Usain bolt product placement?

Question

After he won he took off his shoes and waved them, and posed next to the timer board with his shoe in a hand. Isn't it illegal for an Olympic athlete to advertise commercially?

Answer 1

Could you tell what brand he was wearing ?? I don't think you could. And neither could I.

Answer 2

He reminded me of Micheal Johnson he did a similar thing with his shoes when he won his gold.
