642198 NIKE FREE 5.0 '14 ($100)
631053 NIKE FREE 4.0 FLYKNIT ($125)
I'm not too sold on the upper of these yet, but I'm curious to see how Nike improved the Free outsole. From the pictures posted so far, the bottom of the shoe looks much thinner than the current 5.0 model. They actually look more like a 3.0. Oh, and hopefully the 4.0 Flyknits don't disappoint. For $125, they're the cheapest Flyknit shoe yet.
Pic of the 4.0s over here - they look promising.
