The Nike Wmns Free RN Flyknit 2017 'Blue Tint' was released in July 2017 for women's specific, lightweight running performance. Up top, an ultra-breathable, sock-like Flyknit upper keeps the foot cool and dry and enlists Flywire cables and quick-lace system for a distraction-free run. A responsive midsole works with a flex-grooved outsole below for a truly resilient stride. Nike branding accents the tongue in black and comes in the form of a Swoosh insignia at the midfoot.
