The Saucony Omni ISO and the Brooks Adrenaline GTS 18 are stability running shoes for runners who moderately to severely overpronate.

ADVERTISEMENTS

The uppers of the Saucony Omni ISO The preceding link takes you to Amazon.com and the Brooks Adrenaline GTS 18 differ quite a bit in what they provide to runners.

The upper of the Adrenaline GTS 18 The preceding link takes you to Amazon.com tends to be geared more towards comfort, while the Saucony Omni ISO is focused on delivering support through its upper.

The upper of the Brooks Adrenaline GTS 18 is quite open and free from overlays from midfoot to forefoot to provide lots of comfort in the toe box.

Most of the support that the Brooks Adrenaline GTS 18 delivers is concentrated halfway from the midfoot towards the heel, where it has no-sew overlays to provide support.

The Saucony Omni ISO is different in that it covers a large part of the midfoot with overlays that are integrated into the saddle to be able to be customized.

Then at the back, the Saucony Omni ISO comes with a sturdy external heel counter that prevents heel rotation and starts pronation control from within the upper.

The toe box of the Saucony Omni ISO is quite open and free from overlays, because it uses engineered mesh to provide structure and support.

While the bunion window of the Saucony Omni ISO is not as open as that of the Brooks Adrenaline GTS 18, the overlays have been pulled back and circled around the bunion window to provide room.

All in all, while the Brooks Adrenaline GTS 18 does deliver a good amount of support around the heel, it is surpassed by the amount of support delivered by the Saucony Omni ISO in that area and around the midfoot. The Brooks Adrenaline GTS 18 excels in delivering lots of comfort in the toe box, though.

The midsoles of the Brooks Adrenaline GTS 18 and the Saucony Omni ISO display some similarities.

While the Brooks Adrenaline GTS 18 is not a running shoe that is meant to deliver a very soft ride, lab tests have found that it is an overall cushy running shoe for both men and women.

The Saucony Omni ISO, on the other hand, is meant to deliver a plush ride to overpronators, but lab tests have found that while it has a cushy forefoot, its amount of heel cushioning is more on the moderate side.

Therefore, the Brooks Adrenaline GTS 18 would deliver an overall softer ride than the Saucony Omni ISO.

However, your ride should still feel overall soft in the Saucony Omni ISO but not as soft as in the Brooks Adrenaline GTS 18.

The Saucony Omni ISO comes with a topsole construction of EVERUN cushioning that is meant to deliver heel-to-toe softness as well as return energy.

Lab tests have found that the Saucony Omni ISO is fairly high in energy return, which means that your ride should feel springy in the Saucony Omni ISO.

Both the Brooks Adrenaline GTS 18 and the Saucony Omni ISO are meant to deliver lots of stability and support to overpronators and do so by having a medial post that controls pronation and helps stop your feet from rolling too far inward.

The medial post is long and runs high in both running shoes, but it seems to be a bit longer in the Brooks Adrenaline GTS 18 than in the Saucony Omni ISO.

However, this might just be optical due to the fact that the medial post of the Brooks Adrenaline GTS 18 is backed by other densities of foam that help make the process of pronation control more gradual.

The Brooks Adrenaline GTS 18 does not provide full ground contact on the medial side, because it has a small midfoot shank on that side to reinforce the medial post.

The full ground contact delivered by the Saucony Omni ISO increases its stability a bit.

However, the midsole of the Saucony Omni ISO is segmented on the lateral side but not as well segmented as that of the Brooks Adrenaline GTS 18, which more or less acts as a crash pad, which in turn increases stability.

Because the Saucony Omni ISO has an external heel counter in its upper that starts the process of pronation control and the Brooks Adrenaline GTS 18 does not, when you combine the external heel counter with the medial post in the Saucony Omni ISO and set this against the medial post and midfoot shank of the Brooks Adrenaline GTS 18, the Saucony Omni ISO and the Brooks Adrenaline GTS 18 might be on a similar level of pronation control, with the Saucony Omni ISO having a slight edge on the Brooks Adrenaline GTS 18.

The rubber outsoles of the Brooks Adrenaline GTS 18 and the Saucony Omni ISO differ in that the Brooks Adrenaline GTS 18 displays more separation and segmentation in its outsole, all of which are good for shock absorption and dissipation and for giving you a smoother ride.

The Saucony Omni ISO has a good amount of flex grooves and more flex grooves than the Brooks Adrenaline GTS 18 in its forefoot, but because it delivers so much forefoot cushioning, it turns out to be a stiff running shoe for both men and women.

The Brooks Adrenaline GTS 18 also delivers a good amount of forefoot cushioning and has also been found to be on the stiff side for both men and women.

The Saucony Omni ISO is heavier than the Brooks Adrenaline GTS 18 for both men and women.

If you are a moderate to severe overpronator who is looking for lots of stability and support, you could turn to either the Brooks Adrenaline GTS 18 or the Saucony Omni ISO.

The Brooks Adrenaline GTS 18 is more geared towards providing comfort through its upper and support through its midsole with an overall soft and smooth ride.

The Saucony Omni ISO is geared towards delivering support through both its upper and its midsole, and it can also give you an overall soft and smooth ride, but your ride might be a bit softer and smoother in the Brooks Adrenaline GTS 18.
