The Saucony Peregrine 10 ST is a product that has been constructed to handle soft terrain, hence the ST part of its moniker. The design of the whole silhouette is similar to its all-terrain counterpart, the original Peregrine 10 model, save for an extra aggressive outsole design that can hold its own on muddy or slippery ground and a water-resistant upper that can handle wet environments.

Size and fit

The Saucony Peregrine 10 ST is made to be true to size. Runners can use the sizes with which they are most comfortable to fully enjoy an in-shoe feel that is accommodating. Still, it would be helpful to test the shoe first or study user reviews that cover the aspect of size to be sure about the quality of the wrap.

When it comes to the sideways fit, the elements that assist with the perception of balance and security include the foot-shaped platform and the generous, curved outline of the upper unit. This running shoe aims to welcome the natural shape of the human foot.


PWRTRAC is the technology that is used for the outsole unit of the Saucony Peregrine 10 ST. The job of this element is to protect the bottom part of the cushioned platform from the abrasive nature of the trails. It has a durable nature to maintain its form and structure at all times. It also doles out traction, a trait that is highly important when traversing soft ground.

Unlike the consistency of the Peregrine 10’s arrow-shaped gripping lugs, the lug pattern of the Peregrine 10 ST is deliberately aggressive, with zigzag shapes governing the traction-heavy design. The multiple points and ends of each gripping node heighten surface adhesion, particularly on mushy ground.


PWRRUN is the material that is used for the midsole unit of the Saucony Peregrine 10 ST. The job of this layer is to shield the foot from the irregular nature of the trails. It is also responsible for mitigating the impact shock during the foot-strike and motivating the foot to perform an energized toe-off.

FORMFIT is a contoured midsole design that welcomes the wavy outline of the underfoot. Balance and comfort are traits that are encouraged by this design aspect. Many Saucony series feature FORMFIT, including the ever-popular Saucony Triumph line.


The upper unit uses a reinforced textile that is meant to resist wear-and-tear. Runners can enjoy a confident run through the outdoor terrains because this accoutrement doesn’t succumb to abrasion.

A water-resistant layer is added to the facade. The purpose of this feature is to permit the shoe to remain dry when subjected to environments that are damp or muddy.
