Updates to Saucony Guide 13 TR

  • The Saucony Guide 13 TR is an update to the recent trend of Guide models that used the ISO name. The removal of the ISO moniker means that the ISOFIT foot-hugging technology is taken out of the series, with printed overlays and engineered mesh serving as the cover system.
  • The midsole is also changed as it now features the PWRRUN topsole, a lighter and softer replacement of the revered yet obsolete EVERUN. Furthermore, this stability running shoe emphasizes pronation correction and in-shoe steadiness via a slightly raised lateral side and a dense medial post.

Size and fit

The Saucony Guide 13 TR is constructed to be true to size. Runners are permitted to get this product with their usual sizing expectations in mind. It is highly recommended, however, to get a feel of this product’s in-shoe experience and to study reviews that cover the size aspect to fully achieve a relaxed yet secure wrap.

This Saucony running shoe ditches the finger-like eyestays of the ISOFIT. However, it still offers quality sideways coverage with the stretchy engineered mesh upper and thin printed overlays. The foot-shaped platform is also an element that welcomes the natural shape of the human foot.


An extra-sticky rubber is used for the outsole unit of the Saucony Guide 13 TR. The job of this compound is to make this trail running shoe as grippy as possible. Its adhesive nature can boost confidence when traversing wet ground. Moreover, it is touted to be durable enough to withstand abrasion and general wear. Trail-optimized gripping lugs are patterned on the surface of the external pad.


The midsole unit of the Saucony Guide 13 TR uses the FORMFIT, a technology that involves three fundamental elements: a base, a topsole, and a removable footbed. The first element, the base, is a molded foam that handles the impact forces that are generated by the foot-strike. It also maintains the structural integrity of the topsole.

PWRRUN is the topsole unit of this product. This update to the EVERUN technology boasts an increase in softness and responsiveness. It is also meant to be lighter than its predecessor. Powerful toe-offs are the supposed end-result of the PWRUN.

A contoured footbed is the final element of the FORMFIT, and it is the surface on which the foot relaxes throughout the running session. The raised arch gives support to the midfoot, an area that is seldom given any attention. This feature can be removed or replaced with a new one if the runner wants to do so.

A dense TPU Guidance Frame is placed on the medial side of the platform. The goal of this add-on is to prevent overpronation and maintain an injury-free run. It works with raised lateral sidewalls to stabilize the foot and keep it centered while it’s in the interior compartment.


The upper unit of the Saucony Guide 13 TR is made of engineered mesh. This technology is a trusted part of many updates to modern running shoe series (like the popular Hoka One One Bondi line). The cloth-like nature of this element is its selling point. It has a seamless configuration, and it is lightweight and stretchy. It also has obvious breathing holes for ventilation. It is fundamentally an irritant-free sock that wraps around the foot.

Printed overlays provide a snug and secure hug. They don’t hog the upper unit’s real estate, though their presence affects the quality of the fit.
