Here is some sneaky anti-adultery technology for you. Sayo Isaac Daniel has taken what appears to be a regular everyday pair of shoes and shoved in some GPS trackers so you can always know where they are (and the person attached to them).

I guess these would also be good for people like me who tend to misplace things, but I have yet to lose a pair of shoes (knock on wood). There’s not very much else to these otherwise non-descript foot-coverers. Just boot up the base station and track ‘em down.

Quantum Satellite Technology is perfectly ready to ship these out to you starting in March. The price may come off as a little steep though, as a pair of GPS shoes will run you $350.
