The Sierra is Nidecker's lightest boot and a soft, forgiving choice for riders building confidence and linking their first real turns. One BOA dial on the tongue pulls a steel lace across the whole shell, so getting in and dialed takes seconds, even with cold hands in the Ski Bowl lot. A heat-moldable Bronze liner with an integrated lace lock, a Custom Flex Zone at the toes and a fleece-lined footbed keep it comfortable through full days of progression.
