How Mondopoint and US sizes relate

Mondopoint (ISO 9407) labels footwear by the foot it fits: the foot length in millimeters. It is most often seen on ski and snowboard boots. Korean sizes are also given as foot length in millimeters, and Japanese sizes follow the same idea in centimeters.

Because Mondopoint is the foot itself, converting to US means adding the toe room back: a men’s US size is about 3 × (mm ÷ 25.4) − 22, and a women’s size 1.5 higher. Boots are often labeled in 5 mm steps, and ski-boot shells fit differently from street shoes, so treat the US figure as a starting point.

How every size system is defined

How to measure your foot

1. Measure late in the day, when feet are at their largest, wearing the kind of socks that will be worn with the shoes.
2. Put a sheet of paper on a hard floor against a wall and stand on it with the heel touching the wall.
3. Mark the tip of the longest toe on the paper. It isn’t always the big toe; keep the pen upright.
4. Measure straight from the wall to the mark, in centimeters or inches.
5. Do both feet and use the longer one. Enter that length in the converter above as a foot length.

The foot lengths on this page are bare-foot measurements. The shoe itself is longer, so don’t measure an old shoe or insole and treat that as your foot length.

Width and between sizes

Length is only half of fit. US shoes are often sold in widths marked with letters. A common convention: men’s standard width is D, wide is 2E and extra wide is 4E; women’s standard is B and wide is D. Letters vary by brand, and many brands use words such as narrow, regular and wide instead.

If your measurement falls between two sizes:

• Measure late in the day, when feet are at their largest.
• Let the longer foot decide; most people have one foot slightly longer than the other.
• Think about the socks: thick hiking or winter socks take up more room than thin dress socks.
• Think about what the shoe is for. People often choose a little more room in athletic or hiking shoes than in dress shoes.
• If you can, try both sizes on and walk around before deciding.

Using a brand’s own chart

For a final answer, look up the official size chart on the brand’s own website, for the exact product line if it has one. Compare by foot length in centimeters rather than by size number: find the brand’s row for your measured foot length and read the size from there.

Size numbers don’t always mean the same length from one brand to the next. Some brands, particularly in sportswear, list EU sizes about half a size higher than generic charts like this one, and some use their own offsets between UK and US sizes. This page doesn’t guess any brand’s offsets; it shows one consistent reference chart.
