The Fenix features an asymmetrical baseplate with PowerBeams and comfy 2.5? canted EVA-footbeds. New this season is the light-weight ExoFrame Fusion PowerStrap for even better fit and power transfer. The 1-piece UniBack offers perfect anatomical support for your boots, and automatically triggers the Active Strap Technology. So, getting in and out of these slightly-wider bindings is absolutely effortless.
