The Care and Keeping of Your BIRKENSTOCK Cork Footbed

When you purchase a pair of BIRKENSTOCK sandals, you are not simply buying footwear. You are buying a system of orthopedic support that has been refined in Germany for over two centuries. The heart of this system is our cork-latex footbed, a material that molds to the unique contours of your feet with wear. This is why proper care is not about cosmetics—it is about preserving the structural integrity of the footbed, the very foundation of the walking experience we engineer.

The Anatomy of Your Footbed

Every BIRKENSTOCK footbed is built on a base of jute, which is then layered with a mixture of natural cork and latex. This blend provides firm support while remaining responsive to your body's weight and movement. The footbed is then wrapped in a breathable upper material—whether that is the smooth oiled leather of our classic Arizona or the soft microfiber of Birko-Flor—and finished with a shock-absorbing EVA outsole. Understanding this construction is the first step in understanding how to care for your sandals.

Why Your Footbed Cries Out for Attention

The most common issue we see is dried, cracked cork. This happens when the natural oils in the cork evaporate, often due to excessive heat or prolonged exposure to water. A cracked footbed is not just an eyesore; it compromises the supportive structure that makes BIRKENSTOCK unique. To prevent this, you need to feed the cork, just as you would condition a leather saddle.

The Simple Ritual of Cork Sealing

We recommend sealing your cork footbed every two to three months, depending on how often you wear your sandals. Use a high-quality cork sealer, preferably one that is colorless and non-greasy. Apply a thin, even layer to the exposed cork edges of the footbed, using a soft cloth or brush. Allow it to penetrate for a few minutes, then buff off any excess. This simple ritual will keep the cork supple and prevent it from drying out.

Cleaning Your Footbed: A Gentle Approach

The footbed is where your foot rests, and it will inevitably pick up perspiration, dust, and dead skin cells. For routine cleaning, a soft brush or damp cloth is sufficient. For a deeper clean, mix a small amount of mild soap with water, dampen a cloth, and gently wipe the footbed. Do not soak the footbed, and never put your BIRKENSTOCK sandals in the washing machine. After cleaning, stuff them with newspaper to help them hold their shape and allow them to air dry away from direct heat or sunlight.

Uppers: Respect the Material

The material of your upper—whether it is the supple oiled leather of the Boston clog, the smooth nubuck of the Madrid, or the durable microfiber of Birko-Flor—requires different care. Oiled leather benefits from a leather conditioner, applied sparingly with a soft cloth. Nubuck and suede need a suede brush to revive the nap and a water-repellent spray to protect them from the elements. Birko-Flor, a high-quality synthetic, is the easiest to maintain; a simple wipe with a damp cloth will usually suffice. Always check the care instructions that came with your sandals.

Break-In Period: Patience is a Virtue

One of the most common questions we receive is about the break-in period. The cork-latex footbed is firm by design, and it will take time for it to conform to the shape of your foot. During this period, which can last from a few days to a few weeks, you may feel some pressure points. We advise you to wear your new BIRKENSTOCKs for short periods initially, gradually increasing the time. This allows the footbed to mold gradually, ensuring a perfect fit. Do not be tempted to force the process with heat or moisture; this will only damage the cork.

Width Matters: A Proper Fit is the First Step in Care

Before you even begin your care routine, you must ensure you have the correct width. BIRKENSTOCK offers two widths: Regular and Narrow. A proper fit means your foot sits fully within the footbed, with no overhang at the sides or heel. If your foot spills over the edge, the footbed will not mold correctly, and you will place undue stress on the cork. Visit a BIRKENSTOCK retailer to have your feet measured professionally, or use our online fitting guide.

Storage and Everyday Habits

How you store your sandals is just as important as how you clean them. Avoid leaving them in a hot car or near a radiator, as heat will accelerate the drying of the cork. Store them in a cool, dry place, ideally with the footbed facing upward to prevent warping. If you wear them only seasonally, consider placing them in a cloth bag to protect them from dust. With these simple habits, your BIRKENSTOCK sandals will serve you well for many years, providing the natural support that has made them a global icon of orthopedic footwear.
