Your favorite neutral Nike runner is back and better than ever! The Men's Nike Air Zoom Pegasus 34 Running Shoes feature an engineered mesh upper for lightweight ventilation. Dynamic Fit technology delivers a one-to-one personalized fit. Responsive cushioning is at a premium thanks to the springy and supportive premium Cushlon ST midsole. Rubber crash rails on the lateral outsole act as another cushioning device for soft, smooth transitions. Waffle pistons in the rubber outsole help absorb impact and allow for multi-surface traction.
