You can find a crucial size indicator on your ski boot by looking for a specific 3-digit number printed on the heel.
While ski boots are sized using the Mondopoint system (a measurement in centimeters), the size most commonly found printed on the boot itself is the Boot Sole Length (BSL). The BSL is the measurement of the entire length of the boot shell in millimeters and is essential for adjusting your ski bindings correctly.
Locating Your Ski Boot Size (BSL)
Finding your BSL is a simple process:
- Examine the Heel: Look closely at the outside or inside heel area of one or both of your ski boots.
- Spot the Number: You are looking for a 3-digit number.
- Note the Value: This number represents the length of your boot sole in millimeters.
Important Note from Reference: According to the reference provided, there will be a 3 digit number on the outside or inside heel of one or both of your boots. This number is your Boot Sole Length (BSL). Keep in mind that there shouldn't be a decimal (ex. 28.5).
What the Number Means
- The 3-digit number is the Boot Sole Length (BSL) in millimeters (mm).
- Common BSL values range roughly from 250 mm to over 350 mm.
- This number is critical for binding adjustment, not directly for choosing the fit size (which uses Mondopoint).
Example
If you see the number 305 printed on the heel of your ski boot, your Boot Sole Length (BSL) is 305mm.
Understanding your BSL is key for safety, ensuring your bindings are set to release correctly for your specific boot. While your Mondopoint size determines how the boot fits your foot, the BSL determines how the boot fits into the binding.
