Ski boots are sized in mondo (or mondopoint) sizing, which measures the length in centimeters of the boot's inner sole. Sound like we're speaking a different language? Use the conversion chart at the top of this page to translate your shoe size to your mondo size. In general, beginners want a boot that directly matches their street shoe size. Intermediate to advanced skiers should go a full size smaller. The BSL, or boot sole length, measures the length of a boot in millimeters, and you'll need it to match boot to binding or mount your new pair of skis. Keep in mind, this number can change between models even if they have the same mondo size. Still have questions? Don't hesitate to give us a call at (303)-237-7547 or email us at info@powder7.com. We're always happy to help you find the right pair of boots.

Here are some helpful tips to remember when sizing ski boots

  • Beginners should buy boots that correlate to their street shoe size
  • Intermediate to advanced skiers should size down
  • Ski boots should feel snug
  • You should try on a couple brands and models to find out what fits best
  • It’s okay if your big toe touches the front of the boot
  • Ski boot liners generally pack out and will feel larger after a couple of days skiing
