Faithful, reliable, and revolutionary, the Nike Air Zoom Pegasus 41 is unlike any other Peg that has ever been made before. Built with the same internal materials and padding as its predecessor, these running silhouettes are here to push the running world forward while still putting your wants and needs on top of the priority list. The two Zoom Air units combined with the Nike ReactX foam promise you a bouncy, springy sensation and an energized feel at toe-off. Whether you're logging long marathon miles, squeezing in a speed session before the sun goes down, or hopping into a spontaneous group jaunt, you can put your faith in the Nike Air Zoom Pegasus 41, day after day, run after run. Nike Air Zoom Pegasus 41 features: Engineered mesh upper creates an inviting feel and fit. Broadened forefoot and heel width leave space for the springy Zoom Air engine to deliver a cushioned ride. Implemented midfoot band offers a more secure but forgiving sensation. Midfoot strap provides a molded fit that is shaped for all-sized arches. Nike ReactX foam is engineered to reduce its carbon footprint by at least 43% and adds a sustainable touch.
