The Shadow 5000. The modern classic returns with a premium update of its sporty past. Originally released in 1989 as a performance runner, the shoe represents a period of genuine innovation in running technology where athletics met aesthetics. Now, 30 years later, the Shadow 5000 has transcended its sporting roots and evolved into a modern classic. A shock-absorbing EVA midsole brings the comfort of these shoes to the next level while a XT-600 triangular lug rubber sole gives them excellent grip.
