The legendary runner returns, delivering the same beloved fit with re-tuned cushioning for an even funner, more energetic running experience. The Nike Air Zoom Pegasus 37 Running Shoes integrate React foam into the midsole for more responsive, longer lasting cushioning. The Nike Zoom Air unit in the forefoot is twice as large as the previous model and placed closer to the foot for more bounce with every stride you make. Reinvigorate your run with the newest edition of the Nike Zoom Pegasus.
