FAQs

Are these shoes waterproof?

No, the suede upper is not waterproof and should be kept away from heavy rain and deep puddles.

Can I wear these without socks?

Yes, the suede-lined footbed is designed to be soft and comfortable against bare skin.

How do I know if they fit correctly?

Your toes should not touch the front rim, and your heel should sit comfortably within the deep heel cup.

Can I replace the footbeds?

While the footbed is integral to the construction, an authorized cobbler can often resole or refurbish worn-out Birkenstocks.

Is the size 9.5 UK standard?

Yes, these are sized according to standard UK sizing for a tailored adult fit.

How long does the break-in process take?

Most users find the footbed reaches optimal comfort after 10 to 14 days of regular wear.

Troubleshooting

Footbed feels too hard during first use

This is normal; wear the shoes for short periods daily to allow the cork to mold to your foot shape.

Suede appears dusty or flattened

Use a specialized suede brush to lift the nap and restore the texture of the material.

Buckle strap feels loose

Tighten the adjustable buckle to the next notch to ensure a more secure fit against the instep.

Setup, Compatibility & Care

New Birkenstock owners should be aware that the cork footbed will feel firm initially. It is recommended to wear them for only a few hours at a time during the first week to allow the cork to warm up and shape itself to your specific foot geometry. For maintenance, keep the suede away from direct heat sources. If the suede becomes dirty, use a dedicated suede brush to remove loose dust. To clean, wipe the surface gently with a slightly damp cloth and let them air dry in a cool, ventilated area—never use a dryer. Apply a suede-specific water repellent spray annually to protect the material from light moisture.
