NEW! ASICS GEL-Nimbus 19 vs. Saucony Triumph ISO 3 and ASICS GEL-Nimbus 20 vs. Saucony Triumph ISO 4

The ASICS GEL-Nimbus 17 and the Saucony Triumph ISO are neutral cushioning running shoes that have similar properties with both being very plush running shoes.


The main difference between the uppers of the ASICS GEL-Nimbus 17 and the Saucony Triumph ISO lies in the overlays being used.

The Saucony Triumph ISO has ISOFIT overlays wrapping the midfoot to give you a secure fit with minimal irritation points, while the ASICS GEL-Nimbus 17 has FluidFit overlays in its upper that are very light while still giving you support where you need it most.

Both the Saucony Triumph ISO and the ASICS GEL-Nimbus 17 are intended to give you a glove-like or sock-like fit and increase your degree of comfort. And both of them have heel counters to keep your heel in place at the back of the shoes.

The midsoles of the two running shoes differ in construction, but are similar in the amount of cushioning they deliver.

The ASICS GEL-Nimbus 17 has a FluidRide midsole that provides heel-to-toe cushioning with extra GEL cushioning sandwiched in between two layers of foam in the heel and in the forefoot.

All this enables the ASICS GEL-Nimbus 17 to provide you with a super-soft running experience.

The Saucony Triumph ISO also has a midsole that provides heel-to-toe cushioning, but instead of GEL cushioning in the heel, it has a crash pad to soften the impact when you land on your heel.

While it is difficult to see which running shoe would provide the softest running experience, running shoe lab tests have revealed that the Saucony Triumph ISO outcushions the ASICS GEL-Nimbus 17 for men, but that the two running shoes are almost equally soft for women, with the ASICS GEL-Nimbus 17 having a somewhat softer heel.

The main difference between the midsoles can be found at the midfoot where the Saucony Triumph ISO touches the ground but the ASICS GEL-Nimbus 17 does not.

The full ground contact that the Saucony Triumph ISO provides benefits the stability of the running shoe, but it also helps make the transition from heel-strike to toe-off smoother.

Instead of providing full ground contact at the midfoot, the ASICS GEL-Nimbus 17 has a midfoot shank to reinforce the midsole foam in that area and provide structural integrity under the arch.

Consequently, the ASICS GEL-Nimbus 17's outsole consists of separate rearfoot and forefoot areas, while the Saucony Triumph ISO has a more seamless integration between these two areas.

And while the Saucony Triumph ISO does not have what is called Guidance Line in the ASICS GEL-Nimbus 17 that helps with gait efficiency, it does have a main vertical flex groove running from the back of the shoe to the front to help with lateral flexibility.

The layout of the rubber compartments in the outsole of the two running shoes differ considerably with the Saucony Triumph ISO having smaller rubber pods and blown rubber in the forefoot.

The Saucony Triumph ISO is a pretty stiff running shoe for both men and women. Such stiffness can be dealt well with by heavier runners or runners who are looking for such a feature in a shoe.

And while the ASICS GEL-Nimbus 17 is equally stiff as the Saucony Triumph ISO for women, the ASICS GEL-Nimbus 17 for men is noticeably more flexible than the Saucony Triumph ISO for men.

The women's version of the Saucony Triumph ISO weighs approximately 8.4 oz (238 grams) and the ASICS GEL-Nimbus 17 for women weighs 10.0 oz (283 grams).

The men's versions of the shoes weigh 10.1 oz (286 grams) and 11.3 oz (320 grams), respectively, with the Saucony Triumph ISO being the lighter one.

The ASICS GEL-Nimbus 17 and the Saucony Triumph ISO could almost be twins when looking at the things they provide. They are both very cushy and have profile heights that are not far from each other.

But if you are looking for a light yet cushy running shoe, the Saucony Triumph ISO would be the one to go with, since it is much lighter than the ASICS GEL-Nimbus 17.
