The X Max 90 W delivers exactly what good intermediate and advanced skiers want: performance from a carefully tuned construction, paired with the comfort  to let you ski all day long. Twinframe2 construction ensures there is rigidity in key zones like the spine and lower parts of the boot for maximum control and power, while softer plastics wrap over and around the foot for better comfort and hold. Oversized Pivots provide precise energy transmission and help drive skis cleanly.
