For wanderers and caregivers – another long-awaited device. Beware of pre-announcements. So GTX has announced that the long-awaited GPS shoe (let's call that 'footware') will be available in October (that’s now!) for $299, enabling a geo-fence to be set for the wearer, alerting when the shoe travels outside of the specified area. From the NY Times article, the argument for the GPS shoe came from Andrew Carle, the coiner of ‘Nana technology’ and a professor at George Mason University. He suggested the idea to Aetrex, the shoe manufacturer, which first announced that it was going to begin product testing in 2009. I got pretty excited by that in 2009, but after placing a call every six months to learn that it was not available, I gave up.
