In this Nike Pegasus 41 you will find a comfortable all-round running shoe that is specially made for children. This versatile shoe is designed for energetic children's feet and can be worn anywhere where you can run, jump or play. Midsole The midsole of this shoe is made of ReactX foam. ReactX is a lightweight, firm foam for a smooth, responsive ride with much less impact. With 13% more energy return and 43% less carbon emissions than regular React foam. The midsole of this shoe has a Zoom Air unit that absorbs shock and bounces back quickly, reducing the stress on muscles, joints and tendons. Zoom Air units ensure a faster, more efficient transfer of energy, so you can jump higher and run faster. Upper The mesh upper is not only highly breathable, but also provides a comfortable running experience. Outsole The shoe's rubber outsole provides good grip and traction while running. The forefoot has extra flexibility due to the flex grooves in the outsole and this ensures a smooth way of walking. This shoe has Nike's characteristic waffle pattern as an outsole, with short rubber studs in the shape of honeycombs, for grip on wet and dry surfaces.
