Fitting ski boots yourself involves checking the shell fit to ensure proper sizing before even considering the liner. This initial shell fit assessment helps determine if the boot's overall size is appropriate for your foot length and width.
Here's how you can assess the shell fit of ski boots:
-
Remove the Liner: Take the liner out of the ski boot shell. You need to assess the shell without any interference from the liner.
-
Insert Your Foot: Put your foot into the bare shell. Make sure you're wearing thin ski socks (the type you'd actually ski in).
-
Slide Forward: Slide your foot forward inside the shell until your toes just touch the front. Don't jam them in, just a gentle touch.
-
Check Heel Space: With your foot in this position, check the space between your heel and the back of the shell.
-
The Finger Test: This space is crucial. Most skiers should have approximately 1 to 2 finger's width of space (approximately 15-30 millimeters) between their heel and the back of the shell.
-
Too Much Space: If you can fit more than two fingers easily, the boot is likely too large. A boot that is too large won't offer sufficient control.
-
Too Little Space: If you can barely fit one finger, the boot is likely too small. A boot that is too small can cause discomfort and circulation issues.
-
-
Consider Width: While checking the length, also pay attention to how your foot feels width-wise inside the shell. Are your toes cramped? Is there excessive room on either side of your foot?
Important Considerations:
- This is a shell fit assessment, not a final boot fit. It's a preliminary check to determine if the boot is even in the right ballpark.
- Ideally, you should have this done by a professional boot fitter. They have the expertise and tools to accurately assess your foot and boot fit. A professional fitter can also make adjustments (shell grinding, liner molding) to fine-tune the fit.
- This self-assessment is best used as a guide to help you select a few models to try on with a boot fitter or to assess your current boots.
- Aftermarket footbeds/orthotics should be used during shell fitting, as they take up volume and will affect fit.
- Boot flex is also an important factor to consider for performance and comfort but will not influence how to do a shell fit.
In summary, fitting ski boots starts with assessing the shell size by checking the heel space when your toes are touching the front of the boot's shell, ensuring a comfortable and performance-oriented fit. While you can perform the initial steps, consider consulting a professional for optimal results.
