FAQ

How do I convert Birkenstock shoe size to Doc Martens?

Match by foot length in centimeters on each brand’s chart. Example: Birkenstock US 10 ≈ Doc Martens US 10.0 (about 27.1 cm). Then adjust for the specific model’s fit (runs big/small/narrow).

Is a Birkenstock US 10 the same as a Doc Martens US 10?

Not always. Labels can map to slightly different foot lengths. Use the cm column, then check model guides on both brands.

Which direction should I read first?

Start from the brand you already wear, then open the model fit pages linked below — lasts differ even when charts match.

Clothes sizing uses a separate compare path.
