"The NFL’s Adrian Peterson, Larry Fitzgerald and Troy Polamalu, the NBA’s Brandon Roy and Amar’e Stoudemire, and Olympic decathlon gold medalist Bryan Clay all appeared as part of the media event in Southern California. Even Jackson showed up in videos discussing the shoe that was so much a part of his legacy.

Three NFL All-Pros, two NBA All-Stars and an Olympic gold medalist were out in force Thursday for the U.S. media launch of the Nike Trainer 1.

It was justified. The shoe has quite a legacy to live up to.

The original Nike Air Trainer was adopted and unexpectedly worn in competition by tennis great John McEnroe. It was the impetus behind the brand-elevating "Bo Knows" campaign starring two-sport star Bo Jackson. And it ignited Nike cross training.

Some 20 years later, advances in how athletes train and how shoes are made created the right moment for the Nike Trainer 1, available to consumers in the U.S. on July 1."
