With the launch of the sixth generation Lebron James signature Nike shoe, the Nike Zoom Lebron VI, only a few days away, Nike has released a new commercial to coincide with the shoe. The commercial entitled “Chalk” features a number of different people throwing chalk in the air much like Lebron does prior to tip-off every game. An interesting commercial to say the least but like many Lebron commercials before this, we must say Nike has done another great job.
