Birko-Flor

Birko-Flor is a durable and easy to clean synthetic material, made to sit comfortably against the skin and used exclusively by Birkenstock.

Sustainable Cork

The Birkenstock cork footbed is legendary, not only for its comfort and support, though also for its sustainability. The cork is responsibly sourced from the outer layer of the cork oak tree. Sections of the thick bark are carefully removed without harming the tree, allowing it to regenerate and be re-harvested every 7-9 years. A single cork oak tree can produce 100 - 200 kg of cork in its lifetime!

Footbed Features

The anatomical design of the Birkenstock footbed follows the natural contours of your feet to strengthen, support, activate, stabilise and align. Boasting features such as a raised footbed edge, toe grip bar, arch support (including transverse, metatarsal, interior and exterior longitudinal arch support), heel mould, deep heel cup, and plenty of toe room, it's no wonder the humble Birk is coveted the world over.

Birkenstock Classic Fit Details

This Birkenstock runs true to size. We recommend sticking with your usual size and refer to the Size Guide if you are unsure.

This Birkenstock provides support features including longitudinal, metatarsal and transverse arch support, a heel cup and mold, and raised toe bar for basic orthotic support.

Birkenstock Classic Size Guide

How to find your size

Step 1

Stand on a level floor with your heel up against the wall or straight edge.

Step 2

Place a ruler or measuring tape on the floor under your foot or alongside it, with your heel at 0cm.

Step 3

Measure the length of your foot from your heel to the end of your longest toe (yes, even if it's your second toe).

Step 4

Measure both feet and go with the length of your longest foot if they are different.

Step 5

Add 10mm to your foot length to allow your foot room to move. This will give you the footbed length you need to find your size.

Step 6

Check out the size charts below to find your size in EU (all Birkenstock sizes are listed in EU).

Step 7

Measure the width of your foot across the broadest point. Compare your foot width measurement to the footbed width in your size to see if you will need a narrow or regular width. (If you are in between sizes, we recommend going for the larger size)

Most Birkenstock styles are available in 'regular' or 'narrow' width.

Narrow width is suitable for narrow to slender feet.

Regular width is suitable for normal to wide feet.

If you already own a pair of Birkenstocks or are trying them on in store - check out the little foot symbol on the footbed. If the foot is coloured in, it's a narrow (N). If it's just an outline of a foot, it's a regular (R).

    Great purchase

    I love my new Madrids. Friends asked how I’d like the back of the sandal flipping up like a pair of things but they are so comfortable and fit just like my beloved Arizonas always have once worn in. Perfect with any outfit in the summer time and will purchase again when the time comes. Also in love with the colour!
