The Nike Zoom Pegasus Turbo 2 is updated with a featherlight upper, while innovative foam brings revolutionary responsiveness to your long distance training. The rubber outsole helps absorb impact and provide multi-surface traction. An angled heel optimizes initial touchdown and provides a smooth transition. An ultralight Nike ZoomX midsole delivers Nike Running’s greatest energy return yet. Additional foam provides lightweight cushioning with every step. The engineered heel collar tapers away from foot for comfort around your Achilles tendon. The lofted mesh and synthetic upper is lighter than its predecessor, while looking as breathable as it feels.
