Updates to Saucony Guide ISO

  • The Saucony Guide ISO is a road running shoe that is intended for those who are moderate overpronators. It uses the ISOFIT system which aims to provide a more refined fit.
  • Featured on the outsole is the XT-900, the goal of which is to bring durable traction and long-lasting protection against wear and tear.
  • The midsole adds the EVERUN Topsole which is essential in providing extra cushioning to the foot.

Saucony Guide ISO size and fit

The Saucony Guide ISO follows the standard shoe measurements when it comes to sizing. The shoe is best for runners who want to take any road running activities. The available widths are B - Medium for the women's version and D - Medium for the men's version.

Outsole

In the forefoot area lies the IBR+. This flexible and lightweight material's purpose is to provide a more responsive ride and to enhance cushioning. It also includes traction, which is essential when it comes to holding onto the ground.

Covering the majority of the outsole surface is the XT-900. This carbon rubber material aims to deliver improved durability and increased grip on the surfaces. This reliable material is also used in the Guide ISO 2, Omni 16 and other shoes from Saucony for running.

By utilizing the Tri-Flex design, adaptability and flexibility in the forefoot are increased.

Midsole

Distribution of pressure is offered by the PWRFOAM technology. This cushioning compound is responsible for a more responsive and smoother ride.

The creators of the Saucony Guide ISO made the EVERUN Topsole construction as a means of delivering an additional layer of cushioning. This technology's primary purpose is to enhance energy return.

To correct overpronation, a Medial Post is utilized in the midfoot area. The inward rolling of the runner's foot after initial contact with the ground is controlled.

Wicking moisture and heel security are offered by the ComfortLite Sockliner. This molded material contours to the heel and arch to reduce pressure in the forefoot area.

Upper

The ISOFIT technology is integrated into this product. The stretchable mesh's goal is to adapt to the runner's foot movements, size, and shape. It creates a sock-like and soft feel.

A Strobel Last is utilized in this shoe. It is stitched to the HRC Strobel Board for enhanced cushioning. The manufacturers made this component to deliver a softer and underfoot feel.
