The Chase Boa® is a boot that offers a more responsive and professional level fit than our other Boa® fit systems. The Chase Boa® is equipped with the durability and grip for all-mountain adventure, while the fit is upgraded with the comfort and support provided by the Cloud 9 Liner and Armored Spine. 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. When working together 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 is upgraded to comfort level 1000% with the Air Dampening in the heel and Flex Link Design around the ankle for long-day carving groomers and pow.
