Each pair of Nike's Flyknit Roshe Run 'Random Yarn' is distinctively one-of-a-kind, attributable to its innovative construction utilizing surplus yarn from the production of other Flyknit models, thus minimizing waste. While the vibrant coloring on the knit upper ensures its uniqueness, every shoe shares identical features such as a white Swoosh, white sole unit, and black laces and trim, maintaining a consistent and classic design.
