The ultimate super trainer built for high-mileage performance. The Overdrive ST pairs max-stack cushioning with a responsive dual-foam system: Ethercell™ Pebax® for explosive rebound and Reverb™ EVA for long-haul comfort. Its sculpted StrideFlex Geometry stores and releases energy with every step, delivering a quick-response, propulsive ride—without the need for a plate. Underfoot, the Flowform™ KPU outsole provides lightweight durability and all-weather grip, mile after mile. Engineered for runners chasing both cushioning and speed, the Overdrive ST is where high energy return meets unstoppable durability.
