Nike Alphafly 3 vs Nike Vaporfly 3

The Nike Vaporfly 3 and the Nike Alphafly 3 are two premium racing flats, each catering to different types of runners and race distances, and your choice will depend on your priorities. The Vaporfly 3 is lighter, more agile, and provides a firmer ride, making it a strong choice for shorter-distance races up to the half marathon. It also has a lower stack height. However, the Alphafly 3 has somewhat better energy return and lateral stability, making it better suited for marathon racing. It is more cushioned, which can help absorb impact, especially in the later miles of a race. While the Vaporfly 3 is more snappy for shorter distances, the Alphafly 3 is designed to optimize efficiency over 26.2 miles, making it the preferred option for marathon specialists.
