can't really answer your question beyond what was already said. i believe they're an italian bike shoe company that started making boots about 20 years ago.
i bought new 09 northwave decades this year and have about 12 days on them. so far i'm loving them, super comfortable, responsive, supportive, and warm. they did pack out a bit more than i thought they would, but no biggie. i tried on the 2010s and loved 'em, but noticed they're the same as the 2009 just a different design. picked up the 2009s on brociety for 75 bucks. best deal i've gotten on any snowboarding equipment hands down.
