A fast, speedy, and supportive shoe? That's just plain fun. So we used lightweight materials, propulsive design, and our trusted GuideRails® support for shoes that are fast enough for race day but durable enough for everyday runs.

• We've added more BioMoGo DNA cushioning for a dynamically responsive ride.

• Midsole stack height increased by 2mm to provide more responsiveness.

• BioMoGo DNA foam cushioning adapts to your unique gait, weight, and stride to deflect impact away from your body.

• Our cushioning technologies all start with DNA because they react to your unique stride.

• Our innovative technology supports your body in its natural motion path while keeping excess movement in check

• GuideRails® support aids your feet, knees, and hips.

• Redesigned midsole and Green Rubber Outsole help your foot move quickly from heel to toe.

• Green Rubber earned its name because it's made out of silica instead of petroleum, making it a more sustainable material choice.
