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.
