The Saucony Triumph ISO 3 was recently released and I got a chance to demo them during for 5k run during a Saucony demo event at my local Running Room. The Triumph is Saucony’s premium neutral everyday trainer and I will highlight some of the construction differences, along with my fit and running impressions.
The third version of the Triumph ISO received a minor update to the tooling (midsole and outsole) and a major upper change. The most significant change in the midsole is the expanded volume of the Everun TPU foam heel insert. Previously, the Everun was a lateral side heel insert. Now, it wraps completely around the heel to the medial side as well. There is a cut-out in the outsole under the heel which makes the Everun visible. The full-length Everun topsole is retained from v2. The outsole design is mostly unchanged, keeping the same chevron pattern as v2.
The upper has received a significant update, I think partly to address some of the durability issues found in v2. The ISO frame is now fabric instead of plastic and only covers the top two eyelets, rather than three eyelets in the previous version. The lower eyelets are attached to the overlays on new engineered mesh in the toebox area. The overlays wrap mostly around the base of the toe, with the exception of a large overlay over the lateral metatarsal area, where the Saucony logo sits.
Notably, the eyelets are now ghillie-style (fabric loops), rather than traditional holes. This should help the fit by allowing the lacing to slide back and forth through the eyelets more easily.
The tongue and heel collar are very plush, with substantial foam stuffing. This is unchanged from the prior version. The heel counter appears to be reduced down to a single plastic loop around the back. The prior versions had either a plastic frame (v2) or a solid counter (v1).
The Triumph ISO 2 is fairly roomy in the toebox and slightly short for size. The lateral edge pushed slightly against my outside toes. Part of the issue may have been the thick foam in the heel collar pushing my foot forward into the shoe a bit. I didn’t have any issues with heel slippage or another fit concerns. Fit is very individual and these are my impressions on how it works with my medium to wide feet. I tested the ISO 2 a few months ago and found the fit to be extremely similar.
I ran mostly moderate speeds with a few quick intervals thrown in. This is a substantially cushioned shoe. There is decent forefoot cushion and a massive amount of heel cushion. I am normally a forefoot striker, but I switched to a heelstrike gait pattern for some of the test to see how it would work for the majority of this shoe’s audience. It is super plush on heel set down with a very smooth transition to toe-off. I felt there was good energy return and rebound – better than v2.
The Triumph felt ok during the faster running, although I definitely felt the mass and volume of foam being carried around. This shoe’s forté is high-mileage, medium paced runs.
Overall, the cushioning is similar to v2 and the increased responsiveness makes it an overall improvement, in my opinion.
The Triumph ISO 3 is a solid shoe that delivers superior cushioning and the fit should work for most. If you liked the Triumph ISO 2, the ISO 3 should be a natural transition.
