I loved the first Ride ISO and this version is just as good if not better. I've been running for 30 years. I have tried Hoka's, Brooks, Asics and many other brands. Saucony shoes just work better for me than any other brand. I run about 25-30km a week. I alternate between Ride ISO for slower, longer runs and Kinvara for faster runs. I recommend everyone to try on sneakers in a good store before buying online.
