GPS in prostitutes shoes ensure the safety of the modern day sex worker.
Violence is one of the main concerns of this initiative. However, what the Helen of Troy is going to stop a john from smackin’ up a ho. Nada. Zip. However the GPS in their shoe will keep track of these ladies of the night.
I am also concerned that they can only incorporate these into platforms. What if these johns have a foot/shoe fetish? Or if they break their ankle? Each sandal will have an audible alarm system, which emits a piercing noise to scare off attackers.
