WHY YOU'LL LOVE IT

 

• Speedroll technology featuring a nylon plate but modified for more rigidity and support in the midfoot. The nylon plate is more versatile to accommodate a greater range of speeds and paces. • PWRRUN PB foam is a unique beaded formulation of a peba foam which is both more durable and consistent resulting in a responsive and bouncy feel mile after mile. • Lattice inspired outsole design with XT-900 carbon rubber for lightweight durability without sacrificing traction. • Zonally engineered mesh is both breathable and supportive.
