When Nedeckerbuilt the Sierra-W, theyset out to make the lightest snowboard boot they'veever made, without sacrificing the signature ride feel of the modern Nidecker boot line. The lighter your boot, the longer and harder you can ride. And they'restoked to say that the Sierra-W is 27% lighter than its predecessor. When you're dropping weight, it all starts at the outsole. With the Sierra-W, theygave it theGravity outsole, which is made out of lightweight and durable EVA. Theyshaped the lugs in the same way as the rest of theoutsoles - by taking cues from mountain playgrounds, then adapting them to give you as much grip as possible. The upper part of the boot is closed swiftly and with precision via a single H4 Boa dial on the tongue. We used Boa's TX3 textile laces to drop even more weight, add durability and give a more natural feel to the closure.
