Women’s sizing Birkenstock uses a single EU scale for everyone — there is no separate women’s US gap on the box. Buy the same EU size you wear in other EU-labelled Birkenstock shoes, then apply this model’s fit note (True to EU size; Narrow if slim foot).
Offset confidence: high

Convert your women’s size

Birkenstock labels in EU unisex — the same EU for everyone. Don’t apply a generic 1.5 US women’s→men’s rule; match EU/cm.

Why this brand differs

Birkenstock labels in EU unisex — the same EU for everyone. Don’t apply a generic 1.5 US women’s→men’s rule; match EU/cm. Generic converters that always subtract 1.5 or 2 will be wrong for some brands. We only publish gaps confirmed against brand charts (cm-anchored).

Model fit warning

true to size — True to EU size; Narrow if slim foot. Width: Same footbed family as Arizona.

Women ↔ men chart

US Men (w/ fit) applies this model’s runs_small_by (+0). cm is the most reliable anchor when labels conflict.

Use the brand’s UK/EU/cm chart on the model fit page instead of a women’s→men’s US subtract.
