SoleMates
If you see a single abandoned shoe, you take a picture of it and upload it along with the size, brand, GPS coordinates, and whether it’s a left or a right. The app then finds matching pairs and publishes “Pairing Missions” for users to reunite (reSHOEnite?) the shoes… for donation, perhaps, but also for pure satisfaction.
Secondary usage: if you lose a shoe, upload the info on the remaining shoe and wait for its partner to be found.
