mizuno Scarpe Sko Wave Lightning Z6 review

Based on our tests, the mizuno Scarpe Sko Wave Lightning Z6 is an interesting option for certain types of runners:

• Midfoot strikers in search of a well-cushioned marathon racer, provided they don't require additional stability
• mizuno Scarpe aficionados eager to include the brand's top-performing racing shoe to their J2GY8551Z91
• Those ready to take on an unconventional, wild road racing shoe

For heel strikers and forefoot strikers, opting for this shoe may not be the best choice, as its benefits won't align with your running style. Instead, we suggest considering the Saucony Endorphin Pro 3 (for heel strikers) or the ASICS Metaspeed Sky+ (for forefoot strikers).

Runners seeking a reliable, risk-free option for their upcoming race might also want to bypass the mizuno Scarpe Morelia 35 Anniversary Limited Edition Legend Sport.

zapatillas de running mizuno Scarpe trail pronador tope amortiguación talla 38 grises Adidas Adizero Adios Pro 3 and Hoka Rocket X 2, provide solid performances without the specific demands of the mizuno Scarpe Morelia 35 Anniversary Limited Edition Legend Sport. These alternatives boast full-length premium midsoles and superior stability.

We expect shoes that are priced at £260 to mention excellent breathability, but the mizuno Scarpe Sko Wave Lightning Z6 disappoints us in this aspect. Our lab tests resulted in a modest 3/5 score.

This outcome was unexpected for us, emphasising the need for lab testing in running shoes. If we had only conducted the light test, we might have assumed the mizuno Scarpe Morelia 35 Anniversary Limited Edition Legend Sport was breathable—since the entire upper appeared that way. Sadly, this was not the case.

Despite the large ventilation holes we noticed under the microscope, the shoes didn't score well regarding breathability.

In fact, these holes are the reason it got a 3/5 score; otherwise, it would have received the lowest score.

Overall, it's a weird shoe that yields a weird result in this test.

And it's important to remember that, if not for the smoke test, all other signs indicated good ventilation, including the interior layer of the upper with hundreds of perforations.

While shoes with low breathability sometimes make up for it with high durability, this one does not.

After we put the mizuno Scarpe Morelia 35 Anniversary Limited Edition Legend Sport through our Dremel test, it earned a disappointing 1/5 score. If these two factors are important to you, the Nike Alphafly 2 stands out by performing 5/5 in both areas, and it's similarly priced.

Competition shoes typically do well in the heel padding durability test during our back-to-back dremel tests, as they often have minimal padding in this area.

However, the mizuno Scarpe Morelia 35 Anniversary Limited Edition Legend Sport has a lot of padding in the heel seeking comfort for long-distance races. This is why its score is lower than average at 2/5.

This shoe keeps delivering surprise after surprise.

The outsole is designed with multiple cutouts to reduce weight and enhance flexibility. mizuno Scarpe has also included more rubber coverage compared to other racing shoes in an effort to increase durability.

Racing shoes tend to have softer rubber in the outsole in an effort to maximise grip, but we measured actually the opposite! At 81.5 HC, is even harder than most running shoes, yet it offers A+ grip.

This shoe demonstrated twice the importance of conducting various tests to fully understand its features. As it happened with breathability, if we had only assessed the hardness and extensive coverage, we might have assumed this was a durable shoe. However, it's not.

Following our Dremel test, we observed a significant 2.6-mm indentation in the rubber. Essentially, one of the 262 mini-lugs vanished.

mizuno Scarpe definitely knew about this problem, and that's why they added those 2.6-mm mini-lugs, aiming to boost durability.

It's pretty clear they need to up their game for the outsole in the WRP v2. Maybe a quick trip to Adidas to snag some of that Continental rubber could do the trick!

In the heel, mizuno Scarpe opted for a slightly stiffer design compared to many racing shoes, yet it remains flexible.

Considering its instability, we believe that the stiffness rating of 2/5 that we gave the shoe is actually lower than what would be ideal.

Weighing in at just 7.5 oz or 214g, the mizuno Scarpe Sko Wave Lightning Z6 is remarkably light for its size. This is achieved by not using a solid slab of foam for the outsole.

Instead, it has several cutouts that help minimise weight but also result in less foam underfoot.

mizuno Scarpe implemented a smart strategy with this shoe. They aimed to provide as much cushioning as possible without exceeding the 40-mm limit set by World Athletics at the official heel measurement point.

To achieve this, they removed a portion of foam from the heel, ensuring compliance with regulations as our measurement came in at 38.2 mm.

However, the midfoot offers nothing less than 51 mm, making it the most cushioned yet race-day legal shoes ever produced. That's Japanese innovation!

In the forefoot, the shoe has a measurement of 33.3 mm, similar to many racing shoes, once again meeting World Athletics' standards.

And what about the drop? While the difference between the heel and the forefoot is 4.9 mm, that doesn't tell the whole story.

