Saucony Omni ISO vs. Saucony Guide ISO review

Saucony Omni ISO delivers lots of stability and support to moderate to severe overpronators. Saucony Guide ISO does the same for mild to moderate overpronators in a lighter package.

The Saucony Omni ISO and the Saucony Guide ISO fall in the same category of stability running shoes, but whereas the Saucony Guide ISO is for mild to moderate overpronators, the Saucony Omni ISO is for moderate to severe overpronators.

ADVERTISEMENTS

The uppers of the Saucony Omni ISO and the Saucony Guide ISO The preceding link takes you to Amazon.com are similar in that both have ISOFIT.

However, the overlays around the midfoot are a bit thicker and cover a larger area on the Saucony Omni ISO The preceding link takes you to Amazon.com than on the Saucony Guide ISO.

They also fan out from the saddle towards the midsole to provide a more secure fit.

The Saucony Guide ISO has overlays running along the upper edge of the midsole in the forefoot and partially on the toe box itself.

The Saucony Omni ISO has engineered mesh that does not require it to have overlays on the toe box, and it does not have overlays running along the upper edge of the midsole in the forefoot, although the overlay that wraps the midfoot does come forward a bit.

However, both running shoes have a bunion window that is quite open so should be able to provide comfort to those with big bunions.

Nonetheless, the Saucony Omni ISO might deliver a bit more comfort in the toe box than the Saucony Guide ISO.

Another difference can be found at the back of the running shoes, where the Saucony Guide ISO has mainly overlays as extra support behind the heel and the Saucony Omni ISO has an external heel counter to lock the heel in.

All in all, the Saucony Omni ISO delivers a bit more support through its upper than the Saucony Guide ISO, which is in line with the kind of support that these two running shoes are expected to deliver.

The midsoles of the Saucony Guide ISO and the Saucony Omni ISO are quite similar in construction, with both having an EVERUN topsole for heel-to-toe cushioning.

Saucony lists both running shoes as delivering plush cushioning, with the Saucony Omni ISO lying two notches above the Saucony Guide ISO.

Lab tests have found the Saucony Guide ISO to have a cushy forefoot for both men and women but a heel that could feel a bit firm to some runners.

The Saucony Omni generally has a very cushy forefoot with heel cushioning that is more on the moderate side but still enough to make the running shoe feel overall cushy.

Both the Saucony Omni ISO and the Saucony Guide ISO come with a post on the medial side to control overpronation, but whereas the post of the Saucony Guide ISO is more centered under the midfoot, the one of the Saucony Omni ISO is a tiny bit longer towards the back so gives more heel support.

Saucony lists the Saucony Guide ISO at the top end of light stability, while the Saucony Omni ISO is placed at the top end of stability, close to motion control.

Therefore, the Saucony Omni ISO is expected to deliver a bit more pronation control than the Saucony Guide ISO, which is also in line with what tests generally find.

While the outsoles of the two running shoes have a zigzag pattern in their forefeet, the flex grooves run differently; they are interrupted by rubber in the middle under the Saucony Omni ISO and on two vertical locations under the Saucony Guide ISO.

Such a setup can add stiffness to a running shoe, and lab tests have found the Saucony Guide ISO to be on the stiff side.

The Saucony Omni is generally also a stiff running shoe, but a bit of stiffness also generally adds more support to a running shoe.

The two running shoes look a bit different under the medial post, with the rubber being a little bit wider under the Saucony Omni ISO, but both running shoes are well-segmented under the heel.

Both the Saucony Guide ISO and the Saucony Omni ISO provide a good amount of ground contact, which should not only add to the stability of the running shoes but also help you achieve smoother heel-to-toe transitions.

The women's version of the Saucony Guide ISO weighs approximately 8.9 oz (253 grams), while the Saucony Omni ISO for women weighs approximately 9.5 oz (269 grams).

The men's version of the Saucony Guide ISO weighs about 10.5 oz (298 grams), and the Saucony Omni ISO for men weighs about 10.7 oz (303 grams).

If you are a mild to moderate overpronator, the Saucony Guide ISO was created with your needs in mind, and if you are a moderate to severe overpronator, you might want to look into the Saucony Omni ISO.

The Saucony Omni ISO is also a good running shoe for heavier runners and runners who need tons of stability and support but do not require a motion control running shoe.

Note: The weight of a running shoe depends on the size of the running shoe, so any weights mentioned in this review may differ from the weight of the running shoe you choose to wear. Running shoes of the same size were compared for this review.
