Birkenstock products come in European sizes, and you can determine yours by adding 31 to your U.S. women’s size or 33 to your U.S. men’s size. Ideally, your feet should be able to move freely without your toes hitting the edge of the footbed. You can use this Birkenstock size chart to find out the perfect Berkin size for your feet.

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.

FAQs

Let’s look at some of the common questions around Birkenstock.

Why do Birkenstock shoes look wide?

They look wider than most shoes because the design follows the natural shape of the foot. Many shoe styles feature a narrow toe area, which not only compresses the toes but throws the foot out of alignment. The shape of your Birkenstock shoes guides the toes and feet into correct alignment so the weight is evenly distributed and good posture is possible.

 Why do the soles feel so firm? Is there a break-in period?

Some people find their Birkenstock shoes immediately comfortable. For others, it takes a few hours a day for a week or two to break them in. Although the shoes may feel ridged at times, remember that firm support is essential for the orthotic benefits of Birkenstock footwear. 

They will become more flexible with wear. The uppers will become more supple and the footbeds will adjust slightly to your feet. If your feet are unaccustomed to the contoured footbed, start gradually. wearing your Birkenstock footwear no more than 1-2 hours a day for around 7-14 days.

Will Birkenstock footwear make my feet spread?

Birkenstock shoes will not give your feet a new shape! Feet that have been squeezed into traditional shoes may resume their original natural shape, depending on the flexibility of your feet. 

How long does Birkenstock last? Are they guaranteed for any period of time?

While there is no set guarantee period, with proper care, Birkenstock footwear can provide years of comfort. Everything that goes into the shoe is top quality – from the suede, jute, and cork of the footbed, to the leather, suede, and nubuck used to create the uppers. The result is footwear that’s an excellent value – comfortable and remarkably durable. Sole Central does give a 60-day money-back guarantee.

Do these shoes mold to my feet?

The Birkenstock footbed is made of resilient cork and latex that is precisely molded to create the best possible environment for your feet. As you wear them, they actually adapt to your feet and vice versa-which means that the more time you spend in Birkenstocks the more comfortable they become.

Why do the straps feel so loose? Shouldn’t they be tighter?

Birkenstocks are meant to be worn loosely. Support comes from the footbed -not tightly secured straps. Wearing them loosely allows your feet to move naturally. It also improves circulation. Back straps are worn to tightly push the feet forward, preventing them from resting naturally in the footbeds.
