The Endorphin Speed 4 is our premium fast and light hybrid with the ultimate blend of lightweight responsiveness, ideal for those who prefer a neutral daily trainer, faster workout days or race days of any distance.
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.
