Launched in 1998, the Nike Mercurial soccer cleat was inspired by Cristiano Ronaldo to deliver a lighter, faster boot to the pitch. Released in January 2017, the Nike Zoom Mercurial XI Flyknit shoe captures the style elements of the 90s turf classic and re-conceptualizes it for the street. Its adaptive, Flyknit upper is supported by a bootie-like construction, Phylon midsole, Zoom Air cushioning, and rubber outsole.
