NEW YORK (AP) – The NBA is prohibiting its players from wearing a new line of sneakers that claims to increase vertical leap.

The NBA said in a statement Tuesday that “under league rules, players may not wear any shoe during a game that creates an undue competitive advantage.”

Athletic Propulsion Labs’ 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.
