LeBron James to debut 'chalk' shoe (AP)

To launch his newest sneaker, LeBron James and 20,000 fans will turn Quicken Loans Arena into an indoor winter wonderland. When the Cleveland Cavaliers face the Washington Wizards on Christmas night, James will be wearing a "chalk" version of his signature Nike shoe, a tribute to his pregame ritual of tossing and blowing hand rosin into the air above the scorer's table before he takes the court.
