If you are on the hunt for a pair of Birkenstock sandals and want to make sure you get the perfect fit, then you’ve come to the right place. You are going to own these sandals for the long term so you want to make sure you get the fit right up front. So how should your Birks fit?
To properly fit your Birkenstock sandals, you want to fit your toes, your heel and the straps. Your toes should be an 1/8 to 1/2 inch (3mm to 13mm) from the top of the sandal. Your heel will sit into the heel cup with similar distance to the edge as your toes. The strap should have 3/8-inch (10 mm) space across your foot.
Here is an image the shoes these three points so that you have a better idea visually.
Before we dig into proper fitting of your chosen Birkenstocks, it’s important to review the sizes available so that you can choose the proper Birkenstock sandal for your feet.
Birkenstocks are sized using the European sizing system. Here is a chart to help you to convert if you are more familiar with a different sizing method.
Most Birkenstock sandals are available in either standard width or narrow width. The majority of Birkenstocks buyers choose standard width, and these are fine for your feet. If you have narrow feet, then you can also choose the narrow width sandal instead.
The image above illustrates the difference narrow and standard width Birkenstocks in women's and men's sizing.
To evaluate the proper fit of your Birks, as mentioned above, you should take a look at 3 important points on your sandals (note for the Giseh sandals, you can also evaluate that strap anchor location too):
Additional methods to fit your Birks:
The perfect fit for your Birkenstocks means that your toes are not to close to the end of your sandals. There should be some space between the tip of your toe and the end of the sandal. Look for 1/8th of an inch (3 mm) to 1/2 of an inch (13 mm).
To fit your heel properly, your heel should sit comfortably in the sandal heel cup with approximately the same space to the end of the sandal as your toes would to the end of the sandal. Therefore, look for 1/8th of an inch (3 mm) to half an inch (13 mm) distance from your heel to the end of your sandals.
The strap should feel comfortable, there should be approximately 10 mm of space (3/8th of an inch) form the top of your foot to the sandal strap.
Too much space and your foot will flop around, too little space and your foot will feel constricted. This allows for movement of your foot in the sandal as you move and walkabout.
For Birks like the Giseh, you will have a strap anchor that comes up between your big toe and first toe. You will want to have some space between the strap and the fleshy part that connects your toes.
In addition to the above, you can also make sure you have the proper length Birks by checking the toe bar fit. When you place your foot snuggly into the heel cup and roll your foot forward over the footbed, your toes should go over the toe bar allowing the bar to fit comfortably under toe knuckle.
If your toes are sitting on top of the bar, the sandal is too long. If your toes are too far past the toe bar, then the shoe is too short.

Another option would be to use or purchase a Brannock to measure the size of each foot.
This video describes the different elements making up the Birkenstock footbed. YouTube.
The shaped heel cup is shaped to support and stabilize your foot upon hitting the ground. This gives the foot the correct orthopedic position
The lateral longitudinal arch support is designed to support the area of your foot between the mid and rear of your foot. It also helps to improve the proper position of your foot in the footbed.
The medial longitudinal arch support underpins the arch of your foot to support your arch and prevent lowering of your inner foot edge. Effectively supporting your foot arches.
The traverse arch support is in the middle area of the sandal close to the toe bar, stabilizes the midfoot, and relieves the ball of the foot.
The toe grip supports the natural gripping motion of your toes and promotes the natural extension of your toes while walking. You’ve probably noticed how your toes tend to curl up when you wear flip-flops while walking. This toe grip encourages your toes to stretch out rather than curl up.
The front footbed edge protects the toes and the entire foot.
Overall the design of Birkenstock sandals combining all of these components is designed to spread the weight evenly over the surface of your entire foot, rather than one part or area of your foot like other shoes do.
It is my hope that the information provided here can help to make sure you find the perfect fit for your Birkenstocks. Your Birks should fit comfortably. Birks are designed to last and when you own a pair of Birks that fit properly, they will mold to your feet over time and you will love them.
