The Nike Alphafly 3 is designed for runners who supinate, providing a combination of speed, cushioning, and support that facilitates the pursuit of personal bests. This elite racing shoe features advanced technologies aimed at enhancing performance on race day.
From the initial strides, the Alphafly 3 demonstrates its capabilities. The energy rebound during toe-off is significant, driven by the dynamic FlyPlate and Air Pods within the midsole. Lab tests reveal its stiffness, withstanding a force of 28.4N to bend to 30º, exceeding the average by 89.3%.
Integral to its structure is the superior ZoomX midsole, which boasts a stack height of 38.1/29.6 mm for enhanced comfort. The dual-foam setup includes an impact-absorbing layer with a hardness of 18.1 HA and a firmer layer at 29.3 HA for additional support.

The Endorphin Pro 4 is best suited for runners with a heel strike pattern who prioritize comfort and speed in their footwear.
In our test runs, the shoe features a plush midsole complemented by the carbon plate’s Speedroll technology, which delivers a smooth and energetic ride. With a weight of only 7.8 oz (220g), this light supershoe provides significant energy return thanks to its S-shaped carbon plate that creates an ultra-stiff core.
The lively midsole promotes effortless transitions while maintaining comfort. Its 38.1 mm heel is designed to absorb impact with a 9.5 mm drop that supports heel-striker strides, and it retains stability through a firmer 22.0 HA foam layer beneath the softer 18.5 HA top layer.
The durable outsole contributes to the shoe's longevity, able to withstand repetitive impacts in the rear area. Our durometer testing shows that the 2.1 mm thick XT-900 rubber has a hardness rating of 85.3 HC, indicating notable durability, and it surpasses average performance in our rigorous Dremel test.
However, it is worth noting that some elite racers may find other options more suited to achieving peak performance, as the EP4 emphasizes comfort over sheer speed.
