The National Trust is a great British organisation. It is dedicated to preserving the heritage of Britain. I always love visiting some of the beautiful stately homes and country gardens preserved by the National Trust.
One of the rules of the National Trust, is that if you visit one of their country houses and you are wearing heels smaller than a postage stamp, you will be given plastic slippers to wear inside. Alternative slippers can be purchased to wear instead if you want. This rule is meant to protect the floors of their properties.
Of couse, I doubt that many women would visit a country estate wearing stiletto heels.
Your home may not be as old or valuable as a National Trust-preserved Georgian house, but high heeled shoes may cause damage to marble floors, wood floors, laminate floors and carpets. Time to put those slippers on.
