Pros

Durability averages 4.6 out of 5 across eight reviews, with comfort, cushioning and appearance all at 4.5.
Three reviewers use it from tempo work up to marathons, one of them at 400 miles with it holding up well.
Two reviewers wanted a 4mm drop in a shoe that still offers some support, and say it is one of the few that does.

Cons

It lists at $160, above the $150 median for daily trainers for sale, and two reviewers name the price as a drawback.
Three reviewers find the outsole poor on wet, snowy or icy roads, one of them calling the traction zero.
One reviewer cannot lock down a higher instep in the ISO upper, and another has the tongue slide down.

Saucony Liberty ISO

4/5

Overall

Very soft cushy shoe, fairly light and responsive has a 4mm heel to toe drop with just a smidgen of support. The midsole is made of the same stuff they put in croc shoes but just a little heavier and a little more durable. The upper is pretty roomy can accommodate a high arch. The only negatives I would say is that the tongue slides down on occasion. All in all it is a great trainer.

Saucony Liberty Iso

4/5

Overall

I use the Liberty ISO for more of my faster runs and long races. I am a heavier runner, 180 lbs so a true racing flat does not work for me. I need a little more cushioning and support and the Liberty ISO is lighter than my normal trainer Triumph 3. The fit of the Liberty is a little more narrow than the Triumph but works for me because my foot is slightly narrow. I would feel comfortable using the Liberty for a 1/2 marathon and probably marathon if I got in shape for one. The Liberty ISO has decent forefoot cushion but still offers flexibility in the forefoot. I am generally hard on shoes and rarely get the mileage out of shoes most people do. I like the everrun midsole in the Triumph as well as the Liberty. I am happy in both shoes.

5/5

Overall

I love that there's finally a minimalist-type (lower heel-toe drop) shoe on the market for those of us who need a stability shoe. It seemed as if shoe companies have always assumed up until this point that only neutral runners would want a lower drop shoe, and most (if not all) stability shoe-wearers want a bigger heel. This stability/low drop shoe is supportive enough to save my post-tibial tendon from destruction over time, but lets me experience a comfortable and runnable low drop shoe. I love it! *note: definitely an adjustment period as I've always run in shoes with massive-feeling heels due to my stability need. I didn't switch over to this shoe cold turkey, eased into it to save calves.
