Nike continues to experiment with hybrids, combining different styles of shoes and technology, and this Nike Air Zoom Tennis Trainer is no different. It is a combination of the Nike Air Trainer 1 and Nike Air Trainer 2, with a Nike Free inspired midsole, and a training outsole. The tongue of the shoe features John McEnroe, one of Tennis’ all time greats. He is notorious for bringing the “Trainer” to the courts. The particular colorway shown above is inspired by the Nike Air Trainer 1 - Chlorophyll and is expected to release sometime in Fall 2008. They will retail for $80.
