The Nike Free RN Flyknit 2018 'Triple White' sneaker is another bold addition to the Free RN lineup. Created with a runner’s performance in mind, the Free RN takes its inspiration of the Flyknit Racer a step further with vents on the sides of its upper. Its Flywire cables reinforce the design and integrate into the shoe's spandex laces. Additional support from the Dynamic heel and foam-cushioned sole allow promote comfort and range of motion.
