According to gizmag:
With an inbuilt GPS, an audible alarm system and storage for your valuables the Platform 001 sandals could definitely be beneficial in protecting against muggings or to locate ladies in the case of emergency.
Specifically aimed at sex workers the shoes are the brainchild of the Aphrodite Project in response to an ever growing number of attacks against women in the industry. The shoe - aptly named The Platform 001 - was inspired by the prostitutes of ancient Greece and Rome, who enticed clients with their flutes and sandals that left ‘follow me’ footprints in the earth.
And some more features of these shoes:
Functionality of the Platform shoe includes a 3.5 inch LCD monitor with audio and text overlay for promotion to clients whilst safety features include an audible alarm, secure storage compartments and a panic button connected to monitored GPS tracking for use in case of an emergency. The design does raise some safety concerns since they are being promoted as a "safety shoe" with secret storage, potential attackers could become familiar with the design and specifically target those with the shoes thinking them to be carrying valuables. Further, the clumsiness of the shoe could pose a problem in a situation whereby the wearer needed to run at any great speed.
Building a GPS into a shoe seems like a great idea, especially for young children and other vulnerable populations. Having a 3.5 inch LCD monitor built into your shoe is just bizarre to me, but I guess it definitely draws attention to the bling. Who knows, maybe someday we'll all be covered in monitors, from our t-shirts down to our platform shoes.