Examining the cross-section of the shoe reveals an unconventional geometry: instead of a gradual decline from heel to forefoot, the thickest portion of foam is situated around the midfoot.

This shoe is specifically tailored for fast runners who use a midfoot striking technique, and we can confirm it is not suitable for heel strikers and likely many forefoot strikers as well.

The insole is only 3.6 mm thick, placing it on the slimmer side. Nonetheless, we found that it feels comfortable and seems more than ready to take on the longest races!

Yes, the insole was quite standard, so let's return to the bizarre stuff.

Unlike most racing shoes that provide a single layer of bouncy foam, mizuno Scarpe chose a dual-foam setup comprising a plush foam and a brick-like foam, aiming for a balanced ride.

The first foam we assessed is mizuno Scarpe Enerzy Lite, the one closer to the ground. It's a firm (30.4 HA) TPE foam that is lightweight and durable, but it somewhat lacks energy return—one of the features we appreciate most in racing shoes.

When paying a premium price for a shoe, we expect premium foam, and unfortunately, Enerzy Lite doesn't meet the mark.

The other foam in this two-part midsole setup is Enerzy Lite+, a PEBA foam that's both soft and impressively springy. In our durometer tests, it scored a 16.0 HA measurement, and it certainly feels wonderful underfoot, offering massive energy return.

To fight with the top-tier shoes, the next version of the mizuno Scarpe Morelia 35 Anniversary Limited Edition Legend Sport should use only this foam. mizuno Scarpe just needs to slightly adjust the formulation of the layer closer to the ground to make it a tad firmer in order to boost stability.

After chilling the shoe in the freezer for 20 minutes to simulate cold conditions, we retested the Enerzy Lite's softness and recorded a durometer reading of 32.5 HA.

With only a minimal 6.9% increase, this shoe delivers an exceptional, world-class performance, ensuring that racing in cold temperatures—which is ideal for this shoe due to its limited breathability—becomes a fantastic and enjoyable experience.

With a whopping 51 mm of stack height in the midfoot, we knew that stability might be a challenge, regardless of the carbon plate and how firm one of the foam layers is.

After our testing, we found that the shoe is best suited for neutral runners who have excellent technique. It can be a bit tricky, especially when taking corners, but it also offers a unique and fun ride!

Equipped with a plate, the shoe was poised to get the top score for torsional rigidity—and indeed, it secured a score of 5/5! We could barely twist it.

In the heel, mizuno Scarpe opted for a slightly stiffer design compared to many racing shoes, yet it remains flexible.

Considering its instability, we believe that the stiffness rating of 2/5 that we gave the shoe is actually lower than what would be ideal.

In the midsole, we discovered a width typical of running shoes, aimed at ensuring a stable ride for midfoot and forefoot strikers.

This design works well, and while a wider option could have been intriguing, we recognise that the potential weight increase might have been a concern for performance.

Back in the heel, we're diving again into the eye-popping details.

With a super slim width of just 78.6 mm, it's pretty obvious that this shoe isn't meant for any heel strikers out there.

The mizuno Scarpe Sko Wave Lightning Z6 comes equipped with a plate sandwiched between the Enerzy Lite and Enerzy Lite+ foams, leading us to anticipate a high score in our stiffness test.

Surprisingly, with a result of 42.8N, it isn't exceptionally stiff, and there's a reason behind this.

Contrary to most racing shoes, the plate isn't entirely made of carbon fibre. Instead, it's a blend of 70% nylon and 30% carbon fibre. Additionally, the plate features an opening in the forefoot, further decreasing the stiffness.

After chilling the shoe in the freezer for an additional 20 minutes, we conducted the test again and found that it required 57.9N of force.

A 35.4% change is quite significant compared to other high-end racing shoes. This is definitely another aspect where mizuno Scarpe needs to improve for v2.

The desire from mizuno Scarpe to make the shoe as light as possible likely caused them to leave out the option of having a heel tab. Not a big deal, anyway.

The toe space isn't super roomy, narrowing down to just 75.2 mm at the toe cap. But let's be real, it's a racing shoe, so that's kind of what we're signing up for.

Although we haven't noticed any unwanted shifting from the tongue, its lack of gussets (full or semi) could potentially lead to a subpar experience during races or speed workouts. This is something that really shouldn't be found in a shoe with a £260 price tag.

The tongue is a mere 1.8 mm thick, aligning with expectations for racing shoes, yet it's more cushioned than many of its competitors.

The desire from mizuno Scarpe to make the shoe as light as possible likely caused them to leave out the option of having a heel tab. Not a big deal, anyway.

While some competition shoes feature glued-in insoles, the mizuno Scarpe Morelia 35 Anniversary Limited Edition Legend Sport opts for a removable one, and we appreciate it.

However, the shoe's distinctive narrow heel and wide upper indicate that many aftermarket insoles may not fit seamlessly.

There aren't any reflective elements, but honestly, who needs them for road races?
