All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His slave and Messenger.
If you were resolved and indented to do what you had sworn to do in your oath, it is considered a binding and not a meaningless oath and it does not expire by the passage of time.
Since the act that you swore to do in your oath is impermissible, as it involves transgressing against others' property and disposing of it without his permission, you should offer expiation for breaking your oath, given that your oath is considered broken if you did not do what you sworn to do when your wife does the act about which you took the oath. However, as long as your wife is cleaning your shoes (fulfilling your oath), your oath is not considered broken.
Allaah Knows best.
