Frequently Asked Questions
Everything you need to know about using this application.
What is Mondopoint sizing?
Mondopoint is a standardized sizing system used primarily in ski and snowboard boots. It represents the length of the foot in centimeters, making it a precise metric for boot fitting that avoids the inconsistencies found in regional US, UK, or EU sizing standards. By measuring your foot in centimeters, you can find your exact Mondopoint size, ensuring a proper fit that optimizes performance and comfort on the mountain. This universal measurement system helps eliminate confusion when switching between different boot brands.
How do I measure my feet for ski boots?
To measure your feet accurately, place a piece of paper against a wall on a hard floor. Stand on the paper with your heel against the wall, then mark the longest point of your toes. Measure the distance from the wall to your mark in centimeters to get your Mondopoint size. It is best to wear the same socks you plan to use for skiing or snowboarding while taking this measurement. Always measure both feet, as most people have one foot slightly larger than the other, and you should always size your boots based on the larger foot.
Why is my Mondopoint size different from my street shoe size?
Ski and snowboard boots are designed for a much tighter, more performance-oriented fit than casual footwear. While your street shoes allow for extra toe room for walking, ski boots must firmly hold the foot in place to transfer energy efficiently to the board or skis. Consequently, your ski boot Mondopoint size is typically smaller than your standard sneaker size. Relying on your street shoe size often leads to boots that are too large, resulting in foot pain and poor control while riding.
Can I use this tool for both ski and snowboard boots?
Yes, this converter works for both ski and snowboard boots. Both industries utilize the Mondopoint system to categorize boot sizes, as it provides a reliable, objective measurement that transcends regional sizing differences common in the footwear industry. Whether you are buying downhill ski boots or freestyle snowboard boots, the conversion method remains identical. Using our calculator ensures you are starting your fitting process with the correct base length, allowing you to fine-tune other factors like boot flex and width.
