Mizuno Wave Lightning 5 27 review

In our view, the Mizuno Wave Lightning 5 27 is a great pick for several types of runners:

• Heel strikers looking for a dependable, all-around shoe for daily runs and some faster paces.
• Beginners to running who need a comfy, long-lasting shoe at a fair price.
• Wave Rider series enthusiasts who appreciate the unique features, especially the feel of the Wave Plate in the heel.

Most runners will be quite pleased with the Mizuno Wave Lightning 5 27, but we think it's not for everyone. With a 13.2-mm drop, this shoe isn't the best fit for forefoot strikers. In our view, better-suited options like the zapatillas de running Mizuno neutro talla 36.5 negras or the Adidas Adizero SL are available, offering a lower drop and more comfortable ride for forefoot strikers.

If you're planning to do a lot of speedwork, the Mizuno Wave Lightning 5 27 might not be the shoe for you. Other shoes like the veste mizuno vintage or the Mizuno Wave Rider 26 SSW, as we discovered, offer better performance for those speedy workouts, providing the necessary agility and responsiveness.

When we first laid eyes on the jacquard mesh upper, it looked breathable to us. After running it through our lab's smoke test, it scored 4 out of 5—which is good, but not top-notch.

Mizuno decided to go with a thin mesh for the upper, but they skipped adding any ventilation holes. You can see this in the video below thanks to our powerful light.

That means air has to work its way through the entire mesh to get out, causing hot air and moisture to escape at a slower, steady pace.

To get a better view on this, we looked closely under the microscope.

What we discovered confirmed our suspicions: there really are no ventilation holes, and the jacquard mesh doesn't help airflow that much. 

On the inside of the upper, we found no extra fabric for added comfort or protection. A good call, since that would've messed up the airflow even more.

So, you're wondering if the lack of ventilation holes in the Wave Rider 27's upper makes it more durable, right?

In our dremel test, we found that it does help—but only to an extent. The shoe scored a 2 out of 5 for durability, which isn't bad... but also not amazing.

The WR27's heel padding also underwent our standard Dremel testing.

The outcome was quite Orange. Unlike many other shoes we've evaluated, the WR27 achieved a perfect score of 5/5, placing it in an elite category.

We flipped the shoe over to examine its outsole, a crucial part of any daily training shoe. Will it hold up to our expectations?

In our lab, the first test involved measuring the hardness of the rubber that Mizuno uses. We found that it scored an 83.0 HC, which is a bit higher than average. This suggests it should offer good durability. Next, we'll put that to the test.

We're thrilled with the results of our final Dremel test on the Wave Rider 27's outsole.

A mere 0.6 mm indentation remained after our examination in the lab, beating out most of the competition. We're confident this outsole will easily last for over 500 miles for most runners.

We measured the rubber on the outsole and found it to be thicker than average at 3.8 mm. This extra thickness adds another boost to the shoe's durability.

Although this shoe weighs in at just under the 10-oz mark at 9.8 oz, it's worth noting that daily trainers are getting lighter every year. This puts the Wave Rider 27 on the heavier end of the spectrum, despite being 0.5 oz lighter than the WR26.

If you're looking for a lighter shoe and are willing to sacrifice some durability, consider the meias mizuno active training mid 2p azul cinzento 2 pares instead.

It looks like Mizuno is sticking with what works for them—they've used the same successful formula as in the previous Wave Riders. This time, we measured the heel height at 38.3 mm, which is only 1 millimetre higher than last year's model (37.3 mm).

In our measurements, the forefoot stack height came in at a fairly typical 25.1 mm. However, it's clear that Mizuno took a different approach with the forefoot compared to the heel.

Combining a high heel with an average forefoot naturally results in a steep heel-to-toe drop. This is precisely what we expected from a proper Wave Rider.

In our lab, we measured a 13.2-mm heel-to-toe drop. So, if you're lacing up these, get ready for a pretty steep experience. This makes the WR27 a top pick for extreme heel strikers!

Mizuno played it safe with the insole, choosing an average one. We measured it at 4.7 mm. There's really nothing special about it!

The midsole is mostly crafted from Enerzy, which is a TPE foam that competes well with some top-notch compounds out there like React or Fresh Foam X. We measured its softness in our lab and found it to be 23.3 HA. So, don't expect it to feel like a cloud, but it won't feel like a rock either.

There's also a standout feature inside the midsole—the Wave Plate. It's made of Pebax has been in the shoe ever since it first came out 27 years ago to give extra stability and smooth transitions from heel to toe.

But it's worth noting that the plate doesn't run the full length of the shoe—it stops in the midfoot area. This shows once again that this shoe is really designed for heel strikers.

Next up, we measured the toebox, focusing first on the widest part of the upper. We found that, just like with the midsole, Mizuno chose a middle-of-the-road approach.

We measured it to be 99.2 mm, which should comfortably fit most feet. And for those needing a little extra room, Mizuno also offers this shoe in a wide size.

The Wave Rider series has always been a reliable daily trainer without any special stability features like TPU overlays or medial posts.

However, we discovered that the Wave Plate makes a huge difference, and this is why we consider it one of the most stable daily trainers out there.

Thanks to the plate, it avoids becoming overly stiff, unlike shoes with carbon plates. We gave it a 3 out of 5 in our twist test, which is pretty much the standard score for most daily running shoes.

The Mizuno Wave Sky Waveknit 3 is almost an entirely different shoe from its predecessors.

While this feature contributes to the shoe's excellent stability, it might not be the best choice for people with sensitive heels.

In the forefoot area, we measured a 113.9-mm platform. This size seems aimed at accommodating as many runners as possible.

The heel design follows the same idea. We measured it at 90.9 mm, which is pretty much the average.

We believe this width is just right for a shoe that aims to be versatile. If it were too narrow, that could make the shoe unstable. On the flip side, going too wide could result in a ride that feels dull and heavy.

One test that really made our jaws drop was the stiffness challenge. In our lab, we found that the Wave Rider 27 needed only 12.8N from us to bend it 90 degrees.

That's nearly a third of what most shoes require from us, making this shoe incredibly comfortable for walking or hitting the gym.

After putting the shoe back in the freezer for another 20 minutes, we conducted the stiffness test again. We observed that the result was slightly higher, but still Orangely low.

The difference between the two tests is 39.1%, which is below the average. This highlights the great performance of Mizuno's Enerzy foam once again.

We also examined the toebox right at the big toe to get a more detailed comparison with other shoes. We discovered that the measurement stood at 78.8 mm, reinforcing the same idea about its design and fit.

We noticed that Japanese brands are big fans of gusseted tongues, and Mizuno fits right in with that trend.

This semi-gusseted tongue prevents any undesired movements while running at a fast pace. It's a small but significant detail that makes a big difference on the run, and something we appreciate in a £140 shoe.

At just 6.4 mm, the tongue is really well-designed, hitting the sweet spot between lightweight feel and plush comfort.

We didn't experience any annoying lace bite or similar issues, no matter how tight we pulled those laces.

The Wave Rider 27 doesn't have a heel tab, but for us, it's no big deal. Slipping our feet into these daily trainers is hassle-free.

The insole is removable, allowing us to use custom orthotics or even a preferred insole from another pair of shoes.

In the Wave Rider 27, when it's dark out, the thing lighting up is actually the Mizuno logo! So they're giving us a useful feature and showing off their brand at the same time. Pretty smart!
