Editor’s Conclusion
I personally own this shoe, and although it's not one of my favorite trail runners, it performs very well from a general standpoint. I bought the ISO in 2016 after trying out a long line of other shoes. What sold me was the forefoot breathability, while all-around being very solid. You can beat these things and they won't give in on you. They have great traction, and that's pretty visual. These will do well for you on the trail and come at a fair price. You'll get a well balanced package here.

Outsole
Outsole

Outsole

The outsole technology is one of the biggest changes to this model. The previous Xodus models integrated a Vibram outsole. For the Xodus ISO, Saucony has implemented its own outsole technology, the PWRTRAC. The traction and grip of the outsole are just as good, if not better than many other outsole technologies. These shoes can take you virtually everywhere. The durable rubber compound provides extraordinary traction and abrasion resistance. The hexagonal pattern of the lugs provides extra traction on the most demanding terrain. The rubber compound is tacky, which gives the outsole good grip on wet and muddy surfaces.
Midsole

Midsole

The midsole of the shoe is a unique Saucony technology. The Everun midsole has been used in other models of road running shoes. The Everun claims to be a breakthrough cushioning technology. The dynamic responsiveness provided by the midsole transform very soft landings to stronger takeoffs. The highly efficient energy return properties form the Everun make these shoe very responsive regardless of the terrain you are running on. A molded ComforLite sock liner provides extra cushioning throughout the full length of the shoe. It also brings extra arch support and great heel cushioning.
