Positioned as an endurance racer, the Carbon X2 delivers the same propulsive speed as its predecessor in an adaptable silhouette geared for training and racing alike. Engineered with a responsive, carbon fiber plate and aggressive Meta-Rocker, this performance shoe is a formidable competitor. The Carbon X2 pairs softer, lighter foam mid-sloe with the same rubberized foam outsole as the original Carbon X. With a focus on fit, the Carbon X2 employs a refined collar shape, notched tongue and engineered mesh upper with embroidered TPU yarns and extra reinforcement around the laces. Get ready for a soft, inherently stable and responsive ride!
