Three innovative technologies power your run: A double dose of Air Zoom units helps launch you into your next step; a full-length carbon fiber plate helps propel you forward with ease; and a heel-to-toe ZoomX foam midsole helps keep you fresh as you conquer the iconic ekiden.

Fuel the Fire
This edition draws color inspiration from the Japanese flag, ready to usher in the next centennial of this New Year's relay race.
Energy Return for the Ekiden
Two forefoot Air Zoom units combine with ZoomX foam to store and return the energy back to you, powering every step.
Fire Underfoot
A full-length carbon fiber plate delivers a propulsive sensation that helps you smoothly transition through every stride and tackle turns with confidence.
