A colleague drew this article to my attention:
It is an interesting overview of the existing data including when barefoot style may be of benefit to a runner, and ends with some advice on making the transition to minimalist shoes including technique, timing, the importance of strengthening and stretching muscles and warning signs to look out for. The writers emphasise that some runners may need longer to make the transition.
I was interested in its findings on the impact (quite literally!) of running style being as crucial as choice of footwear. Changing footwear to minimalist shoes whilst maintaining a rear foot strike is unlikely to reduce the incidence of injury.... The writers also advise caution with regard to changing running style if there are no existing signs of stress or injury; this is a view that other physiotherapists have expressed.
