Our wear testers loved fit, comfort and shock absorption of the Saucony Triumph ISO, however we felt the shoe was soft and slow. The Triumph’s cushioning felt similar in comparison to the Adidas Boost series however less responsive. The soft midsole was inferior to the Mizuno Wave Creation and other maximal trainers like Hoka One One or Altra lines. This shoe is best for the neutral runner looking for a comfortable shoe with plush cushioning who is not concerned with speed.
The Saucony Triumph ISO—the12th edition of the model—shaves a half an ounce off the previous version while increasing the stack height by 3mm. The Triumph ISO also debuts Saucony’s Isofit system (proprietary external caging system overlaying a flexible inner sleeve). This system allows for independent foot motion through four eyelets, which connect to the sole via thin plastic pieces. This caging along with a thick inner sock liner will easily accommodate feet of all shapes. An updated platform removed the midsole plastic shank, allowed for 20 percent increased cushion and all this without added weight. This shoe was comfortable but most effective on runs 10k and over.
Comfort The sock liner with external caging is the Saucony Triumph ISO’s hallmark feature and Saucony’s most innovation feature in recent years. The soft sock liner had only a few seams and fit snug without developing any hot spots on long runs. The tongue and heel collar had ample soft foam padding and protected the foot from lace tension. Forefoot mesh was airy and without excess material or bunching when really tightening down the laces.
Speed Weighing in at 10.4oz this shoe felt every ounce as heavy. Regardless of the 8mm drop, I felt most comfortable when heel striking. The plush midsole created superb comfort however at the price of slow speed. This shoe is not for speed work or tempo sessions but rather everyday running. Responsiveness The midfoot felt only moderately responsive. Shock was comfortably absorbed at ground contact however there was a lack of return. For a traditional shoe I felt rather average transitioning into flight phase.
Value Compared to other like priced high-end comfort trainers the Triumph excels in comfort and fit. For $150 the Hoka One One Boni 4 or Mizuno Wave Creation 16 are better options when taking into account both performance and comfort.
Heeluxe, our shoe testing laboratory partner, tests the responsiveness of a shoe by measuring how thick a running shoe is and multiplying it by how much pressure the forefoot foot feels while running. The softer or thicker the midsole, the less responsive a shoe will feel, but the more comfortable the shoe will generally feel. The thinner or firmer a midsole is, the more power you’ll feel at toe-off.
