Fitting and Adjusting Tips


How to measure your foot length

  • Stand with the heel to a wall and put a measuring tape under your feet

  • Read off the measured foot length in millimeters before your longest toe

  • If you are between two sizes, choose the next higher, because feet are minimally greater under load

You can determine your Birkenstock size by adding 31 to your U.S. women’s size and 33 to your U.S. men’s sizeYour feet should be able to move freely without your toes hitting the edge of the footbed.

Birkenstock footwear is made in European whole sizes.  As a brand founded in health and comfort we recommend a roomy fit that does not constrict feet or toes. This philosophy is reflected in the approximate size conversion charts below.


Two Widths
Select Birkenstock footwear is available in two widths. Generally, the Narrow width fits a narrow to regular foot and a Regular width fits a regular to wide foot.
Look for these footprint markings on Birkenstock footbeds and boxes to indicate shoe width.
