A couple people have recommeded the Adizero Pro's to me. They look nice, but I've never really gotten myself into a pair of adidas. Now I have the Asic Piraha's, and I ran Al's in them last sept no problems. so i do wear minimal shoes. I tend to train in nothing heavier then 9 oz. My old flats i ran the marathon in were the katana Racers….again, no problems. The katanas broke down quickly though, and the piranahs are too light for a half. Maybe I'll get out there and try the Pro's….Hows the fit and durability?
Interestingly enough, many of my freinds train soley in flats now too….
