As a runner who has achieved a 1:09 half marathon time, I've had the opportunity to test and experience a wide range of running shoes, including the Nike Alphafly 2.
I'm excited to share my comprehensive review of the Nike Alphafly 2, a shoe that has truly impressed me both in racing and training scenarios.
In this detailed Nike Alphafly 2 review, I'll explain why I believe this shoe is an excellent addition to any serious runner's collection.
What is the Nike Alphafly 2?
Nike released the Nike Alphafly 2 in 2022, and I picked up a pair in early 2023. This means I've had a year of experience with these shoes, putting them through their paces in various conditions and scenarios.
This extended testing period provides me with a thorough, long-term perspective on their performance and durability.
The Alphafly 2 sits at the very top of Nike's running shoe lineup, positioned as their premium racing shoe. It's particularly aimed at marathon runners, though as we'll discuss later, its versatility extends to other distances and training scenarios.
The Alphafly 2 shares the spotlight for one of the best racing shoes ever with the extremely popular Nike Vaporfly 3, another widely used racing shoe among runners worldwide. While both shoes are designed for speed, they have some distinct differences that we'll explore throughout this review.
The shoe is known for its exceptional comfort and speed, particularly over longer distances, making it a favorite among elite athletes like Eliud Kipchoge.
Who Created the Alphafly 2?
Of course, the Alphafly 2 is a Nike shoe and a product of Nike's innovative design team. It follows in the footsteps of the original Alphafly, which made waves in the running community with its groundbreaking technology.
The development of the Alphafly 2 was driven by the huge success of its predecessor, with Nike's engineers and designers working to refine and improve upon an already impressive formula.
Creating the Alphafly 2 is part of Nike's ongoing commitment to pushing the boundaries of running shoe technology. The shoe incorporates lessons learned from the original Alphafly, feedback from elite athletes, and the latest materials and design techniques advancements.
Top Benefits of the Nike Alphafly 2
Zoom Air Pods: One of the key differentiators between the Alphafly and the Vaporfly is the inclusion of Zoom Air pods. These units, positioned strategically in the forefoot, provide an unparalleled sense of responsiveness.
When running in the Alphafly 2, you can feel these pods working, giving you a distinct sensation of being propelled forward with each stride. The Air Zoom units contribute significantly to this performance, offering a responsive yet firm ride that aids in propulsion and energy return.
This technology is particularly beneficial during longer races or training runs, where maintaining your pace can become challenging as fatigue sets in.

Exceptional Comfort: The comfort level of the Alphafly 2 is truly remarkable. What sets it apart is how this comfort is maintained over extended periods. I've completed 20-mile training runs in these shoes, and they felt just as comfortable at the end as they did at the start.
This sustained comfort is crucial for marathon runners or those engaging in long training sessions. The shoe's ability to provide consistent comfort can help reduce fatigue and maintain proper form, even in the later stages of a long run.
Impressive Durability: Despite being marketed primarily as a racing shoe, the Alphafly 2 has proven surprisingly durable. I regularly use mine in training, a testament to their build quality. While it's true that they come with a premium price tag, the durability factor significantly enhances their value proposition.
The ability to use these shoes beyond race day scenarios means you're getting more bang for your buck, making them a wise investment for serious runners.
The Best Features of the Nike Alphafly 2
Zoom Air Pods:
The Zoom Air pods are strategically located in the midfoot to forefoot area, aligning perfectly with where your foot ideally strikes the ground. This placement serves a dual purpose: it provides excellent energy return, propelling you forward with each step while also offering superior shock absorption.
This shock absorption is crucial for reducing the impact on your joints during long runs or races, potentially helping to stave off fatigue and reduce the risk of impact-related injuries. The Nike Zoom Alphafly Next% 2 is a leading option for marathon racing, known for its speed, cushioning, and comfort, making it a top choice for many runners.
Improved Outsole
Nike has enhanced the outdoor sole of the Alphafly 2, and the grip feels better now. This improvement is noticeable and significant in my experience. I've had no issues with traction, even in wet weather conditions.
Perhaps more importantly, I feel confident descending at speed in these shoes, which is crucial for maintaining momentum and pace during races with varied terrain.

ZoomX Foam:
The Alphafly 2 features a generous amount of Nike's ZoomX foam, which is known for its excellent energy return and lightweight properties.
The ample ZoomX foam in the Alphafly 2 works in concert with the Zoom Air pods and carbon plate to create a shoe that feels like it's actively assisting your forward motion. The foam also contributes to the shoe's comfort, providing a plush yet responsive feel underfoot.
