I'd be interested if any HN members consider James Stanley a 'cyborg' with the shoes on?

From what I've found on Wikipedia, it sounds like wearing the shoes is an, "integration of some artificial component or technology that relies on some sort of feedback."

This got me thinking that the Nike shoes Marty wore in Back to the Future 2 could also be considered a cybernetics enhancement.

To what degree does a device need to be integrated with a human body for that human not to be considered a human any more?
