Shoe box CM ≠ your foot CM. The CM printed on a shoe is a size marker — some brands print foot length, others the inside length of the shoe. Always measure your bare foot.
Frequently Asked Questions
What US size is 25 cm?
25 cm = US men's 7.5 (EU 40.5, UK 7) or US women's 9 (EU 39.5, UK 7).
What US size is 26 cm?
26 cm = US men's 9 (EU 42, UK 8.5) or US women's 10 (EU 40.5, UK 8).

Why do men's and women's US sizes differ for the same CM?
US sizing uses separate number scales for men and women. The same 26 cm foot is a US 9 on the men's scale and a US 10 on the women's scale.
Is foot CM the same as shoe CM size?
Not always. Some brands print the foot length the shoe is made for, while others print the inside length of the shoe, which is 1–1.5 cm longer to leave toe room. Always measure your bare foot and compare it with the brand's chart.
