What Ski Boot Flex Should I Choose?

The boot flex indicates the amount of resistance the boot offers when leaning and pressing forward in a properly fitting alpine boot with slightly bent knees.

Essentially, flex refers to the boot's flexibility in the forward direction. Generally, the most commonly sold alpine ski boots feature the following flex ranges: Men between 80-130 and women between 65-110.

Keep in mind that this chart serves as a guideline. Some skiers may not fit within these parameters due to specific preferences, skills, or weight. The suggested flex numbers typically range within 10-25 increments.

If you aim to advance with these boots, select a boot in the higher end of the range or even above the recommended values. Beginners should opt for a lower number within the range or even below the suggested flex.

Note that this chart does not account for the fact that flex ratings are not standardized and can vary between brands. Additionally, temperature changes can influence the ski boot flex experience.

Below is a guide table to help you choose the right flex that suits you best.
