Whether you're training for a marathon or just enjoy a leisurely run, the Nike Air Zoom Pegasus 41 is the ideal all-round running shoe for the neutral runner. This shoe can handle any pace you run, whether it's a moderate 5K run or a long run. Choose versatility and reliability with this all-round running shoe! Midsole A Zoom Air Unit is built into the midsole of this shoe, which absorbs impact and then rebounds quickly, reducing the strain on muscles, joints and tendons. Zoom Air Units allow you to run faster and jump higher because they transfer energy more efficiently. The midsole is made of ReactX foam. Compared to Nike React foam, ReactX is designed to reduce the carbon footprint of a pair of midsoles by at least 43% due to the reduced energy in the manufacturing process, and to increase energy efficiency by 13%. Upper The strap around the midfoot ensures a fit that follows the shape of the foot, for arches of all sizes. Outsole The rubber outsole has Nike's iconic waffle pattern that provides grip on dry and wet surfaces. Flex grooves provide extra flexibility in the forefoot to aid in a smooth walk. Run at your own pace on the Nike Air Zoom Pegasus 41 and push your limits!
