The Nike Alphafly 3 Review & Lab Test of 2026

The Nike Alphafly 3 is a high-performance marathon supershoe designed for serious runners. With a focus on energy return, it features an ultra-responsive foam and a carbon-fiber plate that enhance propulsion. Lab measurements indicate a notable arch fit, making this shoe ideal for those seeking peak performance during long-distance events.

The integration of a new upper with a continuous midsole contributes to its overall stability. Additionally, the verified data from our testing showcases how the design elements work together to deliver a reliable running experience. While it comes at a price of $285, the performance benefits may justify the investment for dedicated athletes.
