Whatever your running level, the Nike Air Zoom Pegasus 41 is the ideal neutral all-round shoe. This shoe can handle any pace you run, whether it's a moderate 5K run or a long run. Go for a completely new running experience with this all-round running shoe! Midsole Zoom Air Units are incorporated into the midsole. These absorb shock and bounce back quickly. This puts less strain on your muscles, joints and tendons. You can run faster and jump higher with the Zoom Air Unit because it transfers 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. The Nike Air Zoom Pegasus 41 will help you achieve your goals!
