The Isaac 2 is our super cushioned model that has a redesigned forefoot ART™ configuration that enhances forefoot cushioning and stride. Serves just as well as an entry level trainer as it does a daily cushioned trainer.
I have 10 years using Newton shoes (Gravity, Distance...) with fantastic results. Isaac 2 trainer, more cushioned has been a great discovery. Super comfortable and adaptable.
