Positioned as an endurance racer, the Carbon X-SPE delivers the same propulsive speed as its predecessor in a street-ready silhouette. Engineered with a responsive, carbon fiber plate and aggressive Meta-Rocker, this performance shoe is a formidable competitor. Created in limited run, the Carbon X-SPE sports a tongue-free upper encased in a soft, mesh bootie and lined in a thin, mono-mesh that hugs the forefoot. Featuring a unique combination of foams, this special edition style delivers an inherently soft, stable and responsive ride.
