Size Guide

Birkenstock footwear is listed in European sizes and built around a contoured footbed. Use the conversion charts and width guide below to find your best fit. Your toes should never touch the edge of the footbed—aim for about ¼ inch (6mm) of space around your foot.

How to Measure & Test the Fit

Measure Foot Length

Stand with your heel against a wall. Measure from the wall to the tip of your longest toe in millimeters. Add 10mm for room to move.

Match to Chart

Use the footbed length column to find your EU size. If between sizes, choose the next size up—feet expand slightly under body weight.

Check Width Symbol

Look at the footprint printed on the footbed. Outlined = Regular/Wide. Filled = Narrow. Choose the width that matches your foot shape.

Flex Before Wearing

Before trying them on, flex the footbed by placing one hand under the toe and one under the heel. This begins the break-in process.

Breaking In Your Birkenstocks

Start Loose

Keep straps loose at first to avoid pressure points. Your feet need time to adjust to the contoured footbed.

Wear Gradually

Wear them around the house for 1–2 hours at a time. Gradually increase wear time as your feet adapt.

Tighten as They Mold

As the footbed begins to mold to your feet, you can tighten the straps for a more secure fit.

Check Toe Space

Your toes should never touch the edge of the footbed. Aim for about ¼ inch (6mm) of space around your foot.

Fit Note: Birkenstock shoes may feel roomy at first—this is intentional. The footbed is designed to let your toes spread naturally, and the upper will mold to your foot over time.

If your straps feel too loose even when tightened, a cobbler can punch extra holes. If there is significant room on either side of your foot in the footbed, you are most likely a Narrow width.

All measurements are approximate and based on European sizing. Footbed lengths include a small allowance for foot movement.
