The Birkibuc material is water-resistant to a degree, but the footbed (cork-latex) is not waterproof and can be damaged by prolonged exposure to moisture. They are best worn in dry or mildly damp conditions.

It is not recommended to wear these sandals in the shower or pool. Excessive water can degrade the cork footbed and affect the adhesive, leading to premature wear.
