Originally designed for Ronaldo in’98, Nike’s fastest football boot gets made over for everyday wear in the Nike Zoom Mercurial Flyknit Men’s Shoe. Benefits Flyknit upper for a dynamic fit Lightweight foam midsole with Nike Zoom Air for cushioning Durable rubber outsole provides traction Ankle support for stability Flyknit Origins Nike Flyknit technology was inspired by feedback from runners craving a shoe with the snug (and virtually unnoticed) fit of a sock. Nike embarked on a four-year mission with teams of programmers, engineers and designers to create the technology needed to make the knit upper with static properties for structure and durability. Then the precise placement of support, flexibility and breathability-all in one layer-was refined. The result is a featherweight, formfitting and virtually seamless upper.
