What is a Flex Rating?

The flex rating is associated with how stiff the boot is in forwarding flex, and your ski boot sizing is based on it. The higher the flex rating, the stiffer the flex. When pressure will be applied on the front of the boots to bend the ankles, the boot will be more rigid and reactive. Less flex means it will be easier to bend at the ankle with the boot. However, the boot will be less reactive.

Beginners are first-timers learning basic skills, whereas an intermediate skier is someone with control over their skis. According to the accurate ski boot sizing, athletic or heavy beginners can use boots designed for intermediate skiers.
