Post 75 miles Review: I've used this shoe for both short and long runs. Although the stack height is large, it can be used for all types of runs (easy, tempo, etc.); quiet versatile. I'm the right size and they fit just right. If you want less ground contact, these shoes are for you. Yes, the shoe has a "crack". No signs of use. Overall I am satisfied and will continue to run in these shoes. I predict this shoe will last a long time (400+ miles).
