Saucony Triumph Iso 3 Women’s Review

WR takes a look at the latest version of the Triumph Iso


Since Saucony rebranded its premium neutral cushioned shoe, the Triumph, in December 2014, the shoe has undergone some serious modifications. The new Triumph Iso was rebranded to reflect the shoe’s revamped upper system, named ‘ISOFIT’, designed to adapt to the shape and motion of the foot. A year later came the Triumph Iso 2, featuring a brand new EVERUN foam in the topsole, offering close-to-the-foot cushioning and enhanced energy return. Both components we liked and we were very much satisfied with when we tried the shoe out last year. Needless to say, when we received the latest iteration of the shoe, the Saucony Triumph Iso 3, into the office last month, we were very intrigued to find out what Saucony had decided to do next…

The immediate difference we noticed was the shoe’s new upper – now constructed from an engineered mesh fabric with fewer overlays, offering a much closer-to-foot fit. We liked this a lot when we tried them out. While these shoes are never going to have the same luxurious ‘sock-like’ feel as Nike’s Flyknit numbers, the upper on the Iso 3’s is much snugger than on the previous version, and also feels less rigid. This is probably due to the adaption of the ISOFIT cage through the midfoot, which has been reduced by a third. This gives better elasticity through the lacing and creates an all-round more flexible and comfortable upper.

Beneath the foot, things appear to have remained largely same – which were pleased about. You still get a 3mm layer of EVERUN foam above the heel pad, offering the same bouncy and cushioned ride and excellent resiliency. The EVERUN heel landing zone has increased, though, to add maximum energy return at heel strike – something that was immediately noticeable to us and our tester was a huge fan of as a heel striker.

Less obvious to our tester, though, was the effect of the deepened forefoot groves and wider landing strips on the shoe’s signature TRI-FLEX outsole – she didn’t find the ride any smoother than that offered by the Iso 2 but that’s not to say the more the rigorous critic wouldn’t. And while Saucony’s signature TRI-FLEX outsole is designed to offer flexibility and greater ground contact, our tester found the outsole a little firm and also a little distancing, so perhaps not the ideal choice for those looking for a responsive shoe.

At 26g, the Saucony Triumph Iso 3 is not a particularly light shoe but its durability makes them an excellent choice for long-distance training. With a 8mm drop, the heel-to-toe differential is pretty average for a neutral running shoe, and is suitable for both forefoot and heel strikes with a neutral gait. That said, heel strikers may benefit more from the added bounciness that comes with the updated EVERUN heel landing zone.

So what do you get with these shoes that you didn’t with the Iso 2’s? A much more comfortable, flexible and form-fitting upper and an even plusher, more resilient ride. For neutral runners looking for a comfortable and well-cushioned shoe for long-distance training, these are a solid choice. They’re durable, and you can rely on them for comfort as you rack up the miles.
