For this product the fit is not indicated: below you find the measures of both If you have any doubts, write us before the purchase and we will confirm which one will come to you.

How to recognize the right fit

• A new Birkenstock looks wider than other shoes: the footbed leaves room for the toes to move naturally.
• The width is assessed with the straps or buckles already adjusted.
• With the right fit, there is a little space on the sides of the foot and the foot does not climb over the edges of the footbed.
• If you already have a pair of Birkenstocks, look at the imprint on the footbed: full = Narrow, outlined = Regular.
