This updated iteration of the Ultra Boost is simply made with Primeblue, a high-performance recycled material made in part with Parley Ocean Plastic. It’s worth noting that 50% of the upper is textile, while 75% of the textile is Primeblue yarn. Finally, the pristine profile is further detailed with a translucent lace cage and heel counter, followed by an elevated Boost midsole to round out its design.
