Barefoot Running
The whole concept of barefoot running as been sweeping the running community recently but appears to be dying off somewhat now. It has been controversial not because it not a good thing to do but because of the unsubstantiated that the science does not support that get made for it. The has been a lot of misuse of the science by those who support barefoot running. Podiatrists and other who treat running injuries have certainly had more work since the trend to barefoot and minimalist running started, yet those promote it claim there are less injuries occurring. Given that all those who work in running injury clinics are reporting the opposite, its hard to know who to believe without some good science.
The is plenty of discussion about this on podiatry websites and blogs and sports medicine sites. There is no doubt that barefoot running is good for some people and not for others. Its all very individual.
