Its predecessor, the Freedom ISO, broke new ground as the brand’s first-ever performance running shoe with a full-length EVERUN™ midsole. Now, the second-generation Freedom makes its debut featuring ISOKNIT, an engineered performance knit that works with Saucony’s racing-inspired ISOFIT system to deliver the brand’s most dynamic and unbounded running experience to date.


ISOKNIT is a performance engineered textile that delivers support, breathability, and freedom of movement. Combined with Saucony’s ISOFIT system, a soft inner sleeve and floating support cage, the Freedom ISO2 creates a dynamic fit system that adapts to the shape and motion of the runner’s foot.


The Freedom ISO2 features a full-length EVERUN midsole that 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 Freedom ISO2 also incorporates an EVERUN Topsole for even greater energy return and continuous, fluid cushioning with every stride.


Adding to the extraordinary durability and flexibility of the Freedom ISO2’s EVERUN midsole material, a TRI-FLEX™ crystal rubber outsole also displays exceptional resistance to wear. In addition to its resilience, the crystal rubber outsole allows for greater adaptation to different foot proportions and freedom of motion underfoot.


Weighing in at 258 grams for men and 232 grams for women, the 4mm-offset Freedom ISO2’s streamlined heel support frame adds to the shoe’s impressive fit and lightweight performance.


The Freedom ISO2 will be available at select speciality running retailers, The Athlete’s Foot and from July 2, in men’s in Black and ViziRed and women’s in Black, Aqua and White Noise.
