MIAMI -

Nike is selling LeBron James' newest sneaker for over $300.

According the Wall Street Journal, LeBron's next shoe, the "LeBron X" will cost around $315.

The shoe debuted at the 2012 Olympic gold-medal game between Spain and the United States.

This will be LeBron's 10th shoe release.

His first shoe was released in 2003.

It was called the Nike Zoom Generation and cost around $110.

Nike told the Journal that it is passing along price increases because of the increased cost of materials like cotton.
