Saucony’s trail running legend takes flight again with the Peregrine ISO.

The Peregrine has long been one of Saucony’s toughest trail shoes, but the shoe got an upgrade this year from the Saucony Peregrine 8 with the addition of ISOFIT—Saucony’s breakthrough fit system that morphs to your foot for a custom-like feel. The enhanced upper adapts to the ebbs and flows of your foot as you navigate the trail.

Saucony softened the landings with a PWRFOAM midsole and increased energy return by inserting an EVERUN topsole. And to keep you on your feet, designers used a PWRTRAC outsole with deep rubber lugs to dig into the dirt.

So no matter where you want to go, the Saucony Peregrine ISO will get you there.
