Free to Go Farther: Introducing the Liberty ISO

Maintaining our relentless commitment to both the runner and performance innovation with the launch of the all-new Liberty ISO, a high-performance, lightweight trainer that builds on the DNA of the brand’s highly-successful Freedom ISO.

A slightly more supportive alternative to the neutral-category Freedom, the Liberty ISO extends the fast and responsive ride of its first cousin with added features, including a refined ISOFIT™ system and a re-engineered mesh upper, resulting in a unique and dynamic running experience for all.




“The design of the Liberty ISO and the Freedom ISO run parallel,” said Pat O’Malley, senior vice president of global product for Saucony. “The Freedom ISO has been the most successful product launch we’ve experienced over the past few years. The Liberty ISO builds on the genes of the Freedom, Saucony’s first-ever performance running shoe with a full-length EVERUN midsole. The Liberty augments the Freedom’s DNA with added guidance in the form of a lightweight medial TPU bridge for runners wanting just a little extra stability. With the Liberty ISO, now even more runners can be free to go farther.”

The Liberty ISO’s full-length EVERUN midsole maintains cushioning properties three times longer than standard EVAs while returning 83% of the energy absorbed. In addition to the full-length EVERUN midsole, the Liberty ISO also incorporates EVERUN Topsole construction for even greater energy return and continuous, fluid cushioning with every stride-no matter how long the run.


The Liberty ISO features a medial TPU guidance frame that cups the inside of the midsole to provide a dash of medial support. This, combined with a built-up TRI-FLEX™ crystal rubber outsole along the medial side of the shoe, offers a touch of guidance while still delivering EVERUN’s energetic and responsive ride.




The Liberty ISO features the brand’s racing-inspired ISOFIT dynamic upper, an ultra-soft, inner fit-sleeve crafted out of stretchable air mesh that morphs to the foot for a sock-like feel. As the ISOFIT sleeve creates a dynamic fit system, the breathable engineered stretch mesh upper and streamlined heel support frame add to the shoe’s impressive fit and lightweight performance.





The Liberty ISO is available from good running stores, The Athlete’s Foot and from December 2017.
