Liberty ISO provides cushioning and improves energy return

The creators of the Saucony Liberty ISO made the EVERUN Topsole construction, which is meant to deliver an additional layer of cushioning. This material's primary purpose is to improve energy return.

In correcting overpronation, a Medial TPU Guidance Frame is utilized on the inside part of the shoe. This rigid plastic piece helps in preventing and controlling overpronation.

Saucony Liberty ISO midsole

Increased energy return and shock absorption are offered by the full-length EVERUN midsole. This material is essential in achieving a more consistent ride and smoother landings.

Saucony Liberty ISO provides sock-like fit

A stretchable mesh called the ISOFIT creates a sock-like and soft feel. The technology is strategically placed to primarily adapt to the runner's foot movements, shape, and size. It allows the foot not to feel restricted.

Lightweight breathability is offered by the Engineered Mesh, which has also been reconstructed to be denser and more supportive. The manufacturers made this component of the shoe to keep the runner's foot cool and dry, especially on summer runs.

The shoe has a Heel Support Frame which is essential in supporting the heel throughout the gait cycle. It helps the runner to move more confidently and securely with every stride.
