US trail running website, Trail Runner Nation have recorded a podcast with minimal running expert (and family doctor) Dr Mark Cucuzzella, director of the Natural Running Center... He succinctly describes the state of minimal runner as it stands and how it can be applied to runners of all abilities. It's well worth listening to understand the problems with traditional running shoes.
