The Flex Booster, available as an add-on, enhances the stiffness of a boot’s tongue, giving it a firmer flex and added support. By revitalizing or boosting a boot's flex, it can even help extend the boot's lifespan. With its advanced design, the Flex Booster provides increased resistance as it flexes, maximizing support and protection, particularly against hard impacts. A bonus feature of this accessory is its adaptability: it allows you to adjust the boot's flex to suit different types of rides — whether you’re reinforcing a jib boot to tackle jumps or converting a freestyle boot into a banked slalom powerhouse. No gym shorts required to appreciate this boost in flex.
