A new cushioning system that uses Helion HF foam and expands in all directions for next-level comfort and energy return – built for the demands of marathon racing.
The open-weave upper offers lightweight support and breathability, helping heat and moisture escape – so your feet stay cooler, drier, and more comfortable through every mile until the finish line.
A lighter, more resilient Helion HF foam, stiffer carbon Speedboard, and high-traction carbon nanotube rubber combine for efficient propulsion and performance.
