Saucony Liberty ISO Running Shoes

Experience the ultimate in lively cushioning with the Liberty ISO. Featuring full-length EVERUN, your run starts amazing and stays amazing, while ISOFIT lacing offers a custom feel.

Stretch Mesh Upper

Engineered stretch mesh uppers will encase each foot in breathable comfort. Perforations in the fabric increase airflow to create a better, healthier environment for your feet to thrive in. ISOFIT technology creates a dynamic fit system by adapting to the shape and motion of the runner's foot, eliminating millimetres of movement with each stride. The woven heel plus external heel counter secure the rearfoot, uniting with ISOFIT technology to promote complete lockdown, anchoring you to the midsole and reducing in-shoe slippage so that you can enjoy smooth, distraction-free strides.

EVERUN Midsole

A full-length platform of EVERUN sits between your foot and the ground, for the ultimate in soft landings and springy takeoffs. EVERUN is created by stream-fusing thousands of bouncy TPU beads; it yields 83% energy-return with a construction that is three times more durable but three time less temperature-sensitive that standard EVA. Supplementing an already-lively midsole, a layer of TPU foam (named an EVERUN Topsole) lies below the sockliner to help maintain impact protection. This plush, propriety construction means that resilient cushioning is brought closer to the foot and because the force is distributed over a larger surface area, peak pressures are lowered on each stride. This winning combination means your use of superfluous muscle power is reduced, diminishing fatigue and enhancing performance, keeping you motivated for longer. Saucony contrast their cushioning with a medial TPU guidance frame; it curbs overpronation, improving stability while reducing risk of injury.

Crystal Rubber Outsole

A Tri-Flex outsole completes the Liberty ISO. It works with the EVERUN topsole for increased force dispersion over a greater surface area while also delivering optimal flexibility and traction. Made from Crystal Rubber, the outsole provides great traction and durability with increased pliability for a fluid feel. Saucony have built up the medial side of the outsole to further enhance stability and control of pronation.
