Birkenstock Boston Wire Buckle - Brown - 9.5 UK

These are not waterproof. While incidental contact with light moisture is usually fine, avoid wearing them in heavy rain or deep puddles to protect the cork and leather.

If the edges of the cork become dry, you can apply a thin coat of cork sealer to maintain the material's elasticity and prevent crumbling.

Birkenstocks generally have a generous fit. If you are between sizes, many users prefer to size down for a more secure fit.

It is recommended to apply a protective water-repellent spray before the first use to preserve the nubuck leather.

The footbed is integrated into the design. If the footbed becomes damaged or worn out, you may need to consult a professional cobbler who specializes in Birkenstock resoling.

The wire buckle is both an aesthetic design element and a functional tool that allows you to customize the tightness of the strap across your instep.

The cork-latex footbed requires a break-in period. Wear them for short intervals at home to allow the material to mold to your foot shape.

Adjust the metal wire buckle to the next notch to achieve a snugger fit across the bridge of the foot.

Use a specialized nubuck eraser or a fine-bristled brush to gently buff out dry stains. Avoid liquid cleaners unless specified for nubuck.
