Built for women who run hard and train harder, the Nike Pegasus 42 is the everyday road running shoe that earns its place in every rotation. A full-length curved Air Zoom unit and ReactX foam midsole work together to deliver a responsive, propulsive ride from heel to toe-off - with ReactX delivering 13% more energy return than previous React technology. The engineered mesh upper is softer and more breathable than earlier iterations, keeping feet comfortable through high-volume training weeks. An updated Waffle outsole with flex grooves and concentrated rubber coverage ensures trustworthy traction on pavement without adding unnecessary weight. Finished in Black with White and Iron Grey details, this women's Nike performance running shoe is a clean, versatile everyday trainer built to go the distance.
