If you're shopping for ski boots online, you’ve probably seen terms like LV, MV, and HV—but what do they actually mean? These abbreviations refer to the “last” of the boot, which is an industry term for how wide the boot is across the forefoot, usually measured in millimeters (mm). Let’s break it down in simple terms.
What is Ski Boot “Last”?
Ski boot “last” is the width of the inside of the boot at the forefoot, measured in millimeters. It’s one of the most important factors when it comes to comfort and fit. A good fit means better control, warmer feet, and less pain on the mountain. Generally a boot with a wider last across the forefoot will also have more room in other key areas such as the instep, ankle, and leg shaft.

Less Common Lasts
- Ultra Low Low Volume - Often found on race specific boots with lasts less than 96 mm.
- Extra High Volume - These boots are the widest of the wide made to accommodate those that cannot fit in a regular high volume boot.
*Please note manufacturers often post the width in mm of a ski boot at a sample mondopoint size of 26.5.
How Do I Know My Foot Width?
It is best to get fitted in person by a qualified boot fitter. However, if you can’t get to a boot fitter in person, try this:
-
Trace your foot on paper while standing.
-
Measure the widest part (across the ball of the foot).
-
Compare it to your mondopoint size and find the width that matches.
Still unsure? Most first-time buyers are safe starting with MV boots, which work for the widest range of skiers.
Final Tips for Online Boot Shoppers
-
Don’t size up for comfort—choose the right last instead.
-
It is easier for a boot fitter to make a boot that is too snug more roomy than to add material to take up space.
-
Look for brands known for fitting your foot shape in the past..
-
If in doubt, contact a ski boot fitter (like us at The Pro Ski and Ride!) for advice.
