Our Verdict

Saucony Endorphin Pro 4

Nike Alphafly 3

The Saucony Endorphin Pro 4 and Nike Alphafly 3 are both long-distance racers, but the Saucony is the more versatile option. It offers better stability and geometry that works especially well for heel strikers, while the Nike is lighter and provides more cushioning. Get the Saucony if you want a racer that can double for workouts; get the Nike if you want the more marathon-focused shoe.
