Shoe Sizing
Mondopoint: The Only Sizing System That Makes Sense
2 min read · Updated July 2, 2026
Mondopoint isn't a competing sizing system so much as the answer to why we need sizing systems at all. It states foot length in millimeters. That's the entire specification.
The idea
A Mondopoint size is a pair of numbers: foot length in mm and foot width in mm, separated by a slash. 270/100 means a 270 mm foot at 100 mm width. Most consumer products drop the width and use just the length: 270, or 27.0 in centimeters.
Where it's used
- Japan and Korea (all footwear).
- Ski boots and mountaineering boots worldwide.
- NATO military boot procurement.
- Skate boots (mostly).
Why fashion ignores it
Retail is conservative. Athletic and fashion brands publish cm ranges but keep US/EU labels because customers recognize their number. A shift to Mondopoint would require re-educating every customer at once — no brand wants to lead that.
