At the 1996 olympics Johnson famously won two gold medals wearing golden Nike track spikes, following this, he famously adopted the nickname 'The Man In The Golden Shoes'. After his olympic success, Nike and Johnson released a signature track spike, the JSC and an off-track model, the JST. The latter featured a synthetic leather and breathable mesh upper, a Phylon midsole with full length internal Zoom Air and Michael Johnsons signature embroidered in gold. This technology provided the responsiveness of a spike, with the cushioning and support to handle the rigors of training.
