How to Choose Alpine Ski Boots?

1. When should you change ski boots?

Visible Signs That You Need New Boots

The golden rule? Don’t wait for your ski boots to be uncomfortable. A first sign that you need to change your boots is that your liner no longer fits snuggly; this leaves room for your foot to move around, which can cause injuries. Another sign that you need new boots is a shell that has dried out, which means it could crack.

A Ski Boot’s Lifespan

Clearly, a skier who spends three hours on the mountain won’t wear out boots as quickly as one who spends eight hours a day multiple times a week there. In theory, you should get new boots every ten years—more specifically between 120 and 150 ski days.

2. How to measure your feet?

The first step is to measure your feet to analyze their shapes. How to measure your feet? There are two ways to do so.

Having Your Feet Measured in Our Store

We measure your feet using a tool that allows us to take a complete footprint. This enables getting an accurate measurement of each foot’s length, width and arch shape. It’s not uncommon for each foot’s characteristics to be different.

How to measure your feet at home?

1. Place a sheet of paper on the floor against a wall.
2. Place your foot on the sheet, and press your heel against the wall. 
3. Bend your knee slightly to reproduce the skiing position. 
4. To determine length, draw a line in front of the foot at the end of the big toe. 
5. To determine width, draw a line on both sides of your foot’s widest point—namely, the fifth metatarsal. 
6. Measure the length between the line and the tip of the sheet adjacent to the wall in centimetres. 
7. Measure the width of your foot between the two points in centimetres. 
8. Repeat the steps for your other foot. There are often differences between the two. 
9. The longest measurement determines your ski boot size.

3. How to size ski boots?

Once your foot has been measured, the length in centimetres will determine the size in Mondos, which is the unit of measurement used for ski boot sizes. You can also refer to a table, such as the one below.

4. How to choose a ski boot width?

The width in millimetres when measuring your feet corresponds to one of the three ski boot widths. These different widths fit narrow, medium and wide feet. The term last is often used to define this ski boot characteristic. 

Wide — 102 mm to 104 mm

Medium — 100 mm

Narrow — 96 cm to 98 mm

5. How to choose your boots’ flex index?

The terrain where you ski is a decisive factor in boot choice. There are different flex indexes for boots—soft, medium and stiff—aimed at different types of skiers.  

Softer boots are more forgiving and make turn initiation and release easier, while stiffer ones are more responsive and therefore have both more power and better control over the skis.

Flex Index for Kids’ Ski Boots

There aren’t really flex indexes for young children who wear 14 to 21 in Mondopoint. However, for older kids, boot flex varies from 60 to 90. The more a child grows and his or her level of skiing improves, the more the young skier will need a boot with a flex index in line with his or her progress and desire for performance.

6. How to adjust ski boots?

It may seem easy, but a well-adjusted boot makes all the difference. First, open the cuff and put on your boot. It doesn’t matter whether you start by attaching the top or bottom buckles.  

1. Go through once, and fasten all the buckles. 
2. Go over them again to check that they’re properly fastened. 
3. Don’t make them too tight. 
4. The bottom two buckles should be fastened without too much tension. 
5. The top two buckles can be closed with a bit more tension but without cutting off your circulation. A lack of circulation leads to cold feet.

7. When to use a boot fitting service?

Although the liner usually moulds quite well from the heat of your foot after a few outings, you may feel some pressure points or discomfort. This can even be the case when you’re trying them on in the store. That’s what boot fitting is for!

The shell and liner can be heat-moulded in our store so you can have an optimal experience on the mountain. Always keep in mind that a boot that’s too narrow can be enlarged, but material can’t be added to shrink a boot that’s too wide.
