The Salomon QST Pro 90 is a freeride boot built to fit comfortably, ski well, and walk easily, so you don't have to sacrifice anything. Endofit design offers close-to-the-foot feel, and the My Custom Fit 3D liner and Custom Shell 360deg ensure a tailored fit. Motion Flex with a Surelock mechanism make walking a breeze, but lock for reliable downhill performance as well.
