Mizuno Wave Inspire 15 Review

Mizuno has updated the Wave Inspire with an upper change for 2019. What’s new with the Wave Inspire 15? Let’s find out!

Mizuno Wave Inspire 15 vs Wave Inspire 14

The Wave Inspire 15 doesn’t deviate much from the 14, but the upper does have some slight tweaks that might make the transition a little better. Overall, Mizuno hasn’t messed with their well-received Inspire 14.

  • Weight is almost identical – and any differences would be so small that you wouldn’t be able to notice it on-foot
  • No changes to the midsole or outsole
  • The upper is a little more flexible and more breathable, and it might make the overall transition of the shoe a little smoother
  • Those who liked the Inspire 14 will have nothing to complain about with this update!

Mizuno Wave Inspire Review


The Wave Inspire 15 provides a pretty narrow fit through the heel and midfoot. The toebox is on the narrow side, but a much more flexible and forgiving upper still gives some room runners with a wider forefoot. The fit of the Inspire 15 maintains the shoe’s streamlined feel overall and should address most concerns for heel slippage.


Mizuno’s recent trend towards plush shoes marches on, with the Wave Inspire 15 keeping the nice soft ride that the 14 introduced. Mizuno has done a great job in making the ride of the shoe soft and light while still maintaining the stability and durability of the wave plate. Both the underfoot plushness and the step-in feel of the Inspire 15 make it feel like a premium shoe. Compared to its mild-guidance competitors, the Inspire 15 is one of the softest, plushest options available. It also makes it one of the least performance-feeling shoes in the field.


The Mizuno Wave Inspire 15 maintains the amount of mild-pronation correction found in previous Inspires. It can be used by runners who need and desire a slight amount of guidance, while also being appropriate for neutral runners who don’t have any lateral bias as well as those who may pronate considerably but don’t feel comfortable in more beefy stability shoes.


Mizuno Wave Inspire vs Wave Rider: The Inspire and Rider are designed with a different runners in mind – with the Wave Rider being designed as a standard-weight trainer for neutral runners who don’t pronate and the Inspire designed to prevent pronation for runners with some flexibility in their gate. Fit is similar on each shoe, with the Inspire maybe having a little more room in the toebox or at least having a slightly more flexible upper. There is a surprising difference in the feel of the shoes – with the Rider having a much higher-feeling heel and riding a little softer in the heel (but with a pretty similar forefoot experience.) Function is the biggest difference between the shoes, with the Inspire having a pretty good amount of support for runners who pronate and the Rider lacking that guidance.

Mizuno Wave Inspire vs Asics GT 2000: The Wave Inspire 15 feels higher and softer than the 2000, while the 2000 feels much faster/performance based. The amount of guidance is pretty similar, with the 2000 maybe having a small amount more support (but in terms of real-world performance, the two should be considered the same). The 2000 is a wider in the heel and midfoot, but could be up to half a size smaller (and feels that specifically because of a really shallow toebox). The weight is identical, but the Inspire feels a little heavier on the foot due to the more performance-feel of the 2000s.

Mizuno Wave Inspire vs Brooks Adrenaline GTS: The Wave Inspire 15 feels relatively similar to the Adrenaline GTS 19. It’s a little lower than the Adrenaline, but might feel very slightly softer. The Adrenaline is wider, especially in the forefoot – but you have a little more toeobx depth in the Inspire. The big change in the Adrenaline 19 means that it’s hard to directly compare stability as Brooks is now basing stability from a more holistic perspective rather than merely focusing on the ankle, but from what we’ve seen with the Adrenaline and Inspire so far, they are pretty comparable guidance-wise. The Inspire 15 is no longer heavier than the Adrenaline GTS 19, going from a noticeable ounce heavier in previous generations to a not-as-noticeable .8 oz difference in favor of the Inspire.

Mizuno Wave Inspire vs ASICS GEL Kayano: The Inspire 15 is about as soft as the Kayano, but the two shoeshave a pretty different overall experience. You feel a little higher in the Kayano, but that doesn’t directly translate into a softer ride. ASICS has really improved the transition on the Kayano so that it doesn’t provide such a solid boot-like feel on heel strike, but you still feel like the Kayano is a little more of a solid platform.  The Kayano 25 is heavier and feels heavier on your foot, but also provides much more guidance for those with a tendency to roll in. The Inspire is much narrower throughout the shoe, but toebox depth is about the same.
