Saucony Liberty ISO review

Who should buy the Saucony Liberty ISO

Optimal shoe for mild overpronators looking for the perfect balance between lightweight and robust stability. Recommended for speedier runs on shorter distances.

Who should NOT buy the shoe

Runners with a more pronounced and severe overpronation or any other foot concerns that call for all the support they can get should have a look at Saucony's Hurricane 23 or Guide 15. And if the shoe's ability to handle faster paces is still a must, then Saucony Tempus.

All of the above also have significantly thicker cushioning for long-distance endeavors.

A supportive shoe that feels neutral

Expert shoe reviewers and runners all praised the way in which this Saucony shoe made their feet supported without feeling like a stability shoe at all. Here are some of their comments:

• "barely felt on the run"
• "support aspect is very mild and the ride experience is almost neutral"
• "medial frame is minimal but offers enough to give the support I need"

They also noticed how this setup made their legs less fatigued without hitting the arch with a hard material underneath.

Responsive ride of the Liberty ISO

With its minimal stack (22 mm/18 mm) and heel-to-toe drop (4 mm), the Liberty turned out to be an impressively cushioned shoe for shorter distances at quicker paces. Runners described their experience running in this shoe as natural, energetic, and responsive. "Gives a nice spring-back feedback without going overboard," says one of them. Another one refers to it as "sturdy and stable feeling like a springboard."

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. Many reviewers have compared it to Adidas' Boost foam because the EVERUN also has small pellets fused together. However, the latter foam is described as noticeably firmer than Boost.

Lightness in every step

More than a few wearers have taken note of how light the Saucony Liberty ISO feels on the foot. The shoe tips the scales at 9.7 oz (275 g), which is lighter than stability running shoes on average (hovers around 10.5 oz / 298 g).

The ISO upper provides a snug and secure 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.

Runners couldn't be happier with the locked-in sensation that it gives:

• "locked my foot completely into place and I had no issues with my foot sliding around"
• "work well to hold the foot and adjust each area of the foot specifically"
• "midfoot panels hug and support the arch comfortably without any pressure hot spots"

At the same time, the toebox portion of the upper remains spacious enough for the toes to splay.
