Nitro Women's Cave TLS Step-On Snowboard Boots 2025 | Lilac

The Cave TLS Step On® is something special. It represents the kind of progression that only happens when two technology-focused R&D departments put their best thinking in the same room — the result is the best-fitting, most convenient snowboard setup you will ever experience. Nitro's boot-building know-how, refined over decades of obsessing over fit and liner technology, meets the ground-breaking quickness of the Step On® interface for a combination that lets beginners through to pros get more runs in regardless of the conditions. Click in and go. Every run. All day. The TLS Twin Lacing System is Nitro's most developed dual lacing system — two independent zones on specifically designed, low-abrasion Dyneema® laces, proven reliable by tens of thousands of days on the mountain. The new Ankle Strap with BOA® is precisely designed to fit the boot's shape and deliver the support experience and feel of a binding ankle strap, adding a further layer of heel hold and ankle security. The Women's Cloud 9 liner is Nitro's most ergonomic design ever — heat-mouldable, ILS-locked to the shell, and shaped specifically for the female foot for immediate comfort and a fit that stays dialled all day. The patented Re/Lace Liner Locker means retightening your liner mid-session is a single pull away without ever undoing your boots. If your focus is fit, comfort, and the unmatched quickness of the Step On® interface, this is the boot you step into.

TLS Twin Lacing System
Nitro's most developed dual lacing system and the benchmark for twin lace technology in snowboarding. Two independent lacing zones tighten quickly and lock safely in place via a compact, lightweight mechanism proven reliable by tens of thousands of days on the mountain. Specifically designed, low-abrasion Dyneema® laces run both paths — stronger and more durable than standard textile laces with a smoother, more consistent tightening feel. Easy-entry handle storage pockets keep the handles out of the way when not in use, and the Bail Out system allows effortless lace release at day's end with a single pull.

Ankle Strap with BOA®
Nitro's new ankle strap with BOA® is precisely designed to fit the boot's shape and deliver the support experience and feel of a binding ankle strap — directly integrated into the boot. The BOA® dial provides micro-adjustable control over the ankle zone on the fly, adding additional heel hold and ankle support on top of everything the TLS system and ILS harness already deliver. It's the detail that makes the Cave feel unlike any other boot on the market.

ILS Internal Lacing System + Patented Re/Lace Liner Locker
The ILS Internal Lacing System uses an internal harness to lock the liner firmly to the shell — eliminating heel slip and keeping the liner secured in place from first run to last. The patented Re/Lace Liner Locker works alongside it: once the liner laces are set at the start of the day, retightening mid-session is a single pull of the liner lace tab — no undoing boots, no removing gloves, no interruption to your day. Easy and precise liner lacing, all day long.

Step On® Outsole
The Step On® interface is built directly into the outsole — three connection points click into compatible Step On® bindings for instant, secure engagement every run. No straps, no buckles, no fussing at the bottom of the lift. Step in, click, ride. Step out at the end of the day just as fast. The Nitro Step On® outsole uses up to 30% recycled rubber content for reduced environmental impact, with an effective tread pattern for grip, durability, and thermal insulation underfoot.

Women's Cloud 9 Liner
Nitro's most ergonomic women's liner design ever. The heat-mouldable Cloud 9 wraps your foot with a lightweight, supportive construction shaped specifically for the female foot — out of the box it already fits with precision and purpose; heat mould it in-store and it conforms exactly to your foot's contours for a fully custom fit with zero pressure points. Locked to the shell via the ILS Internal Lacing System throughout the day, the Cloud 9 stays exactly where it's supposed to be from first chair to last run.

Therminator Shield
A reflective thermal layer built between the sole and liner that reflects body heat back into the boot — keeping your feet warm through cold lift rides, early-morning starts, and long days in variable conditions. Sole insulation that works passively all day without any input required.

Ortholite® High Cup Dual Density Women's Footbed
Ortholite®'s women's-specific dual-density footbed delivers superior cushioning, support, and energy return with a high cup design that cradles the heel and arch for all-day stability. Open-cell foam wicks moisture and dries quickly between sessions, the anti-microbial coating fights bacteria and odour, and the minimal-compression construction maintains its cushioning and support consistently across a full season of hard use.

Frequently Asked Questions:
Do these boots work with my current bindings?
No — the Cave TLS Step On® is compatible with Step On® bindings only. It will not work with traditional strap bindings. Boot and binding sizes also need to match correctly for proper Step On® engagement and performance. If you're building a complete Step On® setup, our staff can confirm the right boot and binding size combination before you order. Call us on 03 9421 2293 or message through the contact page.

What size should I order?
The Nitro Cave TLS Step On® runs true to women's US shoe size. Snowboard boots should feel snug straight out of the box: toes lightly grazing the front of the liner when standing upright, heel locked down with minimal lift. Drop into a riding stance and the heel drops — that's the correct fit. Because Step On® boot and binding sizes must match for correct engagement, confirm your size combination before ordering. Our full boot fit guide is at twelveboardstore.com.au/pages/snowboard-boots-how-to-choose-and-fit-guide, or call us on 03 9421 2293 and we'll confirm the right combination for you.

Do you offer professional boot fitting and heat moulding?
Yes — and it's free when you buy your boots from us. Come into the store at 435A Bridge Rd Richmond and our staff will fit you properly: measuring your foot, checking shell fit before the liner goes in, and heat moulding your Cloud 9 liner to your exact foot shape on the spot. With a boot this technical — TLS dual-zone lacing, ILS harness, BOA® ankle strap, Step On® outsole — getting the setup right in person makes a real difference to how it performs from day one. Not in Melbourne? We can walk you through the at-home process by phone or message.

What if I get the wrong size or the fit isn't right?
Reach out before you do anything else — call us on 03 9421 2293, message through the contact page, or email info@twelveboardstore.com.au. The Cave's dual-zone TLS, BOA® ankle strap, ILS system, and Re/Lace Liner Locker give meaningful fit adjustability, so many apparent fit issues can be resolved without a return. If the boot genuinely isn't right for your foot, we'll swap it. Boots must be unworn outside — lodge floors and carpet only — and returned in original condition.

From the beginning, Nitro built their boots from the inside out, prioritising fit and liner technology above everything else — and that philosophy drives every product they make.

Nitro's sustainability commitments include eliminating PVC and harmful plasticisers across their product range, using recycled rubber in outsoles, and plastic-free packaging throughout.
