After Nike unveiled its Free running collection last week, the Swoosh takes time to commemorate the present and the past with the "Genealogy of Free" pack. Celebrating 10 years of Free technology, the six-sneaker collection includes three classic sneakers that influenced Nike's overall running initiatives, as well as three other sneakers that were actually equipped with the Free midsole. The "Genealogy of Free" Pack consists of the Sock Racer, Air Rift, Air Presto, Free 5.0, Free Run+ 2, and the Free 3.0 Flyknit.

The pack released this past weekend at Dover Street Market Ginza in Tokyo. A U.S. release has not officially been announced, but given the popularity of performance sneakers on and off the track, we're hoping this anniversary collection hits the states.
