After the huge success with Triumph ISO, Saucony has finally updated the model with a new, improved one, in the form of Triumph ISO 2. Both Triumph ISO and Triumph ISO 2 are running shoes geared towards people who need a lot of cushioning. People with ankle or knee pain may need extra cushioning on their shoes in order to attenuate road impacts. So, what are the differences between Saucony Triumph ISO and Saucony Triumph ISO 2? Is the new model really better than the old one? Below, you can read more about these two running shoes.
Saucony Triumph ISO 2 is generally more comfortable than Saucony Triumph ISO. This is because of the redesigned upper. While Saucony Triumph ISO 2 still uses the ISOFIT overlays, these overlays have been softened up a little bit. The overlays are now also shorter towards the front of the shoe, hence opening the toe box a bit more. Previously, the old Saucony Triumph ISO has four parts that can be pulled together via the saddle. Now, Saucony Triumph ISO 2 has only three parts. The more open design makes it more comfortable and is beneficial to prevent irritation.
Both models come with the Support Frame, which cups the heel for fit and support. But the Support Frame of Saucony Triumph ISO 2 has been changed a little to give slightly more flexibility and comfort.
Saucony Triumph ISO 2 has undergone a significant change in the midsole. Of course, both models have full heel-to-toe cushioning, but now Saucony Triumph ISO 2 comes with the EVERUN midsole and topsole construction. The EVERUN layer essentially adds a layer of softer foam directly under the foot. With this new feature, we certainly expect Saucony Triumph ISO 2 to be even softer and cushier than Saucony Triumph ISO. But tests show that the difference is pretty marginal. The heel of Saucony Triumph ISO 2 is just slightly cushier, improving the heel-strike performance and transition to toe-off.
Both models have full ground contact, and this contributes to their excellent stability. However, the jagged side-to-side tread pattern on Saucony Triumph ISO has been replaced with a fan-shaped one on Saucony Triumph ISO 2. The new design has wider flex grooves, which are great for more flexibility.
Overall, Saucony Triumph ISO 2 is an excellent improvement from Saucony Triumph ISO. It is more comfortable, and a tad more stable and flexible than the original Saucony Triumph ISO.
