Global Trek Xploration Corporation develops "GPS Footwear” to track loved ones.

These GTX GPS Xplorer Smart Shoes will let you keep track of your children, novice marathoners or your scavenger hunt team, wherever they roam.

The Xplorer Smart Shoe allows you locate the wearer of the shoes. Like many GPS locator devices, you are able to define a "safe" zone that sends an alert when the boundary line is crossed. For example, you can create a safe zone around a school or neighborhood where you feel safe for your children. When the child wanders outside of the safe zone, an SMS alert will be sent to your phone. This finder device allows for piece of mind while minimizing the risk of the device being lost. These shoes can stay charged for several days for an extended feeling of security.
