I have been running regularly for 38 years. Still race.
Pro: Very light. Cool mesh. Durable soles. Nice colors. Like the company.
Con: Not enough arch support. Size up 1/2 to 1 size.

I used the shoes for fast training and some track workouts. Developed first time plantar tendon/fascial pain while using these shoes. No certain that there is a connection but stopped using the Freedom Iso and went back to the fast wearing Kinvara. Seem to be a better shoe for my very high arches.
