Running enthusiasts are always on the lookout for shoes that strike the perfect balance between comfort, performance, and value. In 2025, two brands have been dominating the running shoe scene: Puma and AS6. Both are producing innovative designs, but today we’re taking a closer look at Puma’s Velocity Nitro 4, the latest daily trainer in their lineup.

With a focus on lightweight performance, bouncy energy return, and exceptional comfort, the Velocity Nitro 4 has already made waves among runners. This review will cover every aspect of the shoe, from fit and feel to cushioning, stability, and overall value.
Whether you’re a seasoned marathoner or a casual runner, this detailed analysis will help you decide if the Puma Velocity Nitro 4 is the right choice for your training needs.
Puma Velocity Nitro 4: First Impressions
When unboxing the Puma Velocity Nitro 4, the first thing that stands out is its surprisingly light feel. Unlike its predecessor, the Velocity Nitro 3, which had a dual-layer foam midsole, the Nitro 4 features a full slab of Nitro Foam, giving it a softer and bouncier feel.
The shoe weighs just over 9 ounces, making it lighter than competitors like the Mizuno Neo Zen, Adidas Evo SL, and AS6 Mega Blast.
From the first touch, the shoe feels airy yet substantial, with a Puma Grip outsole that promises durability and traction. The padded heel collar and fully gusseted tongue indicate that Puma prioritized comfort, while reflective laces add a subtle touch of visibility for early morning or evening runs.
Midsole Technology and Performance
Full Nitro Foam Cushioning
The standout feature of the Velocity Nitro 4 is its full Nitro Foam midsole. Unlike the previous version, which had a firmer layer at the bottom, this shoe provides consistent softness throughout. The foam is bouncy, offering excellent energy return that motivates you to pick up the pace during daily runs.
The foam is produced using an aliphatic TPU (ATPU) process, which injects nitrogen into the material to enhance its compressive and rebound properties. This results in a midsole that is not only soft but also highly responsive. Whether you’re doing easy runs, tempo sessions, or moderate intervals, the shoe adapts smoothly to your stride.
Comparison to Competitors
When placed alongside the Mizuno Neo Zen and Adidas Evo SL, the Velocity Nitro 4 holds its own. While the Neo Zen and Evo SL feature slightly taller midsoles, the Nitro 4’s lightweight design and softer cushioning make it feel faster and more agile. For runners who prefer a more natural, traditional running shoe feel without sacrificing modern foam technology, the Nitro 4 hits the sweet spot.

Outsole Design and Traction
The Puma Grip outsole is engineered to provide durability without adding unnecessary weight. The traction pattern is designed for road running, ensuring a stable grip on both dry and slightly wet surfaces. Compared to the Nitro 3, which had a stiffer and more rigid outsole, the Nitro 4 is flexible, allowing for a smoother transition from heel to toe.
The trench cutouts and grooves in the outsole enhance flexibility, making the shoe torsionally compliant. This flexibility, combined with the lightweight Nitro Foam, contributes to the overall “bouncy” sensation that runners often describe as springy or lively.

Upper Design and Fit: Puma Velocity Nitro 4 Review
Traditional Yet Functional Upper
The Velocity Nitro 4 features a more traditional mesh upper that balances breathability, support, and comfort. Unlike shoes with a “bootie” style, this shoe maintains a classic tongue-and-lace configuration, which allows for adjustable fit and better lockdown. The fully gusseted tongue prevents the lace area from shifting, while padding around the heel enhances comfort during longer runs.
Narrow Fit Considerations
It’s important to note that Puma shoes, including the Nitro 4, tend to run narrow, particularly in the forefoot. Runners with wider feet may find this restrictive. However, for those with a standard or slightly narrow foot, the shoe offers a snug, racing-shoe type fit that enhances responsiveness and stability during faster runs.
Weight and Stack Height
The Velocity Nitro 4 weighs just 9.3 ounces, a significant reduction from the Gore-Tex version of the Nitro 3, which weighed 11.8 ounces. This 2.5-ounce difference is substantial for runners who prioritize lightweight performance.
The shoe features a 10 mm drop (heel 36 mm, forefoot 26 mm), providing enough heel lift to facilitate a natural running gait while maintaining good ground feel. The stack height is moderate, making it suitable for daily training without feeling bulky or heavy.

Running Experience
Daily Training Performance
On the road, the Velocity Nitro 4 lives up to expectations as a daily trainer. Its soft and bouncy midsole encourages faster running even during easy-paced workouts. Many runners have noted that the shoe motivates them to pick up the pace thanks to its responsive energy return.
The combination of lightweight foam, grippy outsole, and snug upper ensures a secure and enjoyable running experience. While it’s not a racing shoe with extreme propulsion, it performs exceptionally well as a versatile daily trainer for various paces and distances.
Stability and Support
While the shoe excels in comfort and responsiveness, its neutral design may not offer enough stability for overpronators or runners seeking significant torsional support. The lightweight, flexible build prioritizes speed and agility over structured stability, making it best suited for runners who prefer a natural, midfoot-to-toe feel.

Comparison to Puma Velocity Nitro 3
The transition from the Nitro 3 to Nitro 4 is marked by several key differences:
- Midsole: Nitro 3 had a dual-layer foam with a firmer bottom; Nitro 4 uses a single soft, bouncy slab of Nitro Foam.
- Weight: Nitro 4 is 2.5 ounces lighter than the Nitro 3 Gore-Tex version.
- Flexibility: Nitro 4 bends easily in all directions, while Nitro 3 is stiffer and more torsionally resistant.
- Upper Design: Nitro 4 features a traditional mesh upper with a gusseted tongue, while Nitro 3’s Gore-Tex upper was more insulated and rigid.
These updates make the Nitro 4 a more comfortable, responsive, and versatile daily trainer compared to its predecessor.
Value for Money
At a retail price of $140, the Puma Velocity Nitro 4 offers exceptional value. Many shoes in this price range either compromise on cushioning, weight, or durability, but the Nitro 4 delivers all three. For runners seeking a high-quality daily trainer without spending $200 or more, this shoe is an excellent investment.

How It Compares to Competitors
Mizuno Neo Zen
The Neo Zen has a slightly higher stack and firmer midsole compared to the Nitro 4. While it offers more stability and a cushioned ride, it lacks the same level of bounce and lightweight feel, making the Nitro 4 feel more lively on shorter or faster runs.
Adidas Evo SL
The Evo SL is in the same price and weight category as the Nitro 4. It has a responsive midsole but is slightly stiffer. Runners looking for a soft, flexible, and airy experience may prefer the Nitro 4 over the Evo SL.
AS6 Mega Blast
The AS6 Mega Blast is a worthy competitor in 2025, but it generally comes in heavier with a less traditional fit. The Nitro 4’s lightweight feel, narrower fit, and classic upper make it an attractive option for runners who value comfort and responsiveness.
Final Verdict
The Puma Velocity Nitro 4 is a standout daily trainer in 2025. Lightweight, bouncy, and comfortable, it delivers excellent performance at an affordable price. While the narrow fit may not suit all runners, those with standard or slightly narrow feet will appreciate its responsive feel and snug lockdown.
With its full Nitro Foam midsole, durable outsole, and thoughtfully designed upper, the Nitro 4 is a shoe that makes everyday runs more enjoyable and energizing. Whether you’re training for speed or simply want a dependable daily trainer, the Velocity Nitro 4 is a top choice in its category.
