FIND YOUR PERFECT FIT

INDIVIDUAL COMFORT FOR THE WELL-BEING OF YOUR FEET

The right footwear, the anatomically shaped footbed and a perfect fit form the basis for healthy feet and a healthy gait. With a correct fit sore feet, pressure points or malpositions can be prevented. If you are uncertain about the exact size and width of your next pair of BIRKENSTOCKS, we will gladly help you find the perfect fit – from measuring your feet to adjusting the straps.

To guarantee optimum comfort, we offer our original footbed in two widths: “regular” for normal to sturdy feet and “narrow” for slim and more narrow feet.

To determine the perfect size for your sandals, please choose whether the calculation is for kids’ or adults’ feet and enter the measurements for each foot. You can find more information in our size chart.

That’s how it’s done: we recommend using a pencil or a ball pen. A thick pen, such as a felt-tip or marker, can distort the result.

Place your foot on the footbed while standing upright.

Walk a few steps. Should the straps be too tight or too loose, readjust them. The straps at the left and at the right foot do not necessarily have to be adjusted the same way. Check your straps again after a few days, as the upper can stretch a little over time.

Our recommendation: don’t wear new sandals longer than a few hours at a time to break them in slowly

Size information

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
