A tip-of-the-spear product geared for elite runners, the Rocket X 2 has been amplified with a hyper-focus on construction. Weve remastered the geometry of our propulsive carbon fiber plate, sandwiching it between two layers of a brand-new, ultra-responsive, high-performance foam. Employing a technical synthetic mesh upper for a foot-hugging fit, this front-of-the-pack shoe enlists a sleek gusset and internal midfoot cage for race-ready lockdown.
