Positioned as an endurance racer, the Carbon X 3 delivers an even more propulsive speed than 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 epitome of long-range weaponry, the Carbon X 3 pairs softer, lighter foam with the same rubberized foam outsole as the last iteration. The Carbon X 3 employs a refined collar shape, notched tongue, and a new engineered knit upper for an improved fit and extra reinforcement around the laces. Get ready for an inherently soft, stable, and responsive ride.

lightweight, and with great tight flat laces

My 3rd pair of X3's and work extremely well for distance, both trail and road. Took me longer than usual to break this pair in; got blisters for the first couple seeks but then became very comfortable with them.

Took 10 seconds off my mile pace. Warning though: took 3 weeks of blisters and band aids before they were broken in. Fit like a glove now.
