The Neo Zen 2 is Mizuno's high-stack daily trainer, rebuilt around a nitrogen-infused ENERZY NXT EVA midsole for a controlled, protective ride. The switch from the original's TPU foam to EVA trades some outright bounce for a firmer, more stable underfoot feel, backed by a wider platform and moderate rocker geometry.
An updated knit, sock-like upper wraps the foot securely for a locked-in, snug fit, with a smaller midsole cutout than the previous version for added stability.
