The workhorse with wings undertakes a new evolution, becoming quietly unlike any Pegasus to come before it. The Nike Air Zoom Pegasus 41 sports a softer, springier and all-over more responsive running sensation. ReactX foam appears in the model for the first time, the softer foam, helps to extract more energy and pop from the Air Zoom units in the forefoot and heel. This cushioning overhaul is paired with enhanced upper materials to help elevate the overall experience and propel the running world forwards.
