Nike PEGASUS 41 The Nike PEGASUS 41 men's running shoes offer responsive cushioning that provides an energy boost for your daily road runs. Featuring two Air Zoom units and a ReactX foam midsole, these shoes deliver exceptional energy return and a lightweight feel. In addition, the improved special mesh on the upper reduces weight and increases breathability. Designed for both performance and sustainability, ReactX foam minimizes the midsole's carbon footprint by at least 43% compared to previous React foam, thanks to its lower energy consumption during manufacturing. Carbon footprint of ReactX is based on an assessment by PRé Sustainability B.V. and Intertek China on the impact of production right from the start to the finished product. Nike PEGASUS 41
