Multiple flex points are designed into the lower frame by designing the shell thickness. The shell is designed to move like a joint, using the flex points as fulcrums. The shell automatically widens to accommodate wide foot widths, and the buckle can be tightened while maintaining the shape of the instep. In this way, the foot width is automatically adjusted to fit the skier's foot. The multi-flex point also allows for smooth roll-in, even on stiff models with high flex values.

Last design for SLIM type R-EVO. Although the adaptation range varies depending on shell hardness, it accommodates narrow to standard foot widths. It provides a highly integrated feeling between foot and boot and sharp ski control to meet the needs of athletes and expert skiers who demand faster and more precise skiing.
Please note that the shell stiffness has been strengthened by increasing the wall thickness at the shell rise, which narrows the adaptation to the wide direction by 1mm.
