These shoes aren’t made for casual tracking. To limit searches to serious cases, the firm won’t allow spouses or parents to locate relatives unless local police OK the search. To find a person wearing the shoes, a family member has to call Daniel’s monitoring firm, ID Connex, where an operator will notify the police and look for the wanderer. Later this year the firm intends to follow up with shoes that will enable wearers to move the GPS device from one pair to another. And it’s also on the verge of adding cell-phone service to the shoes. In what’s likely to be a disappointment to Maxwell Smart fans, though, the shoe-phones will be Bluetooth-enabled to connect to an earpiece, and you won’t actually get to talk into your shoe. Sorry about that, chief.
