How to Choose a Ski Boot Size

Ski boots are quite possibly the most important piece of gear to invest in. The right ski boot can elevate the ski experience, increase control, and even help a beginner skier level up quicker. This is why it is super important to get fitted for the right size and shape for your foot, here at Skiis and Biikes we offer bootfitting at all our locations.

How are Ski Boots sized?

Ski boots are sized using a measurement system called Mondopoint, it measures the length of your foot in centimeters giving the most accurate idea of your boot size. Ski boots only come in full size increments. The box will say half sizes: this is a carry over from when a thicker liner was the half size difference maker. A 27.0 boot and a 27.5 boot will usually use the exact same shell and liner and there is no difference in fit.

There are two general types of boot fits:

Comfort Ski Boot Fit refers to a roomier fit usually suitable for beginner to intermediate skiers. If you ski on groomed terrain and at slower to moderate speeds this might be the right fit for you.

Performance Ski Boot Fit is suitable for intermediate to advance skiers or those who ski frequently. This fit provides more control at higher speeds on mixed conditions from groomed to heavy powder.

When choosing a fit sometimes expert to elite skiers will choose a smaller fitting boot, the tighter the fit the more control you have over your skis.

Ski Boot Sizing Questions

Why you should invest in quality ski boots?

As a beginner, you want to set yourself up for success from day one. A good pair of ski boots will vastly improve your comfort level and give you more control as you send it down the mountain.

What are the most important factors to consider when shopping for ski boots?

Size The length and width of your foot in centimetres. Your boot fitter will measure your feet when you come into the store. This is the easiest and surest way to find your perfect size.

Fit Your ski boots should fit snugger than your everyday footwear. That being said, beginners can get away with a roomier boot. Your boot fitter will help you find the right balance between comfort and performance.

Flex The stiffness or flexibility of your skis will determine how much effort it takes to make your skis move. Not surprisingly, beginner’s ski boots have more flex.

Skiing Style Professional skiers often spring for tighter skis because they provide more control. But you can go for a somewhat roomier fit if you’re just starting out or only plan to ski for a handful of days. You’ll be way more comfortable and your feet will thank you.

Finding the right fit

Getting a boot fit at Skiis & Biikes is the first step. We’re not just saying that. There is no at-home alternative to a good ole boot fitting. That being said, there are some general rules of thumb you should know.

Mondo, Mondo, Mondo

Ski boots use the Mondo point sizing system. The Mondo system measures the length of your foot in centimetres.

Your boot fitter will measure your foot when you come into the store, so there’s no need to know your size off the top of your head.

Although many ski brands use half sizes, there is no difference between a full and half size. Weirdly, skis that are labelled 24.5 and 24 will have the same plastic shell size; however, the liner will be extra thick in a 24 to take up that half size. Make sense?

How should a ski boot fit?

Your ski boot should fit snugger than your regular shoes. There’s a good reason for this: having a roomy ski boot could lead to discomfort and even injury. When wearing your boot, you should feel your toes making light contact with the boot tip and a solid heel hold when you’re buckled up and flexing forward.

If your feet are on the wide side, you might want to choose a boot that is 100 mm or more in width. If you have narrower feet, a ski booth that is less than 100 mm would be the way to go.

What's the best ski boot for beginners?

One that fits your foot. The right length, the right width, shape and flex. A boot fitter will ask you a variety of questions to help you determine which combination makes sense for your feet, abilities and skiing style.

When will the feeling return to my toes?

We can’t say for sure. But we can tell you that one of the best feelings is pulling off your ski boots at the end of a long day on the hill.
