Updates to Saucony Guide ISO 2 TR

  • The Saucony Guide ISO 2 TR received a trail-specific update in the outsole. It follows the design of the road version of the Guide ISO but it is made more protective and durable. The shoe features the PWRTRAC compound in the forefoot that delivers maximum grip and durability.

Size and fit

The Guide ISO 2 TR runs true to size in terms of sizing. It comfortably accommodates foot with medium measurements as the heel, forefoot, and midfoot are in a medium fit. Standard medium widths for both men’s and women’s versions are available.


In the outsole of this trail shoe is a combination of PWRTRAC and X-900 compounds. Both materials are designed to deliver durability and traction for varied trail surfaces.

The PWRTRAC compound delivers more durability and traction as compared to other traditional rubber materials. It is also designed to be equipped with the 6mm lugs that provide grip on soft and hard surfaces.

The presence of the flex grooves also delivers flexibility without compromising underfoot cushioning.


Just like its road version, the Guide ISO 2, the shoe features the notable EVERUN and PWRFOAM midsole cushioning.

The EVERUN Topsole, which is also used in other popular Saucony running shoes, is formulated for responsiveness. It also offers long-lasting cushioning that has a high-energy return for a bouncier ride.

The PWRFOAM is a reliable midsole cushioning that protects the foot during impact. It offers responsive cushioning that is consistent throughout the run. The foam is also more durable compared to traditional midsole cushioning.

The shoe also makes use of the FORMFIT contoured footbed. It gives added cushioning while enhancing fit.


An engineered mesh covers the upper of the Saucony Guide ISO 2. It offers breathability and comfort to the foot, especially on warm running condition.  

This mesh material works well with the ISOFIT design that delivers a dynamic fit. It adapts to the natural shape of the foot and it flexes as the foot moves to different directions.

The shoe has a padded tongue and collar for added comfort and enhanced fit. The RUNDRY collar lining has a moisture-wicking capacity to keep the foot dry and sweat-free.
