If you are looking for the best fitting BOA® Fit System boot with an all-mountain flex, then you have come to the right spot because that is precisely what the Chase BOA® is designed to offer. Setting the bar higher with every stitch and feature is our focus on the Chase. When working with BOA®, we spent a lot of time making sure the BOA® fit system and the Nitro boot fit would complement each other to provide a fit and support never experienced before. The combination of the Dual BOA®, Fit System, Relace Liner Locker, and the Cloud 9 Liner make this the surest fitting and comfortable snowboard boot on the mountain. The durability and riding comfort is supported by the Vibram® Outsole made of Vibram® ECOSTEP™ Compound, Armored Spine. Additionally, the riding comfort has been upgraded to level 1000 with the Air Dampening in the heel and Flex Link Design around the ankle for long-day carving groomers and pow. So, if you are looking for the ultimate BOA® experience, then slip on and dial up a pair of the new Nitro Chase BOA ® snowboard boots.
