The NBA is prohibiting its players from wearing a new line of sneakers that claims to increase vertical leap.
"Under league rules, players may not wear any shoe during a game that creates an undue competitive advantage," the NBA said in a statement Tuesday.
Athletic Propulsion Labs' $300 Concept 1 shoe employs a spring-based system designed to increase lift.
The Los Angeles-based company was founded by twins Adam and Ryan Goldston, both former USC basketball walk-ons whose father worked in the shoe industry.
