Nike designers had a clear focus when creating Charles Barkley's signature shoe - ensuring constant lockdown. Their determination to achieve this goal resulted in designing support straps inspired by straitjackets, which securely wrap around the upper. To further enhance stability, they incorporated a reinforced lace-lock system that was also featured in the Air Max Uptempo. Recently, in April 2015, a patriotic-themed makeover was given to the shoe, featuring an Obsidian nubuck upper with striking white and red accents.
