On the other hand, the Saucony Endorphin Pro 3 also offers a true-to-size fit, with its FORMFIT design hugging every part of your foot while allowing for natural movement.

Cushioning:

Both shoes prioritize cushioning, but they approach it differently. The Nike Air Zoom Alphafly Next% features ZoomX foam, a highly responsive and lightweight material that provides exceptional cushioning.

Additionally, the shoe incorporates Zoom Air pods in the forefoot for added responsiveness and energy return. The Saucony Endorphin Pro 3, on the other hand, utilizes PWRRUN PB cushioning, known for its pillowy softness and responsiveness, allowing you to move quickly and comfortably.

Stability:

The Nike Air Zoom Alphafly Next% is designed to be stable for heel, midfoot, and forefoot strikers, making it a versatile option for runners with different foot strike patterns.

However, the Saucony Endorphin Pro 3 is categorized as a neutral shoe, meaning it doesn’t provide additional stability features for overpronators or underpronators.

Value for Money:

While both shoes carry a premium price tag, the Saucony Endorphin Pro 3, priced at $225, offers a more affordable option compared to the Nike Air Zoom Alphafly Next%, which retails for $275.

However, it’s important to consider that the higher price of the Alphafly Next% reflects its cutting-edge technology and materials, which may justify the investment for some runners.

Performance comparison:

For Walking:

Both the Nike Air Zoom Alphafly Next% and the Saucony Endorphin Pro 3 are primarily designed for running, but they can also perform well during walking.

The Alphafly Next%’s ZoomX foam and Zoom Air pods provide excellent cushioning and responsiveness, making it a comfortable option for long walks.

Similarly, the Endorphin Pro 3’s PWRRUN PB cushioning offers a soft and bouncy ride, ensuring comfort during walking sessions.

For Running:

When it comes to running, both shoes excel in their own ways. The Nike Air Zoom Alphafly Next% is designed specifically for marathon running, with its highly cushioned ZoomX foam midsole and carbon plate providing a propulsive and responsive ride.

The Saucony Endorphin Pro 3, on the other hand, is suitable for various types of fast running, including racing, tempo running, and interval training. Its SPEEDROLL Technology encourages a smoother and easier run, helping you roll from heel to toe with less effort.

For Standing All Day:

While neither shoe is explicitly designed for standing all day, the cushioning and support provided by both models can make them suitable for extended periods of standing.

The Nike Air Zoom Alphafly Next%’s ZoomX foam and Zoom Air pods offer excellent shock absorption and cushioning, potentially reducing fatigue during prolonged standing.

Similarly, the Saucony Endorphin Pro 3’s PWRRUN PB cushioning and FORMFIT design can provide comfort and support for those who need to be on their feet for extended periods.

For Plantar Fasciitis:

Plantar fasciitis is a common condition that causes heel pain, and both the Nike Air Zoom Alphafly Next% and the Saucony Endorphin Pro 3 have features that can potentially alleviate the discomfort associated with this condition.

The Alphafly Next%’s highly cushioned midsole and Zoom Air pods in the forefoot can help absorb impact and reduce stress on the plantar fascia.

Similarly, the Endorphin Pro 3’s PWRRUN PB cushioning and S-Curve carbon-fiber plate can provide shock absorption and facilitate a smoother transition from heel strike to toe-off, potentially reducing strain on the plantar fascia.

Conclusion:

Both the Nike Air Zoom Alphafly Next% and the Saucony Endorphin Pro 3 are exceptional running shoes, offering cutting-edge technologies and innovative features. The choice between these two models ultimately depends on your specific needs, preferences, and running goals.


If you’re a dedicated marathon runner seeking a highly cushioned and propulsive ride, the Nike Air Zoom Alphafly Next% might be the better option.

Ultimately, trying on both shoes and assessing their performance based on your individual requirements will help you make the most informed decision.
