Nike Zoom Fly 6 review: Light, Fast, And Built To Last
The Glam Gods have spoken! A well-priced, lightweight plated trainer blending ZoomX cushioning and responsiveness, ideal for speed training to marathon racing.
I’ve been putting the Nike Zoom Fly 6 through a variety of runs to see how it handles everything from daily miles to faster speed sessions like tempo runs and interval training.
The colorway you’re seeing in this review is from Nike’s “Glam Gods” (aka “Glam”) capsule, inspired by the Diamond League and built for spring marathon + track season.
It’s rolling out across Alphafly 3, Vaporfly 4, Zoom Fly 6, Streakfly 2, and Zoom Rival Fly 4; and because it’s a seasonal drop, sizes tend to disappear fast if people latch onto it.
Nike has positioned this shoe as a race day shoe with a carbon fiber plate and a dual-foam midsole that’s meant to balance bounce, durability, and stability.
After logging miles in them, I’m sharing my observations on where they shine and where they could use some refinement.

Key specifications
- Price: $170 at Nike.com
- Weight: 8.5oz / 241g (Men’s US 9)
- Drop: 8mm from heel-to-toe - 42mm (heel) / 34mm (forefoot), the highest stack height among its racing line
- Midsole: ZoomX foam (top layer) over SR-02 foam (bottom layer) with a full-length carbon fiber plate
- Outsole: Thin “web” of rubber that’s lighter yet still grippy with a midsole cutout
How they fit and feel
They fit true to size with a medium width, although the upper is comfortably snug, thanks to the dual-layer woven mesh that provides a reliable lockdown without feeling restrictive across the midfoot.
The toe box does run a bit snug for me but it's not narrow, so if you usually wear wide sizes, you will probably find it tight. Once on, the shoe feels stable despite its tall stack, and the step-in comfort is great, right out of the box.
Nike Zoom Fly 6 VS Zoom Fly 5
Compared to the Nike Zoom Fly 5 (a shoe that escaped my testing last year), the Zoom Fly 6 is 10% lighter and uses more ZoomX foam, which helps with energy return and an overall snappier feel.
The carbon plate also remains, but it’s a touch more flexible than in earlier Zoom Fly models. Some of that bounce still gets dialed down by the SR-02 foam underneath, so the change in performance isn’t as dramatic as you might expect. Even so, it’s a step forward in terms of comfort and reduced weight.

What’s good
One of the most noticeable improvements is how the midsole balances cushioning and responsiveness in daily runs and speed training.
It’s not as lively as a pure racing shoe, but it’s soft enough to keep your legs feeling fresher after a mid-length run.
The SR-02 foam (one of Nike's proprietary foams) that sits underneath also contributes to the shoe’s long-term durability by preventing the ZoomX from compressing too fast, so you end up with a midsole that stays consistent in feel over time.
I also like the more stable ride when compared to Nike's other pure racing shoes; the Alphafly 3 and Vaporfly 3. There’s enough stack height to absorb impact on longer outings, but I don’t feel wobbly due to this smart midsole layering, and a wider footprint / platform.
That stability is helped by the carbon fiber plate, which gives some extra structure when fatigue sets in.
It’s far less rigid than a racing plate (this includes the Vaporfly 3 and Alphafly 3), so the transitions feel more natural underfoot, and I don’t have that overly stiff sensation when I’m running at a moderate pace. This makes is a great option for speed training with.
Another highlight for me is the upper.
The dual-layer woven mesh might look simple, but the fit is reliable and comfortable once you dial in your laces and the outsole traction has proven to be very good.
It feels snug around the midfoot with decent lockdown, and the heel collar offers a secure wrap without pressing too hard on the Achilles thanks to the articulated heel counter design.
The overall package is also 10% lighter than the Zoom Fly 5, a weight differential that will be noticeable in daily training.
It also puts it on par, in weight (and price for that matter), with the awesome Saucony Endorphin Speed 5, and lighter than the Hoka Mach X 3 - both competitors to the Zoom Fly 6 in the Best Speed Training Shoes category (links to alastairrunning.com), right now.
Considering it’s priced at $180 (or $190 for this incredible Glam Gods colorway), it’s more affordable than Nike’s Vaporfly 4 ($260) or Nike Alphafly 3 ($295) and can fit well into your rotation if you want a plated shoe for varied workouts or marathon prep.
What’s not so good
The ZoomX layer, while an improvement, can feel somewhat muted under the new SR-02 foam. If you’re used to the lively pop of something like the Endorphin Speed 4, you might be left wanting more energy return in faster workouts.
The carbon plate’s flexibility also reduces the propulsive feel when you push the pace, so they're not the best all-out racing racing shoes but they're nowhere near as expensive as them either.
A more flexible plate means you feet aren't taxed as much during longer runs, so there are some serious benefits to a max cushion tempo running shoe like this one.
The midsole cutout can collect large stones/sticks if you step off the pavement and find yourself on a gravel path, so just be aware of that.
Traction has been really good so far, and the rubber compound seems very durable, which is great to see.
My verdict
Overall, for the price of $190 at Nike.com, the Zoom Fly 6 offers an excellent experience for runners who want a plated trainer that can handle daily mileage as well as fast tempo runs and of course race day efforts at a more affordable price.
It’s stable enough for longer efforts and will feel noticeably lighter than the Zoom Fly 5.
While it doesn’t match the energetic bounce found in some more premium models like the Alphafly 3 or Vaporfly 4 models, I still consider it a serious option for speed training and marathon prep.
If you’re a fan of Nike’s fit and prefer a bit more durability underfoot, it should be worth considering for your rotation.
