Birkenstock Birki Flow Eggshell Regular

Sizing

How to Measure Your Foot Length

• Stand with the heel to a wall and place a measuring tape under your feet.
• Read the measured foot length in millimeters before your longest toe.
• If you are between two sizes, choose the next higher size as feet are minimally greater under load.

Birkenstock products are offered in European sizes. Please reference our Size and Width conversion charts below.

You can determine your Birkenstock size by adding 31 to your U.S. women’s size and 33 to your U.S. men’s size.

Note: Your feet should be able to move freely without your toes hitting the edge of the footbed.

Before trying them on, put one hand under the toe and one under the heel, then flex the footbed a few times. This will initiate the break-in period and help your new sandals feel comfy sooner.

Open all straps and step into the footbed. Close the straps comfortably, leaving enough space to allow your feet the freedom of movement. Exhale and enjoy.

For the first five or six times you wear your new footwear, limit the time to just a few hours. This allows your feet and body to gradually get used to the contoured arch support as well as the straps and buckles.
