390 Boss FW Pro
The all-new 390 Boss FW Pro injects carbon into a cult classic for park rats, shop kids and all-mountain marauders alike. The perfect blend of the response of our FullWrap Platform and the locked-in playfulness found in our AuxTech® strap package, is the next generation of the 390 Boss.

Technology
FullWrap
Our bombproof platform, the FullWrap heelhoop chassis has four connection points to the baseplate for maximum energy transfer and pure connected-power. Built with more lateral support than the Asym platform, FullWrap bindings are designed for advanced stability, durability and power.
Kink Straps
New for this season, Kink Straps are designed to allow riders to choose from two different ankle strap positions on the boot. Ride it up for a more powerful feel, drop it low for a looser ride.
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.
ProGrip Toe Strap
Powered by AuxTech®, ProGrip Toe Straps provide next level, locked-in hold and grip.
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®.
G Highback
Highback Materials: 15% Glass 85% Nylon
C Baseplate
30% Carbon. A powerful and hyper response boost of carbon for hard-charging bindings.
Forged Aluminium
Forged Aluminum heelhoop for lightweight strength and durability.
2% Footbed Canting
2 Degree Dual-Density footbed
Never Miss A Day
We never want you to miss a day of riding. If you ride hard, there's always a chance something could wear out or break. But don't worry - we've got you covered. Bindings with the "Never Miss a Day" feature come with a backup parts kit, including extra ladders, screws, and washers, so you can keep riding while sorting out replacements.
