incrediRUN Explained
In brief: incrediRUN is Saucony's newest superfoam, introduced in 2025. It uses a proprietary TPEE (thermoplastic polyester elastomer) compound with a custom foaming process, and Saucony describes it as their most resilient foam ever used in a running shoe. Positioned above PWRRUN HG, it delivers exceptional energy return while staying soft, light and responsive, debuting in the Endorphin Elite 2 and Endorphin Trainer.
What is incrediRUN?
incrediRUN is Saucony's newest superfoam, introduced in 2025 and sitting at the very top of the brand's cushioning hierarchy. It is built around a proprietary TPEE compound, short for thermoplastic polyester elastomer, processed through a custom foaming method that Saucony developed in house. The brand describes it as their most resilient foam ever used in a running shoe, a bold claim that places it above even the high-performance PWRRUN HG. Designed for runners chasing the lightest, liveliest possible ride, incrediRUN represents Saucony's current state of the art and the foam they reach for in their fastest, most premium models.
How incrediRUN works
incrediRUN's TPEE base is a thermoplastic elastomer chosen for its blend of softness and rebound. Through Saucony's custom foaming process, the material is expanded into a structure that compresses readily underfoot yet snaps back quickly, returning energy to the runner with each stride. That combination of plush feel and high rebound is the holy grail of modern foam design, since softness usually comes at the cost of responsiveness. By engineering the foam carefully, Saucony aims to deliver both at once: a cushioned landing that does not feel mushy and a propulsive push-off that helps maintain pace. The result is a foam that feels fast as well as comfortable.
Where the foam sits in the range
Within Saucony's foam family, incrediRUN occupies the premium tier above PWRRUN HG. The brand's hierarchy runs from the versatile everyday PWRRUN, up through the softer PWRRUN+, the PEBA-based PWRRUN PB and the high-performance PWRRUN HG, with incrediRUN crowning the line as the most advanced compound. This positioning tells you a lot about its intended use: it is reserved for top-end, performance-focused shoes rather than entry-level trainers. If you want the most resilient, responsive foam Saucony currently makes, incrediRUN is it, and you will find it in the models built specifically to showcase that performance.
Which shoes use incrediRUN
incrediRUN made its debut in the Endorphin Elite 2, first seen in limited form around the Paris 2024 Olympics before a wider release in 2025, and it also appears in the Endorphin Trainer. The Endorphin family is Saucony's performance race-and-train line, so it is a fitting home for the brand's flagship foam. The Elite is the sharp, race-day end of the spectrum, while the Trainer offers the same foam technology in a more durable everyday package, letting runners train in the same responsive cushioning they would race in. Both put the foam front and centre as the headline feature.
Who incrediRUN is for
incrediRUN is aimed at runners who want the best performance Saucony can offer, whether for racing, key sessions or simply enjoying a premium, responsive ride. As a top-tier superfoam it commands a premium, so it makes most sense for those who will appreciate the energy return and lightness on faster runs. If your training is mostly easy mileage, a more durable everyday foam may serve you better day to day, with incrediRUN saved for the moments that matter. As ever, the right foam depends on how and how often you run, and our team are happy to help you weigh it up.
