The Short Answer
A 26 cm foot wears a US men's 8, US women's 9.5, UK 7.5, or EU 42. Centimeter sizing — often called Mondopoint — is the most direct system because the number is simply your foot length, and every other scale is built from it.

How to Measure Your Foot
- Stand on a sheet of paper with your heel against a wall.
- Mark the tip of your longest toe and measure to the edge of the paper.
- Measure both feet in the evening, when feet are slightly larger, and use the bigger number.
Enter that measurement in the converter above — select CM as the starting scale — to see your size on every system at once.

Beyond Length
Foot length gets you close, but width and arch shape affect fit too. If you are between sizes or have wide feet, sizing up a half size is the usual advice — and brand-specific charts always win over generic conversions.
Frequently Asked Questions
Should I measure my foot with socks on?
Measure the way you plan to wear the shoes. For athletic shoes, wear your usual socks; for dress shoes, thin socks or bare feet give the truer length.
What if my feet are two different sizes?
That is very common. Fit the larger foot and use insoles or heel grips in the other shoe if needed.
Is Mondopoint the same as CM sizing?
Essentially yes — Mondopoint expresses foot length in centimeters (sometimes millimeters) and is used by the military and many ski-boot and outdoor brands.
How much growing room should kids' shoes have?
About a thumb's width — roughly 1 to 1.5 cm — beyond the longest toe. Measure every few months, since children's feet grow fast.
