Without a doubt, the biggest update sits underfoot. The Neo Vista 2 now features a dual-layer midsole setup: the familiar ENERZY nxt foam from the original sits on the bottom, while the top layer borrows the nitrogen-infused foam from Mizuno’s bouncy Neo Zen.
For those who haven’t run in the Mizuno Neo Zen, let me tell you it’s an explosively energetic shoe. Bringing that top-layer feel into the Neo Vista 2 creates a noticeably more responsive, lively ride. On long runs, it still soaks up kilometres effortlessly, but now it also feels comfortable when you dial up the pace. I’ve been able to drop down to low 4 min/km splits, something I’d never have attempted in the original Vista, which was firmly a long-run-only companion.

That said, the shoe still isn’t a dedicated speed or tempo trainer — but it’s inching closer to models like the ASICS Superblast, expanding its versatility beyond slow, easy miles. Importantly, the slightly firmer setup (compared to version one) improves midsole stability, though with such a tall stack, I’d still caution stability-seekers to look elsewhere.

The embedded fibreglass plate remains, giving just the right amount of snap without making the ride harsh or aggressive. Combined with Mizuno’s excellent Smooth Speed Assist rocker geometry, the shoe offers a fluid, rolling transition that makes it feel almost effortless to keep your legs turning over.
