The X Max 90 W delivers exactly what good intermediate and advanced skiers want: performance from a carefully tuned construction, paired with the comfort of a customised fit. 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. The impressive 360° Custom Shell is moulded in-store to each individual\'s feet for an even pressure distribution and excellent foothold, increasing in width by up to 6mm if required. The pre-shaped 3D liner provides an impressive initial fit, following the contours of the ankle, evening out pressure and increasing heel retention. extra customisation comes from the heat moulding of the liner done during the fitting to enhance comfort and produce the best possible shape.