Full Carbon Plate:
Like its sibling, the Vaporfly, the Alphafly 2 incorporates a full-length carbon fiber plate. This plate serves multiple purposes. It adds rigidity to the shoe, which helps in energy transfer and forward propulsion.
It also helps to distribute the forces from the Zoom Air pods and ZoomX foam more evenly across the foot. The result is a shoe that feels both stable and dynamic, helping to maintain your pace over long distances.
The Pros and Cons of the Nike Alphafly 2
When investing in a premium running shoe like the Alphafly 2, it's crucial to clearly understand its strengths and potential drawbacks. Here's a balanced look at the pros and cons based on my extensive experience with the shoe:
Pros of the Nike Alphafly 2:
Exceptional Durability: As mentioned earlier, the longevity of the Alphafly 2 is impressive. I've owned the shoe for a year and have logged a significant number of miles in them.
Initially, I had planned to reserve these shoes exclusively for racing, but their performance and durability have been so impressive that I've incorporated them into my regular training routine.
They've proven particularly beneficial on days when my legs feel fatigued, helping me push through challenging sessions and steady runs.
Unmatched Bounce and Energy Return: The energy return in the Alphafly 2 is, in my experience, unparalleled in the world of super shoes. The combination of the Zoom Air pods, ZoomX foam, and carbon plate creates a sensation of being propelled forward that I haven't experienced in any other shoe.
This responsiveness translates to noticeably less effort required to maintain faster paces, which can be a game-changer in long-distance races or grueling training sessions.
Versatility Across Various Runs and Races: The Alphafly 2 has proven remarkably versatile. While it's primarily marketed as a marathon shoe, I've found it performs admirably across a range of distances and training scenarios.
From tempo runs to long, steady efforts, the shoe adapts well to different paces and distances. That said, for shorter, all-out efforts like 5K or 10K races, I might lean towards a more stripped-down option like the Vaporfly 3. However, the Alphafly 2's versatility is a significant advantage, especially for runners who prefer investing in a single high-performance shoe for training and racing.
Cons of the Nike Alphafly 2:
High Stack Height: While the substantial stack height contributes to the shoe's comfort and bounce, it can present challenges for some runners. Personally, I've found that the elevated platform can sometimes put additional stress on my Achilles tendon and calf muscles.
This is particularly noticeable if I use the shoe too frequently without rotation. As a result, I recommend rotating the Alphafly 2 with other shoes in your collection, particularly for easy runs or speed workouts where a lower stack height might be beneficial.
Inconsistent Lockdown: One area where the Alphafly 2 falls slightly short of expectations is its lockdown. I sometimes struggle to achieve as firm a fit as I would like, especially when compared to shoes like the Nike Vaporfly. This is a relatively minor issue that potential buyers should be aware of, especially if they have narrow feet or prefer a very snug fit.
Nike Alphafly 2 Alternatives
While the Alphafly 2 is undoubtedly one of the best racing shoes available, particularly for long distances, it's always worth considering alternatives to ensure you find the perfect shoe for your needs. Here are some comparable options:
Saucony Men's Endorphin Elite: This shoe from Saucony offers a compelling alternative to the Alphafly 2. It features a high-quality upper and incorporates Saucony's PWRRUN HG foam along with a carbon plate for energy return. The Endorphin Elite is designed to compete directly with Nike's super shoes and has received positive reviews from many runners.
Puma Deviate Nitro Elite 2: If you're looking for a more budget-friendly option that still offers high performance, the Puma Deviate Nitro Elite 2 is worth considering. It includes a carbon plate and is designed to help you set new personal bests in the marathon. While it may not have the same level of cushioning as the Alphafly 2, it offers a responsive ride at a lower price point.
Nike Vaporfly 3: For those focused on shorter distances like 5K or 10K, or for runners who prefer a slightly more stripped-down feel, the Nike Vaporfly 3 is an excellent choice.
My Experience Using the Nike Alphafly 2
After extensive use, I can confidently say that the Alphafly 2 is an excellent all-around shoe. While I initially purchased it solely for racing purposes, I quickly incorporated it into my training regimen, particularly for longer runs.
In my experience, it's one of the most durable super shoes I've owned. I attribute this durability to both the well-constructed upper and sole, as well as the generous amount of foam and substantial stack height.
One of the most impressive aspects of the Alphafly 2 is its consistent performance over time. Even after logging many miles in these shoes, I haven't noticed any significant drop in performance. The energy return, comfort, and responsiveness remain largely unchanged, which is a testament to the quality of materials and construction.
