Birkenstock Shoes / Boots / Footwear Size Chart, Advice & Fit Guide

EU Sizes
Birkenstock sandals, shoes and boots are designed in Europe so use EU sizing.

International Sizes
Birkenstock's conversion of sizes from EU to UK, US and Mondo contains numerous errors.  We have added "Absolute" columns to the table below showing the correct size conversions.  We therefore recommend:

    ●  If you have owned Birkenstock before, simply order the same size again.

    ●  Use EU sizing.

    ●  If using UK, US or Mondo refer to the Absolute conversions for greater accuracy.

On Our Website.....
On our website we use Birkenstock sizes (even though they are not always correct) because these are what appear on the shoe boxes and the shoes themselves.
