One of the most trusted running shoes in the Nike line, the Air Zoom Pegasus 34 is back with a snug, one-to-one fit and improved traction. The Pegasus 34 appeals to a wide range of runners at all levels because of it's supportive fit, neutral cushioning, and fast feel. This experience starts with the shoe's upper, which is constructed from Nike's Flymesh material, a dual-layer system of monofilament yarns that delivers lightweight strength and an ultra-breathable feel, so you stay fast and fresh even on your longest run. Zoom Air units in the heel and forefoot work together with soft Cushlon ST foam to provide the perfect combination of comfort and response, absorbing impact and keeping you light on your feet. The finished product is a dependable running shoe with the versatility to tackle any workout.