However, it's important to note that the high stack height can potentially aggravate certain niggles if the shoe is used too frequently. This is particularly true for me during intense training weeks. As a result, I strongly recommend rotating the Alphafly 2 with other shoes, especially for easy runs or speed workouts where a lower stack height might be beneficial. This rotation strategy helps to work different muscle groups and reduce the risk of overuse injuries.
It's also crucial to remember that while the Alphafly 2 is excellent at providing comfort and helping you run faster, it's not a magic solution. To truly avoid injury and improve performance, it's essential to complement your running with a robust cross-training and strength training program. The shoe can enhance your performance but can't replace the fundamental work required to become a stronger, more resilient runner.
How Does the Nike Alphafly 2 Perform in Different Conditions?
Wet Weather: The Alphafly 2 performs admirably in wet conditions. I haven't experienced any significant issues with grip, even when running on wet roads. I feel confident running downhill at faster paces even in damp conditions, which is crucial for maintaining momentum during races.
Hot/Warm Weather: In warmer conditions, I've found that my feet stay relatively cool, thanks to the breathable upper. The design is similar to that of the Vaporfly 3 in this regard, allowing for good air circulation.
Nike Alphafly 2: The Upper
Road: As expected, the Alphafly 2 excels on road surfaces. It's clearly designed with road running in mind, and this is where it performs at its best. However, it's worth noting that cornering can be slightly more challenging compared to shoes with a lower stack height. This is something to be mindful of, especially during races with tight turns.
Grass: On short grass surfaces, the Alphafly 2 performs reasonably well. However, this isn't its primary terrain, and you may notice a decrease in responsiveness compared to road running.
Trail: I would not recommend using the Alphafly 2 for trail running, except perhaps on very well-maintained gravel paths. The high stack height and road-oriented outsole are not designed for off-road or technical trail running. For these conditions, you'd be better off with a dedicated trail running shoe that offers more stability and grip.
How Does the Nike Alphafly 2 Fit into My Current Shoe Rotation?
Tempo Runs: The Alphafly 2 excels during tempo runs. Its responsive nature makes holding a fast pace feel more comfortable, and it provides a stable ride even as you push the pace. The energy return from the Zoom Air pods and ZoomX foam is particularly noticeable during these higher-intensity efforts.
Steady Runs: Interestingly, I find the Alphafly 2 performs well even at slower, steady paces. Unlike some other super shoes that can feel unstable at slower speeds, the Alphafly 2 remains comfortable and supportive. This versatility is likely due to the substantial midsole foam, which provides a plush ride even at moderate paces.
Long Runs: The Alphafly 2 truly shines during long runs, especially those incorporating sustained periods at marathon pace. The shoe's cushioning and energy return properties really come into play over longer distances. One of the most noticeable benefits is the reduced muscle soreness following long runs. The shoe's ability to mitigate impact seems to result in quicker recovery times, which can be crucial during heavy training blocks.
Race Day: When it comes to race day, the Alphafly 2 is my go-to choice for half marathons and marathons. For 10K races, the decision between the Alphafly 2 and the Vaporfly 3 is more nuanced and often comes down to the specific course and how I'm feeling on the day. Both are excellent options in the Nike super shoe lineup.
Should You Buy the Alphafly 2?
I would strongly recommend the Alphafly 2, especially if you're training for or planning to run a marathon. The shoe's design, with its wider platform compared to some other super shoes, may also make it a good choice for runners with wider feet who have struggled with the fit of other racing shoes.
The Nike Alphafly 2 is undoubtedly a high-performance shoe. It shares many of the same technologies as the Vaporfly, such as the full-length carbon plate and ZoomX foam, but with the addition of the Zoom Air pods. These features combine to make it one of the best racing shoes currently available on the market.
If you already own the Alphafly 1 and are considering an upgrade, it's worth noting that the performance differences between the two models are relatively subtle. The original Alphafly was already an exceptional shoe. The Alphafly 2 features a slightly higher stack height and improved grip, which were the two most noticeable changes for me. Whether these improvements justify an upgrade will depend on your personal preferences and budget.
Conclusion
In conclusion, the Nike Alphafly 2 is a remarkable shoe that has earned its place among the top of the running shoe hierarchy. Its blend of comfort, performance, and durability make it an excellent choice for serious runners looking to maximize their potential in training and races.
While it comes with a premium price tag, its versatility and longevity help justify the investment. As with any running shoe, it's important to consider your individual needs, preferences, and running style when making a decision.
But for those seeking a top-tier marathon racing shoe that can also handle the rigors of training, the Alphafly 2 is certainly worth considering.
