The models on the list so far break fairly neatly into daily trainers or racing shoes, but for Saucony, neutral running shoes like the Freedom ISO 2 target everything from easy running to all-out racing speed. With an aggressive 4 mm heel-toe offset and a full-length Everun sole for energetic bounce, the Freedom ISO 2 is ready to go as fast as you want to take it. But on easy days, the Freedom’s responsive cushioning will let you forget about the road.
