The Surge ST Pro bindings are some of the lightest and highest performing splitboard bindings on the market, made with extreme attention to detail and premium materials and components. Every little thing on this binding has been engineered for perfection, even down to the screws which feature a hex head instead of phillips which are less likely to strip. Unthreaded heel loop shoulders improve connection and precision, and the Carbon Reinforced Nylon Highbacks maximize response without compromising on weight.

Key Features
  • CNC Machined
Carbon Reinforced Nylon Highbacks
  • Carbon reinforced highbacks are more responsive, lighter, and stiffer than Spark's standard glass reinforced highbacks. Injection molding allows for more complex geometry and improved impact strength compared to other methods of carbon fiber construction.
Pebax Plastics
  • Full Pebax plastics in Pillow Line straps, ladders, & adjusters -
  • Pebax is a premium material most often found in high-end ski boots as it provides consistent stiffness and improved toughness in cold temperatures. It’s also 20% lighter than Spark's standard material.
Hollow Pivot Pins
  • Made with stainless steel and hollowed out to be 33% lighter than standard pins.
7075 Aluminum Heel Loops
  • 7075 Aluminum heel loops are thinner and lighter than the standard heel loops while maintaining the required strength.
  • Medium: 1.36 lb/ea (620g) - 2.73 lb/pr (1240g)
Gram Counting
  • A 65% weight savings is found by replacing 7 stainless steel components with 7075 aluminum hardware, custom made in-house.
Pillow Line Straps
  • Pillow Line Straps are lightweight, durable, comfortable, waterproof, one-piece molded construction, and made 100% in-house. Arc ST ankle straps are smaller around the boot with a flex window for max agility while maintaining support. Toe straps are designed to be used as a toe cap, but also fit nicely as a traditional strap across the top of the boot.
ST Touring Brackets
  • NEW ST Touring Brackets incorporate the best features of aluminum and thermoplastics. Spark R&D overmold their custom plastic blend over and through the holes in the aluminum base, forming bushings that last four times longer than their previous brass version.
ST Whammy Bar
  • The ST Whammy Bar climbing wire is built right into the baseplate. Overmolded plastic where the bar contacts the baseplate allows for super-smooth climbing wire deployment and transitions.
Key Features

CNC Machined - CNC machined baseplates with maximum cutouts shave weight, yet maintain strength and performance. All of the baseplate side windows have been partially filled to increase durability and strength. Cutouts also conveniently allow for puck adjustment with bindings in place for precise stance placement.
