Birkenstock Slippers & Sandals - Grey - Silver - UK 4.5

Birko-Flor® is a brand name for Birkenstock's synthetic upper material, typically made from a blend of acrylic and felt fibers, designed to mimic the look and feel of leather.

The ideal fit means there's a small space between your toes and the edge of the footbed, and a similar space at the heel. The straps should hold your foot securely without digging in.

While the Birko-Flor® upper can tolerate some moisture, the cork footbed can be damaged by prolonged exposure to water. It's best to avoid wearing them in wet conditions like swimming or heavy rain.

The break-in period varies per individual but usually takes a few days to a couple of weeks of intermittent wear for the footbed to fully conform to your foot's unique shape.

The Arizona style offers a regular fit. The adjustable straps provide some flexibility, but individuals with significantly wide feet might find them snug.

Clean the cork footbed gently with a damp cloth and mild soap if needed. Avoid soaking it in water. Allow it to air dry naturally away from heat sources.

Adjust the buckle on each strap to achieve a secure and comfortable fit for your foot.

Wear the sandals for short periods initially to allow the footbed to break in and conform to the shape of your foot.

Ensure you are using a mild soap and only a slightly damp cloth. Always air dry away from direct heat or sunlight.
