Saucony Triumph ISO 4 First Run Impressions: Smooth All Over

Article by Sam Winebaum, Editor

Just got in my 1st run in the Saucony Triumph ISO 4, actually wearing the ISO 4 on one foot and the ISO 3 on the other to closely compare.
Triumph ISO 4
Now with a full Everun TPU midsole, it is nicely energetic but unlike full Boost TPU midsoles without EVA or plastic pieces to stabilize such as the Ultra Boost, here it is stable and tamed due to the burly outsole or maybe the different makeup of Everun which seems slightly firmer than Boost. 

The downside of the full Everun midsole in ...weight. My size 9 pre production sample weighs over 11 oz. Final production weight should come in at 10.6-10.8 oz so very close to the weight of the ISO 3 of 10.5 oz They do run way lighter than their weight due to their smooth transition and rebound and also for that matter lighter than the 10.7 oz Triumph ISO 3 on my other foot. We will be confirming final production weights as early samples can vary.

The redesigned decoupled (see longitudinal grooves up front) outsole makes them transition more smoothly than ISO 3 but overall with a touch less of a firmer pop off the heel despite the fuller rubber coverage there as the midsole is softer but also transmits far less shock.

The upper is very plush, decently supportive but light on the foot overall with less overlay material in the ISOFit bands than ISO 3. No pressure points anywhere. As a result, the half size up sample size 9 is a touch to big for me whereas at half up the ISO 3 is just right.  I would go true to size with a next pair.

More miles to run for sure but Triumph ISO 4, despite what appears despite a class leading weight, to likely to become a new favorite in the premium, plush daily trainer category for his just right cushioning softness, comfortable upper, and smooth transitions.  
When compared to the ISO 3, my early impressions is that overall it is a slightly softer shoe, one that transitions more smoothly, but while bouncier from the Everun with a touch slower response. The upper is clearly superior in comfort and hold and more accommodating  
It is smoother running at slower paces than the heel heavy TPU based Energy Boost 4 (RTR review), has a more refined less constrictive upper than the Gel-Nimbus 19 (RTR review) its closest comparison in terms of ride, a firmer more stable heel than the Brooks Glycerin 15 (RTR review), and a softer ride and easier toe off than the Nike Vomero 18 (RTR review).

Hi,
Is it softer in the heel and front (iso 4) than the saucony triumph iso 3? Is it as stable? Which is more responsive shoe? I wasn't sure by your comments - I think you said the iso 4 has faster transition but dosen't have the pop in the heel of the iso 3. Would you see the iso 4 as an upgrade overall or more a side grade. I have the iso 3 so it would be helpful whether to stay with it or not. Thanks.

Hi Anonymous,
It is early in my evaluation but yes it is a touch softer than ISO 3 overall. I would say the ISO 3 is a bit more responsive but also harsher in feel, more shock transmitted. Transitions in the ISO 4 are smoother. The full Everun midsole is the big change. There is no question it makes for a more comfortable somewhat bouncier ride but shoe gains about 0.7 oz in weight, not that noticeable. If the ISO 3 upper works for you the ISO 4's while more comfortable is not a huge change. Hope this helps

Thanks for your quick response. Would you say they as soft as the saucony freedoms? or slightly firmer. Also would you say they are more for slow and moderate pace like the triumphs 3s or can you do faster paces in them too. Sounds like they have quite a bit of bounce to them too. Thanks

Hi Anonymous,
Not as soft as Freedom whose softness I think comes mostly from the softer less substantial outsole, particularly at the heel, less drop and no heel counter on Freedom. Unlike Freedom also plenty of forefoot cushion. So ISO 4 is more stable. In terms of faster slower paces similar to ISO 3 but with more bounce but a touch less response as not as firm, a more comfortable upper, and a smoother transition.

Is the Triumph ISO 4 a softer or firmer ride than the Glycerin 15? Appreciate your reviews very much. Thanks!

Hi Anonymous,
A slightly firmer ride for Triumph ISO 4 from what I can tell so far but with more bounce. I find Glycerin a bit to soft for me.
Thanks for reading!

Thanks, is the saucony triumph iso 4 slightly softer in the heal than the saucony triumph iso 3. I found the saucony iso 3 a little too firm in the heel. Thanks and love your reviews.

ISO 4 is slightly softer in the heel than ISO3 due to the Everun
