The Mizuno Neo Zen 2, brings a new addition to the Neo Zen lineup. It delivers some minor tweaks in the midsole, and overall construction of the shoe. Meanwhile, we have a complete overhaul of the upper. While I did not try the original Neo Zen, the shoe delivered exactly what I was expecting from a dynamic but reliable daily trainer. Perhaps one of my favourite shoes of 2025 for this reason, it delivers what it promises all in a very accessible package.
I took this with me throughout my winter months in all conditions from snow, to sun, to rain. I pushed the envelope hard and now have over 200km in the shoe, so let’s dig in and take a look at what I enjoyed, and the small caveats I had with this shoe.
Upper and Fit of the Mizuno Neo Zen 2
What works for me
The upper on the Neo Zen 2 has seen a nice update from the previous knitted version. It now uses a dual-layer material combining an engineered mesh with a comfortable, sock-like construction around the tongue. It keeps things lightweight and breathable, which I really appreciate. But the absolute standout feature for me is a small silicone insert placed on the dorsum of the foot, right under the laces. I’ve struggled with lace bite and rubbing in other shoes, and this little insert completely eliminates that issue for me.
What doesn’t work for me
When it comes to the fit, the shoe runs a little long for my liking. The toe box is nice and wide, which suits my foot well, but the overall length is definitely on the generous side for my standard size. If you have narrower feet, I would maybe recommend considering a half-size down, especially if you are a fan of a snug fit. I think there’s very little otherwise I don’t like about the upper, its a standard mesh which has great breathability and also a comfortable lockdown.
Midsole and Ride of the Neo Zen 2
What works for me
This is where the shoe won me over. The midsole utilizes Mizuno’s Enerzy NXT foam (a nitrogen-infused EVA), and the resulting ride is incredibly soft and bouncy. I was pleasantly surprised by how dynamic it felt; the bounce genuinely gave me vibes of top-tier foams like those found in the Evo SL or Mach 5.
The ride is very neutral and versatile enough to handle almost anything I threw at it. From easy, slower recovery days to track sessions dropping down to sub-3 minute/km pace, the midsole performed beautifully. It reminds me of the old-school Nike Pegasus lineup, giving that kind of one-stop-shop kind of vibe.
What doesn’t work for me
For a shoe that boasts 40.5mm of foam, while sitting on a relatively neutral/narrow footbed, there is always bound to be a little bit of stability drawback. I didn’t find it a huge issue while running, but once or twice (especially in the snow) I did roll my ankle in it. I don’t think it is anywhere near as bad as some other shoes, but worth keeping in mind for those who pronate heavily, especially as the heel collar is not extremely rigid like in some stability shoes.
Outsole of the Mizuno Neo Zen 2
Grip and Traction
The outsole is unfortunately the weakest link of the Neo Zen 2. It uses a very classic, standard rubber compound that just doesn’t provide the best grip. Even when running on dry, smooth stone, I found the traction to be lacking a little bit. When taking it to a wet track, the grip just did not really compare to some more recent models I have been testing. If you run in slick or rainy conditions frequently, this might be a noticeable issue, but it’s not something that has presented a huge issue for me when reaching for this shoe.
Durability
If the grip is my biggest con, the durability is a massive pro. I’ve logged between 200 and 300 kilometers in my pair so far, and the rubber compound shows almost no wear. Same goes for the midsole with the thick layer of Enerzy NXT foam. I found that it remains relatively equally as lively or supportive as before and has not “worn-out” like some other softer foams (lightstrike pro) quickly do. This shoe looks and feels like it will easily stand the test of time.
Conclusion
Value for Money
Priced at €150 / $160, the Neo Zen 2 is right on par with the rest of the daily trainer market. Considering how dynamic and versatile the shoe is (capable of handling both easy recovery miles and hard workout days) the value for money here is exceptional. I continually find myself reaching for this shoe over my more expensive options because it is a very enjoyable and dynamic ride that I can use for so much of my training.
Fitting it into a shoe rotation
This shoe is the definition of a dependable daily trainer. It handles everyday junk miles with ease, but its bouncy foam allows it to seamlessly transition into uptempo work as well. Its use case really only stops when you reach race day, where you might want something with a plate or extra propulsion. If you are looking for a minimalist rotation and want one shoe that can do almost everything, this is a perfect choice.
Final Verdict
The Mizuno Neo Zen 2 is a highly reliable daily trainer that delivers a surprisingly fun, bouncy, and versatile ride. While the wet traction is disappointing and the narrow heel sacrifices some stability, the comfort and durability of the Enerzy NXT foam make it an outstanding choice for logging miles. It punches above its weight class and serves as a great do-it-all option for the bulk of your training.
Comparisons Against Similar Shoes
Mizuno Neo Zen 2 vs. On Cloudmonster 3 Hyper
I’ve recently been testing the On Cloudmonster Hyper 3, which sits at a significantly higher price point and is marketed as a high-performance “hyper” shoe. Despite this, I actually prefer the Mizuno. The Neo Zen 2 delivers a bouncier ride, feels lighter on the foot, and ultimately offers much better value for money.
Mizuno Neo Zen 2 vs. adidas Evo SL
While the Evo SL is known for having a top-of-the-line foam, the Enerzy nxt compound in the Neo Zen 2 holds its own beautifully. The soft, dynamic bounce of the Mizuno genuinely gave me similar vibes to those premium tier midsoles, making it a very capable competitor for daily miles and uptempo work alike.
Mizuno Neo Zen 2 vs. Nike Pegasus 36
If you miss the days when the Nike Pegasus was the ultimate “one-stop-shop” for runners, the Neo Zen 2 captures that exact spirit. It has that same neutral, do-it-all construction that can handle slow days and track sessions effortlessly, but modernized with a much bouncier, higher-stacked foam.
