The Altra Lone Peak 4.0 is a popular alternative to the Saucony Peregrine ISO, known for its zero-drop platform and foot-shaped toe box. While both shoes offer excellent traction, the Lone Peak 4 may be preferred by runners who seek a more natural foot position and a wider toe box. However, the Peregrine ISO's ISOFIT upper and responsive cushioning might be more appealing to those who prioritize a secure fit and a balance of protection and ground feel.

The Nike Wildhorse 5 is another trail shoe that runners might compare with the Saucony Peregrine ISO. The Wildhorse 5 features a waffle-patterned outsole for traction and a rock plate for protection. It's a solid option for runners who need extra underfoot protection and a durable build. However, the Peregrine ISO's ISOFIT upper and PWRFOAM midsole may offer a more comfortable and adaptive fit for those who value comfort and a personalized feel.

In Depth


Upper

The ISOFIT dynamic upper of the Saucony Peregrine ISO is a standout feature, providing a secure and adaptive fit that accommodates various foot shapes. This engineered mesh upper ensures breathability while keeping out debris, and the integrated TPU (thermoplastic polyurethane) cage locks the foot in place, reducing internal movement during runs. The result is a trail shoe that offers both protection and a custom-like fit, allowing runners to tackle technical trails with confidence.

Midsole

The midsole of the Saucony Peregrine ISO is composed of PWRFOAM, offering a cushioned yet responsive ride. This material, coupled with the EVERUN topsole, delivers long-lasting comfort and energy return, which is particularly beneficial during extended runs on rugged terrain. The midsole's design supports a smooth transition from heel to toe, contributing to the shoe's overall stability and performance.

Outsole

Equipped with a PWRTRAC outsole, the Saucony Peregrine ISO boasts aggressive lugs that provide exceptional grip on a variety of surfaces, from muddy trails to rocky inclines. The outsole's design ensures that runners maintain traction in slippery conditions, although it may retain mud in certain scenarios. Despite this, the outsole's durability and ability to handle diverse terrains make it a reliable component of the shoe.

Size/fit

The Saucony Peregrine ISO offers a versatile fit that caters to a wide range of foot sizes. The ISOFIT system allows for a snug fit without being overly tight, and the shoe is available in different widths to accommodate runners with wider feet. The consensus among users is that the shoe fits true to size, providing a comfortable and secure running experience.

Comfort

Comfort is a hallmark of the Saucony Peregrine ISO, with a plush collar and cushioned tongue that enhance the overall feel of the shoe. The EVERUN topsole contributes to the underfoot comfort, ensuring that each step is well-cushioned, even on hard surfaces. The shoe's comfort features make it suitable for long-distance runs and extended periods of wear.

Cushioning

The Saucony Peregrine ISO's cushioning is achieved through a combination of the PWRFOAM midsole and the EVERUN topsole. This setup provides a balance of softness and responsiveness, absorbing impact while allowing for an energetic push-off. The cushioning is sufficient for trail running, offering protection without compromising ground feel.

Breathability

The engineered mesh upper of the Saucony Peregrine ISO ensures breathability, keeping feet cool and dry during runs. The material allows for air circulation while preventing debris from entering the shoe. This breathability is particularly beneficial in warmer conditions or during intense trail runs where ventilation is crucial.

Stability

The Saucony Peregrine ISO's low-profile design and 4mm heel-to-toe drop contribute to its stability on uneven terrain. The shoe's outsole provides a solid foundation, and the flexible midsole allows for natural foot movement. These features, combined with the secure upper, result in a stable trail running shoe that minimizes the risk of ankle rolling.

Durability

Durability is a strong suit of the Saucony Peregrine ISO, with reinforced areas in the heel and forefoot to withstand trail hazards. The robust mesh upper and resilient outsole materials ensure that the shoe holds up well over time, even with regular use on challenging trails. The shoe's construction is designed to endure the rigors of trail running without premature wear.

Grip

The grip of the Saucony Peregrine ISO is one of its most praised attributes. The PWRTRAC outsole, with its deep and aggressive lugs, provides excellent traction on a variety of terrains, from soft ground to technical rock. The shoe's ability to maintain grip in different conditions makes it a reliable choice for trail runners seeking a versatile performer.

Who should buy the Saucony Peregrine ISO?


The Saucony Peregrine ISO is well-suited for trail runners who seek a shoe that offers a blend of comfort, protection, and traction. It's ideal for those who run on mixed terrain and need a shoe that can handle everything from soft ground to rocky paths. Runners who appreciate a low drop design for a more natural running experience will find this shoe to be a good match. Additionally, those who prioritize a secure and adaptive fit will benefit from the ISOFIT dynamic upper.

Who should not buy the Saucony Peregrine ISO?


Runners who primarily stick to road surfaces or prefer a minimalist design may not find the Saucony Peregrine ISO to be the best fit. Its aggressive outsole and cushioning are specifically tailored for trail running, making it less suitable for urban environments. Those who require a shoe with a wide toe box or prefer a high level of cushioning for ultra-distances might want to consider other options.

Saucony Peregrine ISO: What's it good for?


The Saucony Peregrine ISO is excellent for trail running across various terrains, including dirt paths, rocky inclines, and grassy fields. Its robust grip makes it suitable for wet and slippery conditions, while the responsive cushioning is ideal for long-distance runs.
