Skiing with poorly fitting boots is like riding a bike without a seat. You’ll probably get to your destination, but it’s not an enjoyable experience.
In 2003 I built my Colnago Dream Plus road bike. I found Chris King headsets from a velo swap, the frame from an Ebay seller in the UK, Reynolds Ouzo Carbon forks, Campagnolo drive train, and Vittoria Open Corsa CX tires on Mavic rims. The bicycle is a work of ridable art. I still feel joy every time I take it on the road. Of all that went in to it, the most important selections I made were for the saddle, handlebars, and cycling shoes with Surefoot insoles – the points where my body touches the equipment.
Boots – There Are So Many Choices
I have skied in boots from several different makers – Raichle, Salomon, Rossignol, Tecnica, Atomic, Nordica, and Lange – and I gained insight to how my boots affect my body position and my technique. For instance, the boot’s ramp angle could be causing my heel to be too high or my toes to be too high, or the boot cuff could lean too far forward or be too upright.
Body position, ankle flex, and a neutral stance
Here is an exercise you can do at home with your existing boots, or in the boot shop when trying them on, or on the snow with your skis on. It’s one of several exercises I use to assess how the skier and their equipment are working together.
Boots with too much forward lean will put you ahead of the centerline, and boots that are too upright will sit your hips behind centerline. If you already have boots you like that don’t put you in proper alignment, adjustments can possibly be made by the boot fitter using toe or heel lifts, boot sole grinds, or cuff adjustments, but it is best to buy boots that align properly for your body.
Buying the Right Boots
My students and friends often ask how to select which boots to buy and I’m happy to give guidance when it comes to such an important decision. I recommend narrowing your choices to a few different boots, based on a few questions:
What is your height and weight, skill level, fitness level, and type of ski?
What type of terrain do you like to ski and what type of snow do you encounter most?
Different people with the same dimensions may have different requirements of the boot.
The Shell and the Liner
If you are able, find a professional boot fitter (I trust Surefoot) and with their help, try on your different options and follow these steps. You might find this approach unconventional but it will get you the best fit. Try on three sizes: Your usual size, one boot-shell-size smaller and one boot-shell-size larger (e.g., Sizes 25, 24, 26). In each size, check for which one fits your midfoot the best. Choose this size and work from there.
Next, is to take a “shell-fit” measurement by placing your foot in the shell of the boot with the liner removed and check for spacing between your foot and the shell for the length, and ankle placement. This will confirm that the make and model is a good fit for your anatomy. Lastly, check the forefoot width to make certain that it is not too tight or too loose in the toebox. Common widths in men’s boots are 97mm, 100mm, or 102mm. Your boot fitter can then adjust the width and length by punching and grinding the shell. In addition, injectable or heat moldable liners will help fill the inconsistencies between your foot and the shell of the boot. A stock boot liner with a solid midfoot fit may be all you need, however, I have a custom foam liner made to ensure my foot has the best possible fit, my ankle flexes properly, and my achilles and heel feel supported.
Orthotics and Insoles
A good insole or orthotic fills the gaps, gives your foot support, and places your ankle in a neutral position. This allows your leg to stack efficiently so that it is moving in alignment with the boot and ski. Proper alignment at the bottom* will allow the rest of your body to have the most versatility, range of motion, and will reduce fatigue. (*This is one of the meanings behind the name of the book: Skiing: from the Bottom Up.) When your foot is out of alignment, you are forced to make adjustments - in your ankles, knees, hips and spine - which are inefficient and sometimes lead to injury or pain. When your body is properly aligned and stacked and you ask it to move a certain way, it will; you won’t have to be making conscious adjustments to compensate for your misalignment.
Novice and intermediate skiers should have a softer flexing boot. A newer skier makes extraneous movements to stay in balance. If the boot is flexible it allows the energy to be absorbed rather than being fully transmitted to the ski and snow. As the skier becomes more skilled, the movements become more accurate and purposeful. A stiffer boot then transmits these movements along the edge of the ski to the snow more quickly and powerfully. A more flexible boot will absorb the pressure of moguls and off-piste terrain. A stiffer boot will require the skier to absorb the uneven terrain in the ankle, knee, hips, spine, and muscular system.
Boot Flex Numbers
It is important to note that there is no industry norm for boot flex. The current rating goes up to 150 for the stiffest race boots. Each manufacturer has its own standard, meaning a 120 flex in one brand may not be the same stiffness as a 120 flex in another brand, although they would be close. Finding the correct fit is primary, and forward flex is next. A final note, a boot will stiffen as the weather gets colder. The boot that you are flexing in the shop will be stiffer when you ski it on the hill. And a boot in January will be stiffer than the same boot for spring skiing in April.
My Current Boot Quiver
Having multiple boots is not required, but I have quite a collection going. I have three pair of Surefoot custom boots. One for backcountry, another for teaching on very cold days (it has a slightly wider toe box and is softer flexing), and the third pair with a “one-finger” high performance fit for teaching and for my days off. They all have a Lange shell with Surefoot X4 Pro or X5 Pro foam liners, Surefoot insoles, and a Thermic bootheater element under the ball of my foot.
I love the feeling of getting fitted and walking out to the shop with new shiny boots, almost as much as skiing them. Boots are the most important piece of gear I use, and I will invest more in boots than any other item. After you purchase new boots, you may find that they need a brief break in period to allow your feet to get use to the new fit. If you are new to orthotics it may take some time to get a good feel for them as well. The benefit of buying from a good bootfitter is that you can bring the boot back into the shop for on-going adjustments. If the adjustments don’t seem like they are working, it may be your technique. But not to worry, that is what upcoming blog posts and my upcoming book, Skiing: From the Bottom Up, will address.
