"What Our Gearhead® Experts Are Saying: ""I’ve toured countless days on the Arc ST and love how light and smooth they feel. The highbacks give me enough support without feeling restrictive, and the ST tech makes transitions super fluid. They’re playful, responsive, and perfect for tree runs or pow days."" We trust the Spark R&D Arc ST Splitboard Bindings when every ounce matters on the skintrack but we don’t want to sacrifice performance for the ride down. The medium-flex Asym Rip ‘N’ Flip highbacks and cutout baseplate design keep weight low and response snappy, while the surfy feel makes these bindings a natural choice for floating through deep powder or weaving through tight trees. Touring feels smoother than ever thanks to Spark’s Smooth Touring (ST) tech. Overmolded thermoplastic in the ST Brackets and ST Whammy Bars reduces friction and increases durability, so climbing transitions are effortless and reliable even after countless laps. Combined with tool-free forward lean adjustability, ergonomic left and right highbacks, and durable Pillow Line straps, the Arc ST is a versatile binding ready for long approaches and playful descents."
