Our Verdict
ASICS NOVABLAST 5
Nike Pegasus 42
The ASICS NOVABLAST 5 is a better shoe than the Nike Pegasus 42. It's lighter, much more cushioned, and bouncier, making it the pick for runners who want one shoe for daily training, long runs, and faster workouts. The Pegasus 42 is firmer and more stable, with a more rockered heel, so it's still a solid choice for heel strikers who want a steadier, more grounded ride.
