How do ski boot flex ratings affect skiing performance?

Ski boot flex ratings measure how much the boot bends forward, with stiffer boots (higher numbers) providing more control and power transfer for advanced skiers, while softer boots (lower numbers) are more comfortable and forgiving for beginners. The right flex rating helps match a skier's ability level, weight, and skiing style for better performance.

What Flex Rating Means

Flex rating is a number that describes how much force is needed to bend a ski boot forward from the ankle. It's like measuring how stiff or flexible the boot material is. A boot with a rating of 80 flexes more easily than one with a rating of 130. The number helps skiers choose boots that match their strength, weight, and skill level.
