From Spark R&D The Surge is built for big days on big lines, and is preferred by our bigger, more aggressive riders. Solid baseplate design, stiffer Rip 'N' Flip highbacks, and more supportive Pillow Line ankle straps combine to give riders greater control in demanding terrain. All Surge bindings incorporate our industry-leading Tesla T1 technology. This season an optimized snap ramp will help shave a few extra grams. Every piece of this binding is made in-house with the exception of a few screws and the buckles!
