Nidecker set out to make their lightest ever snowboard boot, while sacrificing nothing in comfort or riding feel. The result is the Sierra. It's a progression-friendly model with a soft flex that delivers unbeatable bang for the buck – including BOA® lacing, an EVA Gravity outsole and an asym shell that perfectly matches the shape of Nidecker's bindings. Inside, a heat-moldable Bronze Level liner and single density footbed will keep your feet super comfy from day one.

LACING

• Single-Dial BOA®: A single BOA® dial located on the tongue tightens a steel lace across the entire shell. It's the quickest, simplest way to close and release your boot.
• H4 Coiler: Ready for anything, designed to withstand. The bombproof BOA® H4 Coiler is built for the most demanding riders and resists impacts from park to pow. Its efficient mechanism rapidly takes up lace slack, increasing speed of entry.

UPPER

• ASYM 3F: A unique asymmetric boot design co-developed with BOA® that generates optimal support and flex. The asym tongue features lace guides positioned on the flatter forefoot areas for more even closure and less point-loaded pressure. Increased medial arch support reduces foot fatigue and cramps.
• Articulating Flex Zone: The upper boot cuff is asymmetrically connected to the lower boot, allowing the ankle to flex naturally and providing great support without shell distortion.

LINER

• Bronze Level: This liner has an integrated lacing system for consistent tightening, and a new lace lock system which is simple & low profile. Intermediate volumes around the ankle ball prevent heel lift. The Custom Flex Zone at the toe guarantees comfort and freedom of movement in the toebox. 8mm of PE foam guarantees excellent overall comfort, and you can heat-mold it for a great fit.
• 3D Liner Support: Awesome foot hold that starts right inside the liner, with 3D molded material and J-bars around the ankle. Minimal movement, maximum control.
• Liner Lacing: The inner lacing system is located on the liner itself.

SOLE

• Gravity Outsole: Constructed from a single piece of bombproof and lightweight EVA, our standard Gravity outsole delivers great cushioning underfoot and a tread pattern that's similar to our high-end boots.
• 3D Single Density Insole: Anatomically designed to cradle your foot and constructed from a single piece of comfortable EVA. A fleece-lined footbed with silicone top-print keeps you warm and secure.
