Carbon Fiber Shoes and Bone Stress Injuries

A study done on bone stress injuries with new carbon fiber shoes. It suggests that there is a possible link between this rather than an absolute link. The barefoot running premise was sold all positively and then slowly the report started to come in actually I got a stress fracture in my foot. If you change anything, particularly a runner's interface with the ground, you probably have to assume that you've got to go back to 40k a week even if it's not square zero.
