Frequently Asked Questions
What is mondo point in ski boots?
Mondo point (MP) is the universal ski boot sizing system based on foot length in centimeters. A mondo size of 27.5 means the boot is designed for a foot that is 27.5 cm long. It eliminates confusion from varying US/EU size scales across brands.
What flex should my ski boot be?
Beginners should use flex 60-80, intermediates 80-100, advanced skiers 100-120, and experts/racers 120-150. Heavier skiers should go stiffer, lighter skiers softer. Women's boots are typically rated 20 points lower than men's for equivalent stiffness.
How should a ski boot fit?
A properly fitting ski boot should feel snug but not painful. Your toes should lightly touch the front when standing upright but pull back slightly when you flex forward. There should be no heel lift. Performance fit means about 0.5 cm less than your actual foot length.
