BOOT SOLE LENGTH: What is it?
Your boot sole length is the actual length of your ski boot, in millimeters. This is the number that our ski techs will use to mount your bindings. While you’ll still need a final adjustment done before you can ski, providing us with your boot sole length is absolutely crucial if you’d like us to send your skis pre-mounted with your bindings.
HOW DO I FIND IT?
Finding your Boot Sole Length (BSL) is easy. On your ski boot, there will be a 3 digit number on the outside or inside heel of one or both of your boots. Keep in mind that there shouldn't be a decimal (ex. 28.5). If the number you see has a decimal, then you’re probably looking at your Mondo Point size which isn’t accurate enough to use when mounting bindings. Other hints that you're looking at the Mondo Point and not the BSL would be if it looks something like "270/275" or if the number is found on the bottom of the boot. If you’ve looked all over and still can’t find your BSL, it’s also acceptable to measure along the bottom of the boot from the very tip of the toe, to back of the heel- just make sure you measure in Millimeters!
ISN'T THE BSL THE SAME AS MONDO POINT?
Nope! The mondo point size is the generic boot size that every boot maker uses it. Think of it as a shoe size, like a "size 11" for example. The boot sole length is the literal length from toe to heel of that boot, measured in millimeters. It's entirely possible and very common for boots with the same Mondo Point to have different Boot Sole Lengths. Because ski bindings are so precise, it's crucial to have them mounted to the BSL and not the Mondo Point.
