They've been about for a while now. It all started a couple of years ago when that research into how expensive/fancy trainers were actually not as good for athletes as bog standard "normal" ones. And that progressed into bare footed is even more beneficial / less injury prone. With that said I admit that I also remember seeing ads for a barefoot style "shoe" too. So you could well be right. (as it stands I recall the science and research was pretty solid - especially the stuff about cheap trainers over expensive ones)
