86 / 100 based on 8 expert reviews

  • 90 / 100 | Harold's Desk

    The sole includes extra rubber along the interior side of the foot and while very visible the shoes supportive post under the arch provides stability without actually being noticeable underfoot on the run or impeding the flexibility.

  • 89 / 100 | Running Warehouse

    I'm on the trails a lot, but when I hit the roads I do like a shoe with a little bit more support. I find that the Liberty ISO provides that with the full-length EVERUN midsole, and at the same time it still has a little bit of flexibility that I like.

  • 90 / 100 | Solereview

    It's a cushioned and form-fitting trainer with mild support features. Expensive, though.

  • 90 / 100 | The Active Guy

    Saucony delivers with the first full EVERUN stability running shoe. The stability support and ISOFit upper matched with the EVERUN sole make this a solid stability shoe.

Updates to Saucony Liberty ISO

  • The Saucony Liberty ISO is a road running shoe that is intended for runners who are moderate overpronators. It utilizes the ISOFIT system. The technology's purpose is to provide a sock-like feel.
  • Featured on the outsole is the Tri-Flex Crystal Rubber, the goal of which is for increased durability and adaptability.
  • The midsole utilizes the full-length EVERUN Topsole which aims to provide additional cushioning.

Saucony Liberty ISO size and fit

The Saucony Liberty ISO follows the standard shoe measurements when it comes to sizing. The shoe is best for those who want to take any short and long-distance road running activities. The available widths are B - Medium for the women's version and D - Medium for the men's version.


The Tri-Flex Crystal Rubber is integrated into this product. This material's purpose is to help increase the shoe's adaptability, flexibility, and durability.


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.

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.


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.
