Enter Mondopoint, US or EU — the others update automatically.
Ski boots use Mondopoint sizing — a system where the size number equals your foot length in centimeters. This ski boot size converter converts Mondopoint to US shoe size and EU shoe size instantly. Mondopoint is used by all major ski boot brands including Salomon, Atomic, Rossignol, Head, Tecnica, and Lange because it is far more precise than regular shoe sizing for the critical fit requirements of alpine skiing.

Frequently Asked Questions
What is Mondopoint sizing?
Mondopoint is your foot length in centimeters. A boot labeled 27.0 or 270 fits a foot that measures 27 cm heel to longest toe. It is the international standard for ski boots.
Should ski boots feel tight at first?
Yes. A correct performance fit feels snug to slightly uncomfortable initially. The liner packs out (compresses) by roughly half a size over the first 5–10 ski days.
What Mondopoint is a US size 9?
US men's 9 = Mondopoint 27.0 = EU 42. Use the converter above for any other size.
What is flex index in ski boots?
Flex index (e.g. 70, 100, 130) indicates stiffness. Lower = more flex, better for beginners. Higher = stiffer, better for advanced skiers. Get the right Mondopoint first, then choose flex for your ability level.
Can I use my regular shoe size to buy ski boots?
Not reliably — regular shoe sizes vary too much between brands. Always measure your foot in centimeters and use the Mondopoint value, or have your foot measured at a ski shop.
