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.
Your size specifications exceed the allowable limit. Please check your entry and try again. Or simply visit a BIRKENSTOCK store close to you so that we can help you further.

ADJUST STRAPS

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.
