The Nike Air Zoom Pegasus 37 'Black Dark Grey' is a performance running shoe that is perfect for everyday training with its monochromatic design. The upper of the shoe is made of a one-piece textile material that not only provides breathability but also includes mesh detailing for enhanced airflow. To ensure a snug and personalized fit, the shoe features a midfoot band that adapts to the wearer's foot. The midsole of the shoe boasts a responsive React foam that offers excellent cushioning, and it also houses a top-loaded Zoom Air unit in the forefoot, which is larger than in previous Pegasus models, providing even more impact absorption and energy return. The shoe is completed with a reliable waffle outsole that delivers excellent traction on various surfaces.
