Product Details


Spark took the ready-to-rage Surge ST binding and went over every component with a fine-toothed comb looking for ways to improve performance and drop weight. The product of that effort is the new Spark R&D Surge ST Pro Splitboard Bindings, and they're a thing of beauty. When you can't afford to give up performance going uphill OR downhill, and you're going deep enough for every gram to count, the Surge ST Pro is the way to go.

Tour Mode

Improved ST (Smooth Touring) ModeSpark injection molds a proprietary thermoplastic over existing aluminum or steel parts in a process called "overmolding," reducing friction and improving durabillity.

ST Whammy BarsOvermolded plastic blend where the climbing wire meets the baseplate to eliminate stickiness. (Note: not backward compatible with previous Arc, Surge or other older models)

ST Touring BracketsOvermolded with low-friction proprietary plastic over and through the bracket holes in the aluminum base - strong, smoother pivoting, and lasts 4 times longer than the old brass bushing.

Hollow Pivot PinsMade with stainless steel and hollowed out to be 33% lighter than standard pins


CNC Machined BaseplatesCNC machined baseplates remain solid for max stiffness and durability. All of the baseplate side windows have been partially filled to increase durability and strength

7075 Aluminum Heel Loops7075 Aluminum heel loops are thinner and lighter than our standard heel loops while maintaining the required strength.


Pebax® Pillow Line Straps, Ladders and AdjustersPebax® is a plastic commonly used in high-end alpine touring ski boots, It is stiff, tough and 20% lighter than the standard material used.


Proven Burton Buckles
