We’ve only seen two colorways of the Nike Air Tech Challenge so far, but now that this new sample model has surfaced online, we can look forward to another third colorway later this year.

This Air Tech Challenge presents a upper made of black leather, suede, and patent leather with hints of mint green on the tougne, toe, and splattered along the sides and heel.  Unlike the past Tech Challenge models, this variation keeps it simple with dark two- tone color scheme which should appeal to just about every Nike Brand fan.

The Black/Mint Nike Air Tech Challenge Hybrid should be releasing sometime later this year (Fall/Winter 2009).
