Step One In Progression The Nitro Droid QLS snowboarding boot is the first step in progression for kids looking for the response and technology to progress every day, with a perfect and easy-to-use fit. The Nitro Droid QLS snowboard boot was developed specifically for those first-time shredders, those young rippers who put the rest of us to shame, and the kids who demand more than a kids boot! The Droid QLS features the QLS Lacing System, Interlock Cloud Liner, and a Removable Light Liner to allow for a custom foothold. At the same time, the Powerstrap provides for the perfect adjustable response. Built with all the support and fit technologies of our pro-level boots, this ripper-friendly quick lacing (QLS) snowboard boot will get you first out of the lodge and on the chair faster all season long! Good long days on the mountain all start with comfortable feet.
