I've been bouncing around the idea of training in Flats. Now that I'm getting into 50-60 mpw, I don't like the prospect of dropping $100 every other month on a pair of Adidas Supernova 7s.
I was wondering about the transition to flats, specifically in the adizero line. Are flats as durable as trainers? Should I bother phasing in Flats (alternating flats and trainers) for a month to let my feet adjust, or can I just jump straight in? What is a moderately, priced, durable pair of flats for someone who has a neutral foot?
