On the other hand, the Adidas Adizero Prime X boasts a lightweight rubber outsole and a Celermesh 2.0 upper, known for its ventilation and seamless fit.

Durability:

Both shoes are designed for high-mileage training and racing, but the Nike AlphaFly Next% may have a slight edge in durability due to its thick rubber outsole and reinforced upper.

However, the EnergyRods technology in the Adizero Prime X could potentially contribute to improved longevity by distributing impact forces more effectively.

Fit:

The Nike AlphaFly Next% is reported to fit true to size, with the Atomknit upper providing a secure and adaptable fit. Similarly, the Adidas Adizero Prime X is also said to run true to size,

with the Celermesh 2.0 upper contributing to a comfortable and snug fit. However, individual preferences and foot shapes may vary, so trying both shoes on is recommended.

Cushioning:

The Nike AlphaFly Next% features the responsive and highly cushioned ZoomX foam, along with Zoom Air pods in the forefoot for added cushioning and energy return.

The Adidas Adizero Prime X, on the other hand, boasts the brand’s LightStrike Pro cushioning system, which incorporates three layers of resilient foam for optimal shock absorption and energy return.

Stability:

Both shoes offer excellent stability for a variety of foot strike patterns. The Nike AlphaFly Next% is designed to be stable for heel, midfoot, and forefoot strikers,

While the Adidas Adizero Prime X features the SlingLaunch Heel construction, which keeps the foot locked in and supported throughout the stride.

Value for Money:

With a retail price of $275, the Nike AlphaFly Next% is a premium option, but its advanced features and technologies may justify the cost for serious runners. The Adidas Adizero Prime X,

at $250, is slightly more affordable while still offering cutting-edge technologies like EnergyRods and LightStrike Pro cushioning, making it a compelling option for those seeking top-tier performance at a slightly lower price point.

Performance Comparison:

For Walking:

While both shoes are primarily designed for running, the Nike AlphaFly Next% and the Adidas Adizero Prime X can also be suitable for walking. The AlphaFly Next%’s highly cushioned ZoomX foam and Zoom Air pods provide excellent shock absorption and comfort for extended periods of walking.

Similarly, the Adizero Prime X’s LightStrike Pro cushioning system offers responsive and supportive cushioning for everyday walks.

For Running:

Both shoes excel in their intended purpose – running. The Nike AlphaFly Next% is engineered specifically for marathon runners, with its propulsive ride and stable platform supporting various foot strike patterns.

The Adidas Adizero Prime X, on the other hand, is a boundary-pushing conceptual long-distance running shoe, designed to amplify the key features of the Adios Pro 2 while incorporating innovative technologies like EnergyRods and carbon-infused blades for enhanced energy return and responsiveness.

For Standing All Day:

While not primarily designed for prolonged standing, both shoes offer features that could make them suitable for extended periods of standing. The Nike AlphaFly Next%’s ZoomX foam and Zoom Air pods provide excellent cushioning and support, reducing fatigue and discomfort.

Similarly, the Adidas Adizero Prime X’s LightStrike Pro cushioning system and SlingLaunch Heel construction could help alleviate pressure and maintain comfort during long periods of standing.

For Plantar Fasciitis:

Plantar fasciitis, an inflammation of the plantar fascia, requires shoes with ample cushioning and support.

The Nike AlphaFly Next%’s highly cushioned ZoomX foam and Zoom Air pods could potentially help alleviate the discomfort associated with plantar fasciitis, but the stiff forefoot may not be ideal for those with this condition.

The Adidas Adizero Prime X, with its layers of LightStrike Pro cushioning, could also provide the necessary support and shock absorption, but its flexibility in the forefoot area is not well-documented.

Conclusion:

In the battle between the Nike AlphaFly Next% and the Adidas Adizero Prime X, there is no clear winner – the choice ultimately depends on your specific needs and preferences.


If you’re a marathon runner seeking a highly cushioned and propulsive ride with exceptional stability, the Nike AlphaFly Next% might be the ideal choice.

However, if you’re drawn to the innovative EnergyRods technology, the slightly lower price point, and the potential for enhanced energy return, the Adidas Adizero Prime X could be the better option.

Ultimately, trying both shoes on and assessing their fit, feel, and performance for your individual running style and goals will help you make the most informed decision.
