Why Do I Need The Best Ski Boots For Flat Feet
Anyone that has flat feet needs to take extra care when choosing ski boots. If you choose the wrong option, you could cause yourself unnecessary pain that will ultimately detract from your skiing experience.
Skiers with flat feet should be looking for boots that can provide additional support. Deep heel cups and structured support are crucial to stabilizing your foot inside the boot.
Many ski boot brands use a high-arch design with minimal support that is unsuitable for flat feet. If you choose one of these products, you could be in for a painful experience.
Finding a product that perfectly matches your foot shape and technical ability can be challenging. However, the options we have listed are more than capable of providing stability for flat footed skiers of all skill levels.
How To Choose The Best Ski Boots For Flat Feet
The term ‘last’ refers to the forefoot width of a ski boot. It is generally measured in millimeters, with most boots ranging from 96-104 in width.
As a general rule; skiers with flat feet require a wide last. With the sole and arch of your foot being firmly planted against the ground; overall foot shape often gets pushed wider than average.
It’s worth noting that narrow ski boots are one of the leading causes of foot pain. The crushing sensation that can occur is a recipe for discomfort on the slopes and usually requires urgent attention from a boot fitter.
Finding a boot with a medium-wide last will provide plenty of space to accommodate the added width. Most flat footed skiers will be looking at boots upwards of 100mm; depending on their own personal anatomy.
Shape & Volume
Finding a ski boot that naturally accommodates flat feet is vital. Certain boots come with a wider forefoot shape, deeper heel cup and flatter arch; all of which are vital to comfort.
In general; the anatomy and fit of a boot will vary between brands. In our experience; we have found Nordica, Rossignol, Salomon and Technica are some of the most accommodating for flat feet. However, certain models from alternate brands might also meet your needs.
It’s worth noting that boots with a ‘high-volume’ fit provide the most space throughout the boot. Although this is often the comfort choice, it can decrease foot stability and control.
The key for flat footed skiers is to find a boot that has ample forefoot space, but still has a snug fit around the heel and ankle. Although this can be a difficult balance to find, we believe that the boots listed here have the attributes required.
Footbed & Insole
It’s safe to say that footbeds can have a big impact on comfort and performance. Despite being only a thin layer of foam, it can often dictate the overall comfort of your boots.
Most ski boots come with a stock insole that is thin and flat. Although it will allow plenty of space to accommodate your feet, it can often leave you feeling unsupported.
Getting an aftermarket insole is usually crucial for skiers with flat feet. It can vastly improve the stability and comfort of your ski boots. It can be a ‘game changer’ for many.
If you’re interested in further customizing your fit; we suggest you read our guide to the best ski boot insoles and footbeds. It provides a great analysis of what you should look for and gives you a list of our recommended products.
Flex (Ability Level)
The amount of ‘flex’ a ski boot has is a key performance indicator. It refers to how much the boot flexes under pressure and is given a numeric value.
Ski boot flex ratings generally range from 60-130+. The fit feel and performance of your boot is reliant on its flexibility, so choosing the right option is vital.
- Soft flexing ski boots are best suited to beginners or lightweight skiers. They are the most comfortable and forgiving option, but also offer the least control.
- Medium flexing ski boots are designed for intermediate skiers. They offer a great blend of comfort and performance. However, they can lack the stability required by ‘hard charging’ or heavyweight skiers.
- Stiff flexing ski boots are designed for advanced, expert or heavyweight skiers. They provide supreme precision, control and support at high speeds. However, they are usually the most uncomfortable and unforgiving choice.
It’s key to choose a ski boot that matches your skill level if you want to maximize your performance. In order to guide you in the right direction; we have included the below table that correlates flex with ability:
Beginner - Intermediate
Intermediate - Advanced
Advanced - Expert
Expert - Race
Ski boot sizing is a paramount consideration for any skier. If your boot is too big; you will sacrifice performance. It it’s too small; you will most likely have a painful experience.
The correct fit should be ‘snug’ but not painful. You should feel like the tip of your longest toe is gently resting against the end of the boot. You should still be able to wiggle your toes.
When you push forward with your shin, your heel should remain planted to the floor. The overall feel will be tight and secure, but without any pressure points.
Keep in mind that a tighter fit can improve performance, but it usually comes at a cost to comfort. Experienced skiers should be looking for a compact ‘performance’ fit, while beginners are best going for a slightly more relaxed ‘comfort’ fit.
Ski boot sizes are measured using the ‘mondopoint’ system. It’s a measurement of your foot length in centimeters and provides greater accuracy than shoe size.
You can easily measure your mondopoint size by standing with your heels against a wall, then measuring the distance from the wall to the tip of your longest toe.
However, if you’re looking for a quick solution, it’s also possible to correlate mondopoint with shoe size. In order to make your life easier, we have included the below table:

Finding a comfortable pair of ski boots is essential if you’re still learning the basics. Upon review, we found the Salomon QST Access 70 provided an ideal base for flat footed skiers to perfect their turns thanks to its great fit and forgiving performance.
The boots come with an accommodating 104mm last and flat sole that is well suited to flat feet. The overall shape of the boot can be described as medium/high volume, providing a secure enough fit around the calves and ankles for reliable performance.
The 70 flex rating is forgiving enough to recover from the occasional mistake, although does tend to limit control at higher speeds speeds. It’s clear that the main focus of the boots has been warmth and comfort, which is true on and off the slopes thanks to a useful ‘hike mode’ setting.

The downhill feel of the boots is a blend of comfort and performance. Those looking to spend most of their time on groomed intermediate slopes will find the power more than sufficient, although heavier skiers might find them a bit soft on steeper terrain.
