Olympic gold-medal-winning American sprinter Allyson Felix is hoping that a collaboration with Nike has produced the perfect set of running shoes to help her repeat her success in 2012. The Nike Zoom Superfly Flyknit is the result of exhaustive scientific analysis from Nike’s Sports Research Lab, computational design from their designers and pixel-level stitch placement from its Flyknit engineers. With the Nike team working closely with Felix and her team of coaches and trainers, the cutting-edge running shoe was fit with a 3D printed spike plate that was precisely developed to Felix’s specifications and biomechanics.
