Deuteronomy 25:9
his brother’s widow shall go up to him in the presence of the elders, remove his sandal, spit in his face, and declare, “This is what is done to the man who will not maintain his brother’s line.”
Ruth 4:7, 8
Now in former times in Israel, concerning the redemption or exchange of property, to make any matter legally binding a man would remove his sandal and give it to the other party, and this was a confirmation in Israel. / So the kinsman-redeemer removed his sandal and said to Boaz, “Buy it for yourself.”
