Your choice of ski boots depends on your type of skiing. As the essential interface with your skis, your boots must provide both comfort and foot support. Here is our advice for making the right choice. Every foot is different — to choose well and avoid regrets once on the slopes, it is important to consult a professional who will assess the morphology of your foot and point you towards the right model.
Choosing ski boots suited to your feet
Choosing a boot suited to your foot (e.g. men's or women's, size and width) is the first step towards finding the ideal ski boot. Furthermore, your needs will vary depending on your level and the terrain. You must therefore choose the right boots for your type of skiing.
It is important to measure your foot correctly — both in length and width. Volume is equally important: a narrow foot in a "wide" boot is very uncomfortable, the foot moves around and you lose precision. That is why it is important to consult a professional in-store.
How do you find your ski boot size?
If you want to find your size directly in Mondopoint (which corresponds to the length of your foot in centimetres), you can of course measure your foot yourself.
- Place an A3 sheet of paper on the floor against a wall
- Stand with your back flat against the wall and press your feet against it
- Draw a line in front of the toe that extends furthest on the sheet
- Measure and add 1 cm (maximum) to determine your ski boot size
It is also essential to take into account the metatarsal width, which corresponds to the widest part in mm across the forefoot (metatarsus). You can take the measurement by placing your foot on a ruler. Boot width is chosen according to the skier's needs:
- 92 mm: very narrow. Reserved for competitive skiers.
- 96–98 mm: narrow. For a slim foot or a skier seeking precision at the expense of comfort.
- 100 mm: average width, suited to most skiers.
- 102 mm: for a wide foot.
- 104 mm: for a very wide foot.
Flex
Your skiing level will determine the flex — that is, the stiffness of your boot. The higher the value, the stiffer the shell. As a general rule, a flex of 60 to 80 is recommended for beginner or intermediate skiers, offering greater mobility and flexibility, while 90–110 is aimed at advanced skiers. A flex of 120 and above is designed for expert skiers. If you are an occasional skier of average level, base your choice on comfort rather than precision and performance.
The inner liner
The inner liner is the primary comfort element of your ski boot. Independent from the shell, the liner is removable — meaning it can be taken out and replaced. It provides protection against cold and moisture while keeping your foot warm, allowing you to ski with dry feet. You will find on the market liners described as "heat-mouldable" or "memory foam". They are designed to perfectly match the shape of your foot.
Buckles
Another component of a ski boot: the buckles. They allow you to close and adjust the tightening of the shell. Depending on the ski boots you choose, they can be fitted with 3 to 4 buckles primarily. 3-buckle ski boots help reduce pressure points and offer cable tightening with better load distribution. Most ski boots feature 4 buckles, allowing more precise tightening.
It is important to note that each ski boot brand can have variations in sizing and flex, so it is always recommended to try several models to find the one that best suits your foot.
Our tips for keeping your ski boots in good condition
- Do not leave your ski boots outside overnight — the cold will destroy the insulating properties of the inner liner.
- Remove the inner liners from the shells when drying your boots.
- Do not place your ski boots near a heat source. Keep them at a safe distance, as the heat risks melting certain components of your ski boot.
- When storing your ski boots for an extended period, fasten the buckles. This will help them retain their original shape and therefore their performance.
- A boot bag to protect your boots when storing them — essential for protecting them from moisture.
Before making a purchase, don't forget:
- Your ski socks are also a key factor in foot comfort — bring them along when trying on boots.
- Bear in mind that the liner will compress slightly after a few sessions on snow.
- The foot must be held in place, but not compressed.
- The heel must not lift more than 0.5 cm.
- That your toes do not touch the shell.
- Tightening must be easy and precise.
