About the product

The Arc ST is designed for the splitboarder who wants a lightweight feel, easy handling and full control on the descent. The construction is based on Spark's ST technology that provides smoother transitions, reduces friction and makes everything more intuitive - from changing positions to standing stable in traverses.

The baseplate is cut to minimize weight without compromising strength. This makes the Arc ST flexible and responsive, perfect for those who like playful riding with natural flex. The highback features Spark's Rip 'N' Flip system that allows you to adjust the position for uphill and downhill without tools. The straps in Pillow Line material provide a direct and clean feel to the boot with low weight and high durability.

Technical details

  • ST Touring Brackets – updated touring mechanics with less friction at transitions.

  • CNC-milled base plate with cut-out sections for low weight and good energy transfer.

  • Asym Rip 'N' Flip Highback – two positions for walking/riding and easy forward lean adjustment without tools.

  • Pillow Line Straps – lightweight construction with high dimensional stability and good pressure distribution.

  • Whammy Bar – touring wire that makes it easy to switch between different climbing angles.

  • Tesla T1 system – fast and reliable transition system between touring and ride mode.

  • Medium flex – flexible and playful feel, but still stable on steeper terrain.
