Convenience and Comfort 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 bindings. Inside, a heat-moldable Bronze Level liner and single density footbed will keep your feet super comfy from day one. Key Features The Sierra's BOA® Fit System closes the whole boot at the twist of a dial; TX3 textile laces give a more natural feel while reducing weight. Like all our boots, the Sierra delivers a precise fit via 1:1 lasting, which means a specific shell, liner and footbed for every full and half size. The relaxed flex delivers all-day comfort and is ideal for mastering turns and venturing into the park.Lacing + LinerSINGLE DIAL BOA® CONFIGURATION - The single-dial BOA® configuration offer substantial support and a fabulous fit, within seconds, while remaining as comfortable, forgiving and easy-to-use as ever. H4 Dial - Ready for anything, designed to withstand. H4 resists impact from the most demanding rider. Tried and true. 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.Construction + MaterialsSingle-Density Insole - Pre-molded and anatomically shaped comfortable EVA supports your feet, and a silicone top-print adds traction to the fleece-lined footbed. Gravity+ Outsole - This outsole comes with a full EVA bed for natural cushioning. We also added a soft rubber toe tip for extra grip. And if you look at the lugs, we got inspiration from the treads you see on snowcats. The result is maximum comfort and grip, and our lightest outsole.
