Nike’s Air Max technology has come a long way since 1987. What started as a visible air unit in the heel eventually turned into a full-length sole. Air Max is going to another level next year with the VaporMax, a running sneaker that represents the apex of Nike’s proprietary tech. Not only is this new innovation catered to flex with the natural motion of your foot, it also fulfills the promise of actually running on air without any foam or other layers in between. It isn’t set to launch until the spring of 2017, but Nike’s VP of Innovation Seana Hannah broke down how the brand made this product possible.
