Saucony Triumph iSO 5 Performance Review

I used to hate running when I’m young. I started to run from Oct., 2018. In the beginning, I chose the running shoes by its appearance. But then I find that the running shoes will affect your running status. A pair of suitable running shoes will improve your running speed and release the pressure to knees. After testing Saucony Triumph iSO 5, I’m very satisfied at it.


I choose the black and yellow colorway of Saucony Triumph iSO 5. I don’t like this colorway. But after trying, I’m very pleased to find that my foot looks smaller.

It looks heavy, but actually not. It’s light after wearing. And the mesh vamp has good air permeability.

After fastening the shoe laces, the vamp fit the foot very well.

It uses ventilated resilient shoe-pad. The insole technology also adds with FORMFIT technology to improve the comfort level. The three-deckers offer excellent comfortable running experience to the runners.

The color of outsole looks shining. The sole is durable and wear-resisting. The great traction performance is suitable to run in kinds of ground.

If your weight is heavy, you don’t need to worry that it can’t undertake your weight. It will give you perfect resilient feedback.


Saucony Triumph iSO 5 is wide shoe type. My foot is fast and the instep is high. But it’s comfortable to wear it. It won’t press my foot.

The insole is not very soft. It has great resilient feedback.

To judge if it’s a good pair of shoes, not matter if it’s good looking or it has great technology, if it’s not comfortable, it’s not a good pair of shoes.

The first time when I wear Saucony Triumph iSO 5, it’s very comfortable and easier for me to run. I can feel the great feedback from insole. As per the advertisement, the runner can feel 83% energy feedback on each step.

After running about 10km, the shoes fit the foot well and it hasn’t grinded the foot. And the air permeability of forefoot is good. The biggest advantage is the great cushion and resilient feedback. A nice pair of running shoes can improve the running speed, stabilize your kinstate and let you running easier.
