How Do I Select the Right Ski Boot Flex?

Ski boot flex pertains to the resistance offered when leaning and pressing forward in an adequately fitting alpine boot with slightly bent knees.

The flex level indicates the boot's forward direction flexibility. Typically, the most commonly bought alpine ski boots come with flex ratings: Men ranging from 80-130, while for women, it's between 65-110.

Keep in mind, this chart serves as a guideline, and some skiers may not align with it due to unique preferences, skills or body weight. The recommended flex numbers span a range of 10-25 points.

If your goal is to advance your skiing skills with these boots, it's advisable to select a boot at the upper end or even beyond the suggested range. For beginners, opting for a lower number within or beneath the suggested range is recommended.

This chart doesn't account for the fact that flex ratings lack standardization and can differ among brands. Additionally, temperature variations can impact the ski boot flex experience.

Provided below is a guide table to aid in selecting the flex that best suits you.
