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.

Italy to US: use the printed EU label when present

Nike Italy's men's footwear chart pairs EU 42.5 with US Men's 9. For a shoe actually marked EU 42.5, this is an example of reading a European-number row on the Italian retailer's chart—not a unique Italian sizing formula.

If the product is in another manufacturer's Italian collection, confirm its own EU/US pairing. A size label '42' should not be treated as measured foot length in centimeters.

How to use the general reference chart on this page

The table above compares approximate US men, US women, UK, EU and JP/CM printed shoe-label references. It does not provide a direct country-specific size column. The brand-specific example above supplies a checked local-label answer; confirm it against the actual product chart before buying.

Keep foot length measured from heel to longest toe separate from CM/JP or millimeter numbers printed as shoe size labels. Those may be different quantities even when both contain the unit cm or mm.

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.
  • Men's footwear size chart — Nike Italy. Italy-market EU and US men's label pairing for Nike; not a universal Italian-only sizing method.
