Fitting Guide: Find Your Birkenstock Size & Fit

Birkenstock offers the original footbed in two widths: Regular and Narrow. This is to accommodate the differences in shape between an individual's feet and to provide optimum support and comfort.

HOW TO MEASURE

It's important to measure your foot accurately to find the right size shoe. To work out the size and width you will require, please follow these steps:

step one

Measure the length of your foot by standing on a flat surface with your full weight on your foot, then measure the distance from the back of your heel to the tip of your longest toe.

step two

Add 10mm to your foot length to allow your foot room to move. This will give you the footbed length you need to find your size.

step three

Measure the width of your foot across the broadest point. Compare your foot width measurement to the footbed width in the size chart below to see if you will need a narrow or regular width.

Example: Julie's foot measures 240mm long and 95mm wide. Julie adds 10mm to her foot's length to find she will fit comfortably into a Size 39 (250mm Footbed Length). At that size, the Regular Width footbed of 97mm will fit her foot properly.

Please Note: This is a guide only; shoes manufactured to standard measurements can't accommodate all the nuances and particulars to individual feet, however as a guide to find the closest fit it's a very useful tool.
