Seamless to set the pace

An ultra-thin, second-skin fit that's seamless, with enough support for race day. How? A single 1.5km long filament is spun by robot to create a mesh-like upper. Which is breathable and elastic, with no need for laces. And, at just 30g, it��s the lightest upper we��ve ever made.

Sprayed to cut emissions

Creating the upper in a single piece not only creates a seamless, distraction-free fit. It also minimizes waste, eliminates the need for glues and emits 75% less CO2 than our other premium uppers. Invented in our lab - for the future.

Power and propulsion

Two layers of Helion? HF hyper foam provide high energy return and impact absorption, with a pre-shaped, stiff carbon fiber Speedboard? sandwiched between, for powerful propulsion at every stride. And, we maximized traction on the outsole, by increasing the ground contact in key areas.
