This indicates a children's size, specifically a UK 13 for younger children. It is generally smaller than an adult size 1 and is often equivalent to a US children's size 1. It's recommended to measure your child's foot to confirm the best fit.

No, the materials used, particularly the leather lining and cork footbed, are not waterproof. While they can handle light moisture, they should not be submerged in water.

The rivet details can be wiped clean with a slightly damp cloth along with the rest of the upper material. Avoid using abrasive cleaners that could scratch the finish.

While designed to be worn barefoot, some individuals prefer to wear thin socks with them. However, wearing socks might alter the fit and how the footbed contours to the foot over time.

Birkenstock typically offers a warranty against manufacturing defects. Specific warranty details can vary by retailer and region, so it's best to check with the point of purchase for exact terms.

Yes, the core of the Birkenstock footbed is made of natural cork, which is known for its cushioning and support properties. The description mentions 'Other Materials' for the upper and sole, but the characteristic Birkenstock footbed is present.

There should be a small gap at the heel and toe when the child is standing. The straps should allow for a snug fit without pinching. Comparing to your child's current well-fitting shoe size or using a Br kenstock size chart can be helpful.

The footbed may require a break-in period. Wear the sandals for short periods initially and gradually increase wear time. The cork footbed will mold to the shape of your child's foot.

Adjust the buckle on each strap to find the most secure and comfortable fit for your child's foot width.

This can occasionally happen due to friction between materials or moisture. Try applying a small amount of talcum powder under the insole or around the straps. Ensure the sandals are completely dry.
