Though originally made to track patients and kids, we're sure the shoes will be integrated soon with the Nike + Ipod so you can track your run in your personal Google mashup. Or hide it in your wife's purse to see whether she's banging San Francisco's mayor, Gavin Newsom. Or something like that. The system from GTXC has a sophisticated GPS integrated into the shoe, which communicates directly with a satellite, which then relays locations in real-time to their monitoring center and made available via internet or phone. Predetermined geographic areas can also be defined and alerts sent when the person being tracked leaves or enters the area. And don't worry, they already have a product for outdoor activities called the Wearable Caddy. Via Electronista.
