Women's Pegasus 42

Feel the spring of the new Nike Pegasus 42. It's lighter, more responsive and built to keep runners like Nike pro Bailey Hertenstein going day after day for over four decades. The Pegasus has earned its place in more training logs than just about any shoe on the market — and the 42 is the best version yet. A sculpted full-length Air Zoom unit delivers Nike's highest energy return from heel to toe-off, paired with a ReactX foam midsole that's 13% more responsive than previous React technology for an energized, propulsive feel that holds up from mile one to the last. An updated fit gives you more room in the forefoot and toe box so your foot can move naturally, while a softer, more breathable mesh upper keeps things comfortable no matter how long you're out there. Details: Upper: Lightweight engineered mesh is softer and more breathable than previous versions for a comfortable, ventilated fit. An updated geometry provides more space in the forefoot and toe box compared to the Pegasus 41. Midsole: A sculpted full-length Air Zoom unit delivers a propulsive, energized feel from heel to toe-off. ReactX foam — 13% more responsive than previous React technology — adds cushioned energy return for everyday road running. Outsole: Updated Waffle outsole with high-abrasion rubber and flex grooves delivers reliable traction and flexibility on road surfaces.
