2027 Nitro Sentinel Dual BOA® Snowboard Boot

Lock In. Step Up. Ride Everything.

Overview

Born from Nitro’s decades of snowboard boot expertise, the 2027 Sentinel Dual BOA® is built for riders who want a high-performance fit they can trust from first chair to last. Whether you are laying down carves on fresh groomers, lapping the park, or exploring off-piste, this boot delivers the effortless control and confidence you need to level up your riding.

The Sentinel is a durable, long-lasting investment engineered to eliminate foot distractions so you can focus entirely on having fun—all while keeping a lighter footprint on the environment.

Why it hits

• Dual BOA® Fit System: Dial in your perfect fit in seconds. The dual-zone configuration allows you to independently tighten the upper and lower zones of the boot for precise foot hold and zero pressure points.

• Low Profile Real Rubber Outsole: Engineered for maximum board feel and traction. This low-profile sole keeps you close to your deck for instant response while utilizing recycled rubber where possible to reduce waste.

• Interlock System: Say goodbye to heel lift. This internal design locks your liner's heel firmly into place, translating your foot movements directly to your board for effortless edge-to-edge control.

• Eco-Conscious Construction: Ride cleaner with a boot built using Zero PVC and 6P Phthalates, packaged completely in Plastic-Free Packaging.
