The Arc ST delivers lightweight efficiency and confidence in both tour and ride mode. Medium-flex straps and highbacks let it excel in the trees and powder, while staying tough enough for complex conditions and long expeditions. Built on Spark’s Tesla T1 system for fast, tool-free transitions.

Features


  • Tesla T1 baseplates — CNC-machined with maximum cutouts to shave weight while keeping strength; cutouts allow puck adjustment with the binding in place.
  • Asym Rip ‘N’ Flip highbacks — moderate glass-fiber fill for medium flex and a surfy feel; individual left/right highbacks with a flattened top for lateral mobility.
  • Pillow Line straps — lightweight, waterproof, one-piece molded; the ankle strap sits smaller around the boot with a flex window for agility and support.
  • ST Whammy Bar climbing wire — built into the baseplate with overmolded contact points for smooth deployment and transitions.
  • ST Touring Brackets — overmolded plastic-over-metal for durable, smooth tour mode.
