The Nike Zoom Fly offers an updated take on Nike's Breaking 2 running shoe—used in the attempt to run a marathon in fewer than two hours. This 'Barely Grey' version comes in a seamless one-piece Flyknit upper in white, with platinum accents and a black Swoosh and black piping that ties the look together. The shoe employs a full-carbon plate and energy-returning Lunarlon foam to help propel runners with every step.
