board feel and tweakability, and the flex number lines up with that: enough spine to hold a turn, enough give to press and butter without the binding fighting you.
Rome's own headline for the AsymWrap is an all-terrain 'party lapper.' Read it as an all-mountain, freestyle-leaning tool rather than a specialist — a binding for the rider who laps the park, hits the side features on the way down, and keeps the same setup on for the groomers after. It is not the one you reach for if your day is mostly pinning it on steep, chattery hardpack; that is the FullWrap's job.
Two things pull riders off the AsymWrap, and both point at a sibling. If you charge — high speed, deep landings, tweaks you want to land locked in — the FullWrap is the stiffer chassis Rome built for exactly that. If you are newer, or just want the softest, most forgiving flex to ride all day, the HeelWrap is mellower. The AsymWrap earns its place only if you genuinely want the middle: response without rigidity, forgiveness without mush.
Two honest notes before you buy. Rome's flex figure is its own marketing number, not a measured stiffness, and we have not ridden the 26/27 AW — everything above is read from the platform and the flex, not from laps on snow. And Rome does not publish a weight for the 390 Boss, so if grams are part of your decision, ask us and we will weigh a pair. Bring your boots too: binding size follows the boot, and we confirm the disc in the box against your board before you ride.
Will it fit your board?

Technology
AsymWrap platform
Rome's own line for it: a surfy yet responsive platform, designed for board feel and tweakability. It is the middle of three heelhoop platforms (wraps) on the 390 Boss — Rome's binding-tech page sets each one apart by how many connection points the heelhoop makes to the baseplate, and this AsymWrap runs three (the FullWrap four, the HeelWrap two). The highback is a separate part. Beyond that Rome prints no deeper mechanism, so that is all we state about it.
Kink Ladders
Rome says the Kink Ladders give two additional ankle-strap positioning options — more room to set where the ankle strap sits. Rome names the part and this function; it prints nothing further, and we invent nothing.
Mounting disc
Rome does not publish which insert pattern the disc fits. Independent specs point to the usual shared 390 Boss disc, which covers 2x4, 4x4 and Burton's Channel, but since Rome does not confirm it we treat the pattern as unpublished and check the actual disc against your board before you ride.

Strengths
- +The middle wrap: more response than the HeelWrap, more give than the FullWrap.
- +Same baseplate, straps and footbed as the FullWrap — the heelhoop platform (wrap) is what changes.
- +Kink Ladders add two ankle-strap positions for dialing the fit.
- +Rome's surfy, tweakable platform: board feel without going full-soft.
Best For
One-binding, do-everything riders — intermediate to advanced — who lap park and side features and then take the same setup onto groomers, and want response and board feel without a rigid, chargey feel.
Limitations
- −Rome's flex is a marketing number, not a measured stiffness.
- −No published weight from Rome; grams are unknown until we weigh a pair.
- −Not ridden by us — a spec-and-platform read, not a ride report.
- −Mount pattern comes from a third-party spec, not Rome's own page — confirm the disc.
Not For
Chargers who want maximum locked-in hold at speed and on deep landings — that is the stiffer FullWrap. First-timers and mellow cruisers who want the softest, most forgiving, most hassle-free flex — that is the HeelWrap. And anyone who needs an official weight on paper before buying: Rome does not publish one for the 390 Boss.

Common Questions
- What's the difference between the Rome 390 Boss AW, FW and HW?
- All three are the same binding with a different heelhoop platform (wrap) on one shared baseplate — Rome sets them apart by how many connection points the heelhoop makes to the baseplate. The AsymWrap (AW) is the middle, with three connection points: mid flex, surfy but responsive, aimed at all-mountain freestyle. The FullWrap (FW) has four, stiffer and more locked-in for charging and deep landings. The HeelWrap (HW) has two, the softest and most forgiving. Pick by the flex and feel you want.
- Will the 390 Boss AW fit my board?
- Rome does not publish which insert pattern this binding's disc fits, so we do not assert one. Independent specs report the usual shared 390 Boss disc, which covers 2x4, 4x4 and Burton's Channel, but because Rome does not confirm it, we check the actual disc in the box against your board before you ride.
- How do I size Rome bindings?
- By your boot, never your weight or height. We stock the 390 Boss AW in M/L and L/XL. Bring the boots you will ride and we will match the binding and set it up.
- What does the 390 Boss AW weigh?
- Rome does not publish a weight for the 390 Boss line. If weight is part of your decision, ask us and we will put a pair on the scale before you commit.
