Built to fit any size foot the ARTP offers the perfect blend of comfort support and performance. Features: Independent Floating Tongue Feather Frame 2.0 Chassis Contoured Footbed TECHNOLOGY Feather Frame 2.0 Chassis The Feather Frame Chassis is the gold standard of comfort and function. Our one-of-kind framework stands on a pedestal as the only boot system to completely integrate the mounting system baseplate and outer shell seamlessly. This allows you to stand closer to the ski and offers a better connection to the water resulting in greater performance. New for this year the Feather Frame Chassis is modular to allow front and rear boots to be interchangeable. We have also manipulated the hole pattern in our rear boots to be compatible with every ski on the market. Every ski just got an upgrade!
