You don't know what size to choose for your ski boots and you have no clue about how to choose their width either.

It is very important to get the right size when it comes to ski boots. If your sneakers are too big, you're still gonna be fine. If your ski boots are not sized properly, it will ruin your day. Get them too big and your feet will move, creating friction and discomfort. Get them too small and your toes will get crushed, your blood won't flow as it should and you're going to feel cold. Trust us, you don't want any of this.

In this tutorial, Martin, our ski and touring ski expert, explains you how to size your ski boots precisely.

What Is Mondopoint Sizing and Why Is It Used Instead of Traditional Shoe Sizes?

The Mondopoint size, often abbreviated as ‘Mondo’, is an international measurement system primarily used for ski boots. It represents the foot length in centimetres. For example, a Mondo size of 27.5 corresponds to a foot measuring 27.5 cm in length. This measurement method offers greater precision and global consistency compared to traditional sizing systems, which vary by country (such as US, UK, or EU sizes). By using Mondo sizing, skiers and ski boot manufacturers can ensure a better fit, leading to improved performance and greater comfort, regardless of regional size variations.

What Size Should You Choose in CM for Your Ski Boots?

How to Determine Your Mondopoint Size?

To eliminate the uncertainty of UK, US, and EU size conversions, ski boots use the Mondopoint system, which corresponds directly to foot length in centimetres.

At Glisshop, we provide a foot measuring tool to accurately measure the length and width of your foot. Available in-store, we also offer a downloadable PDF version online.

To use the PDF foot measuring tool, first ensure that the scale is correct once printed—1 cm on the paper should equal 1 cm on a standard ruler. Then, place it against a wall and position your stronger foot on it. Mark a line at the tip of your longest toe and another at the widest part of your foot. For greater accuracy, ask for assistance in taking and reading the measurements.

To find your ski boot size, simply check where your front foot marking aligns with the Mondopoint (MP) scale. Determining foot width requires a slightly different approach—look for the intersection between your width marking and the pre-printed size chart on the measuring tool. This intersection will indicate whether you have a narrow, medium, or wide foot. Feel free to watch our video multiple times to fully understand the process.

Now that you know your Mondopoint size, you can confidently determine the right ski boot size and width for your feet.

What Is Ski Boot or Last Volume?

Ski boot volume refers to the internal space of a ski boot, including its width, height, and depth, to accommodate the foot. It is a crucial factor in determining comfort, as two boots of the same size can have different last profiles.

How to choose ski boot length?

The length of your ski boot must match your skiing level:

We can highlight two kinds of skiers:

Expert skiers tend to prefer precision to comfort. They will choose a boot size that matches exactly the length measured on the size guide. Example: an expert skier with a 27cm-long foot will pick a size Mondo Point 27.

Recreational skiers often favour comfort to performance. They can get an extra 1/2 size. Example: a recreational skier with a 27cm-long foot will pick a size Mondo Point 27.5.

How to choose ski boot widths?

Your boot width or boot last must fit your shapes.

In general, manufacturers release series of boots featuring different lasts. Some boots will target narrow feet while other models will best suit wide feet. Every skier can find the right boot for his feet.

Boot last or fit equals the width at metatarsals (the widest point). A boot width is always given for a size 26.5 which is considered standard. This helps you compare with other boots to find the right width for you.

For the record, if you want to go into details, a boot with a 100mm last will be 100mm wide only in 26.5. If you pick a bigger or a smaller size, you'll get a bigger or a smaller last.

Thanks to Glishsop size guide, you know your foot width. More specifically, you know if your foot is narrow, medium or wide.

If you have narrow feet, we recommend lasts ranging from 97mm up to 100mm.

If your feet have a medium width, you want a boot width between 100mm and 102mm.

If your feet are wide, prefer boot lasts over 102mm, this will keep your feet snug and happy.

Of course, these figures are only indicative. If you like charging hard and fast down the steepest slopes the resort can offer, you can pick a tighter fit to gain precision and performance. If you love cruising at low to moderate speed, if you want top-notch comfort more than anything else, then a wider last may be a better choice for you. Everything is a matter of feel, you need to feel good in your boots. If this means you need to pick a longer size than your feet or a wider last than the one recommended, do so. You'll be the one using them!
