The Adizero Adios Pro series represents the pinnacle of high-end competition shoes: No other shoes have recorded more victories. The Adios Pro 4 promises unprecedented speed and is designed for runners who want to win races and break records. With improved features, the shoe optimizes running efficiency. Its carbon-reinforced ENERGYRODS 2.0 provide a smooth, responsive rolling motion to maximize every step. The new rocker sole design of the midsole offers improved running economy. Two layers of our best and ultra-lightweight foam, LIGHTSTRIKE PRO, guarantee cushioning with each step, regardless of speed – less fatigue, more energy throughout the entire distance. The Continental™ rubber outsole enables slip-resistant grip during push-off and LIGHTTRAXION reduces weight without compromising traction.
