Puma Magnify Nitro 2 Long Run Review: A Steady Cruiser for Easy Miles

Introduction

The Puma Magnify Nitro 2 arrived ahead of its July 2023 launch, and a long 16k test at a comfortable 5:04 per km pace offered a solid picture of how this max-cushion trainer behaves over real distance. Run in around 14C conditions with only a light breeze, the shoe faced a genuine test of upper comfort, midsole resilience, and outsole grip across a mix of tarmac and gentle elevation.

The short version: this is a steady cruiser built for easy days and longer, slower efforts, and it does that job with a well-judged balance of cushioning and structure.

Upper and Fit: Comfortable and Adjustable

The upper proved breathable enough in mild UK warmth, helped by a stretchy toe box. Without that knit area, this could easily run warm, which matters as temperatures climb through summer. The fit feels true to size, with roughly a thumbs width of room at the front, and the padded tongue is thick enough to negate pressure without making the shoe feel overtly plush.

One of the best qualities here is the variable fit. Laces can be cinched down tight for a locked-in feel or dialed back for a more casual ride, and the shoe handled both in the same session. Lockdown is helped by power tape positioned on the medial side, which adds structure without stiff upper materials. There is enough give in the right places that no discomfort built up over the miles, and the feet felt fine afterward.

Compared with the first version, there is noticeably less padding, and the result feels like a clever iteration: Puma kept what worked and dropped what did not. The tongue materials even recall the original Nike Infinity React in a good way, and the upper is arguably more enjoyable on foot than some overly padded max-cushion rivals.

Midsole: Soft but Not Bottoming Out

The Nitro foam delivers a lovely soft, cushioned ride without feeling either brittle or squashy. The density balance absorbs impact well, helping preserve the legs, while still offering enough resilience to keep the ride lively. Over the full distance, the foam never bottomed out the way some softer foams do after a few miles.

It sits in the same category as the Asics Nimbus 25, though notably lighter, and the ride leans more plush than the Nike Infinity Run without relying on a rocker geometry. Nitro also flexes more than React. Shine a light through the outsole and you can spot a scattering of small holes across the midsole, likely there to allow a bit more compression and prevent the foam from flattening out.

At around 8 minutes per mile, this is a nice steady cruiser, and it picks up pace well despite the monstrous midsole stack. It is never going to be Puma’s most nimble shoe, but it never felt bulky or clunky either, and the extra mass even seems to add a little momentum. This is a shoe for easier days and longer, slower efforts rather than pace work.

Outsole: The Big Upgrade Over the Original

The biggest change from the original is the outsole. Rubber is distributed in four segments positioned at the four corners, allowing the shoe to flex far more. The result feels more nimble, less rigid underfoot, and easier to push off from, opening up more pace variation across training.

The layout is simple and effective, with a crash pad on the lateral side doing the job quietly, much like the famously no-nonsense Pegasus outsole. The shallow cutouts also mean far less rock and debris gets trapped than in Puma’s Forever Run Nitro, and the balance between rubber depth and durability looks well judged.

Grip was assured across the whole run with no hesitation in foot strike on dry, shoe-friendly terrain. Durability looks good enough that this could serve as a near-daily trainer, though something more nimble still makes sense for pace days. It is no race shoe, and that relaxed role allows for a generous application of rubber.

Buying Advice

Anyone after a comfortable, cushioned trainer for easy runs, long runs, and daily mileage should find a lot to like here. The upper suits runners who like to adjust fit pressure between snug and relaxed, and the Nitro midsole rewards those who want softness that does not collapse over distance. Runners chasing a fast, nimble tempo shoe should look elsewhere in Puma’s lineup.

Conclusion

The Magnify Nitro 2 is a thoughtful update: a softer-feeling, better-fitting upper, resilient Nitro cushioning that holds up over 16k, and a reworked segmented outsole that adds flexibility and grip. For easy days and longer efforts, it left the tester feeling fresh rather than beaten up, which is exactly what this kind of shoe should do.
