Puma Velocity Nitro 4 Review: A Retro Daily Trainer With Real Pace Versatility, Plus Two Alternatives to Consider
Puma's Velocity Nitro 4 gets a new aliphatic TPU foam and a bold retro design. We break down the ride, fit, and how it compares to the Adidas Adizero SL2 and On Cloudsurfer 2.
Introduction
The Puma Velocity Nitro 4 is a daily trainer that finally has some personality. Puma went full retro with the design, stacking overlays on overlays and finishing the midsole with a color fade straight out of a 1990s mall food court. But the bigger story is underneath: this year’s shoe uses a completely different midsole setup, with all-Nitro foam and no EVA base layer. The result is a workhorse daily trainer that is a lot more fun to run in than its predecessor.
At a stated weight of 250 g (8.8 oz), a 36 mm stack height with a 10 mm drop (26 mm in the forefoot), and a $140 retail price, the Velocity Nitro 4 sits squarely in the premium daily trainer bracket. It also holds its own against two strong competitors: the Adidas Adizero SL2 and the On Cloudsurfer 2.
Design and Fit: Retro Looks, Modern Materials
Puma clearly lets itself have more fun with the Velocity line, and the Velocity Nitro 4 leans hard into late-1990s and early-2000s running shoe cues. Stripes on top of the toe box narrow its visual profile, while the side of the shoe layers a TPU base along the lace loops, a micro suede layer with a reflective portion on top, and a felt-like layer above that. The heel cup adds more layering, including rubber pads that give a nice finger grip when pulling the shoe on, speed holes on one side, and a flame-engulfed cat logo on the other. The crowning retro touch is the blue-to-seafoam-green color fade in the midsole.

Despite all the retro accents, the upper is very much a modern material: relatively breathable and not too heavy. The trade-off is a heavily padded heel cup that soaks up sweat in summer conditions and stays damp long after a run. In terms of fit, the shoe runs true to size for a normal running shoe size, with a fit that leans slightly slim but feels a touch more comfortable than last year’s version thanks to the material changes.
Ride and Performance
The updated all-Nitro foam, an aliphatic TPU formulation tweaked for daily training rather than racing, is nicely cushioned, especially in the heel. Heel strikers will really feel the softness the TPU foam provides, and the bubble-patterned heel area emphasizes that the back of the shoe is meant to be a big crash zone. Because the foam is tuned for durability rather than racing, Puma no longer needs the EVA base layer used in the Velocity Nitro 3.

The forefoot tells a different story. It is not quite as soft as some runners might prefer, and the foam sits on the firmer side, but that firmness comes with a real upside: responsiveness. There is a pleasant bounce out of the front of the shoe, which gives it genuine pace versatility. Beyond everyday easy miles and long runs, it can handle strides and early-season faster workouts when you are not ready to break out a carbon-plated race shoe yet.
Underfoot, Puma Grip provides almost full rubber coverage, with just a small patch of exposed foam under the arch. The outsole is both highly durable and nicely grippy, which suits a shoe intended to absorb most of your weekly mileage. The plush heel also makes it a genuinely comfortable walking shoe, so it can double as a lifestyle sneaker without feeling like a compromise.
Alternatives: Adidas Adizero SL2 and On Cloudsurfer 2
The first shoe worth comparing is the Adidas Adizero SL2. It uses a dual-density approach: regular Lightstrike, an EVA-based foam, combined with Lightstrike Pro, one of Adidas’ race-caliber foams, inserted inside. Like the Velocity Nitro 4, it is a daily trainer with a ride that is not overly squishy but is nicely bouncy and more responsive than typical daily trainers. The Adizero SL2 is less comfortable on long runs, particularly in the heel, which may help you decide between the two. At a $130 full retail price, and sometimes available at steep discounts, it becomes hard to ignore at the right price.
The On Cloudsurfer 2 is the other close comparison. This year’s version was firmed up, with a reformulated foam that changes the compression and decompression dynamics. It is comfortable but again slightly firmer than ideal, while remaining responsive enough to pick up the pace when needed. It is comfortable in the heel and looks great for lifestyle wear, making it a fairly head-to-head experience with the Velocity Nitro 4, though with a modern, streamlined aesthetic rather than a retro one. That On branding comes at a premium: $160.

Buying Advice
The Velocity Nitro 4 launched at $140, five dollars more than last year’s Velocity Nitro 3, which still retails at $135 on Puma’s own site. Given the small price difference, waiting for the Velocity Nitro 4 makes sense if you prefer the more characterful new version; the previous model feels considerably more generic by comparison. If you shop around, stick to retailers you trust, and be wary of deals that look too good to be true.

Within a broader rotation, the Velocity Nitro 4 works as the everyday shoe for most runs, with a max-cushion option such as the Puma Mag Max for recovery days and a lighter tempo shoe for harder sessions. For runners who want a little guidance against their foot collapsing inward, the Puma ForeverRun 2 is a lightly stabilized sibling with guide rails rather than heavy stability elements, though it rides slightly firmer.
Conclusion
The Puma Velocity Nitro 4 injects character into a daily trainer that previously looked decent but lacked personality. With all-Nitro aliphatic TPU foam, a plush heel, a responsive forefoot, and durable Puma Grip coverage, it is a versatile daily trainer that can also stretch into faster sessions and lifestyle wear. The Adidas Adizero SL2 is a strong value alternative for bouncy, responsive daily miles, and the On Cloudsurfer 2 suits runners who want a similar firmer-but-responsive ride in a more modern package. If you want one shoe that does a bit of everything with genuine style, the Velocity Nitro 4 is the one to beat.
