Nike Zoom Fly 6 First Run Review: A Return to the Super Trainer Fight

Introduction

The Zoom Fly line has had a long and uneven history. The earliest versions were excellent fast training shoes that worked hand in hand with a carbon plate racer, but later models grew heavy and bulky and drifted into being plate-equipped daily trainers that lacked excitement. The Zoom Fly 5 was a particular low point, and the shoe had fallen well behind a competitive super trainer market that now includes the Hoka Mach X2, New Balance SC Trainer, Saucony Endorphin Speed 4, and Puma Deviate Nitro alongside others.

The Zoom Fly 6 looks designed to rejoin that conversation. The key changes are simple: it is lighter, bouncier, and faster than its predecessor. Pricing sits at £155 or $170, which is broadly in line with other super trainers, and weight has dropped to 266g (9.4oz), a significant cut from the Zoom Fly 5, which weighed over 300g even in its lighter sizing.

A Return to Form for the Zoom Fly Line

Nike has rebuilt the shoe around a more convincing super trainer recipe. Stack height is now 42mm at the heel and 34mm at the forefoot, for an 8mm drop. The design combines a two-layer woven mesh upper, a two-layer midsole with fresh ZoomX foam over an SR-02 base, a full-length carbon Flyplate, and a rubber outsole covering the forefoot with two patches at the rear, leaving exposed midsole foam in the classic fast-trainer setup.

The result is a shoe that aims to be comfortable enough for daily miles while still having genuine pace in reserve, rather than the bulky compromise the line had become.

Fit and Comfort

Fit is one of the strongest parts of the Zoom Fly 6. A long first session of roughly 27 to 28 kilometres straight out of the box produced no discomfort at all. The two-layer woven mesh upper is comfort-focused, with generous padding around the heel and tongue and an internal heel counter that cradles the foot without irritating the achilles.

The toe box is slightly more dialed in than some rivals, so runners who are broad for their size may find the forefoot a touch tight. Sizing is straightforward: stick to your normal Nike size, though the shoe might run a fraction shorter than some other Nike models in the same size.

Midsole: ZoomX Over SR-02 With a Full Carbon Plate

The midsole is where the biggest changes live. The top layer is now fresh ZoomX foam rather than the recycled ZoomX used in the Zoom Fly 5, and the balance between the two layers has shifted toward more ZoomX. Between them sits a full-length carbon Flyplate, similar to the setup in the Alphafly and Vaporfly, though with slightly more flex. It remains a stiff shoe, as expected from a plated trainer, but the added give makes it more forgiving.

The SR-02 lower layer provides a stable base rather than a huge amount of squish and spring. The outsole rubber covers the forefoot with two patches at the rear, leaving the SR-02 exposed in the midfoot, which should hold up reasonably in durability terms.

How It Performed at Speed

Tested in a demanding track session of ten one-mile reps with progressive paces from 5:30 per mile down to an all-out final rep, the shoe stayed on the feet for the entire workout. From about half marathon pace and slightly slower, the Zoom Fly 6 felt genuinely quick: stable at speed, with a natural ride and enough punch to turn the legs over comfortably, even running slightly faster than target pace.

It is not a super shoe ride. There is no dramatic sink-and-bounce sensation, and for a flat-out all-out rep the shoe felt a little too controlled compared with a true carbon racer. But for the kind of session a super trainer is built for, sustained pace just under race effort, it delivered exactly what it should.

Who Should Buy the Zoom Fly 6

This is now a comfortable, versatile plated trainer that can hoover up easy miles at 8-minute-mile pace and then handle half-marathon-pace reps in the same run. It leans toward comfort rather than race-day spark, sitting closer to shoes like the New Balance SC Trainer v3 in character. Runners who found previous Zoom Fly models heavy and dull will find this a major step forward.

Early Verdict

The Zoom Fly 6 ticks the boxes the line has missed for several generations. It is much faster, lighter, and more versatile than the Zoom Fly 5 while keeping a strong emphasis on comfort, and it evokes the Tempo Next% in the way its foams work together to provide a bouncy, understated but responsive ride.

For runners seeking a plated super trainer that can handle warm-ups, long runs, and quality sessions without needing a shoe swap, the Zoom Fly 6 makes a compelling case. A full verdict after more miles will follow, but on first impressions this is a shoe you can genuinely use every day.

Conclusion

The Nike Zoom Fly 6 marks a confident return to form for the line. It costs £155 or $170, weighs 266g, and delivers a comfortable upper, a fresh ZoomX and SR-02 midsole with a full carbon plate, and enough speed to anchor serious training sessions. If you have been disappointed by recent Zoom Fly models, this is the version worth another look.
