Our Verdict

ASICS NOVABLAST 5

Mizuno Neo Zen

The Mizuno Neo Zen and the ASICS NOVABLAST 5 are both modern, high-stack daily trainers built for comfort and bounce, but they differ in execution. The Mizuno is softer and more cushioned, offering a plush, highly protective ride that's ideal for easy and recovery runs. It also features a sock-like upper that helps save weight and contributes to the shoe's lighter overall build compared to the ASICS. However, this upper comes with a tradeoff—the lockdown isn't as secure, and it has a less accommodating fit that can feel more unstable during longer runs.
