Mizuno Wave Inspire 15 vs. Saucony Guide ISO 2 review

Mizuno Wave Inspire 15 provides an overall soft and stable ride to moderate overpronators. Saucony Guide ISO 2 provides stability, support, and a custom fit to overpronators...

The Mizuno Wave Inspire 15 and the Saucony Guide ISO 2 are stability running shoes for runners who moderately overpronate.

ADVERTISEMENTS

The uppers of the Mizuno Wave Inspire 15 The preceding link takes you to Amazon.com and the Saucony Guide ISO 2 are similar in that they have a forefoot that does not constrict much so provides lots of room and comfort to runners who have wide feet or big bunions.

The main difference between the uppers of the Saucony Guide ISO 2 The preceding link takes you to Amazon.com and the Mizuno Wave Inspire 15 is that the upper of the Saucony Guide ISO 2 can be customized through the individual eyelets in the saddle.

Another minor difference is that while both running shoes come with some no-sew overlays in their uppers, the Mizuno Wave Inspire 15 is the one that still has some stitched-on overlays.

In addition, the Mizuno Wave Inspire 15 uses the Mizuno logo to provide a good connection between the saddle and the midsole to offer additional support around the midfoot.

Both running shoes have a structure that is more closed around the heel to increase the amount of support in that area without going overboard.

The back of the heel of the Mizuno Wave Inspire 15 seems to run a bit higher than that of the Saucony Guide ISO 2, while the back of the Saucony Guide ISO 2 seems to follow the form of the heel better and give it a "cup" to sit in.

All in all, you should be able to get a good amount of comfort from the upper of either running shoe, but while the Mizuno Wave Inspire 15 is more geared towards delivering comfort in the toe box and just the right amount of support that an overpronator needs around the midfoot and the heel, the Saucony Guide ISO 2 is more concerned with providing an overall better and more custom fit.

The midsoles of the Saucony Guide ISO 2 and the Mizuno Wave Inspire 15 also display quite a few differences.

The first thing that sticks out is the device they use to deliver stability and support to overpronators.

The Mizuno Wave Inspire 15 uses a Wave plate that fans out on the medial side to increase the amount of resistance against your foot turning inward as an overpronator.

ADVERTISEMENTS

The Saucony Guide ISO 2 achieves the same goal but then with a more traditional medial post.

However, when you compare the two devices, the Wave plate covers a larger area of support from heel to midfoot than the medial post in the Saucony Guide ISO 2.

It also has an additional function of delivering midfoot support and shock absorption at heel-strike.

The medial post of the Saucony Guide ISO 2 is relatively short but runs high and covers an area that can serve most overpronators.

The amount of stability and support delivered by both running shoes is on the moderate side.

The Saucony Guide ISO 2 is meant to be a running shoe that delivers a good amount of cushioning but still feel responsive, so it does not go overboard with cushioning.

The Mizuno Wave Inspire 15 has a midsole that consists of two layers of foam, with the top one running from heel to toe and the bottom one from heel to midfoot.

The bottom layer of foam under the heel is a bit softer, which helps to increase the amount of heel cushioning in the Mizuno Wave Inspire 15.

The Saucony Guide ISO 2 comes with one main layer of foam and then it has a topsole construction with a softer layer of foam that runs from heel to toe.

It has been found that the Saucony Guide ISO 2 delivers an overall moderate amount of cushioning, with women getting a cushy forefoot, while the Mizuno Wave Inspire 15 has been found to deliver an overall soft ride with a very cushy heel to both men and women.

Therefore, the Mizuno Wave Inspire 15 might be more suitable for heel-strikers than the Saucony Guide ISO 2, and it also delivers an overall softer ride than the Saucony Guide ISO 2 to both men and women.

The Saucony Guide ISO 2 provides more ground contact than the Mizuno Wave Inspire 15, but because the heel and the forefoot of the Mizuno Wave Inspire 15 are not separated too far from each other and because the Wave plate forms a bridge between the heel and the forefoot, you can expect to get a smooth ride from either running shoe, but it might feel just a tad smoother in the Saucony Guide ISO 2.

The outsoles of the two running shoes look very different and both display a good amount of separation under the heel, which is good for shock absorption and dissipation at heel-strike.

However, the Saucony Guide ISO 2 has many more deep flex grooves in the forefoot compared to the Mizuno Wave Inspire 15, but this does not help much with adding flexibility, because both running shoes have been found to be on the stiff side for both men and women, but stiffness is a good thing for stability and support.

The Mizuno Wave Inspire 15 is just a bit lighter than the Saucony Guide ISO 2 for both men and women.

If you are a moderate overpronator who is looking for a running shoe that feels comfortable on the road, you could turn to either the Saucony Guide ISO 2 or the Mizuno Wave Inspire 15.

The Mizuno Wave Inspire 15 sticks out in that it delivers stability plus an overall soft ride, and it would be suitable for heel-strikers.

The Saucony Guide ISO 2 is more moderately cushioned compared to the Mizuno Wave Inspire 15, but the Saucony Guide ISO 2 might provide a better and more custom fit.
