Even though the ISO is not THAT heavy, I would like to see it continue to slim down a bit more.
I can see the Peregrine ISO being a popular shoe for most trail runners. Experienced runners could take it Ultra length. Heavier runners could use it for faster and shorter runs. New trail runners would be able to have one shoe that checks every box.
Notable element of the Saucony Peregrine ISO
- The Saucony Peregrine model received an updated upper in the Peregrine ISO version. The shoe uses the same technologies found in the latest Peregrine 8 model but with an ISOFIT dynamic upper. It aims to give runners a soft, sock-like fit.
Saucony Peregrine ISO size and fit
In terms of sizing, the Peregrine ISO runs true to size and it has a medium measurement in the heel, midfoot and forefoot. The toe box is medium, allowing the toes to spread comfortably and the ISOFIT upper adapts to the natural shape of the foot, giving it a nice, comfortable wrap. The women’s and men’s version is available in standard B - Medium and D - Medium width options.
Designed for the trail, the Saucony Peregrine ISO uses the PWRTRAC outsole, which is also used in other Saucony running shoes. The main function of the PWRTRAC is to provide reliable traction and durability to the shoe. The PWRTRAC compound is more durable than other rubber materials and it is configured with hexagonal pattern and 6mm lugs for grip and stability on varied terrain.
Flex grooves are also added into the outsole to provide flexibility whenever necessary. The grooves adapt to the foot as it flexes while running.
In the midsole is the EVERUN Topsole that extends from the heel to the forefoot. This full-length midsole material offers a more responsive and springy ride
The EVERUN Topsole construction works well with the PWRFOAM, which is designed to reduce landing impact. These two midsole technologies aim to provide runners with high-energy and continuous underfoot cushioning throughout the run.
In the upper of the Saucony Peregrine ISO is the well-known ISOFIT technology. It is composed of a flexible mesh material that follows the natural shape of the foot. The mesh flexes as the foot moves to different directions while running. It also aims to give the foot a smooth, sock-like fit.
Also in the upper are the Flex Film overlays that are designed for a snug and secure fit. These overlays are made from thin film, so it does not add weight to the overall design of the shoe.
For added durability and foot protection, Saucony also adds a rubberized toe tip in the Peregrine ISO.
The shoe also features a gusseted tongue to prevent small stones and trail debris from entering the shoe. It also has a RUNDRY collar lining that has a moisture-wicking capacity.
The collar and supportive heel counter also enhance heel fit and secures the heel while running.
