The Women's Nike Pegasus 42 Running Shoes are designed to put a spring in your step, delivering the ultimate combination of bouncy comfort and next-level speed for runners. The full-length Air Zoom unit, which is now curved to the shape of your foot, provides the optimal level of springiness underfoot. This responsive unit is perfectly paired with lighter Nike ReactX foam in the midsole, creating a bouncy, energetic sensation that maximizes toe-off performance. The upper locks you in with multi-zoned engineered mesh for secure containment and breathability, while the redesigned, lighter waffle-inspired outsole ensures flexible, reliable traction without adding unnecessary bulk. The Nike Pegasus 42 is crafted to maintain plush comfort mile after mile while unlocking a new, faster version of your run.
