Size Guide
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:


Measure the length of your foot whilst standing on a flat surface with your full weight bearing down, measure the distance from the back of your heel to the tip of your longest toe.
Measure the width of your foot across the broadest point. Compare this measurment to the footbed width measurements shown on the size chart to see if you need a narrow or regular width.
Example: Jackie's foot measures 250mm long and 95mm wide. She looks at her foot length in the below table and finds she will fit comfortably into a size 39 (250mm Footbed Length). At that size, the Regular Width footbed of 97mm will fit her foot perfectly.


If you are after a size chart, you will find a link to this located above the price of each individual product or alternatively you can click the links below.

    1st Order

    This was the first time ordering shoes online. I ordered my usual shoe size, they fit perfect. Nice style shoe, very comfortable, bit firmer than what i usually wear to work (allegra’s) so need to wear them in. Very happy with the purchase, will order again from Birkenstock Hahndorf. Had a speedy delivery and exceptional service.

    Birkenstock Iona

    Shipping was quick and the overall experience was very easy. The shoes are extremely comfortable. I am glad I read reviews and went up a size as they are definitely a smaller fit than my Arizona’s. I went up one full size and they are perfect fit. Very comfortable and look nice as a work shoe.
