Reinvigorate your stride with the Nike Men’s Air Zoom Pegasus 37 Running Shoes. Delivering the same fit and feel that runners love, the shoes have an all-new forefoot cushioning unit and foam for maximum responsiveness. Nike React foam at the midsole is lightweight, springy and durable. More foam means better cushioning without the bulk. An Air Zoom unit at the forefoot is twice as large as previous versions, delivering more bounce with every step.
