I want to take the
I want to take the fundamentalist position here and say that no covering of the sole can ever be described as barefoot. Then again, maybe we've gotten to the point where we need to either throw a ton of money at the problem and really tell people how it should be or just accept the state of things. Once barefoot running isn't such a novelty I expect we'll see a more tempered debate and more people will realize the difference between shoes and barefoot. Until then, maybe "barefoot inspired" can be a good compromise?
Let's face it, if barefoot running stops being controversial then we're only at the beginning of the process and if it's a fad that will die out, it will die in a few years' time. Either way, I think the word barefoot will stop being abused like it is right now when everyone wants to get in on Vibram's profits. Marketers will find another word to mangle in time, they always do, and once that happens we might stand a chance of getting things back on track.
