Updates to Saucony Omni ISO 2

  • The Saucony Omni ISO 2 is a stability running shoe that is specifically designed to perform well on different paved surfaces. The shoe utilizes Increased toe-spring and heel bevel.  This is essential in supporting the runner with ease and comfort, especially when tackling long miles. It also features a more improved heel grab and lockdown. This is focused on providing a secured fit during the running session.
  • Featured in the Saucony ISO 2 is the updated TRI-FLEX outsole design. This is strategically built for more guidance and ground contact. Guidance is provided without compromising the flexibility of the shoe’s wide platform.

Saucony Omni ISO 2 size and fit

Based on their website, the Saucony Omni ISO 2 is true to size, but according to some users, the shoe runs big. Because of this, it's recommended to try the shoe on before purchasing. 

With its wide toe box, it ensures a comfortable fit with plenty of room for the toes to wiggle. When it comes to width, the available width options are D - Medium and 2E - Wide for the men's versions and B - Medium, D - Wide for the women's. 


The outsole of the Saucony Omni ISO 2 features a new Tri-Flex design. It offers flexibility without affecting grip and durability. 

Integrated into the shoe is the XT-900. This rubber material lies in the heel area that aims to provide durable traction.

Along with the XT-900 is the IBR+. This feature of the shoe is located in the forefoot section. This material is described to be flexible and lightweight that delivers improved cushioning. This component of the shoe is also focused on providing a more responsive ride. 


Like the Saucony Ride 10, the Omni ISO 2 also features the EVERUN midsole technology.  EVERUN makes up the midsole area of the Saucony Omni ISO 2. This material is described as a responsive foam unit that is running through the entire length of the footwear. Shock is attenuated during the landing phase and a powerful toe-off is encouraged. 

A high-quality EVA foam called PWRFoam is also utilized in crafting the shoe. This foam aims to provide additional comfort throughout the run. With the utilization of this material, the life span of the shoe is also extended.

A firm Medial Post is also placed in the midsole. Saucony adds this feature to limit pronation. This is significant in preventing excessive inward rolling of the foot that results in painful running experience.


The ISOFIT design is integrated into the Saucony Omni ISO 2. This dynamic fit system is the combination of the soft inner sleeve and the floating support cage. This technology is created to adapt to the movement and shape of the foot for a more customized fit.

A double jacquard mesh covers the forefoot area. It offers lightweight and breathable coverage. The perforations are huge enough for the air to pass through, keeping the foot dry and cool, especially in warm running conditions.
