Whether you run short or long distances, the Nike Air Zoom Pegasus 41 EK all-round running shoe is designed for your daily run. Experience the ultimate performance of the Air Zoom Pegasus 41 EK every day. Midsole The midsole is made of ReactX foam. Compared to Nike React foam, ReactX is designed to reduce the carbon footprint of a pair of midsoles by at least 43% due to the reduced energy used in the manufacturing process, and to increase energy return by 13%. Zoom Air units are built into the midsole. These absorb shock and bounce back quickly, reducing the stress on your muscles, joints and tendons. You can run faster and jump higher with the Zoom Air Unit because it transfers energy more efficiently. Upper The mesh upper is not only highly breathable, but also provides a comfortable running experience. Outsole The rubber outsole provides the shoe with good grip and traction while running.
