Our Verdict
Saucony Endorphin Speed 4
Mizuno Neo Vista
The Saucony Endorphin Speed 4 and the Mizuno Neo Vista are both plated trainers but excel in different areas. The Saucony is a lighter, more responsive super trainer, better suited for picking up the pace and racing shorter distances, making it a great option for workouts, intervals, or even competitive events. The Mizuno, on the other hand, is a plated premium trainer that provides a more cushioned, comfortable experience with greater protection, which is ideal for runners seeking plushness on recovery runs.
