Birkenstock Boston Slippers & Sandals - Grey - 4

Yes, they generally follow standard sizing, but because they are unisex in design, we recommend checking your specific UK size to ensure the length provides enough space for your toes.

It is not recommended. Suede is a natural material that can be damaged by excess water and the cork footbed should stay dry to maintain its longevity.

Your toes should have a small amount of space in front of them, and your heel should rest comfortably in the deep heel cup without hitting the back rim.

While the footbed is designed to last a long time, authorized Birkenstock repair shops can refurbish or replace footbeds if they eventually wear out.

Yes, the Boston is frequently worn with socks, which is a popular look that also adds warmth and keeps the footbed cleaner for longer.

This is normal. Wear the shoes for short periods daily until the cork-latex compresses and conforms to your foot anatomy.

Use a specialized suede brush or a crepe brush to gently lift the nap of the leather and restore its soft appearance.

Check the strap holes for signs of wear. If the buckle continues to slip, ensure it is fully engaged in the desired hole before walking.
