Ski Boot Buying Guide

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.  

Width 

Each brand will offer different models with different width fittings, this is referred to as the Last. It is a measurement across the widest part of the boot, given in mm for a size 26/26.5 boot. Narrower, lower volume boots have a last width around 98mm, medium width/volume boots about 100mm and wider, higher volume boots 102mm+.  

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.
