Triumph ISO 4

The Triumph ISO 4 is pure comfort. It is very snug all around. It has terrific cushioning from heel to toe. The toe box is quite ample. In short, it is a great shoe.

These are not the shoe for heavier runners. I weight around 190 lbs. and the cushioning bottoms out when I’m running in them and produces a very harsh ride. Walking around the cushioning feels good, but a little ways into the run and the full length Everun sole compresses and produces a very unpleasant ride, I’m going to try the new Ride ISO and see how it does. I never had this issue with the Triumph ISO 3.

The Triumph ISO 3 and--and by default, Saucony--changed my life by ending 40 years of foot pain. I bought several pairs, and was excited to give the ISO 4 a try...it is just not up to snuff. The Triumph ISO 4 is clearly a quality shoe, but lacking a couple of the features that made the ISO 3 so comfortable. First, the Tri-Flex sole was incredible; it provided support, while allowing my feet frwwdom of motion. The ISO 4 sole is more stiff, less flexible, and as a result, not as comfortable or cushioned. Second, I prefer the two ISO-Fit straps of the ISO 3 rather than the three straps of the ISO 4. I have very high arches, and I have to lace the shoes looser to prevent stress on the top of my foot. The ISO 3 did not create pressure. Lastly, while I know there is more Everun, the ISO 4 just doesn't fewl as deeply cushioned as the ISO 3...perhaps because there is too great a reliance on TPU foam vs more traditional foam to balance out the shoe. I do like the Triumph ISO 4, but it is not the ISO 3. I will be buying a couple more pairs of the ISO 3, just to have them. I greatly appreciate Saucony helping my feet, and offer this feedback not as criticism, but as critique. Thanks.

The 1st version of this shoe was fantastic and the versions since haven't been able to match this 1st shoe . The latest version is comfy , but lacks everywhere else . Narrow toe box , the cage around the foot doesn't fit right . The tongue it to big and over padded & white ! . Poor design in my opinion . Colour choices lately are poor as well , with the kinavra 8 , I prefer the green colours

I want to say that I love the Triumph ISO 3 and have purchased probably 4 or 5 pairs of them. I purchased a pair of Triumph ISO 4 in the exact same size and they were too long for me. I wore them for about 19 miles before I realized they just didn't fit right. Unfortunately by that time I had already run in them so I couldn't return them. I'm not sure if there was a bad batch or something since I purchased at launch but I am about to start on my last remaining pair of Triumph ISO 3 and I worry that I won't be able to find a comparable replacement since the ISO 4 is not a suitable replacement for me.
