AsymWrap is our surfy yet responsive binding platform, designed for maximum board feel and tweakability. AuxTech: Hinged patterns for next level connected-comfort. A Rome first innovation, AuxTech is a game changing pattern we use in our ankle and toe straps. Auxetic Patterns are geometric patterns that become thicker perpendicularly when stretched. Essentially a network of tiny hinges that expand evenly when pressure is applied. Best in the game surface area pressure distribution and connected comfort, that’s AuxTech. UltraFlex Pro Ankle Strap: Powered by AuxTech, the UltraFlex Pro Ankle Straps feature an overmolded design and open 3D edge for our most powerful, reactive and locked-in feel. DuraCush: DuraCush SubBase Pad. An ultra-comfortable SubBase pad material, this unique E-TPU is hyper resistant to cold temps meaning you get the same impact absorption and smooth ride, no matter the temp. G Baseplate: 15% Glass. A mellow and medium flexing feel for a smooth ride. The Katana is a lightweight, hyper-responsive, game changer of a binding. Built on the surfy AsymWrap Platform and perfectly balanced with the locked-in hold of our UltraFlex Pro Ankle Straps, powered by AuxTech, the Katana truly makes any board ride better. A team rider and in-house favorite, the Katana is cult classic thanks to the next level adjustability of PivotMount and its freakishly lightweight design.
