I have always admired the Japanese practice of removing shoes on entering a house and leaving them in the vestibule, usually in a cupboard designed especially for that purpose. I have never, however, seen anybody remove their high heels before entering a church with a cold stone floor. The owner of the red shoes in the photo even took car to place them on newspaper!
