If you're buying ski boots, choosing the right size is important. Well-fitting ski boots ensure control over your skis. If you buy ski boots that are too big or too small, it will quickly lead to discomfort such as painful and cold feet.
When purchasing ski boots, we recommend having them fitted during a ‘bootfitting’ session. During a proper bootfitting, an analysis is made of your foot to determine which boot suits your foot best. The fit may also be optimized with custom insoles and by heating the liner (inner boot) and/or outer shell.
Would you like to buy your ski boots online? In this article, we explain how to measure your foot yourself to determine which ski boot size you need. We help you determine your ski boot size by measuring the length and width of your foot. You can then use this information to filter on the Snowcountry website and find a selection of ski boots that match your feet.
For ski boot sizes, we look at the length of your foot in millimeters. This measurement is expressed in Mondopoint (MP). To determine your Mondopoint size, you will need:
Besides your Mondopoint size, the width of your foot is also important. The width of your foot is called the last. Do you have narrow feet, wide feet, or something in between?
Use the step-by-step guide below to determine your Mondopoint and last. We recommend never using a conversion chart from your regular shoe size to determine these measurements.
Tip: Measure your feet at the end of the day. Over the course of the day, your feet slightly expand, as they do while skiing.
Place the paper on the ground with the short side against the wall.
Step onto the paper with your bare foot, heel against the wall. Stand up straight and make sure your heel lightly touches the wall. Ensure the paper is still properly aligned against the wall.
Draw a straight line at your big toe using the pencil. It is important to hold the pencil straight up. If possible, have someone else draw the line for you.
Also, draw straight lines on the outer sides of your foot at its widest part. The widest part is directly behind your toes at the ball of your foot.
Use the ruler to measure the length from the edge of the paper to the line at your big toe. This is the length of your foot in millimeters, which determines your Mondopoint size.
Measure the distance between the two lines on the sides of your foot. This is your last.
Write down both measurements.
Repeat the above steps for your other foot. When selecting your ski boots, always base your choice on your larger foot.
Use the Mondopoint size chart below to determine your Mondopoint size based on the length of your foot in millimeters.
| Foot Length (mm) | Mondopoint Size |
| 214 - 225 | 22 / 22.5 |
| 224 - 235 | 23 / 23.5 |
| 234 - 245 | 24 / 24.5 |
| 244 - 255 | 25 / 25.5 |
| 254 - 265 | 26 / 26.5 |
| 264 - 275 | 27 / 27.5 |
| 274 - 285 | 28 / 28.5 |
| 284 - 295 | 29 / 29.5 |
| 294 - 305 | 30 / 30.5 |
Example: If your foot length is 262 millimeters, your Mondopoint size is 26 / 26.5.
Now that you know your Mondopoint size and last, use the table below to determine your ‘boot volume.’
Note: Volume affects not just the width but also the overall space in the boot. A low-volume boot is not only narrower but also lower.
| Low volume | Mid volume | High volume | |
| 22 / 22.5 | 90 | 91 - 93 | ≥ 94 |
| 23 / 23.5 | ≤ 92 | 93 - 95 | ≥ 96 |
| 24 / 24.5 | ≤ 94 | 95 - 97 | ≥ 98 |
| 25 / 25.5 | ≤ 96 | 97 - 99 | ≥ 100 |
| 26 / 26.5 | ≤ 98 | 99 - 101 | ≥ 102 |
| 27 / 27.5 | ≤ 100 | 101 - 103 | ≥ 104 |
| 28 / 28.5 | ≤ 102 | 103 - 105 | ≥ 106 |
| 29 / 29.5 | ≤ 104 | 105 - 107 | ≥ 108 |
| 30 / 30.5 | ≤ 106 | 107 - 109 | ≥ 110 |
Example: suppose your Mondopoint size is 26 / 26.5 and your last is 99 millimeters, then your boot volume is “mid volume. The same is true if your last is 101 millimeters.
The further your foot's last deviates from average (mid volume), the more likely you will need a bootfitting to get the shoe to fit properly. In order for the ski boot to fit properly, it will probably be necessary to fit a custom sole and/or manipulate the ski boot by heating.
Example: if you have Mondopoint 26 / 26.5 and a last of 97 then you just fall into low volume. If your last is smaller, then it becomes increasingly likely that bootfitting is necessary.
Now that you know your Mondopoint size and boot volume, what’s next? Simply visit our ski boots page and filter by your Mondopoint size and boot volume.
To make it as easy as possible for you, we have created the table below. Click on the correct boot volume for your Mondopoint size, and you will open our ski boots page with the filter already set correctly.

| 25 / 25.5 | Low volume | Mid volume | High volume |
