Technology
The 390 Boss FW is Rome's tried and true, team favourite binding. It's built on the bombproof FullWrap Platform: a forged aluminium heelhoop with four connection points to the baseplate for maximum energy transfer, response and stability. This is the Artifact colourway, matching the Artifact boards.
Flex 7/10, adjustability 7/10. Park-focused and all-mountain capable.
Construction
G Baseplate (15% glass) for a mellow, medium-flexing feel, a 100% nylon highback and a 2° dual-density canted footbed. The forged aluminium heelhoop gives lightweight strength and durability.
UltraFlex Pro ankle straps and ProGrip toe straps are powered by AuxTech®: auxetic patterns that get thicker perpendicularly when stretched, a network of tiny hinges that expand evenly under pressure for next-level connected comfort and locked-in hold. Kink Straps let you choose between two ankle strap positions on the boot. Never Miss A Day: comes with a backup parts kit with extra ladders, screws and washers.
