Saucony Peregrine ISO


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.

Women’s Saucony peregrine ISO

LOVE these shoes. Never have I purchased shoes online, but I did my research, read reviews, thanks to all who took the time, and these are truly terrific shoes. Like a glove from the minute I put them on. I wanted wide in the toe box, narrow in the body, and easy to snug in the heel without cutting off circulation! They mold to my foot each time I lace them up. Great laces, great support, no binding, no stiffness, no discomfort. We were one on the trail first time out. Cannot say enough. But read the reviews, people are good at saying what they do and do not like and it’s a huge help. Love the fabric, love the big lugs, even though I hate leaving them outside, love the color! And to think I almost ordered gray. It’s okay but not when there’s purple! With peach lugs. And striped laces. Woot! Got a good deal too, thanks FF. Did not want to pay a boatload even though I know you get what you pay for sometimes. Very happy with my purchase. I will buy these again. Only my second Saucony. Didn’t love the first pair. I love Brooks Cascadia, but wanted a change. Love Mizuno, Montrail, ASICS. But I’m a peregrine ISO fan now! Got half size larger than regular shoes, like I always do, perfect fit. Harold would have given up his purple crayon for these. : )

Amazing. Comfortable from the word GO! I wish they had a slightly higher arch; but overall- AMAZING.

I love the Saucony Peregrine!

These are the most comfortable trail shoes I have ever worn! I am on my fourth pair for good reason. The traction is insane and they are lightweight and soft underfoot. I highly recommend this shoe.

I run the hilly back roads of the Ozarks and need a shoe that can handle gravel, rocks, water, mud, sand and occasional cow patty. I’m extremely happy with the way they grab onto Mother Earth and don’t let go. They are solid on my feet when handling the rough stuff and smooth enough to enjoy the normal dirt road. Minimal slip sliding on gravel beds and they really grab when going uphill. I’m a 65 yo female running at 11 min pace and loving my back road runs.
