This is a specially designed shoe fitted with a GPS chip to track the movement and location of the persons wearing it. The chip is hidden in a separate compartment in the sole of the shoe. The chip is powered by a long-life battery and could be recharged from time to time. The chip emits signals to the wireless tower and subsequently picked up by the satellite, which in turn sends the exact location information of the chip via cyberspace in the home computer. A map is displayed in the computer showing the approximate location of the chip with a coded number within 20-30 yards of the pointer. The shoe is primarily invented to track the missing children and elderly people with Alzheimer. According to U.S. Department of Justice, 797,500 children get missing every year in the United States. The purpose of this invention is to track these missing children by a sophisticated device that never existed before.
