Birkenstock Gizeh Sandals - Black - UK 3

No, Birkenstock Gizeh sandals with a cork footbed and Birko-Flor® upper are not waterproof. While they can handle light splashes, prolonged exposure to water should be avoided as it can damage the cork and other materials.

Birkenstock sizing is typically true to size in EU measurements. Ensure your heel sits comfortably in the heel cup and your toes don't touch the front rim. Refer to a Birkenstock size chart for accurate measurements.

Birko-Flor® is a durable, synthetic material developed by Birkenstock. It's skin-friendly, tear-resistant, and easy to care for, offering a high-quality alternative to leather with a similar look and feel.

While traditionally worn without socks, some individuals choose to wear Birkenstock sandals with socks for comfort or style, especially in cooler weather. It's a personal preference.

The break-in period varies for everyone but typically lasts a few days to a couple of weeks of intermittent wear. During this time, the cork footbed gradually molds to the shape of your foot, providing personalized support and comfort.

If you notice the cork edge looking dry or losing its sheen, it's a good time to reapply sealant. For regular wear, every few months or once a season is a general recommendation to maintain the cork's integrity.

Birkenstock footbeds require a break-in period. Wear them for short durations initially, gradually increasing wear time to allow the cork to mold to your foot's unique shape. Ensure the strap is adjusted correctly, holding your foot securely but not too tightly.

Adjust the buckle on the strap. The strap should comfortably hold your foot in place without restricting movement or leaving too much space around your foot. Your heel should sit flush in the heel cup.

This can sometimes occur if moisture is trapped between your foot and the footbed, or if the strap is rubbing. Try applying a small amount of foot powder to the insole or ensuring your feet are dry. Check the strap adjustment; it might be too loose or too tight.

Cork can dry out with age and exposure. Apply a thin layer of specialized cork sealant (available from Birkenstock or shoe repair stores) to protect and moisturize the cork. Avoid leaving sandals in direct sunlight or hot places for extended periods.

For Birko-Flor®, gently wipe the stained area with a damp cloth. For more stubborn stains, use a very mild soap solution, then wipe clean with a fresh damp cloth and let it air dry completely away from direct heat.
