To care for your Classic Unfurgettable Clogs: - Cleaning: For the Croslite™ material, wipe clean with a damp cloth and mild soap. For the faux fur upper and lining (polyester), gently spot clean with a small amount of mild detergent and water. Avoid harsh chemicals or abrasive cleaners. Allow to air dry away from direct heat or sunlight. - Storage: Store in a cool, dry place away from direct sunlight to prevent material degradation. Avoid leaving them in extreme heat (like a hot car), which can cause the Croslite™ material to shrink or warp. - Maintenance: Periodically check Jibbitz™ charms to ensure they are securely fastened.
