Flex Booster

Flex Booster


Available as an accessory, the Flex Booster strengthens a boot’s tongue, creating a stiffer flex while offering additional support. It can also prolong the life of a boot by restoring or enhancing its flex. Thanks to a progressive design, it provides greater resistance as it bends, optimizing support and protection—especially from harsh landings. As icing on the cake, the Flex Booster enables you to modify a boot’s flex for specific adventures—be that reinforcing the flex of a jib boot to slay kickers or transforming a freestyle boot into a banked slalom hero. You don’t need gym shorts to appreciate this flex.
