trackhead, I know efficiency plays a large role in how fast a shoe wears. What I am essentially trying to do is get down to a lower heel. I have a somewhat high arch, but normal when flexed. I used to wear orthos with asics 2000 series, then went to adidas taper, then the elite, all with orthos though. I have found that I pronate much less in a shoe that has a lower heel height, but I hear the FREE really isn't that low? Eventually I would love to do all my training in a pair of H-streets, but my feet are not ready yet. I completely believe in all the logic behind the entire minimal paradigm, so are the FREE's sans orthos a step in the right direction? the only injury problems I have had in the past have been shins, and arch problems, most recent PF (which slightly tore during a recent race), but I don't want it to come back. So is going minimal the best way to strengthen my PF?
