Move over Maxwell Smart, an Australian computer scientist has developed a real-life version of a shoe phone complete with step-by-step instructions online according to the Sydney Morning Herald.
Its inventor insists there are practical applications - including, surprisingly enough, helping the elderly.
Paul Gardner-Stephen says the gadget has been so popular among the geek crowd that he is considering selling it through online stores.
The shoe could hold equipment used to store and communicate pulse, blood pressure, blood oxygenation and other information.
It could also be used in nursing homes whereby the shoe could detect a fall and automatically place a call to a medical carer over a speaker phone.
