A prolific winner and record-setter at every level, Cristiano Ronaldo is an obvious exception. From his first pro contract at age 10 to multiple Player of the Year honors, he's dominated the world's biggest stages with speed, savvy and a scorer's touch. FLYKNIT ORIGINS Nike Flyknit technology was inspired by feedback from runners seeking 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.
