Nike's latest innovation is one that they'll be hoping makes history.

Last year, Nike and a group of elite marathon runners set out to put their names in the history books by running a marathon in under two hours for the first time ever. 2016 Olympic gold medallist Eliud Kipchoge came closest, running the 26.2 miles in 2:00:25.

The Kenyan was 25 seconds away from immortality. The slimmest of margins. Knowing that sport is all about marginal gains, Nike went back to the drawing board to find the latest innovation that could push Eliud ever closer to the 120 minute mark. The Nike Zoom Vaporfly Elite Flyprint is the result.

The new running shoe features the first ever 3D-printed upper in performance footwear, shaving six per cent of the weight from the shoes that Eliud wore last year. The development is the first sign that 3D printing has the potential to push sportswear further and faster than has ever previously been possible.

We caught up with Senior Footwear Director at Nike Running, Brett Schoolmeester, to get the inside track on the Nike Zoom Vaporfly Elite Flyprint.
