Nike Unfree
NikeFree is now on its 7th version of its "free" shoe, which is supposed to be like running barefoot. However, as the versions have progressed, the freedom was suppressed! For example, version 7.0 no longer has a flexible inner arch, most likely to provide more support. Additionally, the heels of each version have progressively gotten higher and higher (i.e. more cushioned). This shoe is pretty much the same as any other Nike shoe.
Though, Nike's 1st version of Nikefree was a far cry from running barefoot, at least it was completely flexible in every direction.
IN SUMMARY: if you want to run barefoot, but feel like you need something around your foot (cold climate, broken glass, etc), I would recommend using Aquasocks. You will save $70.00 and as along as you don't buy them at WalMart, you also won't be supporting sweatshops!
