Slimmed down and more breathable than ever, Nike's Air Zoom Pegasus 36 Running Shoe is back again and ready for hot summer runs. It's got a new slimmer heel collar and tongue to reduce bulk and keep you light on your feet, while a full-length Zoom Air unit ensures an ultra smooth and responsive ride on the road. You've got Flywire lace cables that hug the midfoot for a snug, comfortable, and supportive fit for your speedier track sessions, as well as a grooved outsole construction that ensures a smooth and stable transition through your gait. Key to this update is an engineered mesh upper that features more perforations for greater breathability as you pick up speed and start to sweat, which also delivers targeted performance in high-heat areas to keep you the most cool where it's most important.
