Video reviews and unboxing

  • The Saucony Guide ISO 2 is a running shoe that’s meant for the roads. It is also designed for those who have overpronated foot motion. The underfoot platform is composed of two full-length foams that work together to provide a steady and comfortable base for the foot. A medial post supports the arch, saving it from rolling inwards too much.
  • The upper unit of this stability shoe is made of stretchy mesh that accommodates the natural shape and movement capacity of the foot. A moisture-managing internal lining prevents sweat from staying in the padded contours.

The Saucony Guide ISO 2 is true to size. Runners are encouraged to get the size that fits them the most, though trying out the shoe first before making a purchase helps in attaining a comfortable experience. Widthwise, the available options for men are D – Medium and 2E – Wide; the women’s version has the B – Medium and D – Wide variants.

The high-wear areas of the Saucony Guide ISO 2’s outsole unit are covered by a rubber compound called XT-900. This durable layer is meant to protect against wear-and-tear. It is also tasked with providing traction over the surfaces. The XT-900 rubber is also placed in the outsole of the Omni 16 and other durable shoes from Saucony.

IBR+ is a layer in the forefoot that’s made of blown rubber. It protects against abrasion, yet it also contributes to the overall cushioned feel through its spongy construction.

Tri-Flex is a design that focuses on the flexibility of the outsole. It involves a convex forefoot design and zigzagging grooves that facilitate a smooth transition to the toe-off phase of the gait cycle.

PWRFOAM serves as the base of the Saucony Guide ISO 2’s midsole. It is tasked with attenuating impact shock during the landing phase and converting it into kinetic energy that the foot can use to energize the liftoff.

EVERUN™ is used as a topsole, and it’s meant to put more liveliness into each step. It has a bouncy nature that encourages the foot to push off the ground with fervor.

A stability post is added to the medial side of the platform. This dense EVA (ethylene vinyl acetate) hunk is made to correct overpronation. It also prevents the tendons and muscles of the underfoot from being strained.

The FORMFIT is a sockliner that adds some more cushioning for the underfoot. It follows the contours of the foot-pad, thereby supporting the curves that aren’t usually given any attention.

The upper unit features the ISOFIT foot-hugging technology. This system of stretchy mesh and overlays adapts to the shape and motion of the foot, thereby giving a secure yet agreeable coverage.

The RUNDRY moisture-wicking fabric outlines the interior sleeve. It is meant to prevent sweat from seeping into the walls of the upper unit, staving off odor in the process.
