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.

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).

    Soft footbed winner

    Purchased because this was part of the limited choices in soft foot bed. First time I’ve had the soft ones & they are so much more comfortable as I have bone issues in my feet. Also love the pattern.
