Not sure what size ski boot you should be in? Let us do the work.

Instead of traditional shoe sizing, ski boots are sized in mondo (or mondopoint) sizing. The mondopoint measures the length in centimeters of the boot's inner sole. Sound like we're speaking a different language? Use our conversion chart and revolutionary Ski Boot Size Calculator to figure out your optimal ski boot size. Take a look at the advice below for additional notes on how you should size your boots, depending on skill level, personal preference, and navigating different boots on the market.

How to Size Your Ski Boots

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 (720)-674-5443 or email us at [email protected]. We're always happy to help you find the right pair of boots.

More Tips

  • 1. Beginners should buy boots that correlate to their street shoe size.
  • 2. Intermediate to advanced skiers should size down
  • 3. Ski boots should feel "suspiciously snug", as they'll pack out and get more roomy over time.
  • 4. All brands fit a bit different, so try on a few different models to find out what fits best.
  • 5. Perfect sizing would be your toes gently kissing the edge of the liner when standing up straight, with your toes pulling away as you flex the boot. No crunching or curling!
