According to respected Japanese scientists, I.M.Watchinu, the Global Positioning System (GPS) technology now found in phones and watches is "flawed". The problem being, in Watchinu's mind, is that mobile phones and watches can be easily left at home (intentionally or otherwise), and you don't know where your wife's got to while you're busy in the office, or where your kid's gone after dark.
This is what inspired Watchinu to develop GPS in shoes: "You can't leave your foot apparel behind. It came to me one night while I paced the floors wondering where my teen son and my very sexy wife were. By morning, I had developed the GPSS-twe Global Positioning System Sneaker. Now I sleep like a baby. If I get curious where my voluptuous wife is or my rebellious boy, I just go to the computer and i can see where in the world that bitch and little bastard is!"
Inventor Watchinu does admit knowing that his gorgeous wife is in a bar fifty miles away does not really help much: "That's why I'm working on the GPSSC which would include a camera so you could see what the loved one was doing. The bug in the cortaid has been the position of the Global Positioning System Sneaker. What good is a view of the floor! I'm working on a GPSH-it's in the hat, a GPSB-a bra's eye view or the GPST - to see everything the thong sees!"
