It feels like it’s been a long time since Mizuno re-entered the conversation as a true running stalwart—but in reality, it’s only been a few years. The brand never disappeared, but there was a stretch where its identity felt a little stuck in neutral.
That changed in a big way when Mizuno’s now-famed “Mystery Shoe” started popping up on running Instagram feeds in 2024. The bold black-and-white geometric design sparked curiosity, conversation, and plenty of speculation—before finally revealing itself as the Mizuno Neo Zen.

That shoe marked a clear break from “old Mizuno” and a confident step into something more modern, playful, and forward-thinking. Since then, you’ve probably seen the Mystery Shoe pop up again as one of the more anticipated recent releases in the running space. Now, the evolution continues with the arrival of the Neo Zen 2.
Looks:
I’m really liking what Mizuno has been doing lately from a visual standpoint, especially the way their recent releases share a cohesive color story. The primarily white base with blue and green accents shows up here just like it did on the Hyperwarp Pure, giving the lineup a connected, intentional feel. If this style works for you (it does for me), it makes getting dressed a little easier and your running shoe closet a lot more consistent.
That said, fear not if white shoes are a non-starter in the PNW. The Neo Zen 2 comes in three additional colorways, including a unique and surprisingly fun pale khaki option that should hold up a bit better when conditions get less…Pacific Northwesty.
The heel collar, complete with its pull tab, is… well… long. I’m not entirely sure why Mizuno felt the need to stretch it out this much, and while it doesn’t affect performance or comfort in any meaningful way, it does look a little strange once you notice it. Thankfully, it’s more of a visual quirk than anything else—and one you’ll probably stop thinking about once you’re actually running.
Construction & Fit:
The Neo Zen originally debuted as Mizuno’s “Mystery Shoe”, complete with pre-launch teasers and unconventional visuals, before revealing itself as the Neo Zen: a bouncy, modern trainer that felt decidedly un-Mizuno in the best possible way.
The Neo Zen 2 doesn’t stray far from that formula, but it does make a handful of meaningful tweaks to round things out. It’s lighter by about half an ounce, and while the drop remains the same, there’s an additional 1 mm of stack added front and back. Mizuno also updated the upper, along with changes to the construction and composition of the midsole—adjustments that subtly shift how the shoe feels underfoot, which we’ll dig into below.
Specs:
The upper construction has been reworked and immediately feels more dialed-in than the original. The tongue is attached directly to the upper (so it’s not gusseted), but it doesn’t really need to be—the material naturally hugs the foot and stays centered without fuss. There isn’t a ton of padding on the tongue itself, but there’s a generous amount of cushion in the heel that wraps comfortably around the ankles. The result is a secure, confidence-inspiring hold that’s very much in line with other shoes in this category—locked in without feeling like your foot is being vacuum-sealed.
For me, this feels like a clear upgrade over the first Neo Zen. In my original review, I noted that the shoe felt a bit less stable overall, which I partly attributed to an upper that was just a touch too roomy. With a fairly standard foot shape, I don’t need an ultra-race fit or a wide, sloppy one—and the Neo Zen 2 lands right in that sweet spot. The fit here feels more intentional and more controlled underfoot.
That said, I can see how this might verge on too much hold for some runners. I don’t mind a snug fit—and for many, it’s a must-have—but this is right up near that line. It’s extremely secure (though does seem to loosen up a tiny bit over time), and I wouldn’t be surprised if some runners wished it were dialed back just a hair. Know your preferences and, if possible, take these for a spin. Personally, I had no issues, but fit tolerance is always a personal thing.
Midsole:
As mentioned earlier, the original Neo Zen was generally very well received—and I liked it quite a bit—but there were a few things I noticed over time. Stability felt a little dicey compared to some peers, though not to the point of being completely unusable. I ran a solid half marathon in the original without tipping over or feeling unsafe, but at my size (6’2″, ~200 lbs), stability tends to show up differently for me than it might for lighter or more “average-sized” runners.
The Neo Zen 2 seems to address that for me in a noticeable way. It feels considerably more stable overall, which I’d attribute to a combination of the more secure upper (previously discussed) and the updated midsole geometry and foam.
I know there are runners who loved the high-energy bounce of the original Enerzy NXT setup, especially given that most supercritical foams push trainers closer to the $200 mark. Having a similar kind of foam in a more affordable shoe was part of what made the original Neo Zen feel special. So yes—moving from a supercritical TPU to a supercritical EVA is a change that some people may immediately side-eye.
Personally, though, this change worked better for me. Bouncier foams can be a bit more challenging under a larger frame, and while the Neo Zen 2 still offers plenty of cushioning—arguably even more in the forefoot—it doesn’t feel as bouncy overall. The result is a ride that feels less like a middle-distance performance shoe (which is where the original Neo Zen ultimately landed for me) and more like an accessible daily trainer. That makes this version being reached for far more often than I ever did with the original. It may not feel quite as speed-driven, but for my running, it’s a change I genuinely prefer.
Outsole:
The outsole here is fairly standard as far as road shoes go. Grip has been perfectly adequate in real-world use, though even a quick thumb test makes it clear this isn’t the grippiest rubber compound out there. Coverage is solid overall, with enough outsole rubber to protect high-wear areas while still leaving some midsole exposed to keep weight in check.
With the midsole shift from TPU to EVA, there’s a reasonable question about long-term durability, as TPU typically holds up a bit better over time. That said, based on early mileage and wear patterns, we’d still expect the Neo Zen 2 to handle daily training duties just fine without any major concerns.
Overall:
The Mizuno Neo Zen is an impressive addition to the daily trainer lineup. While fans of the Mizuno Vista might miss the plate, the Zen’s focus on cushioning and responsiveness makes it a standout on its own. At a price point of $150, it delivers exceptional value for a shoe that feels as luxurious as some of its pricier competitors.
If you are looking for a versatile, comfortable trainer that doesn’t break the bank, the Neo Zen is worth a try. It’s a shoe that finds harmony between performance and affordability. Mizuno is on to something here.
