Stiffness

• Hard
• Medium
• Soft

A flex rating between 100 and 130 for women, and 110 and 140 for men, ideal for advanced-level skiers and those whose morphology requires more sturdy support.
What is the flex?

Boot width

• Medium
• Narrow
• Wide

A last width between 100 mm and 101 mm (MP 26./26.5), considered average, offers greater volume and a more relaxed fit ideal for most skiers. 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.
