Shoe Size Conversion Calculator
This uses a general size chart — real fit still varies by brand, since every brand builds shoes on its own "last" (mold). When precision matters, measure your actual foot length in cm and compare it against that specific brand's own size chart.

Frequently asked questions
Why does my shoe size vary between brands?
Every brand builds shoes on its own "last" (the 3D mold that shapes the shoe), so the same labeled size can fit differently across brands — a US 10 in one brand isn't necessarily a US 10 fit in another. This chart gives the general standard conversion, not a brand-specific guarantee.
What's the most reliable way to find my size in a new brand?
Measure your actual foot length in centimeters and compare it against that specific brand's own published size chart, since brand charts account for their particular last.
