The most high-end all-mountain boot, designed for peak performance across diverse terrain. This season’s updates include a brand-new BOA AuxTech® PowerStrap combined with a unique double side-BOA® configuration that allows you to fine-tune the flex at shin level while keeping the boot snug around the midfoot. They added a new FlyKnit SnowGuard to keep snow from melting inside your boot. The new Acid also features an Injected Progressive FlexTongue with FutureProof flex properties. If that wasn’t enough, Bataleon also redesigned their Vibram® outsole and updated the CriticalFoam Midsole. This boot offers the most next-level riding experience.
