Ski boot customisation

A correctly fitted boot should hold the foot securely without creating pressure points. While last width is a useful starting point, factors such as instep height, heel shape, ankle volume, and calf shape also influence fit. Many modern ski boots can be customised through heat moulding, shell modification, and liner adjustment to achieve a more precise fit.

Ski boot types explained

Alpine boots are designed for skiers who mainly use lift-accessed terrain. They typically offer greater downhill support and may be slightly heavier.

Backcountry boots are intended for skiers who access terrain beyond the lift network. All feature a hike mode to improve mobility when walking or skinning uphill, and they are often lighter than alpine models. They also typically use different sole standards to improve grip and compatibility with touring bindings.

Within the backcountry category, hybrid boots bridge the gap between alpine and tour-specific models. They feature hike modes but are more focused on downhill performance, making them a versatile option for skiers who split their time between resort and backcountry terrain.

How to find your ski boot size

It is important to select a boot that matches both your foot length and width. 

Length 

Ski boot lengths are determined in Mondopoint, which is measured in centimetres and corresponds to the longest part of your foot. Unlike normal shoes, ski boots need to fit your foot exactly. Getting the right-sized ski boots is important for progression and comfort. We recommend getting measured and fitted in-store to get the best boot for you.

Volume

Each brand offers different models with varying volumes. Selecting the correct boot volume is important and depends on the shape of your foot, how your foot tolerates compression, and whether you prioritise comfort or precision.

In-store ski boot fittings 

All our fitters are SUREfit trained and use the same clear, 5-step process. Here’s what to expect when you come for a boot fitting.


1. Assessment   

We want to know about previous experiences with ski boots, both good and bad, and to get an overview of skiing experience and aspirations. This is done alongside an assessment of the size, shape and biomechanics of the foot and lower leg. Using various techniques and equipment, we’ll find out anything that affects how a boot fits and make a recommendation for the best options, including the correct footbed solution.


2. Shell Check   

Ski boots comprise two basic components. A softer inner boot, for comfort and control; and a harder shell, for transmission, performance and fit. The shell governs how a boot fits, so a shell check is needed with every boot. The foot is placed into just the shell (no inner boot inside) and the amount of space is assessed in five crucial areas: length, ankle width, forefoot width, instep height and calf. This ensures the correct size, shape and volume. The shell check will clearly indicate the most suitable models.


3. Trying On   

The next step is to try on the complete boot. Brand new ski boots feel tight and short at first, which is normal. The inner boot is designed to fit in length and volume, initially with no excess space. It’s the customisation and with use, that he foams form to the shape of the foot. Doing up the boots correctly, leg clips first, brings the heel back into position and gives the toes more room. The boot is left on for 10-15 minutes in a standing position, mimicking a relaxed ski stance. It shouldn’t be necessary to try on more than two or three models. At this point it is crucial to remember that as the foam of the liner packs down, the ski boot’s internal volume can increase by about 15%, so a snug fit at the beginning is very important. 


4. Stabilising   

For boots to perform and be comfortable, it is important that your feet are stable while skiing. Boot-fitting problems generally stem from the foot itself, not the boot. Footbeds eliminate a lot of problems, dramatically improving the fit and skiing performance by supporting the foot structure. This helps muscles relax and stops them tiring so quickly, meaning there’s less movement and rubbing caused by collapsing of the foot. We cannot emphasize enough the importance of well-made custom footbeds to successful ski boot fitting.


5. Customisation   

Standard ski boots should fit well out of the box, but it is very simple to improve on this as they are designed to be adapted. For many models this is a part of the fitting process and, in most cases, will involve the inner being heated and custom moulded to the foot. With certain models the plastic shell can also be custom moulded. As specialists in boot fitting, we are also able to make bespoke changes to boots. This can take many forms, including modifications to the shell or liner via heating and mechanically stretching materials, carefully shaving plastics and foams, or altering angles and stance. The result is increased comfort and better performance.  

Our top tips for buying ski boots

Allow Plenty of Time    Image

Allow Plenty of Time  

Don't rush yourself, the initial fitting will take between 1 and 2 hours.

Know your feet

Consider and discuss your ski boot history and any previous problems you may have had with ski boots or your feet in general. 

Have an idea of budget Image

Have an idea of budget

Do some research and have a budget in mind for what you'd like to spend, though do be flexible if it means getting the most suitable model. Make sure the budget includes supportive footbeds if you don't already own them – they will improve the comfort and performance. 

Get measured by a professional Image

Get measured by a professional

Measuring is just a guide. The correct size will be gauged from a shell check with your foot in the plastic shell of the boot, without the inner liner inserted. This will confirm if the size, shape, and volume of the selected model are the correct match to your feet. 

Wear thin socks Image

Wear thin socks

New ski boots have warm padded liners that will support your feet and insulate them. Thick socks will only make the boot tighter, restricting blood flow and ultimately making it colder. Thin socks will improve precision, control and comfort. 

Choose the right boot Image

Choose the right boot

It isn't about how the boot looks. It's about the fit and function. Fit – the right size, shape and volume matter much more than colour, style or the latest trend. Focus on how they feel. Function – biomechanics and weight are just as important as ability. Some people need stiffer boots than their ability might suggest. The boot should support and work with you.

Select footbeds & stability

To make boots perform and be comfortable, you have to ensure your feet are stable when inside. A well-made custom footbed is the key to a successful boot fitting.

Wear around the house

After buying your new boots, wear them as much as possible either skiing at indoor snow centres or dry slopes, or at home whilst standing up. The more you wear them, the more the liner will soften and mould to your feet.

Modifications

There are only a small number of brands and styles of boots, but there are millions of different feet. Ski boots are designed to be modified to accommodate lumps and bumps. Our staff have the tools and knowledge to stretch and grind plastic shells, transform inner boots, and alter angles and flex.

After sales service

Sensations like minor tingling, slight numbness or some hot spots can be expected to start, as the liner packs down. If they don't ease with use, take the boots in store for modification. Even if you have a more painful problem in most cases it only takes a small adjustment to fix it. We provide free customisation work on all our boots. 

Next Steps

Book a ski boot fitting appointment in-store. The right fit will keep you skiing longer, safer, and with more control.
