Our Verdict
Nike Pegasus 42
Nike Winflo 12
The Nike Winflo 12 is a better shoe than the Nike Pegasus 42 for most runners. It's much better cushioned, more stable, and significantly more energetic underfoot, making it better suited to daily training and longer runs. The Pegasus 42 is lighter and has a lower-profile build with more feedback from the road, so it's the better pick if you specifically prefer a firmer, more grounded ride.
