'Shoe' in the Bible

then his brother’s widow shall approach him in the presence of the elders, and pull his sandal off his foot and spit in his face; and she shall answer and say, ‘So it is done to that man who does not build up his brother’s household.’

In Israel his [family] name shall be, ‘The house of him whose sandal was removed.’

“Moab is My washbowl;Over Edom I shall throw My shoe [in triumph];Over Philistia I raise the shout [of victory].”

“Moab is My washbowl;Over Edom I will throw My shoe [to show Edom is Mine];Over Philistia I will shout [in triumph].”
