Boot Type: Advanced All Mountain
Boot Flex (1 = Soft / 10 = Stiff): 9-10/10
Lacing System: Dual Boa
The Double Boa lacing consists of two independent zones, controlled by two separate laces allowing you to customise your fit with ease, and get in and out of your boot in record time.
Liner: Cloud 9 Liner
The Nitro Cloud 9 Liner is one of the best liners from Nitro, with a lightweight, supportive fit that will blow almost any other liner out of the water. All Nitro liners are heat mouldable, and while it isn't necessary, a heat mold can give you a more custom fit from day 1 as opposed to wearing the boot in. The Cloud 9 Liner comes with a triple-density Ortholite Footbed, which offers superior shock absorption and energy return with minimal compression, so your footbed will perform consistently for the entire life of your boot. It is also quick-drying, extremely lightweight, and has an anti-microbial coating, making your boots smell better, feel better, and last longer.
ILS Liner Lacing
The Nitro ILS Liner Lacing system features a lacing harness directly connected to the boot shell that snugly wraps around the liner, firmly securing it in the shell for strong hold and a precise fit.
Re/Lace Liner Locker
The Re/Lace Liner Locker revolutionizes how a liner lace functions. During a day of snowboarding, your boots are going to loosen. Your foot settles, your boot expands, it happens. With the Re/Lace Liner Locker, once the laces are locked in at the start of the day all you need to do is pull the liner lace tab to retighten your liner, without ever needing to undo your boots.
Therminator Shield
The Therminator Shield is a thin thermal layer between sole and liner that reflects heat back into your boot, keeping your feet warm all day.
Ortholite High Cup Triple Density Footbed with O-Therm
Ortholite is the worlds leading supplier of open-cell foam insole technology. Ortholite compresses less than 5% with excellent levels of shock absorption and energy return. It also has a unique open cell structure that wicks moisture away, dries quickly, and contains a patented anti-microbial formulation to fight fungus, bacteria and odour. This lightweight technology provides optimum performance without adding excess weight to the boot.
Cushioning / Traction: Step On Rubber Sole
This outsole is composed of an EVA midsole, which reduces weight, increases impact absorption, and aids in heat retention and the Burton Step On Rubber Sole has an effective traction pattern, with an abrasion resistant, grippy rubber sole that provides durability, grip and insulation.
Additional Features:
Internal Ankle Support
This internal ankle support system puts an anatomically moulded plate over the top of your ankle, evenly distributing lace pressure and giving you a more precise fit.
Power Tongue Stiffener
This removable piece adjusts the stiffness of your tongue, and in turn, the response of your boot. Add it in for more aggressive turns and quicker response, or take it out for a little more freedom and a more relaxed ride.
