What is the flex?

Boot width

• Medium
• Narrow
• Wide

A last width < or equal to 99 mm (MP 26./26.5) is ideal for skiers with narrow feet and those looking for a tighter fitting, more reactive boot. To identify one’s preferred last, the foot’s width between the first and the fifth metatarsal bone is measured to gather an overview of the skier’s natural foot shape and volume.
