The Y-3 Adizero Prime x 2 STRUNG Shoes take technical excellence and performance up a notch. They're made with STRUNG, a textile innovation that transforms data into a dynamic material that's adaptive and responsive to feedback. The result is optimised comfort and support, especially during long runs and training aimed at beating personal bests. With a fit that's like a cocoon around the foot, the shoes are made with Lightstrike Pro foam for a superlight midsole that helps increase speed. The STRUNG upper is fused to a Continental™ Rubber outsole packed with carbon ENERGYRODS that push momentum forward to propel performance.
