ULTRA - Just when they think you couldn"t get any faster _ you do. With its fully reengineered, lightweight ULTRAWEAVE upper, the new ULTRA ULTIMATE takes its signature speed and acceleration to the next level. The application of PWRTAPE draws from the anatomy of the human foot to provide natural support for quick changes of pace and direction. At least 20 of the upper is made of recycled materials as a step towards a better future.
