CM to US Shoe Size
Choose adidas or Nike and the shoe category to see official measured-foot reference sizes, then verify the model’s fit.
Label comparison, not a foot-length chart. JP/CM is a printed shoe size label; it is not the length of your foot measured with a ruler. For a measured foot length in cm or inches, open the footwear maker's separate Foot Length or Heel-to-toe chart to choose a size. The US/UK/EU references here are approximate and vary by brand.

| 23.5 | 5.5 | 7 | 5 | 38 |
| 24 | 6 | 7.5 | 5.5 | 38.5 |
| 24.5 | 6.5 | 8 | 6 | 39 |

Choose the brand, then use measured foot length
Measure the longer foot from heel to longest toe and select adidas or Nike plus the men's or women's shoe category. The calculator compares your measurement with that maker's published physical-foot-length chart, not its JP/CM shoe-box label. Results are only starting references for the actual shoe you plan to buy.
For example, 26.2 cm falls between adidas heel-to-toe rows 25.9 and 26.3 cm: adidas men's US 8.5 or 9, or women's US 9.5 or 10. Nike's men's US 9 and women's US 10 are each listed at 10 5/16 inches (about 26.2 cm) in their own separate foot-length charts. Nike's men's-chart US Women's conversion column is not used to size women's shoes.
Two brands, two measurement sources
adidas publishes Heel-toe (cm) rows; Nike publishes Foot Length (in) fractions. Nike inch values are converted to approximate one-decimal-centimeter references, not falsely precise centimeter measurements. Measurements between published rows show both adjacent sizes; Nike advises sizing up, while adidas's guidance depends on the fit you prefer.
The table below serves a different job: comparing printed US, UK, EU and JP/CM shoe-size labels across common conventions. Printed JP/CM labels are not physical foot lengths. Other brands and models need their own source chart; fit and width also matter.
How this guidance is checked
These sources support the measurement method and help check real-world variation. They are not presented as one universal brand-size table.
- ISO 19407:2023 — Footwear — Sizing — Conversion of sizing systems — International Organization for Standardization (ISO). Measurement-first footwear methodology and the limitation that cross-system conversions are guidance rather than guaranteed fit.
- Men's Footwear Size Chart — Nike. Manufacturer cross-check showing that foot length, labeled CM values, width, and brand-specific sizing conventions are distinct concepts.
- Footwear Size Guide — adidas. Manufacturer cross-check across heel-to-toe length and US, UK, EU, and Japan-labeled footwear sizes.
Frequently asked questions
Does a measured 27 cm foot need JP/CM 27?
Not necessarily. JP/CM is a printed shoe-size marking, not a measured heel-to-toe value. Select a brand and shoe category in the measured-foot tool instead.
Why can Nike men's and women's sizes differ from a men's-chart equivalence?
The calculator reads Nike's own women's Foot Length chart when you choose Women's shoes; it never infers a women's physical-foot size from the men's chart's US Women's label row.
