BORN TO RACE, BUILT TO GROW WITH THEM. The K90R SC is Kästle's short-cuff junior race boot for skiers ready to push flex and precision on course. A 90-flex K-Blend shell delivers stiffness without sacrificing comfort, while K-Active Technology sends power straight to the edge. K-Tilt canting dials in stance, and GripWalk soles make the walk to the start gate as solid as the run down it.
