Spark R&D Arc ST Pro Splitboard Bindings 2025

The Spark R&D Arc ST Splitboard Bindings have improved dramatically over time, with their ST (Smooth Touring) overmolded design making the bindings super quiet and virtually friction free. Now the Spark R&D Arc ST Pro Splitboard Bindings up the ante with Pebax® (a plastic commonly used in AT ski boots) straps, ladders and adjusters, lighter but equally strong 7075 Aluminum heel loops, and re-designed hardware with Hex head and better anchoring at the heel loop.
