The next logical step in the evolution of Nike footwear along their minimalist track is this just leaked Nike Flyknit Free Hyperfeel. It's clear that this one is going to be both extremely lightweight and incredibly comfortable and responsive; we already know that about the Flyknit upper and the feel of the Free sole. This is about as close to barefoot that you can get without wearing sandals, but then you won't have Nike's Dynamic Flywire system helping you along the way. There's no release date set yet, but it's cool to see the next generation Free sole together with the Knit. A safe bet it would be a Fall/Winter 2013 drop.
