Saucony Liberty ISO 2 Women's Running Shoes

A jolt of energy with a supportive edge. For those looking to achieve their personal goals, Liberty ISO 2 lets one boldly chase after them with a light and springy feel that has a touch of stealth stability to keep you comfortable as the miles rack up.

Isoknit Upper

Constructed with an ISOKNIT dynamic upper, the Liberty ISO 2 will encase each foot in breathable comfort. The ISOKNIT upper adapts to the shape and motion of the runner's foot providing freedom of movement for a natural running motion. The engineered knit provides comfortable support and increases airflow to create a better, healthier environment for your feet to thrive in. ISOFIT technology provides a secure fit with a stretchy internal saddle and external segmented tabs working together to provide a locked-in, close-to-foot fit, with new ISOWIRE reinforcements minimising heavy bulk and excess material. A woven heel increases the structure of the shoe without adding bulk keeping you fast on your feet whilst securing the rearfoot in place so you can enjoy smooth, distraction-free strides. An engineered mesh toebox offers both structure and stretch where it's needed for powerful and comfortable toe offs, whilst enhancing breathability for cool comfort. New higher midsole sidewalls increase guidance and help to reduce overpronation keep you stealthy and stable.

EVERRUN 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 times less temperature-sensitive than 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. Combined with Saucony's FORMFIT 3D contoured footbed, the three-layer foam footbed cradles the foot for increased support and better adaptability. Completing the midsole is a medial TPU guidance frame, helping to curb overpronation and improve stability keeping each step quick and comfortable whilst reducing the risk of injury.

TRI-FLEX Crystal Rubber Outsole

A Tri-Flex outsole completes the Liberty ISO 2. 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. The tuning fork design of the outsole offers more guidance encouraging the foot to follow grooves in the outsole to make each step quick and comfortable whilst subtly counter excess motion.
