More comfortable than ever before, the Aura™ Pro boots are all-mountain boots with a medium flex. They're a bit stiffer than the OG version to suit the needs of more experienced, aggressive riders. The V2 POPCUSH footbed works with the V2 UltraCush liner to provide both supportive structure and impact-absorbing comfort. With less fatigue, you'll be staying out until that last liftie kicks you off the mountain.
