The Nike Air Zoom Pegasus 38 is a trusted and versatile runner designed for use by everyone from beginners to elite runners. It uses soft, responsive, and lightweight react foam to provide a smooth, durable ride. The Air Zoom unit is placed in the forefoot to maximise its energy return whatever your footstrike. Tuned to the preference of male and female runners, it offers a slightly firmer feel in the men's shoe. The new breathable mesh upper has a plush feel and stretches with your foot for a comfortable fit. The forefoot area is wider allowing improved comfort and a better fit for a broad range of foot shapes. A midfoot webbing locks your foot down at the laces, but extra foam in the tongue ensures your comfort.
