Nitro’s own 1–10 scale — a house number, not comparable across brands.

Nitro's Crown BOA is the comfort-and-fit end of its women's all-mountain lineup. Its flex is a medium, it closes with a two-zone BOA, and its liner is the heat-moldable Women's Cloud 6. Two lacing versions exist, and this is the dialed one.

The Crown BOA's case is comfort. The Cloud 6 liner molds to the foot with heat, ships with pre-molded Thermacell so it feels worked-in sooner, and rides on an Ortholite High Cup footbed; an internal lacing system laces the liner into the shell to keep the heel seated. Nitro builds it on a women's-specific fit — shaped for a woman's foot, not a unisex boot sized down.

The Crown BOA's closure is the Dual High Power H5 BOA system: two independent dials with a 4:1 mechanical advantage and a Coiler on the tongue dial. In plain terms, you set the lower and upper of the boot separately, and you can re-tune either one with a glove on partway down a run instead of stopping to re-lace. A rider who would rather pull a single speed lace than turn two dials wants the Crown TLS — the same women's boot with Nitro's speed lace.

The Crown BOA's flex is the part to be straight about. A Response rating of 5 out of 10 is a medium, and the Cloud 6 is the flexible liner in Nitro's range: it gives up some support to the stiffer Cloud 9 and 10 in exchange for board feel. That makes it forgiving to learn on and easy to skate, press and ride all day, but it is not a stiff, high-response boot for aggressive high-speed carving or big-mountain charging. A rider chasing that response should step up to a model built on the firmer liner. And a snowboard flex number is Nitro's own scale — it does not convert to another brand's.

The Crown BOA runs an EVA outsole, light and grippy, with rubber impact panels that use up to 30% recycled rubber, plus a molded toe box and a reinforced heelcup for wear. Note what a snowboard boot does not have: no walk mode, no sole standard, no release hardware — none of the ski-boot machinery applies here. We did not find an independent on-snow test of this exact boot, so this read rests on Nitro's specs and the Crown's long standing as a comfort-fit boot, not on a PTO ride. Get the liner heat-molded and the size confirmed in the shop; that is where a boot like this is set up right.

  • +Two-zone Dual BOA tunes the lower and upper separately, re-tunes mid-run
  • +ILS laces the liner into the shell to keep the heel seated
  • +Versatile medium flex — forgiving to learn on, ready to progress
  • +EVA outsole with recycled-rubber impact panels and a reinforced heelcup

Best For

Nitro states no ability grade, so this is PTO's read from the layup: beginner-to-advanced women who want one comfortable, versatile all-mountain boot and value dialed-in BOA fit and out-of-box liner comfort over outright stiffness.

Limitations

  • A comfort-first medium, not a stiff boot for aggressive charging
  • Cloud 6 is Nitro's flexible liner — less support than the Cloud 9 or 10
  • Nitro publishes no weight and no last-width figure for it
  • US women's sizing differs between Nitro's own two sources
  • No independent on-snow test found; the read is spec-based

Not For

Riders who want a stiff, high-response boot for aggressive carving or big-mountain charging — Response is a medium, and the Cloud 6 is the flexible liner. Riders who prefer a single speed-lace pull over BOA dials, who should look at the Crown TLS instead. And men or higher-volume feet, since this is built on Nitro's women's-specific fit.

Common Questions

Is the Nitro Crown BOA stiff enough for me?
It is a medium — Nitro rates it Response 5 of 10 and Comfort 9 of 10 — over the softer Cloud 6 liner. That suits a rider who wants comfort and all-mountain range from groomers to park. If you charge hard and want a stiff, high-response feel for fast carving or big-mountain lines, step up to a model with the firmer Cloud 9 or 10 liner.
Crown BOA or Crown TLS — what is the difference?
The same women's Crown, two closures. The BOA uses Nitro's Dual High Power system — two dials, one for the lower zone and one for the upper, with a Coiler on the tongue dial — so you set fit in sections and adjust on the move with gloves on. The TLS uses Nitro's speed lace, a single pull. Fit, liner and flex are the same; pick the closure you prefer.
What sizes does the Nitro Crown BOA come in, and how should I size it?
Nitro runs it from 22.0 to 28.5 Mondopoint. The US women's labeling differs between Nitro's own two sources, so go by Mondopoint and the size selector rather than your street-shoe number, and get the boot fitted — the Cloud 6 liner heat-molds, so a proper fit is part of the setup.
Is the Crown BOA a women's-specific boot?
Yes. Nitro builds it on a women's-specific fit — a shape meant for a woman's foot, not a unisex boot sized down — and the Women's Cloud 6 liner keeps that fit with heel hold and comfort. A men's or higher-volume foot should look at a different last. Nitro does not publish a millimeter last width for its snowboard boots, so treat fit as something to confirm in person, not read off a number.
