Usually after the great success of a shoe that becomes an instant classic, people are so captivated by the original model that even thinking about another version is reaching. With the exception of signature shoes or general models, it's never a given that a shoe will take another form, but Nike has decided to expound on one such model that is bound to generate another level of fanfare.
The Nike Flyknit One V2 is that very shoe and has come alive in its 'Version 2' classification. Still utilizing its full Flyknit upper, the V2 takes on a new pattern, giving more lateral support in its knit pattern and defining the Flywire portals in a bolder fashion. Lunar Foam (or Lunarlon) still plays a huge part in the V2, serves the main carrier of cushioning (that's currently known for the shoe), but with a new pattern, particularly in the heel. Toned zones mark the V2's outsole, hinting at what is probably visual research data that has become the shoe's new outsole traction pattern.
Little else is known about the Flyknit One V2, but look for a Spring 2014 release, so you may want to plan for a new runner when the seasons change.
