Dr Daniel Lieberman, professor of biological anthropology at Harvard University, has been studying the growing injury crisis in the developed world for some time and has come to a startling conclusion: 'A lot of foot and knee injuries currently plaguing us are caused by people running with shoes that actually make our feet weak, cause us to over-pronate (ankle rotation) and give us knee problems.
'Until 1972, when the modern athletic shoe was invented, people ran in very thin-soled shoes, had strong feet and had a much lower incidence of knee injuries.
MY COMMENT: This is a very compelling article on running shoes. I've been running in worn out $39 Saucony's forever. No clue how many miles are on them but who cares? My new $36 Adidas Bostons are on the way so I should be good to go for another 6 months or so. In fairness, I try to stay off road as much as possible, and as I've posted before, I try not to spend more than $50 when I do buy (my one exception to that rule would be a good marathon racing shoe).
