^Nike really thinks it's the most clever company ever made.
Bo Jackson, the two sport phenom in baseball and football, was advertised under a campaign of "BO KNOWS", where they'd show Bo playing every and any sport, to illustrate what a talent he is. It started off as BO KNOWS BASEBALL and then the ads would show him playing soccer or polo and BO KNOWS POLO, stuff like that.
It was gimmicky, it was moderately funny, and it was like 15 years ago. Now, since they recently re-released those ugly trainers, they relaunched the BO KNOWS campaign and just replaced Bo's name with whomever the shoe was a PE for. (LT KNOWS for Tomlinson, etc.). Manny got his own colorway, so he got a shirt with MANNY KNOWS
If it isn't obvious, I think it's a stupid ad campaign and it's more than a decade past any relevance. But I guess people who keep buying shoes they wore when they were 14 might enjoy it
