Nike Invincible 3 vs Puma Magnify Nitro 2: Which Max-Cushion Trainer Makes More Sense?

Introduction

The Nike Invincible 3 and Puma Magnify Nitro 2 sit in the same corner of the running shoe market: big stack heights, generous cushioning, and a comfort-first attitude aimed at easy runs, long runs, and everyday mileage. On paper they look nearly interchangeable. In practice, our testing found them heading in very different directions.

The short version: the Magnify Nitro 2 is the more balanced, more versatile, and better-value shoe of the two, while the Invincible 3 leans on a uniquely bouncy foam feel that comes with real trade-offs in stability, weight, and price. Here is how they compare.

Specs and Price: Close on Paper, Far on Value

Both shoes carry 40mm of stack at the heel. The Puma’s drop is 10mm, putting it at 30mm in the forefoot, while the Nike’s 9mm drop brings it down to 31mm. Weight is where they separate: the Invincible 3 is the heavier of the pair at 316g (11.1oz) in a UK size 9, against 298g (10.5oz) for the Magnify Nitro 2.

Pricing tells a bigger story. The Magnify Nitro 2 costs £130 or $140, while the Invincible 3 sits at £170 or $180. That is a meaningful gap for two shoes in the same category, and it matters even more when the cheaper shoe also proves to be the better all-rounder.

Upper, Fit, and Sizing

The Magnify Nitro 2 uses an engineered mesh upper with plenty of padding around the tongue and heel, plus a touch of extra medial structure from Puma’s power tape. The Invincible 3 counters with a Flyknit upper and a somewhat unusual heel design. There is padding there, but it is less generous than most shoes in this category, which raises a genuine concern about heel slippage.

On fit, both testers found the shoes true to size with a roomy forefoot and no narrow feel. One tester in UK 9s reported a slightly loose heel on the Nike, though it never caused real problems on the run for him; other runners have had worse experiences with it, so it is something to watch. The other tester, in his normal US 10 for both brands, was perfectly happy with the fit of both. A heel clip embedded into the foam adds some structure at the back of the Invincible 3, which it needs given what sits above it.

Midsole and Ride Feel

This is where the comparison gets interesting. The Magnify Nitro 2 now runs a full Nitro foam midsole, Puma’s nitrogen-infused TPE foam, replacing the dual-density EVA blend of the original model. The result is a shoe that is well cushioned but not purely soft, with enough resilience to bounce you back and make the ride more versatile and more enjoyable. Testers found it smooth through the gait cycle despite lacking a big rocker, and comfortable enough that forefoot discomfort from snapping through off the heel never showed up.

The Invincible 3 is built around a very large ZoomX midsole, Nike’s soft, bouncy racing foam. ZoomX in a max-cushion trainer still gives the shoe a ride unlike anything else in the category, but our testing found that the magic of the earlier Invincible models has faded. The third version feels more stable on paper thanks to the heel clip and a generally wide design, yet it also feels less fun, and the stability gains do not fully fix the wobble. One tester described the ride as mushy at times, lacking direction, and noted that testing coincided with a knee niggle that the shoe’s instability did not help. Other runners have reported similar issues. It is a shoe you need to be in the right frame of mind and body to use.

Outsole and Grip

Puma’s GRIP outsole is a consistent strength across the brand’s range, and the Magnify Nitro 2 benefits from a thick layer over all the key impact areas. There are some exposed foam sections, so it is not complete coverage, but the material itself is excellent.

Nike goes the other way with very extensive waffle tread coverage, essentially a full outsole where the Puma leaves some foam showing. On durability and wet-road confidence, though, testers rated the Puma’s outsole as the stronger performer of the two.

Everyday Versatility

The Magnify Nitro 2 slots neatly into the world of shoes like the Saucony Triumph: a cushioned daily trainer that can do more than just sink into easy miles. Testers found it handled progression runs during marathon training without fuss, comfortably spanning paces from around 4:35 down to 3:45 per kilometre. It is not a speed-work shoe, but it moves through the gears smoothly when you want to pick up the pace.

The Invincible 3, by contrast, narrows its own use case. Earlier versions earned their place as fun, cozy recovery-run shoes; the third version keeps the bounce but loses much of the enjoyment, and testers rarely reached for it as a result. It slows you down rather than lifting the run, and with far more strong competition in the max-cushion space now, that narrow appeal is harder to justify.

Which One Should You Buy?

For easy runs, daily miles, or a one-shoe rotation, the Magnify Nitro 2 is the clear pick. It is lighter, cheaper, more stable, and more versatile, with a balanced ride that is comfortable without being dramatic, a great outsole, and a dependable fit. As a bonus, Puma shoes frequently show up in sales, so it is worth keeping an eye out for a deal. It landed comfortably in our testers’ top picks for cushioned daily trainers this year.

The Invincible 3 is genuinely hard to recommend right now. The high price, added weight, lingering instability, and a ride that has lost the charm of the first two versions all count against it. If you love the ZoomX feel, the Invincible 2 may be worth hunting down while stock remains. But for most runners choosing between these two, the Puma is the shoe that ticks more boxes.

Conclusion

The Invincible 3 still offers a ride that nothing else quite matches, but the Magnify Nitro 2 is the better shoe for more runners: more versatile, more stable, lighter, and significantly cheaper. For a max-cushion daily trainer that simply works, the Puma wins this comparison.
