Li Ning Blackball

In an effort to find every advantage to our sprinter Asafa Powell, I came up with the idea of increasing Asafa’s mechanical advantage by extending the ‘lever’ of his track spike plate. The toe was extended slightly so that with each toe off he was exerting more propulsion force. We made prototypes but never tested with Asafa as I left Li Ning shortly after. The goal was to create a shoe that would be outlawed by IAAF.
