Pegasus Premium 1 vs Zoom Fly 6

Nike built the Pegasus Premium around bounce, and on that one point reviewers agree it delivers. The full-length Air Zoom unit in its triple-layer midsole gives a springy, trampoline-like ride that most testers enjoyed. The trouble is everything around it. At 308g it's heavy for a super trainer, the fit is narrow, and several reviewers found the tall platform unstable. RunRepeat rated it great and another tester would tell you to try it, but Doctors of Running were far harsher, and one of their testers couldn't run in it at all because the tapered toe box pressed on the big toe.

At £190 RRP that is a lot of compromise. We see it as a fun shoe for easy and steady runs if you're a neutral runner with narrow to medium feet, not a versatile super trainer. If you want Nike bounce in a lighter package, the Zoom Fly 6 is easier to live with, and the Vomero 18 makes more sense for plain easy mileage.

The Nike Zoom Fly 6 is the carbon plate experience for everyone who is not racing. It sits in the super trainer slot: a plated, well cushioned road shoe built to handle tempo work, long runs and the odd race without the price or the fragility of a true marathon flat. At 265g it is no featherweight, and that is the point. Nike has traded the raw speed of its race line for durability and a more forgiving daily ride, so you get the snap of a full length carbon plate stacked on a soft, bouncy midsole that holds up over the miles. If you want the actual race rocket the Vaporfly 4 is lighter and faster, but the Zoom Fly 6 is the one you can train in week after week. We rate it as one of the best value carbon trainers around for runners who want one shoe to cover their faster days.
