The 2020 Peak 4D is a refined update to our top-performing binding. With feedback from Nico Lerchenfeld, we made one of best bindings even better. The 2020 Peak 4D is more responsive, with a firmer more dynamic flex. The all-new Reflex Walk-Out liner is more supportive and has a custom-fit feeling. You can ride all day in comfort and style! The Peak 4D is the ultimate park boot and great for boat riders as well.
