Is foot length in cm enough to buy online?

It is the best starting measurement, but lasts differ. Convert cm to a brand size, then apply the specific model’s fit verdict and width note.

Why does my cm size disagree between brands?

Charts round differently and lasts add volume or length feel. Use the converter per brand, then check the model guide before ordering.

Should I measure with socks on?

Measure the way you will wear the shoe. Thick socks and orthotics change volume — see the thick socks hub after converting length.

Foot length cm to shoe size — how to convert

Foot length (cm) to shoe size

Foot length in centimeters is the most portable measurement across brands — but brands still map cm to different lasts. A 27.0 cm foot is not automatically the same US size in Nike, Adidas, and New Balance once fit offsets and width enter the picture.

How to use cm on this site

Measure both feet (evening, socks you will wear) heel-to-longest-toe.
Open the cm → size converter and pick a brand chart.
Then open the model guide — apply that model’s runs-big / runs-small advice and width note.

The converter uses brand charts as a starting ladder. Model pages adjust for fit offsets (runs_small_by). That two-step flow is the point of this site — not a generic US↔EU farm page.
