Collection: Women's Boston
Optimal Fit In Two Widths
For your comfort and support, we offer our original footbed in two widths: 'Regular' for normal to wide feet and 'Narrow' for slimmer feet.
The width of your Birkenstocks is indicated by the footprint shape next to the size.
Choosing the correct fit will keep your feet happy, prevent pressure or rubbing in the wrong places and extend the lifespan of your shoes.
Most people with a normal to wide foot will be comfortable in a Regular width fitting.
If you usually seek a narrow fitting shoe or have a particularly slim foot shape, the Narrow width may be more suitable for you.
Size chart
These measurements are footbed dimensions.
We recommend choosing a footbed size by adding 10mm to the length of your foot, and selecting narrow or regular based on your foot width.
