Tying shoes on the bumper of a car is symbolic of the power associated with shoes in ancient times. Egyptians would also exchange sandals when goods were exchanged so, when the bride's father gave his daughter to the groom, he would also give the bride's sandals to show that she now belonged to her new husband. In Anglo-Saxon times, the groom would tap the heel of the bride's shoe in order to display his authority over her. The bride would then throw shoes at her bridesmaids to see who would be the next to marry. In Tudor times, it was the custom to throw shoes at the couple or their carriage for good luck.
