Just when you think you can't get any faster, you do. With its fully developed, lightweight Ultraweave upper, the Ultra Ultimate takes its signature speed and acceleration to the next level. The use of Pwrtape is designed according to the anatomy of the human foot, providing natural support during quick pace and direction changes. The dual-density Speedplate makes it official: Ultra is too fast for them. FG/AG: Outsole for firm ground/artificial turf.
